CDbCriteria Select doesn't show the field

Hello,

I have CDbCriteria


                $criteria = new CDbCriteria();

                $criteria->join = "INNER JOIN datnkapst dnk ON dnk.nokapst=t.nokapst";

                $criteria->together = true;

                $criteria->select = array('t.nosjp','dnk.nmpst as nmpst','t.flagprsklaimsjp', 'convert(varchar(11), tglsjp, 106) as tglsjp'

                            ,'t.mrpstsjp', 'convert(varchar(11), tglrjkawalsjp, 106) as tglrjkawalsjp', 't.nokapst', 't.norjkawalsjp'

                            ,'t.ppkrjkawalsjp','t.diagppk','t.bytagsjp','t.byversjp','t.politujsjp','t.catkhssjp','t.refasalsjp','t.jnspelsjp','t.flagrrwt',

                            'convert(varchar(11), tglpulangsjp, 106) as tglpulangsjp');

                //$criteria->with = array( "datnkapst" );

                $criteria->limit = $limit;

                $criteria->offset = $start;



but the field “dnk.nmpst” doesn’t show up in the json.

Already use alias, no luck.
