用于查找计数大于2的所有单个记录的SQL查询

所以我找不到任何解决办法。我已经看到许多订购和解决方案，这些都很接近，但并没有完全交付我所寻找的

我有这个：

SELECT *
FROM t1

WHERE t1.placed > '2020-12-01' AND t1.placed < '2020-12-02'

GROUP BY t1.account

HAVING count(t1.account) > 2;

现在，这正好反映了我希望看到的行，但我不希望它们组合在一起。我希望数据库给我所有单独的行。现在我试着通过删除组，但这根本不起作用。那么，我如何才能获得与上面相同的信息，但显示为单独的行而不是分组的行呢

我希望数据库给我所有单独的行

这听起来像是存在而不是伤害：

select *
from mytable t
where 
    placed > '2020-12-01' 
    and placed < '2020-12-02'
    and exists (
        select 1 
        from mytable t1 
        where 
            t1.account = t.account 
            and t1.placed > '2020-12-01' 
            and t1.placed < '2020-12-02'
            and t1.placed <> t.placed
    )

            and t1.placed > '2020-12-01' 
            and t1.placed < '2020-12-02'
            and t1.placed <> t.placed
    )

您可以使用公共表表达式检索所需的帐户，然后将其再次与accounts表联接

with accountids(account) as 
  (select account 
   from accounttable 
   where placed > '2020-12-01' and placed < '2020-12-02'
   group by account
   having count(account) > 2)
select a.* 
from accountids ids inner join accounttable a on ids.account = a.account

也许通过join的子查询，您可以轻松地解决它

select a.*
from table a
inner join (
    select itemID, Count(*)
    from table 
    where placed > '2020-12-01' and placed < '2020-12-02'
    group by itemID
    having Count(*) > 2
) b on a.ItemID = b.itemID
