1. criteria常用的sql拼接方式
$criteria = new CDbCriteria; //函数方式 $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 $criteria->addCondition("id = :id"); $criteria->params[':id']=1; //属性方式 $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 '; $criteria->distinct = FALSE; //是否唯一查询
2. 实例代码
//根据输入的名字查询爱好 public function serach_hobby($name){ $criteria=new CDbCriteria(); $criteria->addSearchCondition('aname', "$name"); $result= Hobby::model()->findAll($criteria); return $result; } 就是 where aname like '%$name%'的意思 其他: $criteria = new CDbCriteria(); $criteria->select = 'table_name,model_id,sum(amount) total'; $criteria->group = 'table_name,model_id'; $criteria->addCondition("$nIdcId=4");//也可以$criteria->condition = "$nIdcId=4"; $aResult = accessory_info::model()->findAll($criteria); $c = new CDbCriteria(); $c->select = 't.id, t.created_at, t.outsource_id, t.user_id, t.operate, t.content'; $c->join = 'LEFT JOIN outsource ON outsource.id=t.outsource_id'; $c->condition = 'outsource.idc_id IN(' . implode(',', $idc_ids) . ')'; if($last_log_id) { $c->condition .= " AND t.id > $last_log_id"; } $c->limit = 20; $c->order = 't.id DESC'; $logs = OutsourceProcessLog::model()->findAll($c);
