YII框架增删改查常用语句

//实例化db
$db = new \yii\db\Query();
//插入
$db->createCommand()->insert('user', [ 'name' => 'test', 'age' => 30, ])->execute();
//获取最后插入的id
Yii::$app->db->getLastInsertID()
//批量插入
$db->createCommand()->batchInsert('user', ['name', 'age'], [ ['test01', 30], ['test02', 20], ['test03', 25], ])->execute();
//更新
 $db->createCommand()->update('mif_model',$data,$where)->execute();
//删除
$db->createCommand()->delete('user', 'age = 30')->execute();
//获取sql语句
$db->from("$table")->where("$where")->createCommand()->getRawSql();

//查询语句
