Use with existing client

If you use the MySQL driver with existing database client, you must create the client with parameter multiStatements=true:

package main

import (
    "database/sql"

    _ "github.com/go-sql-driver/mysql"
    "github.com/chouandy/migrate"
    "github.com/chouandy/migrate/database/mysql"
    _ "github.com/chouandy/migrate/source/file"
)

func main() {
    db, _ := sql.Open("mysql", "user:password@tcp(host:port)/dbname?multiStatements=true")
    driver, _ := mysql.WithInstance(db, &mysql.Config{})
    m, _ := migrate.NewWithDatabaseInstance(
        "file:///migrations",
        "mysql",
        driver,
    )

    m.Steps(2)
}

Upgrading from v1

  1. Write down the current migration version from schema_migrations
  2. DROP TABLE schema_migrations
  3. Wrap your existing migrations in transactions (BEGIN/COMMIT) if you use multiple statements within one migration.
  4. Download and install the latest migrate version.
  5. Force the current migration version with migrate force <current_version>.
