Start logging a given logging key on the specified connection.

Übergabeparameter

$logging_key The logging key to log.

$key The database connection key for which we want to log.

Rückgabewert

The query log object. Note that the log object does support richer methods than the few exposed through the Database class, so in some cases it may be desirable to access it directly.
