Yii2 db getStats（db查询号）

Question

There is useful method getStats in Db-component Yii

$sql_stats = YII::app()->db->getStats();
echo $sql_stats[0] //the number of SQL statements executed
echo $sql_stats[1] //total time spent

Official documentation link

Is there method in Yii2 to get this information?

Answer 1

Here is equivalent for Yii 2:

$profiling = Yii::getLogger()->getDbProfiling();

$profiling[0] contains total count of DB queries, $profiling[1] - total execution time.

Note that if you want to get information about all queries at the end of request you should execute this code in right place, for example in afterAction():

public function afterAction($action, $result)
{
    $result = parent::afterAction($action, $result);

    $profiling = Yii::getLogger()->getDbProfiling();

    ...

    return $result;
}

Otherwise you will get the information according to the moment of execution this command.

Official documentation:

• getDbProfiling()
• afterAction()
