Yii CDbCriteria的常用方法總結。
$criteria = new CDbCriteria;
$criteria->addCondition("id=1"); //查詢條件,即where id = 1
$criteria->addInCondition('id', array(1,2,3,4,5)); //代表where id IN (1,2,3,4,5,);
$criteria->addNotInCondition('id', array(1,2,3,4,5));//與上面正好相法,是NOT IN
$criteria->addCondition('id=1','OR');//這是OR條件,多個條件的時候,該條件是OR而非AND
$criteria->addSearchCondition('name', '分類');//搜索條件,其實代表了。。where name like '%分類%'
$criteria->addBetweenCondition('id', 1, 4);//between 1 and 4
$criteria->compare('id', 1); //這個方法比較特殊,他會根據你的參數自動處理成addCondition或者addInCondition,
//即如果第二個參數是數組就會調用addInCondition
/**
* 傳遞變量
*/
$criteria->addCondition("id = :id");
$criteria->params[':id']=1;
/**
* 一些public vars
*/
$criteria->select = 'id,parentid,name'; //代表了要查詢的字段,默認select='*';
$criteria->join = 'xxx'; //連接表
$criteria->with = 'xxx'; //調用relations
$criteria->limit = 10; //取1條數據,如果小於0,則不作處理
$criteria->offset = 1; //兩條合並起來,則表示 limit 10 offset 1,或者代表了。limit 1,10
$criteria->order = 'xxx DESC,XXX ASC' ;//排序條件
$criteria->group = 'group 條件';
$criteria->having = 'having 條件 ';
$criteria->distinct = FALSE; //是否唯一查詢
多表查詢
$criteria=new CDbCriteria;
$criteria->alias = 'Invoice';
$criteria->join='LEFT JOIN Client ON Client.id=Invoice.clientId';
$criteria->condition='Client.businessId='. Yii::app()->userInfo->business;
