Question

there is a function used to decrease the number of sellers of a book in our project it is that function

class listab_Model_Books extends listab_Model_BaseBooks
{
    public function decreaseSeller($code)
    {
        $row = Doctrine_Query::create()
               ->from('listab_Model_Books b')
               ->where('b.code = ?',$code)
               ->fetchOne();
//            var_dump($row['seller']);
       $q = Doctrine_Query::create()
               ->from('listab_Model_Books b')
               ->set('b.seller = ?',$row['seller']-1)
               ->where('b.code = ?',$code)
               ->execute();
    }
}

when i try to use this function it gives me this error

SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens dotrine

what am i doing wrong 🙁

Edited for correctness.

I believe “set” should be used only with update, like this:

Doctrine_Query::create()
->update('listab_Model_Books b')
->set('b.seller', '?', $row['seller']-1)
->where('b.code = ?',$code)
->execute();

If what you are trying is to do an update you should use the “update” clause. Otherwise it’ll be taken as a select.
