Database::startLog

Starts logging a given logging key on the specified connection.

Parameters

$logging_key: The logging key to log.

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

Return value

DatabaseLog 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.
