在Yii中按條件排序不能正常工作

Question

我想按特定順序列出表中的值。但它在某種條件下工作，而不適用於其他條件。以下是代碼

$criteria = new CDbCriteria(); 
$criteria->condition = 'courseid =:courseid AND batchid =:batchid'; 
$criteria->params = array(':courseid' => $courseid, ':batchid' => $batchid); //Condition 
$criteria->order = 'student_rollno ASC'; //Order by student roll no 
$students = Student::model()->findAll($criteria); 

Answer 1

您可以嘗試此解決方案以解決您的問題。

$criteria = new CDbCriteria(); 
$criteria->condition = 't.courseid =:course_id AND t.batchid =:batch_id'; 
$criteria->params = array(':course_id' => $courseid, ':batch_id' => $batchid); //Condition 
$criteria->order = 't.student_rollno ASC'; //Order by student roll no 
$students = Student::model()->findAll($criteria);
