使用 DELETE 查询删除 SQL 中的记录

Question

下面是我的查询，它返回我想从表中删除的结果。

SELECT * 
FROM tableA
GROUP BY id
HAVING COUNT(*) > 5 

如何删除此查询中显示的记录？我正在考虑使用这个 DELETE 查询。

DELETE FROM tableA
WHERE 
     (SELECT * 
      FROM tableA
      GROUP BY id
      HAVING COUNT(*) > 5)

但这似乎不起作用。

Answer 1

您可以使用in：

delete from tableA
where id in (select id from tableA group by id having count(*) > 5)

Answer 2

在这种情况下，您可能需要执行以下操作：

DELETE from tableA
where [id] IN
(SELECT [id] from tableA
group by id
having count(*) > 5)
