How to remove an exception when requesting a database in yii?

Question

MySQL

there is PDO yii.
There is a code:

$sql = "select * from authorization(:login, :anketa, :edrpoy);";

        $connection=Yii::app()->dbpg;
        $command=$connection->createCommand($sql);
        $command->bindParam(":anketa",$login['anketa'],PDO::PARAM_STR);
        $command->bindParam(":login",$login['login'],PDO::PARAM_STR);
        $command->bindParam(":edrpoy",$login['edrpoy'],PDO::PARAM_STR);
        $dataReader=$command->queryRow();

So, if the sql line is not correct, then an exception is thrown. is it possible to bypass the exception and get the error into a variable?

Try/Catch to help you.
But such requests must be made through AR.

Play around with the skew() parameter. I’ll clarify right away that if you rotate a block by a certain degree, you will need to rotate the child block by the opposite degree. You will see it in the code.
