Yii的CDbCriteria查询条件用法实例

$criteria = new CDbCriteria;
$criteria->addCondition("MACID=464"); //查询条件,即where id = 1
$criteria->addInCondition('id',array(1,2,3,4,5)); //代表where id IN (1,23,5,);
$criteria->addNotInCondition('id',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('link','裸体');//搜索条件where name like '%分类%'
$criteria->addBetweenCondition('id',10000,10005);//between 10000 and 10005

$criteria->compare('id',1);? //这个办法比较特殊,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']=10;?
/**
* 一些public vars
*/?
$criteria->select = 'id,MACID,type'; //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 = 'id DESC,MACID ASC' ;//排序条件
$criteria->group = 'group type';
$criteria->having = 'having 条件 ';
$criteria->distinct = FALSE; //是否唯一查询?
return new CActiveDataProvider('visitlog',array(
? 'criteria'=>$criteria,
));
