数据模型搜索方法：

public function search(){// Warning: Please modify the following code to remove attributes that// should not be searched.$criteria=new CDbCriteria;$criteria->compare('id',$this->id);$criteria->compare('title',$this->title,true);//支持模糊查找$criteria->compare('content',$this->content,true);//支持模糊查找$criteria->compare('type',$this->type);$criteria->compare('user',$this->user,true);//支持模糊查找$criteria->compare('status',$this->status);$criteria->compare('create_data',$this->create_data,true);//支持模糊查找return new CActiveDataProvider($this, array('criteria'=>$criteria,'pagination'=>array('pageSize'=>50,),));}

定义比较运算

$criteria->compare('create_time','<='.$this->endtime),//创建早间小于等于指定时间

定义要查找的字段

//查找的结果$criteria->select = 'id,title,content,author,status,createtime',//也可以以下一种方式定义$criteria->select = array('id','title','content','author','status','createtime'),

定义填加查找条件

//定义条件$criteria->select =  'status=1',//添加匹配$criteria->compare('title',$this->title,true),//添加条件 $condition可以是数组，也可以是字符串，and可以省略$criteria->addCondition($condition,'and'),//添加IN条件 $column为字段名$criteria->addInCondition(string $column, array $values, string $operator='AND')//添加notin条件$criteria->addNotInCondition(string $column, array $values, string $operator='AND')//添加like条件$criteria->addSearchCondition(string $column, string $keyword),//添加Between条件$criteria->addBetweenCondition(string $column, string $valueStart, string $valueEnd, string $operator='AND')，

JOIN连表查询

$criteria->join = 'LEFT JOIN users ON users.id=authorID',

order查询结果排序

$criteria->order = 'createtime DESC',

group结果分组

$criteria->group =  'projectID, teamID',

having筛选分组结果分组数量

$criteria->having =  'SUM(revenue)<50000',
