database

func Clear ¶

func Clear(driver, path string) error

Clears any cached open/close errors. Returns an error if the database is currently open.

func Close ¶

func Close(db *sql.DB) error

Closes the specified database (if this is the last reference to it). If a previous Close returned an error, subsequent Closes will continue to return the error until either Open() or Clear() is called.

func Open ¶

func Open(driver, path string) (*sql.DB, error)

Returns the specified database, opening it if necessary. If opening the database fails, this function will return an error, and will not re-try opening the database unless you Clear() it.

The returned database is ref-counted; you must call Close() with the same driver/path combo to balance every successful Open(). You should not call Close() if the Open() failed.
