如何根据我的条件更新所有记录？ (我的代码不起作用)
$condition[] = ['>','position',$old_position];
$condition[] = ['<=',$new_position];
$condition[] = ['in','id',$ids];
Video::updateAll([
'position' => new \yii\db\Expression('@a := @a + 1'),],$condition);
你忘记了运算符,你应该试试：
$condition = ['and',['>',$old_position],['<=',$new_position],['in',$ids],];
