Sql server SQL:查找最小值但大于最大值

我正在处理任务历史记录，并尝试查找附加到同一记录的两个日期：1最近一次任务被批准的时间max approve；2上述批准后的首次提交日期

以下是我到目前为止的情况：

Select  
a.assn_uid,
max(b.ASSN_TRANS_DATE_ENTERED) as LastApprove, 
e.LastSubmitted 

FROM [PRJDEV_ProjectWebApp].[pub].[MSP_ASSIGNMENT_TRANSACTIONS] a
inner join [PRJDEV_ProjectWebApp].[pub].[MSP_ASSIGNMENT_TRANSACTIONS_COMMENTS] b
on a.ASSN_TRANS_UID = b.ASSN_TRANS_UID



join (select c.assn_uid,
min(d.ASSN_TRANS_DATE_ENTERED) as LastSubmitted

FROM [PRJDEV_ProjectWebApp].[pub].[MSP_ASSIGNMENT_TRANSACTIONS] c
inner join [PRJDEV_ProjectWebApp].[pub].[MSP_ASSIGNMENT_TRANSACTIONS_COMMENTS] d
on c.ASSN_TRANS_UID = d.ASSN_TRANS_UID

where c.ASSN_UID = '499879BC-28B2-E411-8B0A-00059A3C7A00'
and d.[ASSN_TRANS_COMMENT_TYPE_ENUM] = 0

group by c.assn_uid ) e
on e.ASSN_UID = a.ASSN_UID


where a.ASSN_UID = '499879BC-28B2-E411-8B0A-00059A3C7A00'
and b.[ASSN_TRANS_COMMENT_TYPE_ENUM] = 1

group by a.assn_uid, e.LastSubmitted

这很接近，但是，它给了我有史以来第一次提交任务。我确信我需要使用另一个子查询，我只是不知道如何在同一个结果中引用列

这是任务历史记录。突出显示了我试图展示的两个日期：

我不知道我能在任何合理的时间内完成您的查询，但要在特定行之后获取该行，您需要执行以下操作：

create table #submissions (
        ID int,
        DateAdded datetime,
        SubmissionType nvarchar(100)
    )
insert #submissions values
    (1, '2010-01-01', 'first ever'),
    (1, '2010-01-02', 'second'),
    (1, '2010-01-03', 'third'),
    (1, '2010-01-04', 'approve'),
    (1, '2010-01-05', 'first after approve'),
    (1, '2010-01-06', 'second after approve'),
    (1, '2010-01-07', 'third after approve')

declare @lastApprovalDate datetime

select @lastApprovalDate = MAX(DateAdded)
    from #submissions
    where
        SubmissionType = 'approve'

declare @firstAfterApprovalDate datetime
select @firstAfterApprovalDate = MIN(DateAdded)
    from #submissions
    where
        DateAdded > @lastApprovalDate

select *
    from #submissions
    where
        DateAdded = @firstAfterApprovalDate

drop table #submissions

---

通常，使用MAX获取最后一个批准日期，然后使用MIN where DateAdded>that MAX获取该日期之后的第一个日期，然后选择该日期的行。我添加了Top1，以防当时恰好有多行。不确定这在您的数据中是否可行，但为了安全起见。

在一些帮助下，我们发现我们需要在查询中增加一分钟

       final.assn_uid,
       final.LastApprove,
       min(final.SubmissionDate) FirstSubmitted
