Question

i need to know how to get success message after successful execution of sql or failure message of wrong execution.my example is below

          `
     public function actionSql()
      {          
            $table_no='1';
            $employee='1';
            $status='1';
    $connection=Yii::app()->db;
       $sql="INSERT INTO orders_transaction (table_no,employee,status) VALUES(:table_no,:employee,:status)";

     $command=$connection->createCommand($sql);
     $command->bindParam(":table_no",$table_no,PDO::PARAM_STR);
     $command->bindParam(":employee",$employee,PDO::PARAM_STR);
        $command->bindParam(":status",$status,PDO::PARAM_STR);

    $command->execute();} `

after executing i need to know is the row successfully inserted or not.
i used below one but no use its only echoing successfully not failure

if($command->execute())
   {
    echo "Successful";
   }

   else {
      echo "ERROR";
        }

so i tried this one its giving permission denied error for localhost with password” “

          $result=mysql_query($sql);

    // if successfully insert data into database, displays message "Successful".
         if($result){
              echo "Successful";

                   }

            else {
               echo "ERROR";
                  }

i hope you under stand my problem.please give any suggestion or answer.

Execute()

returns the number of affected rows(for INSERT, DELETE, UPDATE etc).

$num = $command->execute();

here $num will contain the affected number of rows.
