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：

$id = \Yii::$app->db->createCommand()->insert('表名',['car_num' => $car_num, 'lg_shop_id' => $shop_id])->execute();batchInsert()：一次添加多行// table name, column names, column valuesYii::$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：
|
1
|
... 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。
