本文實例講述了yii2.0框架數(shù)據(jù)庫操作。分享給大家供大家參考，具體如下：

$id = \Yii::$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(); |
刪除
|

|
// DELETE (table name, condition)Yii::$app->db->createCommand()->delete('user', 'status = 0')->execute(); |
查詢條件

$status = 10;$search = 'yii';$query->where(['status' => $status]);if (!empty($search)) { $query->andWhere(['like', 'title', $search]);} |
如果 $search 不為空，那么將會生成如下 SQL 語句：
|
1
|
... WHERE (`status` = 10) AND (`title` LIKE '%yii%') |
查詢以及打印查詢sql

$query = new Query(); $query->from('{{%shop_info}}'); $query->where('shop_type=1'); $query->select('shop_name'); $rea = $query->all();//查詢 $res = $query->createCommand();//打印sql echo $res->sql;die; var_dump($rea);die; |
希望本文所述對大家基于Yii框架的PHP程序設(shè)計有所幫助。
