MDB execute multiple

Hi Lukas, Running an executeMultiple() gives me an error - Query set: it was not specified a valid argument number- when my quert looks like this:

       $query = 'UPDATE docsections SET section_id='.$db->getIntegerValue($move_to).' WHERE doc_id=!';
       $pquery = $db->prepareQuery($query);
       $result = $db->executeMultiple($pquery, null, $doc_id);

It works like this:

       $query = 'UPDATE docsections SET section_id='.$db->getIntegerValue($move_to).' WHERE doc_id=?';
       $pquery = $db->prepareQuery($query);
       $result = $db->executeMultiple($pquery, null, $doc_id);

I thought I could use the ! in MDB to identify integers. Here's the debug output 1 PrepareQuery: UPDATE docsections SET section_id=35 WHERE doc_id=! Jeroen
