migration

go-migration

Go library for database schema migrations.

Reads sql files from a directory and imports them to the database. Files that have been already imported are skipped.

This has currently been tested only with PostgreSQL but should work with other databases.

Import

import "gopkg.in/tkorri/go-migration.v2"

Usage

The migration is executed with Upgrade method.

import (
    "gopkg.in/tkorri/go-migration.v2"
)

database, err := sql.Open("postgres", "user=example password=example dbname=example sslmode=disable")
if err != nil {
    return err
}

err = migration.Upgrade(database, "example")
if err != nil {
    return err
}

Or if you want to tweak the configurations you can use UpgradeDir.

config := &Configuration{
    Project:   "example",
    TableName: "migration_tbl",
}

err = migration.UpgradeDir(database, config, "migrations/")
if err != nil {
    return err
}

Versions

go-migration uses gopkg.in for versioning. The supported versions are:

• gopkg.in/tkorri/go-migration.v1 - The initial version
• gopkg.in/tkorri/go-migration.v2 - Added support for providing upgrade files as an array of strings
