# sql-migrate
> SQL Schema migration tool for [Go](http://golang.org/). Based on [gorp](https://github.com/go-gorp/gorp) and [goose](https://bitbucket.org/liamstask/goose).
[![Build Status](https://travis-ci.org/rubenv/sql-migrate.svg?branch=master)](https://travis-ci.org/rubenv/sql-migrate) [![GoDoc](https://godoc.org/github.com/rubenv/sql-migrate?status.png)](https://godoc.org/github.com/rubenv/sql-migrate)
Using [modl](https://github.com/jmoiron/modl)? Check out [modl-migrate](https://github.com/rubenv/modl-migrate).
## Features
* Usable as a CLI tool or as a library
* Supports SQLite, PostgreSQL, MySQL, MSSQL and Oracle databases (through [gorp](https://github.com/go-gorp/gorp))
* Can embed migrations into your application
* Migrations are defined with SQL for full flexibility
* Atomic migrations
* Up/down migrations to allow rollback
* Supports multiple database types in one project
## Installation
To install the library and command line program, use the following:
```bash
go get github.com/rubenv/sql-migrate/...
```
## Usage
### As a standalone tool
```
$ sql-migrate --help
usage: sql-migrate [--version] [--help] <command> [<args>]
Available commands are:
down Undo a database migration
redo Reapply the last migration
status Show migration status
up Migrates the database to the most recent version available
```
Each command requires a configuration file (which defaults to `dbconfig.yml`, but can be specified with the `-config` flag). This config file should specify one or more environments:
```yml
development:
dialect: sqlite3
datasource: test.db
dir: migrations/sqlite3
production:
dialect: postgres
datasource: dbname=myapp sslmode=disable
dir: migrations/postgres
table: migrations
```
The `table` setting is optional and will default to `gorp_migrations`.
The environment that will be used can be specified with the `-env` flag (defaults to `development`).
Use the `--help` flag in combination with any of the commands to get an overview of its usage:
```
$ sql-migrate up --help
Usage: sql-migrate up [options] ...
Migrates the database to the most recent version available.
Options:
-config=config.yml Configuration file to use.
-env="development" Environment.
-limit=0 Limit the number of migrations (0 = unlimited).
-dryrun Don't apply migrations, just print them.
```
The `up` command applies all available migrations. By contrast, `down` will only apply one migration by default. This behavior can be changed for both by using the `-limit` parameter.
The `redo` command will unapply the last migration and reapply it. This is useful during development, when you're writing migrations.
Use the `status` command to see the state of the applied migrations:
```bash
$ sql-migrate status
+---------------+-----------------------------------------+
| MIGRATION | APPLIED |
+---------------+-----------------------------------------+
| 1_initial.sql | 2014-09-13 08:19:06.788354925 +0000 UTC |
| 2_record.sql | no |
+---------------+-----------------------------------------+
```
### As a library
Import sql-migrate into your application:
```go
import "github.com/rubenv/sql-migrate"
```
Set up a source of migrations, this can be from memory, from a set of files or from bindata (more on that later):
```go
// Hardcoded strings in memory:
migrations := &migrate.MemoryMigrationSource{
Migrations: []*migrate.Migration{
&migrate.Migration{
Id: "123",
Up: []string{"CREATE TABLE people (id int)"},
Down: []string{"DROP TABLE people"},
},
},
}
// OR: Read migrations from a folder:
migrations := &migrate.FileMigrationSource{
Dir: "db/migrations",
}
// OR: Use migrations from bindata:
migrations := &migrate.AssetMigrationSource{
Asset: Asset,
AssetDir: AssetDir,
Dir: "migrations",
}
```
Then use the `Exec` function to upgrade your database:
```go
db, err := sql.Open("sqlite3", filename)
if err != nil {
// Handle errors!
}
n, err := migrate.Exec(db, "sqlite3", migrations, migrate.Up)
if err != nil {
// Handle errors!
}
fmt.Printf("Applied %d migrations!\n", n)
```
Note that `n` can be greater than `0` even if there is an error: any migration that succeeded will remain applied even if a later one fails.
Check [the GoDoc reference](https://godoc.org/github.com/rubenv/sql-migrate) for the full documentation.
## Writing migrations
Migrations are defined in SQL files, which contain a set of SQL statements. Special comments are used to distinguish up and down migrations.
```sql
-- +migrate Up
-- SQL in section 'Up' is executed when this migration is applied
CREATE TABLE people (id int);
-- +migrate Down
-- SQL section 'Down' is executed when this migration is rolled back
DROP TABLE people;
```
You can put multiple statements in each block, as long as you end them with a semicolon (`;`).
If you have complex statements which contain semicolons, use `StatementBegin` and `StatementEnd` to indicate boundaries:
```sql
-- +migrate Up
CREATE TABLE people (id int);
-- +migrate StatementBegin
CREATE OR REPLACE FUNCTION do_something()
returns void AS $$
DECLARE
create_query text;
BEGIN
-- Do something here
END;
$$
language plpgsql;
-- +migrate StatementEnd
-- +migrate Down
DROP FUNCTION do_something();
DROP TABLE people;
```
The order in which migrations are applied is defined through the filename: sql-migrate will sort migrations based on their name. It's recommended to use an increasing version number or a timestamp as the first part of the filename.
## Embedding migrations with [bindata](https://github.com/jteeuwen/go-bindata)
If you like your Go applications self-contained (that is: a single binary): use [bindata](https://github.com/jteeuwen/go-bindata) to embed the migration files.
Just write your migration files as usual, as a set of SQL files in a folder.
Then use bindata to generate a `.go` file with the migrations embedded:
```bash
go-bindata -pkg myapp -o bindata.go db/migrations/
```
The resulting `bindata.go` file will contain your migrations. Remember to regenerate your `bindata.go` file whenever you add/modify a migration (`go generate` will help here, once it arrives).
Use the `AssetMigrationSource` in your application to find the migrations:
```go
migrations := &migrate.AssetMigrationSource{
Asset: Asset,
AssetDir: AssetDir,
Dir: "db/migrations",
}
```
Both `Asset` and `AssetDir` are functions provided by bindata.
Then proceed as usual.
## Extending
Adding a new migration source means implementing `MigrationSource`.
```go
type MigrationSource interface {
FindMigrations() ([]*Migration, error)
}
```
The resulting slice of migrations will be executed in the given order, so it should usually be sorted by the `Id` field.

To install the library and command line program, use the following:
go get github.com/rubenv/sql-migrate/...
Command-line tool
The main command is called sql-migrate.
$ sql-migrate --help
usage: sql-migrate [--version] [--help] <command> [<args>]
Available commands are:
down Undo a database migration
redo Reapply the last migration
status Show migration status
up Migrates the database to the most recent version available
Each command requires a configuration file (which defaults to dbconfig.yml, but can be specified with the -config flag). This config file should specify one or more environments:
development:

The environment that will be used can be specified with the -env flag (defaults to development).
Use the --help flag in combination with any of the commands to get an overview of its usage:
$ sql-migrate up --help
Usage: sql-migrate up [options] ...
Migrates the database to the most recent version available.

The up command applies all available migrations. By contrast, down will only apply one migration by default. This behavior can be changed for both by using the -limit parameter.
The redo command will unapply the last migration and reapply it. This is useful during development, when you're writing migrations.

Library
Import sql-migrate into your application:
import "github.com/rubenv/sql-migrate"
Set up a source of migrations, this can be from memory, from a set of files or from bindata (more on that later):
// Hardcoded strings in memory:
migrations := &migrate.MemoryMigrationSource{
Migrations: []*migrate.Migration{
&migrate.Migration{
Id: "123",
Up: []string{"CREATE TABLE people (id int)"},
Down: []string{"DROP TABLE people"},
},
},
}
// OR: Read migrations from a folder:
migrations := &migrate.FileMigrationSource{
Dir: "db/migrations",
}
// OR: Use migrations from bindata:
migrations := &migrate.AssetMigrationSource{
Asset: Asset,
AssetDir: AssetDir,
Dir: "migrations",
}
Then use the Exec function to upgrade your database:
db, err := sql.Open("sqlite3", filename)
if err != nil {
// Handle errors!
}
n, err := migrate.Exec(db, "sqlite3", migrations, migrate.Up)
if err != nil {
// Handle errors!
}
fmt.Printf("Applied %d migrations!\n", n)
Note that n can be greater than 0 even if there is an error: any migration that succeeded will remain applied even if a later one fails.
The full set of capabilities can be found in the API docs below.
Writing migrations
Migrations are defined in SQL files, which contain a set of SQL statements. Special comments are used to distinguish up and down migrations.
-- +migrate Up
-- SQL in section 'Up' is executed when this migration is applied
CREATE TABLE people (id int);
-- +migrate Down
-- SQL section 'Down' is executed when this migration is rolled back
DROP TABLE people;
You can put multiple statements in each block, as long as you end them with a semicolon (;).
If you have complex statements which contain semicolons, use StatementBegin and StatementEnd to indicate boundaries:
-- +migrate Up
CREATE TABLE people (id int);
-- +migrate StatementBegin
CREATE OR REPLACE FUNCTION do_something()
returns void AS $$
DECLARE
create_query text;
BEGIN
-- Do something here
END;
$$
language plpgsql;
-- +migrate StatementEnd
-- +migrate Down
DROP FUNCTION do_something();
DROP TABLE people;
The order in which migrations are applied is defined through the filename: sql-migrate will sort migrations based on their name. It's recommended to use an increasing version number or a timestamp as the first part of the filename.
Embedding migrations with bindata
If you like your Go applications self-contained (that is: a single binary): use bindata (https://github.com/jteeuwen/go-bindata) to embed the migration files.
Just write your migration files as usual, as a set of SQL files in a folder.
Then use bindata to generate a .go file with the migrations embedded:
go-bindata -pkg myapp -o bindata.go db/migrations/
The resulting bindata.go file will contain your migrations. Remember to regenerate your bindata.go file whenever you add/modify a migration (go generate will help here, once it arrives).
Use the AssetMigrationSource in your application to find the migrations:
migrations := &migrate.AssetMigrationSource{
Asset: Asset,
AssetDir: AssetDir,
Dir: "db/migrations",
}
Both Asset and AssetDir are functions provided by bindata.
Then proceed as usual.
Extending
Adding a new migration source means implementing MigrationSource.

# Go Relational Persistence
[![build status](https://secure.travis-ci.org/go-gorp/gorp.png)](http://travis-ci.org/go-gorp/gorp)
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.
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.
* Bind struct fields to table columns via API or tag
* Support for embedded structs
* Support for transactions
* Forward engineer db schema from structs (great for unit tests)
* Pre/post insert/update/delete hooks
* Automatically generate insert/update/delete statements for a struct
* Automatic binding of auto increment PKs back to struct after insert
* Delete by primary key(s)
* Select by primary key(s)
* Optional trace sql logging
* Bind arbitrary SQL queries to a struct
* Bind slice to SELECT query results without type assertions
* Use positional or named bind parameters in custom SELECT queries
* Optional optimistic locking using a version column (for update/deletes)
## Installation
# install the library:
go get gopkg.in/gorp.v1
// use in your .go code:
import (
"gopkg.in/gorp.v1"
)
## Versioning
This project provides a stable release (v1.x tags) and a bleeding edge codebase (master).
`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.
## API Documentation
Full godoc output from the latest v1 release is available here:
https://godoc.org/gopkg.in/gorp.v1
For the latest code in master:
https://godoc.org/github.com/go-gorp/gorp
## Quickstart
```go
package main
import (
"database/sql"
"gopkg.in/gorp.v1"
_ "github.com/mattn/go-sqlite3"
"log"
"time"
)
func main() {
// initialize the DbMap
dbmap := initDb()
defer dbmap.Db.Close()
// delete any existing rows
err := dbmap.TruncateTables()
checkErr(err, "TruncateTables failed")
// create two posts
p1 := newPost("Go 1.1 released!", "Lorem ipsum lorem ipsum")
p2 := newPost("Go 1.2 released!", "Lorem ipsum lorem ipsum")
// insert rows - auto increment PKs will be set properly after the insert
err = dbmap.Insert(&p1, &p2)
checkErr(err, "Insert failed")
// use convenience SelectInt
count, err := dbmap.SelectInt("select count(*) from posts")
checkErr(err, "select count(*) failed")
log.Println("Rows after inserting:", count)
// update a row
p2.Title = "Go 1.2 is better than ever"
count, err = dbmap.Update(&p2)
checkErr(err, "Update failed")
log.Println("Rows updated:", count)
// fetch one row - note use of "post_id" instead of "Id" since column is aliased
//
// Postgres users should use $1 instead of ? placeholders
// See 'Known Issues' below
//
err = dbmap.SelectOne(&p2, "select * from posts where post_id=?", p2.Id)
checkErr(err, "SelectOne failed")
log.Println("p2 row:", p2)
// fetch all rows
var posts []Post
_, err = dbmap.Select(&posts, "select * from posts order by post_id")
checkErr(err, "Select failed")
log.Println("All rows:")
for x, p := range posts {
log.Printf(" %d: %v\n", x, p)
}
// delete row by PK
count, err = dbmap.Delete(&p1)
checkErr(err, "Delete failed")
log.Println("Rows deleted:", count)
// delete row manually via Exec
_, err = dbmap.Exec("delete from posts where post_id=?", p2.Id)
checkErr(err, "Exec failed")
// confirm count is zero
count, err = dbmap.SelectInt("select count(*) from posts")
checkErr(err, "select count(*) failed")
log.Println("Row count - should be zero:", count)
log.Println("Done!")
}
type Post struct {
// db tag lets you specify the column name if it differs from the struct field
Id int64 `db:"post_id"`
Created int64
Title string
Body string
}
func newPost(title, body string) Post {
return Post{
Created: time.Now().UnixNano(),
Title: title,
Body: body,
}
}
func initDb() *gorp.DbMap {
// connect to db using standard Go database/sql API
// use whatever database/sql driver you wish
db, err := sql.Open("sqlite3", "/tmp/post_db.bin")
checkErr(err, "sql.Open failed")
// construct a gorp DbMap
dbmap := &gorp.DbMap{Db: db, Dialect: gorp.SqliteDialect{}}
// add a table, setting the table name to 'posts' and
// specifying that the Id property is an auto incrementing PK
dbmap.AddTableWithName(Post{}, "posts").SetKeys(true, "Id")
// create the table. in a production system you'd generally
// use a migration tool, or create the tables via scripts
err = dbmap.CreateTablesIfNotExists()
checkErr(err, "Create tables failed")
return dbmap
}
func checkErr(err error, msg string) {
if err != nil {
log.Fatalln(msg, err)
}
}
```
## Examples
### Mapping structs to tables
First define some types:
```go
type Invoice struct {
Id int64
Created int64
Updated int64
Memo string
PersonId int64
}
type Person struct {
Id int64
Created int64
Updated int64
FName string
LName string
}
// Example of using tags to alias fields to column names
// The 'db' value is the column name
//
// A hyphen will cause gorp to skip this field, similar to the
// Go json package.
//
// This is equivalent to using the ColMap methods:
//
// table := dbmap.AddTableWithName(Product{}, "product")
// table.ColMap("Id").Rename("product_id")
// table.ColMap("Price").Rename("unit_price")
// table.ColMap("IgnoreMe").SetTransient(true)
//
type Product struct {
Id int64 `db:"product_id"`
Price int64 `db:"unit_price"`
IgnoreMe string `db:"-"`
}
```
Then create a mapper, typically you'd do this one time at app startup:
```go
// connect to db using standard Go database/sql API
// use whatever database/sql driver you wish
db, err := sql.Open("mymysql", "tcp:localhost:3306*mydb/myuser/mypassword")
// construct a gorp DbMap
dbmap := &gorp.DbMap{Db: db, Dialect: gorp.MySQLDialect{"InnoDB", "UTF8"}}
// register the structs you wish to use with gorp
// you can also use the shorter dbmap.AddTable() if you
// don't want to override the table name
//
// SetKeys(true) means we have a auto increment primary key, which
// will get automatically bound to your struct post-insert
//
t1 := dbmap.AddTableWithName(Invoice{}, "invoice_test").SetKeys(true, "Id")
t2 := dbmap.AddTableWithName(Person{}, "person_test").SetKeys(true, "Id")
t3 := dbmap.AddTableWithName(Product{}, "product_test").SetKeys(true, "Id")
```
### Struct Embedding
gorp supports embedding structs. For example:
```go
type Names struct {
FirstName string
LastName string
}
type WithEmbeddedStruct struct {
Id int64
Names
}
es := &WithEmbeddedStruct{-1, Names{FirstName: "Alice", LastName: "Smith"}}
err := dbmap.Insert(es)
```
See the `TestWithEmbeddedStruct` function in `gorp_test.go` for a full example.
### Create/Drop Tables ###
Automatically create / drop registered tables. This is useful for unit tests
but is entirely optional. You can of course use gorp with tables created manually,
or with a separate migration tool (like goose: https://bitbucket.org/liamstask/goose).
```go
// create all registered tables
dbmap.CreateTables()
// same as above, but uses "if not exists" clause to skip tables that are
// already defined
dbmap.CreateTablesIfNotExists()
// drop
dbmap.DropTables()
```
### SQL Logging
Optionally you can pass in a logger to trace all SQL statements.
I recommend enabling this initially while you're getting the feel for what
gorp is doing on your behalf.
Gorp defines a `GorpLogger` interface that Go's built in `log.Logger` satisfies.
However, you can write your own `GorpLogger` implementation, or use a package such
as `glog` if you want more control over how statements are logged.
```go
// Will log all SQL statements + args as they are run
// The first arg is a string prefix to prepend to all log messages
dbmap.TraceOn("[gorp]", log.New(os.Stdout, "myapp:", log.Lmicroseconds))
// Turn off tracing
dbmap.TraceOff()
```
### Insert
```go
// Must declare as pointers so optional callback hooks
// can operate on your data, not copies
inv1 := &Invoice{0, 100, 200, "first order", 0}
inv2 := &Invoice{0, 100, 200, "second order", 0}
// Insert your rows
err := dbmap.Insert(inv1, inv2)
// Because we called SetKeys(true) on Invoice, the Id field
// will be populated after the Insert() automatically
fmt.Printf("inv1.Id=%d inv2.Id=%d\n", inv1.Id, inv2.Id)
```
### Update
Continuing the above example, use the `Update` method to modify an Invoice:
```go
// count is the # of rows updated, which should be 1 in this example
count, err := dbmap.Update(inv1)
```
### Delete
If you have primary key(s) defined for a struct, you can use the `Delete`
method to remove rows:
```go
count, err := dbmap.Delete(inv1)
```
### Select by Key
Use the `Get` method to fetch a single row by primary key. It returns
nil if no row is found.
```go
// fetch Invoice with Id=99
obj, err := dbmap.Get(Invoice{}, 99)
inv := obj.(*Invoice)
```
### Ad Hoc SQL
#### SELECT
`Select()` and `SelectOne()` provide a simple way to bind arbitrary queries to a slice
or a single struct.
```go
// Select a slice - first return value is not needed when a slice pointer is passed to Select()
var posts []Post
_, err := dbmap.Select(&posts, "select * from post order by id")
// You can also use primitive types
var ids []string
_, err := dbmap.Select(&ids, "select id from post")
// Select a single row.
// Returns an error if no row found, or if more than one row is found
var post Post
err := dbmap.SelectOne(&post, "select * from post where id=?", id)
```
Want to do joins? Just write the SQL and the struct. gorp will bind them:
```go
// Define a type for your join
// It *must* contain all the columns in your SELECT statement
//
// The names here should match the aliased column names you specify
// in your SQL - no additional binding work required. simple.
//
type InvoicePersonView struct {
InvoiceId int64
PersonId int64
Memo string
FName string
}
// Create some rows
p1 := &Person{0, 0, 0, "bob", "smith"}
dbmap.Insert(p1)
// notice how we can wire up p1.Id to the invoice easily
inv1 := &Invoice{0, 0, 0, "xmas order", p1.Id}
dbmap.Insert(inv1)
// Run your query
query := "select i.Id InvoiceId, p.Id PersonId, i.Memo, p.FName " +
"from invoice_test i, person_test p " +
"where i.PersonId = p.Id"
// pass a slice to Select()
var list []InvoicePersonView
_, err := dbmap.Select(&list, query)
// this should test true
expected := InvoicePersonView{inv1.Id, p1.Id, inv1.Memo, p1.FName}
if reflect.DeepEqual(list[0], expected) {
fmt.Println("Woot! My join worked!")
}
```
#### SELECT string or int64
gorp provides a few convenience methods for selecting a single string or int64.
```go
// select single int64 from db (use $1 instead of ? for postgresql)
i64, err := dbmap.SelectInt("select count(*) from foo where blah=?", blahVal)
// select single string from db:
s, err := dbmap.SelectStr("select name from foo where blah=?", blahVal)
```
#### Named bind parameters
You may use a map or struct to bind parameters by name. This is currently
only supported in SELECT queries.
```go
_, err := dbm.Select(&dest, "select * from Foo where name = :name and age = :age", map[string]interface{}{
"name": "Rob",
"age": 31,
})
```
#### UPDATE / DELETE
You can execute raw SQL if you wish. Particularly good for batch operations.
```go
res, err := dbmap.Exec("delete from invoice_test where PersonId=?", 10)
```
### Transactions
You can batch operations into a transaction:
```go
func InsertInv(dbmap *DbMap, inv *Invoice, per *Person) error {
// Start a new transaction
trans, err := dbmap.Begin()
if err != nil {
return err
}
trans.Insert(per)
inv.PersonId = per.Id
trans.Insert(inv)
// if the commit is successful, a nil error is returned
return trans.Commit()
}
```
### Hooks
Use hooks to update data before/after saving to the db. Good for timestamps:
```go
// implement the PreInsert and PreUpdate hooks
func (i *Invoice) PreInsert(s gorp.SqlExecutor) error {
i.Created = time.Now().UnixNano()
i.Updated = i.Created
return nil
}
func (i *Invoice) PreUpdate(s gorp.SqlExecutor) error {
i.Updated = time.Now().UnixNano()
return nil
}
// You can use the SqlExecutor to cascade additional SQL
// Take care to avoid cycles. gorp won't prevent them.
//
// Here's an example of a cascading delete
//
func (p *Person) PreDelete(s gorp.SqlExecutor) error {
query := "delete from invoice_test where PersonId=?"
err := s.Exec(query, p.Id); if err != nil {
return err
}
return nil
}
```
Full list of hooks that you can implement:
PostGet
PreInsert
PostInsert
PreUpdate
PostUpdate
PreDelete
PostDelete
All have the same signature. for example:
func (p *MyStruct) PostUpdate(s gorp.SqlExecutor) error
### Optimistic Locking
gorp provides a simple optimistic locking feature, similar to Java's JPA, that
will raise an error if you try to update/delete a row whose `version` column
has a value different than the one in memory. This provides a safe way to do
"select then update" style operations without explicit read and write locks.
```go
// Version is an auto-incremented number, managed by gorp
// If this property is present on your struct, update
// operations will be constrained
//
// For example, say we defined Person as:
type Person struct {
Id int64
Created int64
Updated int64
FName string
LName string
// automatically used as the Version col
// use table.SetVersionCol("columnName") to map a different
// struct field as the version field
Version int64
}
p1 := &Person{0, 0, 0, "Bob", "Smith", 0}
dbmap.Insert(p1) // Version is now 1
obj, err := dbmap.Get(Person{}, p1.Id)
p2 := obj.(*Person)
p2.LName = "Edwards"
dbmap.Update(p2) // Version is now 2
p1.LName = "Howard"
// Raises error because p1.Version == 1, which is out of date
count, err := dbmap.Update(p1)
_, ok := err.(gorp.OptimisticLockError)
if ok {
// should reach this statement
// in a real app you might reload the row and retry, or
// you might propegate this to the user, depending on the desired
// semantics
fmt.Printf("Tried to update row with stale data: %v\n", err)
} else {
// some other db error occurred - log or return up the stack
fmt.Printf("Unknown db err: %v\n", err)
}
```
## Database Drivers
gorp uses the Go 1 `database/sql` package. A full list of compliant drivers is available here:
http://code.google.com/p/go-wiki/wiki/SQLDrivers
Sadly, SQL databases differ on various issues. gorp provides a Dialect interface that should be
implemented per database vendor. Dialects are provided for:
* MySQL
* PostgreSQL
* sqlite3
Each of these three databases pass the test suite. See `gorp_test.go` for example
DSNs for these three databases.
Support is also provided for:
* Oracle (contributed by @klaidliadon)
* SQL Server (contributed by @qrawl) - use driver: github.com/denisenkom/go-mssqldb
Note that these databases are not covered by CI and I (@coopernurse) have no good way to
test them locally. So please try them and send patches as needed, but expect a bit more
unpredicability.
## Known Issues
### SQL placeholder portability
Different databases use different strings to indicate variable placeholders in
prepared SQL statements. Unlike some database abstraction layers (such as JDBC),
Go's `database/sql` does not standardize this.
SQL generated by gorp in the `Insert`, `Update`, `Delete`, and `Get` methods delegates
to a Dialect implementation for each database, and will generate portable SQL.
Raw SQL strings passed to `Exec`, `Select`, `SelectOne`, `SelectInt`, etc will not be
parsed. Consequently you may have portability issues if you write a query like this:
```go
// works on MySQL and Sqlite3, but not with Postgresql
err := dbmap.SelectOne(&val, "select * from foo where id = ?", 30)
```
In `Select` and `SelectOne` you can use named parameters to work around this.
The following is portable:
```go
err := dbmap.SelectOne(&val, "select * from foo where id = :id",
map[string]interface{} { "id": 30})
```
### time.Time and time zones
gorp will pass `time.Time` fields through to the `database/sql` driver, but note that
the behavior of this type varies across database drivers.
MySQL users should be especially cautious. See: https://github.com/ziutek/mymysql/pull/77
To avoid any potential issues with timezone/DST, consider using an integer field for time
data and storing UNIX time.
## Running the tests
The included tests may be run against MySQL, Postgresql, or sqlite3.
You must set two environment variables so the test code knows which driver to
use, and how to connect to your database.
```sh
# MySQL example:
export GORP_TEST_DSN=gomysql_test/gomysql_test/abc123
export GORP_TEST_DIALECT=mysql
# run the tests
go test
# run the tests and benchmarks
go test -bench="Bench" -benchtime 10
```
Valid `GORP_TEST_DIALECT` values are: "mysql", "postgres", "sqlite3"
See the `test_all.sh` script for examples of all 3 databases. This is the script I run
locally to test the library.
## 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.
