I hesitate to call gorp an ORM. Go doesn't really have objects, at least

know anything about the relationships between your structs (at least not
yet). So the "R" is questionable too (but I use it in the name because,
well, it seemed more clever).
### Update 2015-07-01 Cleanup & feature freeze ([#270](https://github.com/go-gorp/gorp/issues/270))
The "M" is alive and well. Given some Go structs and a database, gorp
should remove a fair amount of boilerplate busy-work from your code.
We are currently cleaning up the backlog of issues and PR's. When this is done the codebase will be split into separate files and there will be breaking changes to the API's. We're also adding better tests and documentation. As a result of these changes the `master` branch will be unstable. Please use `gopkg.in/gorp.v1`. When the cleanup and changes are done, we will release `v2.0`.
I hope that gorp saves you time, minimizes the drudgery of getting data
in and out of your database, and helps your code focus on algorithms,
not infrastructure.
At this time we won't accept new feature-related pull-requests because of changes to the codebase. Please create an issue for your feature and wait until `v2.0` has been released.
For more information, please read [#270](https://github.com/go-gorp/gorp/issues/270).
## Introduction
I hesitate to call gorp an ORM. Go doesn't really have objects, at least not in the classic Smalltalk/Java sense. There goes the "O". gorp doesn't know anything about the relationships between your structs (at least not yet). So the "R" is questionable too (but I use it in the name because, well, it seemed more clever).
The "M" is alive and well. Given some Go structs and a database, gorp should remove a fair amount of boilerplate busy-work from your code.

## Installation ##
## Installation
# install the library:
go get github.com/coopernurse/gorp
go get gopkg.in/gorp.v1
// use in your .go code:
import (
"github.com/coopernurse/gorp"
"gopkg.in/gorp.v1"

## API Documentation ##
## Versioning
Full godoc output from the latest code in master is available here:
This project provides a stable release (v1.x tags) and a bleeding edge codebase (master).
http://godoc.org/github.com/coopernurse/gorp
`gopkg.in/gorp.v1` points to the latest v1.x tag. The API's for v1 are stable and shouldn't change. Development takes place at the master branch. Althought the code in master should always compile and test successfully, it might break API's. We aim to maintain backwards compatibility, but API's and behaviour might be changed to fix a bug. Also note that API's that are new in the master branch can change until released as v2.
If you want to use bleeding edge, use `github.com/go-gorp/gorp` as import path.

## Supported Go versions
This package is compatible with the last 2 major versions of Go, at this time `1.3` and `1.4`.
Any earlier versions are only supported on a best effort basis and can be dropped any time.
Go has a great compatibility promise. Upgrading your program to a newer version of Go should never really be a problem.

### Adding INDEX(es) on column(s) beyond the primary key ###
## Database Drivers ##
Indexes are frequently critical for performance. Here is how to add them to your tables.
NB: SqlServer and Oracle need testing and possible adjustment to the
CreateIndexSuffix() and DropIndexSuffix() methods to make AddIndex()
work for them.
In the example below we put an index both on the Id field, and on the AcctId field.
```
type Account struct {
Id int64
AcctId string // e.g. this might be a long uuid for portability
}
// indexType (the 2nd param to AddIndex call) is "Btree" or "Hash" for MySQL.
// demonstrate adding a second index on AcctId, and constrain that field to have unique values.
dbm.AddTable(iptab.Account{}).SetKeys(true, "Id").AddIndex("AcctIdIndex", "Btree", []string{"AcctId"}).SetUnique(true)
err = dbm.CreateTablesIfNotExists()
checkErr(err, "CreateTablesIfNotExists failed")
err = dbm.CreateIndex()
checkErr(err, "CreateIndex failed")
```
Check the effect of the CreateIndex() call in mysql:
```
$ mysql
MariaDB [test]> show create table Account;
+---------+--------------------------+
| Account | CREATE TABLE `Account` (
`Id` bigint(20) NOT NULL AUTO_INCREMENT,
`AcctId` varchar(255) DEFAULT NULL,
PRIMARY KEY (`Id`),
UNIQUE KEY `AcctIdIndex` (`AcctId`) USING BTREE <<<--- yes! index added.
) ENGINE=InnoDB DEFAULT CHARSET=utf8

## Performance ##
## Performance
gorp uses reflection to construct SQL queries and bind parameters. See the BenchmarkNativeCrud vs BenchmarkGorpCrud in gorp_test.go for a simple perf test. On my MacBook Pro gorp is about 2-3% slower than hand written SQL.

## Migration guide
#### Pre-v2 to v2
Automatic mapping of the version column used in optimistic locking has been removed as it could cause problems if the type was not int. The version column must now explicitly be set with tablemap.SetVersionCol().
