php - Yii1: How to use concat function in mysq like query -

i want use mysql concat function in like expression.
want merge firstname , lastname fullname , matched results according fullname.
have tried in yii1. below code:

    $criteria = new cdbcriteria();     $criteria->select = "*";     $criteria->select = 'concat(firstname , "" ,  lastname) fullname';     $criteria->addcondition('fullname :match');     $criteria->params = array(':match' => $query);     $models = user::model()->findall($criteria); 

below generated error message:

cdbcommand failed execute sql statement: sqlstate[42s22]: column not found: 1054 unknown column 'fullname' in 'where clause' (error 500)     cdbcommand::fetchcolumn() failed: sqlstate[42s22]: column not found: 1054 unknown column 'fullname' in 'where clause'. sql statement executed was: select count(*) `members` `t` fullname :match. 

thanks in advance

if don't need fullname afterwards, can use concat method in clause:

$criteria = new cdbcriteria(); $criteria->addcondition('concat(userid , " " , username) :match'); $criteria->params = array(':match' => $query); $models = user::model()->findall($criteria); 

however, if want keep fullname in select clause, can use alias in having clause:

$criteria = new cdbcriteria(); $criteria->select = '*, concat(userid , " " , username) fullname'; $criteria->having = 'fullname :match'; $criteria->params = array(':match' => $query); $models = user::model()->findall($criteria); 

please note user model should have fullname attribute in case, otherwise won't able access fullname field.
