如何為Yii CDbCriteria select添加條件？

Question

我使用此代碼。 我要檢查預算<0是否選擇它。

$criteria = new CDbCriteria;
$criteria->select = array('*', 'SUM(amount) as budget');
$criteria->group = 'user_id';
$debtors = Transactions::model()->findAll($criteria);

如何添加此條件？

Answer 1

采用

$criteria = new CDbCriteria;
$criteria->select = array('*', 'SUM(amount) as budget');
$criteria->having = 'budget < 0 ' ;
$criteria->group = 'user_id';
$debtors = Transactions::model()->findAll($criteria);
