Yii CDbCriteria的常用方法
$criteria = new CDbCriteria; $criteria->addCondition("id=1"); //查询条件,即where id = 1 $criteria->addInCondition('id', array(1,2,3,4,5)); //代表where id IN (1,23,,4,5,); $criteria->addNotInCondition('id', array(1,2,3,4,5));//与上面正好相法,是NOT IN $criteria->addCondition('id=1','OR');//这是OR条件,多个条件的时候,该条件是OR而非AND $criteria->addSearchCondition('name', '分类');//搜索条件,其实代表了。。where name like '%分类%' $criteria->addBetweenCondition('id', 1, 4);//between 1 and 4 $criteria->compare('id', 1); //这个方法比较特殊,他会根据你的参数自动处理成addCondition或者addInCondition, //即如果第二个参数是数组就会调用addInCondition /** * 传递变量 */ $criteria->addCondition("id = :id"); $criteria->params[':id']=1; /** * 一些public vars */ $criteria->select = 'id,parentid,name'; //代表了要查询的字段,默认select='*'; $criteria->join = 'xxx'; //连接表 $criteria->with = 'xxx'; //调用relations $criteria->limit = 10; //取1条数据,如果小于0,则不作处理 $criteria->offset = 1; //两条合并起来,则表示 limit 10 offset 1,或者代表了。limit 1,10 $criteria->order = 'xxx DESC,XXX ASC' ;//排序条件 $criteria->group = 'group 条件'; $criteria->having = 'having 条件 '; $criteria->distinct = FALSE; //是否唯一查询 多表查询 $criteria=new CDbCriteria; $criteria->alias = 'Invoice'; $criteria->join='LEFT JOIN Client ON Client.id=Invoice.clientId'; $criteria->condition='Client.businessId='.
