我想创建一个准时报告，其中我们显示员工、分支机构、准时、计划时间和 emp 是迟到还是早到还是准时。

员工同一天会有多个IN，所以需要第一个IN。
需要在两个日期之间按 EmployeeId 分组获取详细信息
需要根据分支和访问日期从tblBranchTimingEntry中选择调度时间。 IE。如果是星期天，则取 SundayIn，否则，如果是星期一，则取 MondayIn，依此类推。
此外，对于不同日期范围的分支机构，也会有不同的时间表。例如:对于一个分支机构，一个月的前 15 天他们有一个时间表，而接下来的 15 天则有另一个时间表。
所以当我们获取一个月的报告时，我们必须从 tblBranchTimingEntry 中选择 accessDate 介于 FromDate 和 ToDate 之间的计划时间
因此，对于前 15 天，计划时间将从 SundayIn 或 MondayIn 等开始......介于该日期范围和下一个日期范围的接下来 15 天之间。

我的逻辑是这样的

我们从tblAccess中选取员工在一天中的第一次IN时间
根据branch，我们从tblBranch中选择BranchEntryId
并从 tblBranchTimingEntry 中选择与 BranchEntryId 匹配的行和来自 tblBranchTimingEntry 的 fromDate 和 toDate 之间的 tblAccess 的 AccessTime。
并选择星期几对应的列，即。 SundayIn 表示星期日，依此类推。
然后我们计算时间方差，(ScheduleTime - InTime)。如果方差 > 0，则延迟那么大的方差。如果它等于 0，则 emp 准时。如果它 < 0 ，则 emp 早于计划。

需要结果

ORDER BY EmployeeName, AccessDate

这里我不知道如何将访问日期与起始日期和起始日期从 tblBranchTimingEntry 进行比较。所以我在查询中选择 ScheduleTime 和 TimeVariance 中的 TOP 1 结果。否则子查询返回多行。

还有其他方法吗？或者我如何从 tblBranchTimingEntry 获取记录，其中 accessdate 在 fromdate 和 todate 之间。

谢谢

最佳答案

我认为您的查询太复杂了。这基本上应该是通过一些奇特的逻辑连接三个表。

这个结果查询并不那么简单，因为您需要逻辑来:

每天为员工获取第一个访问权限
将员工输入的实际日期时间与预期时间进行比较
做大量的日期计算

但是，这不应该需要额外的子查询。像这样:

select a.EmployeeId, a.Branch, 
       (case when cast(cast(accesstime as date) as datetime) + sundayin) < accesstime
             then 'Late by '
             else 'Early by '
        end) +
       (cast (case when DATENAME(DW, AccessDate) = 'Sunday'
                   then datediff(second, accesstime,
                                 cast(cast(accesstime as date) as datetime) + sundayin)
                   when . . .
              end) as varchar(255)) + ' seconds'
from (select a.*,
             row_number() over (partition by employeeid, cast(accesstime as date) order by accesstime) as seqnum
      from tblAccess a
      where CAST(AccessTime AS DATE) between @DateFrom and @DateTo AND
            ReaderType = 'IN'
     ) a join
     tblBranch b
     on a.branch = b.branchid and a.seqnum = 1 join
     tblBranchTimingEntry bte
     on b.BranchTimeEntryID = bte.BranchTimeEntryID
