TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||||
|
|
||||||
|
1. Definitions.
|
||||||
|
|
||||||
|
"License" shall mean the terms and conditions for use, reproduction,
|
||||||
|
and distribution as defined by Sections 1 through 9 of this document.
|
||||||
|
|
||||||
|
"Licensor" shall mean the copyright owner or entity authorized by
|
||||||
|
the copyright owner that is granting the License.
|
||||||
|
|
||||||
|
"Legal Entity" shall mean the union of the acting entity and all
|
||||||
|
other entities that control, are controlled by, or are under common
|
||||||
|
control with that entity. For the purposes of this definition,
|
||||||
|
"control" means (i) the power, direct or indirect, to cause the
|
||||||
|
direction or management of such entity, whether by contract or
|
||||||
|
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||||
|
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||||
|
|
||||||
|
"You" (or "Your") shall mean an individual or Legal Entity
|
||||||
|
exercising permissions granted by this License.
|
||||||
|
|
||||||
|
"Source" form shall mean the preferred form for making modifications,
|
||||||
|
including but not limited to software source code, documentation
|
||||||
|
source, and configuration files.
|
||||||
|
|
||||||
|
"Object" form shall mean any form resulting from mechanical
|
||||||
|
transformation or translation of a Source form, including but
|
||||||
|
not limited to compiled object code, generated documentation,
|
||||||
|
and conversions to other media types.
|
||||||
|
|
||||||
|
"Work" shall mean the work of authorship, whether in Source or
|
||||||
|
Object form, made available under the License, as indicated by a
|
||||||
|
copyright notice that is included in or attached to the work
|
||||||
|
(an example is provided in the Appendix below).
|
||||||
|
|
||||||
|
"Derivative Works" shall mean any work, whether in Source or Object
|
||||||
|
form, that is based on (or derived from) the Work and for which the
|
||||||
|
editorial revisions, annotations, elaborations, or other modifications
|
||||||
|
represent, as a whole, an original work of authorship. For the purposes
|
||||||
|
of this License, Derivative Works shall not include works that remain
|
||||||
|
separable from, or merely link (or bind by name) to the interfaces of,
|
||||||
|
the Work and Derivative Works thereof.
|
||||||
|
|
||||||
|
"Contribution" shall mean any work of authorship, including
|
||||||
|
the original version of the Work and any modifications or additions
|
||||||
|
to that Work or Derivative Works thereof, that is intentionally
|
||||||
|
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||||
|
or by an individual or Legal Entity authorized to submit on behalf of
|
||||||
|
the copyright owner. For the purposes of this definition, "submitted"
|
||||||
|
means any form of electronic, verbal, or written communication sent
|
||||||
|
to the Licensor or its representatives, including but not limited to
|
||||||
|
communication on electronic mailing lists, source code control systems,
|
||||||
|
and issue tracking systems that are managed by, or on behalf of, the
|
||||||
|
Licensor for the purpose of discussing and improving the Work, but
|
||||||
|
excluding communication that is conspicuously marked or otherwise
|
||||||
|
designated in writing by the copyright owner as "Not a Contribution."
|
||||||
|
|
||||||
|
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||||
|
on behalf of whom a Contribution has been received by Licensor and
|
||||||
|
subsequently incorporated within the Work.
|
||||||
|
|
||||||
|
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
copyright license to reproduce, prepare Derivative Works of,
|
||||||
|
publicly display, publicly perform, sublicense, and distribute the
|
||||||
|
Work and such Derivative Works in Source or Object form.
|
||||||
|
|
||||||
|
3. Grant of Patent License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
(except as stated in this section) patent license to make, have made,
|
||||||
|
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||||
|
where such license applies only to those patent claims licensable
|
||||||
|
by such Contributor that are necessarily infringed by their
|
||||||
|
Contribution(s) alone or by combination of their Contribution(s)
|
||||||
|
with the Work to which such Contribution(s) was submitted. If You
|
||||||
|
institute patent litigation against any entity (including a
|
||||||
|
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||||
|
or a Contribution incorporated within the Work constitutes direct
|
||||||
|
or contributory patent infringement, then any patent licenses
|
||||||
|
granted to You under this License for that Work shall terminate
|
||||||
|
as of the date such litigation is filed.
|
||||||
|
|
||||||
|
4. Redistribution. You may reproduce and distribute copies of the
|
||||||
|
Work or Derivative Works thereof in any medium, with or without
|
||||||
|
modifications, and in Source or Object form, provided that You
|
||||||
|
meet the following conditions:
|
||||||
|
|
||||||
|
(a) You must give any other recipients of the Work or
|
||||||
|
Derivative Works a copy of this License; and
|
||||||
|
|
||||||
|
(b) You must cause any modified files to carry prominent notices
|
||||||
|
stating that You changed the files; and
|
||||||
|
|
||||||
|
(c) You must retain, in the Source form of any Derivative Works
|
||||||
|
that You distribute, all copyright, patent, trademark, and
|
||||||
|
attribution notices from the Source form of the Work,
|
||||||
|
excluding those notices that do not pertain to any part of
|
||||||
|
the Derivative Works; and
|
||||||
|
|
||||||
|
(d) If the Work includes a "NOTICE" text file as part of its
|
||||||
|
distribution, then any Derivative Works that You distribute must
|
||||||
|
include a readable copy of the attribution notices contained
|
||||||
|
within such NOTICE file, excluding those notices that do not
|
||||||
|
pertain to any part of the Derivative Works, in at least one
|
||||||
|
of the following places: within a NOTICE text file distributed
|
||||||
|
as part of the Derivative Works; within the Source form or
|
||||||
|
documentation, if provided along with the Derivative Works; or,
|
||||||
|
within a display generated by the Derivative Works, if and
|
||||||
|
wherever such third-party notices normally appear. The contents
|
||||||
|
of the NOTICE file are for informational purposes only and
|
||||||
|
do not modify the License. You may add Your own attribution
|
||||||
|
notices within Derivative Works that You distribute, alongside
|
||||||
|
or as an addendum to the NOTICE text from the Work, provided
|
||||||
|
that such additional attribution notices cannot be construed
|
||||||
|
as modifying the License.
|
||||||
|
|
||||||
|
You may add Your own copyright statement to Your modifications and
|
||||||
|
may provide additional or different license terms and conditions
|
||||||
|
for use, reproduction, or distribution of Your modifications, or
|
||||||
|
for any such Derivative Works as a whole, provided Your use,
|
||||||
|
reproduction, and distribution of the Work otherwise complies with
|
||||||
|
the conditions stated in this License.
|
||||||
|
|
||||||
|
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||||
|
any Contribution intentionally submitted for inclusion in the Work
|
||||||
|
by You to the Licensor shall be under the terms and conditions of
|
||||||
|
this License, without any additional terms or conditions.
|
||||||
|
Notwithstanding the above, nothing herein shall supersede or modify
|
||||||
|
the terms of any separate license agreement you may have executed
|
||||||
|
with Licensor regarding such Contributions.
|
||||||
|
|
||||||
|
6. Trademarks. This License does not grant permission to use the trade
|
||||||
|
names, trademarks, service marks, or product names of the Licensor,
|
||||||
|
except as required for reasonable and customary use in describing the
|
||||||
|
origin of the Work and reproducing the content of the NOTICE file.
|
||||||
|
|
||||||
|
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||||
|
agreed to in writing, Licensor provides the Work (and each
|
||||||
|
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||||
|
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||||
|
implied, including, without limitation, any warranties or conditions
|
||||||
|
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||||
|
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||||
|
appropriateness of using or redistributing the Work and assume any
|
||||||
|
risks associated with Your exercise of permissions under this License.
|
||||||
|
|
||||||
|
8. Limitation of Liability. In no event and under no legal theory,
|
||||||
|
whether in tort (including negligence), contract, or otherwise,
|
||||||
|
unless required by applicable law (such as deliberate and grossly
|
||||||
|
negligent acts) or agreed to in writing, shall any Contributor be
|
||||||
|
liable to You for damages, including any direct, indirect, special,
|
||||||
|
incidental, or consequential damages of any character arising as a
|
||||||
|
result of this License or out of the use or inability to use the
|
||||||
|
Work (including but not limited to damages for loss of goodwill,
|
||||||
|
work stoppage, computer failure or malfunction, or any and all
|
||||||
|
other commercial damages or losses), even if such Contributor
|
||||||
|
has been advised of the possibility of such damages.
|
||||||
|
|
||||||
|
9. Accepting Warranty or Additional Liability. While redistributing
|
||||||
|
the Work or Derivative Works thereof, You may choose to offer,
|
||||||
|
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||||
|
or other liability obligations and/or rights consistent with this
|
||||||
|
License. However, in accepting such obligations, You may act only
|
||||||
|
on Your own behalf and on Your sole responsibility, not on behalf
|
||||||
|
of any other Contributor, and only if You agree to indemnify,
|
||||||
|
defend, and hold each Contributor harmless for any liability
|
||||||
|
incurred by, or claims asserted against, such Contributor by reason
|
||||||
|
of your accepting any such warranty or additional liability.
|
||||||
|
|
||||||
|
END OF TERMS AND CONDITIONS
|
||||||
|
|
||||||
|
APPENDIX: How to apply the Apache License to your work.
|
||||||
|
|
||||||
|
To apply the Apache License to your work, attach the following
|
||||||
|
boilerplate notice, with the fields enclosed by brackets "{}"
|
||||||
|
replaced with your own identifying information. (Don't include
|
||||||
|
the brackets!) The text should be enclosed in the appropriate
|
||||||
|
comment syntax for the file format. We also recommend that a
|
||||||
|
file or class name and description of purpose be included on the
|
||||||
|
same "printed page" as the copyright notice for easier
|
||||||
|
identification within third-party archives.

## Version 1.2 (2014-06-03)
|
||||||
|
|
||||||
|
Changes:
|
||||||
|
|
||||||
|
- We switched back to a "rolling release". `go get` installs the current master branch again
|
||||||
|
- Version v1 of the driver will not be maintained anymore. Go 1.0 is no longer supported by this driver
|
||||||
|
- Exported errors to allow easy checking from application code
|
||||||
|
- Enabled TCP Keepalives on TCP connections
|
||||||
|
- Optimized INFILE handling (better buffer size calculation, lazy init, ...)
|
||||||
|
- The DSN parser also checks for a missing separating slash
|
||||||
|
- Faster binary date / datetime to string formatting
|
||||||
|
- Also exported the MySQLWarning type
|
||||||
|
- mysqlConn.Close returns the first error encountered instead of ignoring all errors
|
||||||
|
- writePacket() automatically writes the packet size to the header
|
||||||
|
- readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets
|
||||||
|
|
||||||
|
New Features:
|
||||||
|
|
||||||
|
- `RegisterDial` allows the usage of a custom dial function to establish the network connection
|
||||||
|
- Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter
|
||||||
|
- Logging of critical errors is configurable with `SetLogger`
|
||||||
|
- Google CloudSQL support
|
||||||
|
|
||||||
|
Bugfixes:
|
||||||
|
|
||||||
|
- Allow more than 32 parameters in prepared statements
|
||||||
|
- Various old_password fixes
|
||||||
|
- Fixed TestConcurrent test to pass Go's race detection
|
||||||
|
- Fixed appendLengthEncodedInteger for large numbers
|
||||||
|
- Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo)
|
||||||
|
|
||||||
|
|
||||||
|
## Version 1.1 (2013-11-02)
|
||||||
|
|
||||||
|
Changes:
|
||||||
|
|
||||||
|
- Go-MySQL-Driver now requires Go 1.1
|
||||||
|
- Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
|
||||||
|
- Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
|
||||||
|
- `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
|
||||||
|
- DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
|
||||||
|
- Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
|
||||||
|
- Optimized the buffer for reading
|
||||||
|
- stmt.Query now caches column metadata
|
||||||
|
- New Logo
|
||||||
|
- Changed the copyright header to include all contributors
|
||||||
|
- Improved the LOAD INFILE documentation
|
||||||
|
- The driver struct is now exported to make the driver directly accessible
|
||||||
|
- Refactored the driver tests
|
||||||
|
- Added more benchmarks and moved all to a separate file
|
||||||
|
- Other small refactoring
|
||||||
|
|
||||||
|
New Features:
|
||||||
|
|
||||||
|
- Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
|
||||||
|
- Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
|
||||||
|
- Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
|
||||||
|
|
||||||
|
Bugfixes:
|
||||||
|
|
||||||
|
- Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
|
||||||
|
- Convert to DB timezone when inserting `time.Time`
|
||||||
|
- Splitted packets (more than 16MB) are now merged correctly
|
||||||
|
- Fixed false positive `io.EOF` errors when the data was fully read
|
||||||
|
- Avoid panics on reuse of closed connections
|
||||||
|
- Fixed empty string producing false nil values
|
||||||
|
- Fixed sign byte for positive TIME fields
|
||||||
|
|
||||||

|
2.3. Limitations on Grant Scope
|
||||||
|
|
||||||
|
The licenses granted in this Section 2 are the only rights granted under

Notwithstanding Section 2.1(b) above, no patent license is granted by a
|
||||||
|
Contributor:

|
its Contributions.
|
||||||

|
||||||
|

the notice requirements in Section 3.4).
|
||||||
|
|
||||||
|
2.4. Subsequent Licenses
|
||||||

||||||
|
No Contributor makes additional grants as a result of Your choice to
|

distribute the Covered Software under a subsequent version of this
|
||||||
|
License (see Section 10.2) or under the terms of a Secondary License (if
|
||||||

|
||||||
|
|
||||||
|
2.5. Representation
|
||||||
|
|
||||||

||||||
|
|
||||||
|
2.6. Fair Use
|
||||||

||||||
|

|
3. Responsibilities
|
||||||
|
-------------------
|
||||||
|
|
||||||
|
3.1. Distribution of Source Form
|
||||||
|
|
||||||
|
All distribution of Covered Software in Source Code Form, including any
|
||||||
|
Modifications that You create or to which You contribute, must be under
|
||||||
|
the terms of this License. You must inform recipients that the Source
|
||||||
|
Code Form of the Covered Software is governed by the terms of this
|
||||||
|
License, and how they can obtain a copy of this License. You may not
|
||||||
|
attempt to alter or restrict the recipients' rights in the Source Code
|
||||||
|
Form.
|
||||||
|
|
||||||
|
3.2. Distribution of Executable Form
|
||||||
|
|
||||||
|
If You distribute Covered Software in Executable Form then:
|
||||||
|
|
||||||
|
(a) such Covered Software must also be made available in Source Code
|
||||||
|
Form, as described in Section 3.1, and You must inform recipients of
|
||||||
|
the Executable Form how they can obtain a copy of such Source Code
|
||||||
|
Form by reasonable means in a timely manner, at a charge no more
|
||||||
|
than the cost of distribution to the recipient; and
|
||||||
|
|
||||||
|
(b) You may distribute such Executable Form under the terms of this
|
||||||
|
License, or sublicense it under different terms, provided that the
|
||||||
|
license for the Executable Form does not attempt to limit or alter
|
||||||
|
the recipients' rights in the Source Code Form under this License.
|
||||||
|
|
||||||
|
3.3. Distribution of a Larger Work
|
||||||
|
|
||||||
|
You may create and distribute a Larger Work under terms of Your choice,
|
||||||
|
provided that You also comply with the requirements of this License for
|
||||||
|
the Covered Software. If the Larger Work is a combination of Covered
|
||||||
|
Software with a work governed by one or more Secondary Licenses, and the
|
||||||
|
Covered Software is not Incompatible With Secondary Licenses, this
|
||||||
|
License permits You to additionally distribute such Covered Software
|
||||||
|
under the terms of such Secondary License(s), so that the recipient of
|
||||||
|
the Larger Work may, at their option, further distribute the Covered
|
||||||
|
Software under the terms of either this License or such Secondary
|
||||||
|
License(s).
|
||||||
|
|
||||||
|
3.4. Notices
|
||||||
|
|
||||||
|
You may not remove or alter the substance of any license notices
|
||||||
|
(including copyright notices, patent notices, disclaimers of warranty,
|
||||||
|
or limitations of liability) contained within the Source Code Form of
|
||||||
|
the Covered Software, except that You may alter any license notices to
|
||||||
|
the extent required to remedy known factual inaccuracies.
|
||||||
|
|
||||||
|
3.5. Application of Additional Terms
|
||||||
|
|
||||||
|
You may choose to offer, and to charge a fee for, warranty, support,
|
||||||
|
indemnity or liability obligations to one or more recipients of Covered
|
||||||
|
Software. However, You may do so only on Your own behalf, and not on
|
||||||
|
behalf of any Contributor. You must make it absolutely clear that any
|
||||||
|
such warranty, support, indemnity, or liability obligation is offered by
|
||||||
|
You alone, and You hereby agree to indemnify every Contributor for any
|
||||||
|
liability incurred by such Contributor as a result of warranty, support,
|
||||||
|
indemnity or liability terms You offer. You may include additional
|
||||||
|
disclaimers of warranty and limitations of liability specific to any
|
||||||
|
jurisdiction.
|
||||||
|
|
||||||
|
4. Inability to Comply Due to Statute or Regulation
|
||||||
|
---------------------------------------------------
|
||||||
|
|
||||||
|
If it is impossible for You to comply with any of the terms of this
|
||||||
|
License with respect to some or all of the Covered Software due to
|
||||||
|
statute, judicial order, or regulation then You must: (a) comply with
|
||||||
|
the terms of this License to the maximum extent possible; and (b)
|
||||||
|
describe the limitations and the code they affect. Such description must
|
||||||
|
be placed in a text file included with all distributions of the Covered
|
||||||
|
Software under this License. Except to the extent prohibited by statute
|
||||||
|
or regulation, such description must be sufficiently detailed for a
|
||||||
|
recipient of ordinary skill to be able to understand it.
|
||||||
|
|
||||||
|
5. Termination
|
||||||
|
--------------
|
||||||
|
|
||||||
|
5.1. The rights granted under this License will terminate automatically
|
||||||
|
if You fail to comply with any of its terms. However, if You become
|
||||||
|
compliant, then the rights granted under this License from a particular
|
||||||
|
Contributor are reinstated (a) provisionally, unless and until such
|
||||||
|
Contributor explicitly and finally terminates Your grants, and (b) on an
|
||||||
|
ongoing basis, if such Contributor fails to notify You of the
|
||||||
|
non-compliance by some reasonable means prior to 60 days after You have
|
||||||
|
come back into compliance. Moreover, Your grants from a particular
|
||||||
|
Contributor are reinstated on an ongoing basis if such Contributor
|
||||||
|
notifies You of the non-compliance by some reasonable means, this is the
|
||||||
|
first time You have received notice of non-compliance with this License
|
||||||
|
from such Contributor, and You become compliant prior to 30 days after
|
||||||
|
Your receipt of the notice.
|
||||||
|
|
||||||
|
5.2. If You initiate litigation against any entity by asserting a patent
|
||||||
|
infringement claim (excluding declaratory judgment actions,
|
||||||
|
counter-claims, and cross-claims) alleging that a Contributor Version
|
||||||
|
directly or indirectly infringes any patent, then the rights granted to
|
||||||
|
You by any and all Contributors for the Covered Software under Section
|
||||||
|
2.1 of this License shall terminate.
|
||||||
|
|
||||||
|
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
|
||||||
|
end user license agreements (excluding distributors and resellers) which
|
||||||
|
have been validly granted by You or Your distributors under this License
|
||||||
|
prior to termination shall survive termination.

* 7. Limitation of Liability *
|
||||||
|
* -------------------------- *
|
||||||
|
* *
|
||||||
|
* Under no circumstances and under no legal theory, whether tort *
|
||||||
|
* (including negligence), contract, or otherwise, shall any *
|
||||||
|
* Contributor, or anyone who distributes Covered Software as *
|

|
* goodwill, work stoppage, computer failure or malfunction, or any *
|
||||||
|
* and all other commercial damages or losses, even if such party *
|
||||||
|
* shall have been informed of the possibility of such damages. This *
|
||||||
|
* limitation of liability shall not apply to liability for death or *
|
||||||
|
* personal injury resulting from such party's negligence to the *
|
||||||
|
* extent applicable law prohibits such limitation. Some *
|
||||||
|
* jurisdictions do not allow the exclusion or limitation of *
|
||||||
|
* incidental or consequential damages, so this exclusion and *
|
||||||
|
* limitation may not apply to You. *

|
||||||
|
Any litigation relating to this License may be brought only in the
|
||||||
|
courts of a jurisdiction where the defendant maintains its principal
|
||||||
|
place of business and such litigation shall be governed by laws of that
|
||||||
|
jurisdiction, without reference to its conflict-of-law provisions.
|
||||||
|
Nothing in this Section shall prevent a party's ability to bring
|
||||||
|
cross-claims or counter-claims.

This License represents the complete agreement concerning the subject
|
||||||
|
matter hereof. If any provision of this License is held to be
|
||||||
|
unenforceable, such provision shall be reformed only to the extent
|
||||||
|
necessary to make it enforceable. Any law or regulation which provides
|
||||||
|
that the language of a contract shall be construed against the drafter
|
||||||
|
shall not be used to construe this License against a Contributor.
|
||||||
|
|
||||||
|

|
---------------------------------------
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
Simple install the package to your [$GOPATH](http://code.google.com/p/go-wiki/wiki/GOPATH "GOPATH") with the [go tool](http://golang.org/cmd/go/ "go command") from shell:
|
||||||
|
```bash
|
||||||
|
$ go get github.com/go-sql-driver/mysql
|
||||||
|
```
|
||||||
|
Make sure [Git is installed](http://git-scm.com/downloads) on your machine and in your system's `PATH`.
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](http://golang.org/pkg/database/sql) API then.
|
||||||
|
|
||||||
|
Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name) as `dataSourceName`:
|
||||||
|
```go
|
||||||
|
import "database/sql"
|
||||||
|
import _ "github.com/go-sql-driver/mysql"
|
||||||
|
|
||||||
|
db, err := sql.Open("mysql", "user:password@/dbname")
|
||||||
|
```
|
||||||
|
|
||||||
|
[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
|
||||||
|
|
||||||
|
|
||||||
|
### DSN (Data Source Name)
|
||||||
|
|
||||||
|
The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets):
|
||||||
|
```
|
||||||
|
[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...¶mN=valueN]
|
||||||
|
```
|
||||||
|
|
||||||
|
A DSN in its fullest form:
|
||||||
|
```
|
||||||
|
username:password@protocol(address)/dbname?param=value
|
||||||
|
```
|
||||||
|
|
||||||
|
Except for the databasename, all values are optional. So the minimal DSN is:
|
||||||
|
```
|
||||||
|
/dbname
|
||||||
|
```
|
||||||
|
|
||||||
|
If you do not want to preselect a database, leave `dbname` empty:
|
||||||
|
```
|
||||||
|
/
|
||||||
|
```
|
||||||
|
This has the same effect as an empty DSN string:
|
||||||
|
```
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
Alternatively, [Config.FormatDSN](https://godoc.org/github.com/go-sql-driver/mysql#Config.FormatDSN) can be used to create a DSN string by filling a struct.
|
||||||
|
|
||||||
|
#### Password
|
||||||
|
Passwords can consist of any character. Escaping is **not** necessary.
|
||||||
|
|
||||||
|
#### Protocol
|
||||||
|
See [net.Dial](http://golang.org/pkg/net/#Dial) for more information which networks are available.
|
||||||
|
In general you should use an Unix domain socket if available and TCP otherwise for best performance.
|
||||||
|
|
||||||
|
#### Address
|
||||||
|
For TCP and UDP networks, addresses have the form `host:port`.
|
||||||
|
If `host` is a literal IPv6 address, it must be enclosed in square brackets.
|
||||||
|
The functions [net.JoinHostPort](http://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](http://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.
|
||||||
|
|
||||||
|
For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
|
||||||
|
|
||||||
|
#### Parameters
|
||||||
|
*Parameters are case-sensitive!*
|
||||||
|
|
||||||
|
Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`.
|
||||||
|
|
||||||
|
##### `allowAllFiles`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
`allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files.
|
||||||
|
[*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)
|
||||||
|
|
||||||
|
##### `allowCleartextPasswords`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
`allowCleartextPasswords=true` allows using the [cleartext client side plugin](http://dev.mysql.com/doc/en/cleartext-authentication-plugin.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.
|
||||||
|
|
||||||
|
##### `allowOldPasswords`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords).
|
||||||
|
|
||||||
|
##### `charset`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: string
|
||||||
|
Valid Values: <name>
|
||||||
|
Default: none
|
||||||
|
```
|
||||||
|
|
||||||
|
Sets the charset used for client-server interaction (`"SET NAMES <value>"`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
|
||||||
|
|
||||||
|
Usage of the `charset` parameter is discouraged because it issues additional queries to the server.
|
||||||
|
Unless you need the fallback behavior, please use `collation` instead.
|
||||||
|
|
||||||
|
##### `collation`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: string
|
||||||
|
Valid Values: <name>
|
||||||
|
Default: utf8_general_ci
|
||||||
|
```
|
||||||
|
|
||||||
|
Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
|
||||||
|
|
||||||
|
A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
|
||||||
|
|
||||||
|
##### `clientFoundRows`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed.
|
||||||
|
|
||||||
|
##### `columnsWithAlias`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example:
|
||||||
|
|
||||||
|
```
|
||||||
|
SELECT u.id FROM users as u
|
||||||
|
```
|
||||||
|
|
||||||
|
will return `u.id` instead of just `id` if `columnsWithAlias=true`.
|
||||||
|
|
||||||
|
##### `interpolateParams`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`.
|
||||||
|

||||||

|
||||||
|
|
||||||
|
##### `loc`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: string
|
||||||
|
Valid Values: <escaped name>
|
||||||
|
Default: UTC
|
||||||
|
```
|
||||||
|
|
||||||
|
Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](http://golang.org/pkg/time/#LoadLocation) for details.
|
||||||
|
|
||||||
|
Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter.
|
||||||
|
|
||||||
|
Please keep in mind, that param values must be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`.
|
||||||
|
|
||||||
|
##### `multiStatements`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded.
|
||||||
|
|
||||||
|
When `multiStatements` is used, `?` parameters must only be used in the first statement.
|
||||||
|
|
||||||
|
|
||||||
|
##### `parseTime`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
|
||||||
|
|
||||||
|
|
||||||
|
##### `readTimeout`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: decimal number
|
||||||
|
Default: 0
|
||||||
|
```
|
||||||
|
|
||||||
|
I/O read timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*.
|
||||||
|
|
||||||
|
|
||||||
|
##### `strict`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool
|
||||||
|
Valid Values: true, false
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
`strict=true` enables the strict mode in which MySQL warnings are treated as errors.
|
||||||
|
|
||||||
|
By default MySQL also treats notes as warnings. Use [`sql_notes=false`](http://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_sql_notes) to ignore notes. See the [examples](#examples) for an DSN example.
|
||||||
|
|
||||||
|
|
||||||
|
##### `timeout`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: decimal number
|
||||||
|
Default: OS default
|
||||||
|
```
|
||||||
|
|
||||||
|
*Driver* side connection timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. To set a server side timeout, use the parameter [`wait_timeout`](http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_wait_timeout).
|
||||||
|
|
||||||
|
|
||||||
|
##### `tls`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: bool / string
|
||||||
|
Valid Values: true, false, skip-verify, <name>
|
||||||
|
Default: false
|
||||||
|
```
|
||||||
|
|
||||||
|
`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side). Use a custom value registered with [`mysql.RegisterTLSConfig`](http://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).
|
||||||
|
|
||||||
|
|
||||||
|
##### `writeTimeout`
|
||||||
|
|
||||||
|
```
|
||||||
|
Type: decimal number
|
||||||
|
Default: 0
|
||||||
|
```
|
||||||
|
|
||||||
|
I/O write timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*.
|
||||||
|
|
||||||
|
|
||||||
|
##### System Variables
|
||||||
|
|
||||||
|
All other parameters are interpreted as system variables:
|
||||||
|
* `autocommit`: `"SET autocommit=<value>"`
|
||||||
|
* [`time_zone`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `"SET time_zone=<value>"`
|
||||||
|
* [`tx_isolation`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `"SET tx_isolation=<value>"`
|
||||||
|
* `param`: `"SET <param>=<value>"`
|
||||||
|
|
||||||
|
*The values must be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!*
|
||||||
|
|
||||||
|
#### Examples
|
||||||
|
```
|
||||||
|
user@unix(/path/to/socket)/dbname
|
||||||
|
```
|
||||||
|
|
||||||
|
```
|
||||||
|
root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local
|
||||||
|
```
|
||||||
|
|
||||||
|
```
|
||||||
|
user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true
|
||||||
|
```
|
||||||
|
|
||||||
|
Use the [strict mode](#strict) but ignore notes:
|
||||||
|
```
|
||||||
|
user:password@/dbname?strict=true&sql_notes=false
|
||||||
|
```
|
||||||
|
|
||||||
|
TCP via IPv6:
|
||||||
|
```
|
||||||
|
user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci
|
||||||
|
```
|
||||||
|
|
||||||
|
TCP on a remote host, e.g. Amazon RDS:
|
||||||
|
```
|
||||||
|
id:password@tcp(your-amazonaws-uri.com:3306)/dbname
|
||||||
|
```
|
||||||
|
|
||||||
|
Google Cloud SQL on App Engine:
|
||||||
|
```
|
||||||
|
user@cloudsql(project-id:instance-name)/dbname
|
||||||
|
```
|
||||||
|
|
||||||
|
TCP using default port (3306) on localhost:
|
||||||
|
```
|
||||||
|
user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped
|
||||||
|
```
|
||||||
|
|
||||||
|
Use the default protocol (tcp) and host (localhost:3306):
|
||||||
|
```
|
||||||
|
user:password@/dbname
|
||||||
|
```
|
||||||
|
|
||||||
|
No Database preselected:
|
||||||
|
```
|
||||||
|
user:password@/
|
||||||
|
```
|
||||||
|
|
||||||
|
### `LOAD DATA LOCAL INFILE` support
|
||||||
|
For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
|
||||||
|
```go
|
||||||
|
import "github.com/go-sql-driver/mysql"
|
||||||
|
```
|
||||||
|
|
||||||
|
Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)).
|
||||||
|
|
||||||
|
To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore.
|
||||||
|
|
||||||
|
See the [godoc of Go-MySQL-Driver](http://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details.
|
||||||
|
|
||||||
|
|
||||||
|
### `time.Time` support
|
||||||
|
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your programm.
|
||||||
|
|
||||||
|
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](http://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
|
||||||
|
|
||||||
|
**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
|
||||||
|
|
||||||
|
Alternatively you can use the [`NullTime`](http://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
|
||||||
|
|
||||||
|
|
||||||
|
### Unicode support
|
||||||
|
Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default.
|
||||||
|
|
||||||
|
Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
|
||||||
|
|
||||||
|
Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
|
||||||
|
|
||||||
|
See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support.
|
||||||
|
|
||||||
|
|
||||||
|
## Testing / Development
|
||||||
|
To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
|
||||||
|
|
||||||
|
Go-MySQL-Driver is not feature-complete yet. Your help is very appreciated.

## Contributing to pq
|
||||||
|
|
||||||
|
`pq` has a backlog of pull requests, but contributions are still very
|
||||||
|
much welcome. You can help with patch review, submitting bug reports,
|
||||||
|
or adding new functionality. There is no formal style guide, but
|
||||||
|
please conform to the style of existing code and general Go formatting
|
||||||
|
conventions when submitting patches.
|
||||||
|
|
||||||
|
### Patch review
|
||||||
|
|
||||||
|
Help review existing open pull requests by commenting on the code or
|
||||||
|
proposed functionality.
|
||||||
|
|
||||||
|
### Bug reports
|
||||||
|
|
||||||
|
We appreciate any bug reports, but especially ones with self-contained
|
||||||
|
(doesn't depend on code outside of pq), minimal (can't be simplified
|
||||||
|
further) test cases. It's especially helpful if you can submit a pull
|
||||||
|
request with just the failing test case (you'll probably want to
|
||||||
|
pattern it after the tests in
|
||||||
|
[conn_test.go](https://github.com/lib/pq/blob/master/conn_test.go).
|
||||||
|
|
||||||
|
### New functionality
|
||||||
|
|
||||||
|
There are a number of pending patches for new functionality, so
|
||||||
|
additional feature patches will take a while to merge. Still, patches
|
||||||
|
are generally reviewed based on usefulness and complexity in addition
|
||||||
|
to time-in-queue, so if you have a knockout idea, take a shot. Feel
|
||||||
|
free to open an issue discussion your proposed patch beforehand.

## Docs
|
||||||
|
|
||||||
|
For detailed documentation and basic usage examples, please see the package
|
||||||
|
documentation at <http://godoc.org/github.com/lib/pq>.
|
||||||
|
|
||||||
|
## Tests
|
||||||
|
|
||||||
|
`go test` is used for testing. A running PostgreSQL server is
|
||||||
|
required, with the ability to log in. The default database to connect
|
||||||
|
to test with is "pqgotest," but it can be overridden using environment
|
||||||
|
variables.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
PGHOST=/run/postgresql go test github.com/lib/pq
|
||||||
|
|
||||||
|
Optionally, a benchmark suite can be run as part of the tests:
|
||||||
|
|
||||||
|
PGHOST=/run/postgresql go test -bench .
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
* SSL
|
||||||
|
* Handles bad connections for `database/sql`
|
||||||
|
* Scan `time.Time` correctly (i.e. `timestamp[tz]`, `time[tz]`, `date`)
|
||||||
|
* Scan binary blobs correctly (i.e. `bytea`)
|
||||||
|
* Package for `hstore` support
|
||||||
|
* COPY FROM support
|
||||||
|
* pq.ParseURL for converting urls to connection strings for sql.Open.
|
||||||
|
* Many libpq compatible environment variables
|
||||||
|
* Unix socket support
|
||||||
|
* Notifications: `LISTEN`/`NOTIFY`
|
||||||
|
* pgpass support
|
||||||
|
|
||||||
|
## Future / Things you can help with
|
||||||
|
|
||||||
|
* Better COPY FROM / COPY TO (see discussion in #181)
|
||||||

/*
|
||||||
|
Package pq is a pure Go Postgres driver for the database/sql package.
|
||||||
|
|
||||||
|
In most cases clients will use the database/sql package instead of
|
||||||
|
using this package directly. For example:
|
||||||
|
|
||||||
|
import (
|
||||||
|
"database/sql"
|
||||||
|
|
||||||
|
_ "github.com/lib/pq"
|
||||||
|
)
|
||||||
|
|
||||||
|
func main() {
|
||||||
|
db, err := sql.Open("postgres", "user=pqgotest dbname=pqgotest sslmode=verify-full")
|
||||||
|
if err != nil {
|
||||||
|
log.Fatal(err)
|
||||||
|
}
|
||||||
|
|
||||||
|
age := 21
|
||||||
|
rows, err := db.Query("SELECT name FROM users WHERE age = $1", age)
|
||||||
|
…
|
||||||
|
}
|
||||||
|
|
||||||
|
You can also connect to a database using a URL. For example:
|
||||||
|
|
||||||
|
db, err := sql.Open("postgres", "postgres://pqgotest:password@localhost/pqgotest?sslmode=verify-full")
|
||||||
|
|
||||||
|
|
||||||
|
Connection String Parameters
|
||||||
|
|
||||||
|
|
||||||
|
Similarly to libpq, when establishing a connection using pq you are expected to
|
||||||
|
supply a connection string containing zero or more parameters.
|
||||||
|
A subset of the connection parameters supported by libpq are also supported by pq.
|
||||||
|
Additionally, pq also lets you specify run-time parameters (such as search_path or work_mem)
|
||||||
|
directly in the connection string. This is different from libpq, which does not allow
|
||||||
|
run-time parameters in the connection string, instead requiring you to supply
|
||||||
|
them in the options parameter.
|
||||||
|
|
||||||
|
For compatibility with libpq, the following special connection parameters are
|
||||||
|
supported:
|
||||||
|
|
||||||
|
* dbname - The name of the database to connect to
|
||||||
|
* user - The user to sign in as
|
||||||
|
* password - The user's password
|
||||||
|
* host - The host to connect to. Values that start with / are for unix domain sockets. (default is localhost)
|
||||||
|
* port - The port to bind to. (default is 5432)
|
||||||
|
* sslmode - Whether or not to use SSL (default is require, this is not the default for libpq)
|
||||||
|
* fallback_application_name - An application_name to fall back to if one isn't provided.
|
||||||
|
* connect_timeout - Maximum wait for connection, in seconds. Zero or not specified means wait indefinitely.
|
||||||
|
* sslcert - Cert file location. The file must contain PEM encoded data.
|
||||||
|
* sslkey - Key file location. The file must contain PEM encoded data.
|
||||||
|
* sslrootcert - The location of the root certificate file. The file must contain PEM encoded data.
|
||||||
|
|
||||||
|
Valid values for sslmode are:
|
||||||
|
|
||||||
|
* disable - No SSL
|
||||||
|
* require - Always SSL (skip verification)
|
||||||
|
* verify-ca - Always SSL (verify that the certificate presented by the server was signed by a trusted CA)
|
||||||
|
* verify-full - Always SSL (verify that the certification presented by the server was signed by a trusted CA and the server host name matches the one in the certificate)
|
||||||
|
|
||||||
|
See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING
|
||||||
|
for more information about connection string parameters.
|
||||||
|
|
||||||
|
Use single quotes for values that contain whitespace:
|
||||||
|
|
||||||
|
"user=pqgotest password='with spaces'"
|
||||||
|
|
||||||
|
A backslash will escape the next character in values:
|
||||||
|
|
||||||
|
"user=space\ man password='it\'s valid'
|
||||||
|
|
||||||
|
Note that the connection parameter client_encoding (which sets the
|
||||||
|
text encoding for the connection) may be set but must be "UTF8",
|
||||||
|
matching with the same rules as Postgres. It is an error to provide
|
||||||
|
any other value.
|
||||||
|
|
||||||
|
In addition to the parameters listed above, any run-time parameter that can be
|
||||||
|
set at backend start time can be set in the connection string. For more
|
||||||
|
information, see
|
||||||
|
http://www.postgresql.org/docs/current/static/runtime-config.html.
|
||||||
|
|
||||||
|
Most environment variables as specified at http://www.postgresql.org/docs/current/static/libpq-envars.html
|
||||||
|
supported by libpq are also supported by pq. If any of the environment
|
||||||
|
variables not supported by pq are set, pq will panic during connection
|
||||||
|
establishment. Environment variables have a lower precedence than explicitly
|
||||||
|
provided connection parameters.
|
||||||
|
|
||||||
|
The pgpass mechanism as described in http://www.postgresql.org/docs/current/static/libpq-pgpass.html
|
||||||
|
is supported, but on Windows PGPASSFILE must be specified explicitly.
|
||||||
|
|
||||||
|
Queries
|
||||||
|
|
||||||
|
database/sql does not dictate any specific format for parameter
|
||||||
|
markers in query strings, and pq uses the Postgres-native ordinal markers,
|
||||||
|
as shown above. The same marker can be reused for the same parameter:
|
||||||
|
|
||||||
|
rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1
|
||||||
|
OR age BETWEEN $2 AND $2 + 3`, "orange", 64)
|
||||||
|
|
||||||
|
pq does not support the LastInsertId() method of the Result type in database/sql.
|
||||||
|
To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres
|
||||||
|
RETURNING clause with a standard Query or QueryRow call:
|
||||||
|
|
||||||
|
var userid int
|
||||||
|
err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age)
|
||||||
|
VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid)
|
||||||
|
|
||||||
|
For more details on RETURNING, see the Postgres documentation:
|
||||||
|
|
||||||
|
http://www.postgresql.org/docs/current/static/sql-insert.html
|
||||||
|
http://www.postgresql.org/docs/current/static/sql-update.html
|
||||||
|
http://www.postgresql.org/docs/current/static/sql-delete.html
|
||||||
|
|
||||||
|
For additional instructions on querying see the documentation for the database/sql package.
|
||||||
|
|
||||||
|
Errors
|
||||||
|
|
||||||
|
pq may return errors of type *pq.Error which can be interrogated for error details:
|
||||||
|
|
||||||
|
if err, ok := err.(*pq.Error); ok {
|
||||||
|
fmt.Println("pq error:", err.Code.Name())
|
||||||
|
}
|
||||||
|
|
||||||
|
See the pq.Error type for details.
|
||||||
|
|
||||||
|
|
||||||
|
Bulk imports
|
||||||
|
|
||||||
|
You can perform bulk imports by preparing a statement returned by pq.CopyIn (or
|
||||||
|
pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement
|
||||||
|
handle can then be repeatedly "executed" to copy data into the target table.
|
||||||
|
After all data has been processed you should call Exec() once with no arguments
|
||||||
|
to flush all buffered data. Any call to Exec() might return an error which
|
||||||
|
should be handled appropriately, but because of the internal buffering an error
|
||||||
|
returned by Exec() might not be related to the data passed in the call that
|
||||||
|
failed.
|
||||||
|
|
||||||
|
CopyIn uses COPY FROM internally. It is not possible to COPY outside of an
|
||||||
|
explicit transaction in pq.
|
||||||
|
|
||||||
|
Usage example:
|
||||||
|
|
||||||
|
txn, err := db.Begin()
|
||||||
|
if err != nil {
|
||||||
|
log.Fatal(err)
|
||||||
|
}
|
||||||
|
|
||||||
|
stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age"))
|
||||||
|
if err != nil {
|
||||||
|
log.Fatal(err)
|
||||||
|
}
|
||||||
|
|
||||||
|
for _, user := range users {
|
||||||
|
_, err = stmt.Exec(user.Name, int64(user.Age))
|
||||||
|
if err != nil {
|
||||||
|
log.Fatal(err)
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
_, err = stmt.Exec()
|
||||||
|
if err != nil {
|
||||||
|
log.Fatal(err)
|
||||||
|
}
|
||||||
|
|
||||||
|
err = stmt.Close()
|
||||||
|
if err != nil {
|
||||||
|
log.Fatal(err)
|
||||||
|
}
|
||||||
|
|
||||||
|
err = txn.Commit()
|
||||||
|
if err != nil {
|
||||||
|
log.Fatal(err)
|
||||||
|
}
|
||||||
|
|
||||||
|
|
||||||
|
Notifications
|
||||||
|
|
||||||
|
|
||||||
|
PostgreSQL supports a simple publish/subscribe model over database
|
||||||
|
connections. See http://www.postgresql.org/docs/current/static/sql-notify.html
|
||||||
|
for more information about the general mechanism.
|
||||||
|
|
||||||
|
To start listening for notifications, you first have to open a new connection
|
||||||
|
to the database by calling NewListener. This connection can not be used for
|
||||||
|
anything other than LISTEN / NOTIFY. Calling Listen will open a "notification
|
||||||
|
channel"; once a notification channel is open, a notification generated on that
|
||||||
|
channel will effect a send on the Listener.Notify channel. A notification
|
||||||
|
channel will remain open until Unlisten is called, though connection loss might
|
||||||
|
result in some notifications being lost. To solve this problem, Listener sends
|
||||||
|
a nil pointer over the Notify channel any time the connection is re-established
|
||||||
|
following a connection loss. The application can get information about the
|
||||||
|
state of the underlying connection by setting an event callback in the call to
|
||||||
|
NewListener.
|
||||||
|
|
||||||
|
A single Listener can safely be used from concurrent goroutines, which means
|
||||||
|
that there is often no need to create more than one Listener in your
|
||||||
|
application. However, a Listener is always connected to a single database, so
|
||||||
|
you will need to create a new Listener instance for every database you want to
|
||||||
|
receive notifications in.
|
||||||
|
|
||||||
|
The channel name in both Listen and Unlisten is case sensitive, and can contain
|
||||||
|
any characters legal in an identifier (see
|
||||||
|
http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
|
||||||
|
for more information). Note that the channel name will be truncated to 63
|
||||||
|
bytes by the PostgreSQL server.
|
||||||
|
|
||||||
|
You can find a complete, working example of Listener usage at
|
||||||
|
http://godoc.org/github.com/lib/pq/listen_example.

Description
|
||||||
|
-----------
|
||||||
|
|
||||||
|
sqlite3 driver conforming to the built-in database/sql interface
|
||||||
|
|
||||||
|
Installation
|
||||||
|
------------
|
||||||
|
|
||||||
|
This package can be installed with the go get command:
|
||||||
|
|
||||||
|
go get github.com/mattn/go-sqlite3
|
||||||
|
|
||||||
|
_go-sqlite3_ is *cgo* package.
|
||||||
|
If you want to build your app using go-sqlite3, you need gcc.
|
||||||
|
However, if you install _go-sqlite3_ with `go install github.com/mattn/go-sqlite3`, you don't need gcc to build your app anymore.
|
||||||
|
|
||||||

* Want to build go-sqlite3 with libsqlite3 on my linux.
|
||||||
|
|
||||||
|
Use `go build --tags "libsqlite3 linux"`
|
||||||
|
|
||||||
|
* Want to build go-sqlite3 with libsqlite3 on OS X.
|
||||||
|
|
||||||
|
Install sqlite3 from homebrew: `brew install sqlite3`
|
||||||
|
|
||||||
|
Use `go build --tags "libsqlite3 darwin"`
|
||||||
|
|
||||||
|

||||||
|
|
||||||
|
* Can't build go-sqlite3 on windows 64bit.
|
||||||
|
|
||||||
|
> Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit.
|
||||||
|
> See: https://github.com/mattn/go-sqlite3/issues/27
|
||||||
|
|
||||||
|
* Getting insert error while query is opened.
|
||||||
|
|
||||||
|
> You can pass some arguments into the connection string, for example, a URI.
|
||||||
|
> See: https://github.com/mattn/go-sqlite3/issues/39
|
||||||
|
|
||||||
|
* Do you want to cross compile? mingw on Linux or Mac?
|

SQLite3 Extension
|
||||||
|
|
||||||
|
You can write your own extension module for sqlite3. For example, below is an
|
||||||
|
extension for a Regexp matcher operation.
|
||||||
|
|
||||||
|
#include <pcre.h>
|
||||||
|
#include <string.h>
|
||||||
|
#include <stdio.h>
|
||||||
|
#include <sqlite3ext.h>
|
||||||
|
|
||||||
|
SQLITE_EXTENSION_INIT1
|
||||||
|
static void regexp_func(sqlite3_context *context, int argc, sqlite3_value **argv) {
|
||||||
|
if (argc >= 2) {
|
||||||
|
const char *target = (const char *)sqlite3_value_text(argv[1]);
|
||||||
|
const char *pattern = (const char *)sqlite3_value_text(argv[0]);
|
||||||
|
const char* errstr = NULL;
|
||||||
|
int erroff = 0;
|
||||||
|
int vec[500];
|
||||||
|
int n, rc;
|
||||||
|
pcre* re = pcre_compile(pattern, 0, &errstr, &erroff, NULL);
|
||||||
|
rc = pcre_exec(re, NULL, target, strlen(target), 0, 0, vec, 500);
|
||||||
|
if (rc <= 0) {
|
||||||
|
sqlite3_result_error(context, errstr, 0);
|
||||||
|
return;
|
||||||
|
}
|
||||||
|
sqlite3_result_int(context, 1);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
#ifdef _WIN32
|
||||||
|
__declspec(dllexport)
|
||||||
|
#endif
|
||||||
|
int sqlite3_extension_init(sqlite3 *db, char **errmsg,
|
||||||
|
const sqlite3_api_routines *api) {
|
||||||
|
SQLITE_EXTENSION_INIT2(api);
|
||||||
|
return sqlite3_create_function(db, "regexp", 2, SQLITE_UTF8,
|
||||||
|
(void*)db, regexp_func, NULL, NULL);
|
||||||
|
}
|
||||||
|
|
||||||
|
It needs to be built as a so/dll shared library. And you need to register
|
||||||
|
the extension module like below.
|
||||||
|
|
||||||
|
sql.Register("sqlite3_with_extensions",
|
||||||
|
&sqlite3.SQLiteDriver{
|
||||||
|
Extensions: []string{
|
||||||
|
"sqlite3_mod_regexp",
|
||||||
|
},
|
||||||
|
})
|
||||||
|
|
||||||
|
Then, you can use this extension.
|
||||||
|
|
||||||
|
rows, err := db.Query("select text from mytable where name regexp '^golang'")
|
||||||
|
|
||||||
|
Connection Hook
|
||||||
|
|
||||||
|
You can hook and inject your code when the connection is established. database/sql
|
||||||
|
doesn't provide a way to get native go-sqlite3 interfaces. So if you want,
|
||||||
|
you need to set ConnectHook and get the SQLiteConn.
|
||||||
|
|
||||||
|
sql.Register("sqlite3_with_hook_example",
|
||||||
|
&sqlite3.SQLiteDriver{
|
||||||
|
ConnectHook: func(conn *sqlite3.SQLiteConn) error {
|
||||||
|
sqlite3conn = append(sqlite3conn, conn)
|
||||||
|
return nil
|
||||||
|
},
|
||||||
|
})
|
||||||
|
|
||||||
|
Go SQlite3 Extensions
|
||||||
|
|
||||||
|
If you want to register Go functions as SQLite extension functions,
|
||||||
|
call RegisterFunction from ConnectHook.
|
||||||
|
|
||||||
|
regex = func(re, s string) (bool, error) {
|
||||||
|
return regexp.MatchString(re, s)
|
||||||
|
}
|
||||||
|
sql.Register("sqlite3_with_go_func",
|
||||||
|
&sqlite3.SQLiteDriver{
|
||||||
|
ConnectHook: func(conn *sqlite3.SQLiteConn) error {
|
||||||
|
return conn.RegisterFunc("regexp", regex, true)
|
||||||
|
},
|
||||||
|
})
|
||||||
|
|
||||||
|
See the documentation of RegisterFunc for more details.
