Yii模型操作之criteria查找数据库的方法

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, ), )); }

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

//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')，

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

$criteria->order = 'createtime DESC',

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

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