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 _ "github.com/go-sql-driver/mysql" 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 _ "github.com/ziutek/mymysql/godrv" 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) continue } log.Infof(ctx, "First: %v - Last: %v", firstName, lastName) } if err := rows.Err(); err != nil { log.Errorf(ctx, "Row error: %v", err) } */ package cloudsql import ( "net" ) // Dial connects to the named Cloud SQL instance. func Dial(instance string) (net.Conn, error) { return connect(instance) }
