func Open

func Open(t testing.TB, driverName, dataSourceName string) *sql.DB

Open opens a database specified by its database driver name and a driver-specific data source name, usually consisting of at least a database name and connection information.

Most users will open a database via a driver-specific connection helper function that returns a [*DB]. No database drivers are included in the Go standard library. See https://golang.org/s/sqldrivers for a list of third-party drivers.

Open may just validate its arguments without creating a connection to the database. To verify that the data source name is valid, call [DB.Ping].

The returned [DB] is safe for concurrent use by multiple goroutines and maintains its own pool of idle connections. Thus, the Open function should be called just once. It is rarely necessary to close a [DB].
