這是我的代碼：DB::table('admins')->whereIn('a_id', function ($query)        {            $query->select('a_id')->fromRaw('( select a_id, row_number() over(            partition by a_username order by a_username) as row_num from admins            ) t')                ->whereRaw('row_num > 1');        })->delete();});這是 laravel 為我查詢的內(nèi)容：delete from `admins` where `a_id` in (select `a_id` from ( select a_id, row_number() over(partition by a_username order by a_username) as row_num from admins ) t where row_num > 1));如您所見，查詢末尾有一個“)”，如果我將其刪除，它會起作用，但我該怎么做呢？？我是從這個錯誤中得到的：Illuminate\Database\QueryExceptionSQLSTATE[42000]: Syntax error or access violation: 1140 Mixing of GROUP columns (MIN(),MAX(),COUNT(),...) with no GROUP columns is illegal if there is no GROUP BY clause (SQL: delete from `admins` where `a_id` in (select `a_id` from ( select a_id, row_number() over( partition by a_username order by a_username) as row_num from admins ) t where row_num > 1))有了這個錯誤，我發(fā)現(xiàn)這里在查詢末尾有一個額外的“）”，它不是我的代碼，而且 laravel 似乎把它弄錯了。誰知道我該如何刪除它，或者如果問題出在代碼中，我在代碼中犯了什么錯誤。我的 laravel 版本是： 7.9.2 而我的 PHP 版本是 7.4.5 。
