一、新增
1、使用save()
$model = new User(); $model->name = ‘test‘; $model->phone = ‘13000000000‘; $model->email = ‘[email protected]‘; $model->save();
2、使用createCommand 原生sql
$sql = "insert into user (name, phone, email) values (‘test‘, ‘13000000000‘, ‘[email protected]‘)"; Yii::$app->db->createCommand($sql)->execute();
3、使用createCommand insert
Yii::$app->db->createCommand()->insert(‘user‘, [
‘name‘ => ‘test‘,
‘phone‘ => ‘13000000000‘,
‘email‘ => ‘[email protected]‘
])->execute();
4、批量插入
Yii::$app->db->createCommand()->batchInsert(‘user‘, [‘name‘, ‘phone‘, ‘email‘], [
[‘test1‘, ‘13000000000‘, ‘[email protected]‘],
[‘test2‘, ‘13000000001‘, ‘[email protected]‘]
])->execute();
二、删除
1、使用delete()
$user = User::find()->where([‘name‘ => ‘test‘])->one(); $user->delete();
2、使用deleteAll()批量删除
User::deleteAll([‘name‘ => ‘test‘]);
3、使用createCommand delete()
Yii::$app->db->createCommand()->delete(‘user‘, [‘name‘ => ‘test‘])->execute();
4、使用createCommand 原生sql
$sql = "delete from user where name = ‘test‘"; Yii::$app->db->createCommand($sql)->execute();
三、更新
1、使用update()
$user = User::find()->where([‘name‘ => ‘test‘])->one(); $user->phone = ‘13100000000‘; $user->update(); // 或者 $user->save();
2、使用updateAll()
User::updateAll([‘phone‘ => ‘13100000000‘], [‘name‘ => ‘test‘]);
3、使用createCommand update()
Yii::$app->db->createCommand()->update(‘user‘, [‘phone‘ => ‘13100000000‘], [‘name‘ => ‘test‘])->execute();
4、使用createCommand 原生sql
$sql = "update user set phone = ‘13100000000‘ where name = ‘test‘"; Yii::$app->db->createCommand($sql)->execute();
四、查询
1、使用model
// 查询一条记录 User::find()->select([‘name‘, ‘phone‘, ‘email‘])->where([‘phone‘ => ‘13000000000‘])->andWhere([‘like‘, ‘name‘, ‘test‘])->one(); // 查询一条记录数组返回 User::find()->where([‘name‘ => ‘test‘])->asArray()->one(); // 查询所有记录 User::find()->where([‘name‘ => ‘test‘])->all(); // 查询所有记录数组返回 User::find()->where([‘name‘ => ‘test‘])->asArray()->all();
2、使用createCommand
// 查询一条记录
Yii::$app->db->createCommand("select * from user where name = :name and phone = :phone")->bindValues([‘:name‘ => ‘test‘, ‘:phone‘ => ‘13000000000‘])->queryOne();
// 查询所有记录
Yii::$app->db->createCommand("select * from user where name = :name and phone = :phone")->bindValues([‘:name‘ => ‘test‘, ‘:phone‘ => ‘13000000000‘])->queryAll();
3、使用yii\db\Query()
(new \yii\db\Query())->from(‘user‘)->where([‘name‘ => ‘test‘])->all();
4、子查询
$subQuery = (new \yii\db\Query())->select([‘id‘])->from(‘user‘)->where([‘like‘, ‘name‘, ‘test‘])->all(); (new \yii\db\Query())->from(‘user‘)->where([‘in‘, ‘id‘, $subQuery])->all();
