I'm using a preDqlSelect() callback to add a "virtual field". But the validation of my query must be happening before the callback get fired because I can't order by that new field when I query that model. Here's my callback:\[code\]class Artist extends BaseArtist{ public function preDqlSelect(Doctrine_Event $event) { // Add title field (concatenation of first_name, last_name, and company fields) $params = $event->getParams(); $q = $event->getQuery(); $a = $params['alias']; if ( $q->contains($a.'.first_name') && $q->contains($a.'.last_name') && $q->contains($a.'.company') ) { $exists = '!ISNULL(NULLIF('.$a.'.%s, \'\'))'; $value = 'http://stackoverflow.com/questions/3639388/IFNULL('.$a.'.%1$s, \'\')'; $if = sprintf($exists, 'first_name').' OR '.sprintf($exists, 'last_name'); $thenPiece1 = sprintf($value, 'first_name').', \' \', '.sprintf($value, 'last_name'); $thenPiece2 = 'IF('.sprintf($exists, 'company').', CONCAT(\' (\', '.sprintf($value, 'company').', \')\'), \'\')'; $then = 'TRIM(CONCAT('.$thenPiece1.', '.$thenPiece2 .'))'; $else = sprintf($value, 'company'); $select = 'IF('.$if.', '.$then.', '.$else.') AS title'; $q->addSelect($select); } }// ...\[/code\]And here's my query:\[code\]$artists = Doctrine_Query::create() ->select('a.id, a.first_name, a.last_name, a.company') ->from('Artist a') ->innerJoin('a.Products p') ->where('a.active <> 0') ->andWhere('p.active <> 0') ->orderBy('a.title') ->execute();\[/code\]Here's the error I'm getting:Fatal error: Uncaught exception 'Doctrine_Query_Exception' with message 'Unknown column title' in /[REMOVED]/lib/doctrine/Doctrine/Query/Orderby.php:94 Stack trace: #0 /[REMOVED]/lib/doctrine/Doctrine/Query/Abstract.php(2077): Doctrine_Query_Orderby->parse('a.title') #1 /[REMOVED]/lib/doctrine/Doctrine/Query.php(1160): Doctrine_Query_Abstract->_processDqlQueryPart('orderby', Array) #2 /[REMOVED]/lib/doctrine/Doctrine/Query.php(1126): Doctrine_Query->buildSqlQuery(false) #3 /[REMOVED]/lib/doctrine/Doctrine/Query/Abstract.php(1137): Doctrine_Query->getSqlQuery(Array, false) #4 /[REMOVED]/lib/doctrine/Doctrine/Query/Abstract.php(1106): Doctrine_Query_Abstract->_getDqlCallbackComponents(Array) #5 /[REMOVED]/lib/doctrine/Doctrine/Query/Abstract.php(1001): Doctrine_Query_Abstract->_preQuery(Array) #6 /srv/web/museumfounda in /[REMOVED]/lib/doctrine/Doctrine/Query/Orderby.php on line 94
