Package cloudsql exposes access to Google Cloud SQL databases.

    This package does not work in App Engine "flexible environment".

    This package is intended for MySQL drivers to make App Engine-specific connections. Applications should use this package through database/sql: Select a pure Go MySQL driver that supports this package, and use sql.Open with protocol "cloudsql" and an address of the Cloud SQL instance.

    A Go MySQL driver that has been tested to work well with Cloud SQL is the go-sql-driver:

    import "database/sql"
    import _ ""
    db, err := sql.Open("mysql", "user@cloudsql(project-id:instance-name)/dbname")

    Another driver that works well with Cloud SQL is the mymysql driver:

    import "database/sql"
    import _ ""
    db, err := sql.Open("mymysql", "cloudsql:instance-name*dbname/user/password")

    Using either of these drivers, you can perform a standard SQL query. This example assumes there is a table named 'users' with columns 'first_name' and 'last_name':

    rows, err := db.Query("SELECT first_name, last_name FROM users")
    if err != nil {
    	log.Errorf(ctx, "db.Query: %v", err)
    defer rows.Close()
    for rows.Next() {
    	var firstName string
    	var lastName string
    	if err := rows.Scan(&firstName, &lastName); err != nil {
    		log.Errorf(ctx, "rows.Scan: %v", err)
    	log.Infof(ctx, "First: %v - Last: %v", firstName, lastName)
    if err := rows.Err(); err != nil {
    	log.Errorf(ctx, "Row error: %v", err)
