Update query in symfony

Suppose you want to execute query like
UPDATE tableName SET column1 = ‘abc’,column2 = ‘xyz’ WHERE column =’1′;
then you can use the below syntax to do so 🙂

$con = Propel::getConnection();

/* Here you have to set the condition for which you need to update */
$c1 = new Criteria();
$c1->add(TableNamePeer::COLUMN_NAME, $conditionForColumn1);

/* Here you have to set the column value */
$c2 = new Criteria();
$c2->add(TableNamePeer::COLUMN_TO_UPDATE, $value);

BasePeer::doUpdate($c1, $c2, $con);
