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/golang-migrate/migrate"
    "github.com/golang-migrate/migrate/database/mysql"
    _ "github.com/golang-migrate/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>.
