本文实例讲述了yii2.0框架数据库操作。分享给大家供大家参考,具体如下:
添加
$id = \Yii::$app->db ->createCommand() ->insert('表名',['car_num' => $car_num, 'lg_shop_id' => $shop_id]) ->execute(); batchInsert():一次添加多行 // table name, column names, column values Yii::$app->db->createCommand()->batchInsert('user', ['name', 'age'], [ ['Tom', 30], ['Jane', 20], ['Linda', 25], ])->execute();
修改
// UPDATE (table name, column values, condition) Yii::$app->db->createCommand()->update('user', ['status' => 1], 'age > 30')->execute();
删除
// DELETE (table name, condition) Yii::$app->db->createCommand()->delete('user', 'status = 0')->execute();
查询条件
$status = 10; $search = 'yii'; $query->where(['status' => $status]); if (!empty($search)) { $query->andWhere(['like', 'title', $search]); }
如果 $search 不为空,那么将会生成如下 SQL 语句:
... WHERE (`status` = 10) AND (`title` LIKE '%yii%')
查询以及打印查询sql
$query = new Query(); $query->from('{{%shop_info}}'); $query->where('shop_type=1'); $query->select('shop_name'); $rea = $query->all();//查询 $res = $query->createCommand();//打印sql echo $res->sql;die; var_dump($rea);die;
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
