一般在search()函数里
$criteria = new CDbCriteria;
$criteria->addCondition("username='".Yii::app()->user->name."'");//获取传递当前登录用户
$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
$criteria->compare('username',$input,true,'OR');
/** 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
