symfony1 - Symfony 1.4 Doctrine run custom query give warnings -

i try run following query follows.

 $query = "delete `ski_chalet_price` 1";       $conn = doctrine_manager::getinstance()->connection();  $stmt = $conn->prepare($query);  $stmt->execute(); 

but throws following warning.

warning: invalid argument supplied foreach() in /home/dinuka/workspace/symfony/lib/plugins/sfdoctrineplugin/lib/database/sfdoctrineconnectionprofiler.class.php on line 196  warning: join(): invalid arguments passed in /home/dinuka/workspace/symfony/lib/plugins/sfdoctrineplugin/lib/database/sfdoctrineconnectionprofiler.class.php on line 141 

this query want run.

insert ski_chalet_price  (ski_chalet_id, month, d_19,d_20,d_21,d_22,d_23,d_24,d_25,created_at) values (44,'2013-04-01',10,10,10,10,10,10,10,'2013-04-19 13:27:26')  on duplicate key update  ski_chalet_id = 44, month = '2013-04-01',d_19 = 10,d_20 = 10,d_21 = 10,d_22 = 10,d_23 = 10,d_24 = 10,d_25 = 10, updated_at = '2013-04-19 13:27:26' ; 

it not depend on query. whats issue?

i inspected code on sfdoctrineconnectionprofiler.class.php , found out execute(); needs empty set of parameters (i.e. empty array) in order not complain.

so:

$stmt->execute(); 

should be:

$stmt->execute(array()); 

note "join" word in error misleading. it's not referring sql join, php's native join() function alias of implode().
