Issue while executing few SQL queries in a row

Hi everyone )

Running this peace of code


$id = $_GET['id'];

		// get current menu order

		$sql = "SELECT menuOrder FROM categories WHERE id = $id ";

		

		$cmd =  app()->db->createCommand($sql);

		/*@var $cmd CDBCommand */

		//$cmd->bindValue('id',$id);

		$menuOrder = $cmd->queryScalar();

		

		

		$oldMenuOrder = $menuOrder + 1;

		

		// get id of next 

		$sql1 = "UPDATE categories SET menuOrder = menuOrder -1 WHERE menuOrder = $menuOrder +1 ";

		app()->db->createCommand($sql)->execute();

		 

		$sql2 = "UPDATE categories SET menuOrder = $oldMenuOrder WHERE id = $id";

		app()->db->createCommand($sql)->execute();

I gets an error:

Thank you.

My stupidity )

I try to execute() first ‘SELECT’ query after…
