MySQL查询可与Select一起正常使用，但Delete查询会根据GROUP BY的位置无限期挂起

Question

select * from table1 where ID in (
    select min(a.ID) from (select * from table1) a group by id_x, id_y, col_z having count(*) > 1)

以上查询在2.2秒内运行，返回四个结果。现在，当我将select *更改为delete时，它会无限期挂起。

delete from table1 where ID in (
    select min(a.ID) from (select * from table1) a group by id_x, id_y, col_z having count(*) > 1)

如果我在别名选择查询中移动group by子句的位置，它将不再挂起。

delete from table1 where ID in (
    select a.ID from (select min(ID) from table1 group by id_x, id_y, col_z having count(*) > 1) a)

为什么挂起？即使(select * from table1)拉动了数百万条记录，查询似乎也没有停止执行数小时。有人可以解释是什么困扰了查询吗？这使我感到困惑，因为选择查询工作正常，而删除查询挂起。
