php - Can't sort query results in ascending order -


i'm trying sort following select query in ascending order meds_name, can't figure out i'm doing wrong. it's instead sorting names start lower case letters first, , following start upper case.

query works when interpret , execute in mysql, not in yii. can see i'm going wrong:

$specs = yii::app()->db->createcommand()                 ->select("im.*,m.name meds_name,mf.name meds_freq_name,                             mr.name meds_route_name,mu.name meds_unit_name,                             concat_ws('/',im.meds_startmm,im.meds_startyyyy) meds_startdate,                             concat_ws('/',im.meds_endmm,im.meds_endyyyy) meds_enddate")                 ->from('indiv_meds im')                 ->leftjoin('meds m', 'im.meds_name=m.id')                 ->leftjoin('med_freq mf', 'im.meds_freq=mf.id')                 ->leftjoin('med_route mr', 'im.meds_route=mr.id')                 ->leftjoin('lkpmeds mu', 'im.meds_unit=mu.id')                 ->where($select_condition_declare)                 ->limit($limit, $start)                 ->order(array('meds_name asc'))                 ->queryall();

this because result sorting based on ascii code. can solve problem converting query result sorting column lowercase/uppercase:

$specs = yii::app()->db->createcommand()                 ->select("im.*, lower(m.name) meds_name,mf.name meds_freq_name,                             mr.name meds_route_name,mu.name meds_unit_name,                             concat_ws('/',im.meds_startmm,im.meds_startyyyy) meds_startdate,                             concat_ws('/',im.meds_endmm,im.meds_endyyyy) meds_enddate")                 ->from('indiv_meds im')                 ->leftjoin('meds m', 'im.meds_name=m.id')                 ->leftjoin('med_freq mf', 'im.meds_freq=mf.id')                 ->leftjoin('med_route mr', 'im.meds_route=mr.id')                 ->leftjoin('lkpmeds mu', 'im.meds_unit=mu.id')                 ->where($select_condition_declare)                 ->limit($limit, $start)                 ->order(array('meds_name asc'))                 ->queryall();
