Question

我让查询显示TA值，结果将显示如下

SELECT convert(varchar(10),DATEADD(second, dbo.TB_EVENT_LOG.nDateTime, '19700101 00:00:00'),103) as [date] ,left(convert(varchar(10),DATEADD(second, dbo.TB_EVENT_LOG.nDateTime, '19700101 00:00:00'),108),5) as [time],
CASE WHEN dbo.TB_EVENT_LOG.[nReaderIdn] in(539577044) THEN 'F1' WHEN dbo.TB_EVENT_LOG.[nReaderIdn] in(539577051) THEN 'F2' END AS FunctionKey,TB_USER_CUSTOMINFO.sFieldValue8 as EMPLOYEEID
FROM dbo.TB_EVENT_LOG INNER JOIN dbo.TB_USER ON dbo.TB_EVENT_LOG.nUserID = dbo.TB_USER.sUserID INNER JOIN dbo.TB_USER_CUSTOMINFO ON dbo.TB_USER.nUserIdn = dbo.TB_USER_CUSTOMINFO.nUserIdn
where nDateTime > datediff(second, '19700101 00:00:00', DATEADD(DAY, -4, getdate())) and nDateTime < datediff(second, '19700101 00:00:00', getdate())

即使每天同一位用户不止一次，结果也会显示所有出勤时间。

如果任何人可以帮助我，请仅显示每个日期的最小值F1和最大值F2，员工编号

Answer 1

为了在同一列显示结果，我做了一些更改，

setValue()

此处结果将显示每个EmployeeID的F1的最小时间值和F2的最大时间值，日期在同一列，同样，我不确定您使用的是哪种时间类型，也许您可以将当前格式转换为24小时格式化然后排序。

Answer 2

您应该在此处使用UNION来获得两个结果，并且在计算MIN和MAX时，它应位于原始日期/时间列，而不是转换后的字符串

类似的事情，但是得到了极大的简化

SELECT CONVERT(...dbo.TB_EVENT_LOG.nDateTime...) AS [date], 
       CONVERT(..., MIN(dbo.TB_EVENT_LOG.nDateTime), ...) AS [Time], empId, 'F1'
WHERE funcKey = 'F1'
GROUP BY CONVERT(...dbo.TB_EVENT_LOG.nDateTime...), empId
UNION ALL
SELECT CONVERT(...dbo.TB_EVENT_LOG.nDateTime...) AS [date], 
       CONVERT(..., MAX(dbo.TB_EVENT_LOG.nDateTime), ...) AS [Time], empId, 'F2'
WHERE funcKey = 'F2'
GROUP BY CONVERT(...dbo.TB_EVENT_LOG.nDateTime...), empId

Answer 3

按日期分组后，您可以获得预期的结果。对？

尝试一下。

SELECT [date],left(convert(varchar(10),DATEADD(second, utc, '19700101 00:00:00'),108),5) as [time], FunctionKey,TB_USER_CUSTOMINFO.sFieldValue8 as  EMPLOYEEID
  FROM (
        SELECT MMDDYYYY AS [date], nUserID, MIN(nDateTime) as utc , 'F1' AS FunctionKey
          FROM (

                SELECT convert(varchar(10),DATEADD(second, dbo.TB_EVENT_LOG.nDateTime, '19700101 00:00:00'),103) AS MMDDYYYY
                       , nUserID
                       , nDateTime
                  FROM dbo.TB_EVENT_LOG
                 WHERE nDateTime > datediff(second, '19700101 00:00:00', DATEADD(DAY, -4, getdate())) 
                       and nDateTime < datediff(second, '19700101 00:00:00', getdate())
                       and dbo.TB_EVENT_LOG.[nReaderIdn] in(539577044) ) DATE_ADDED
         GROUP BY MMDDYYYY, nUserID
         UNION ALL
        SELECT MMDDYYYY AS [date], nUserID, MAX(nDateTime) as utc , 'F2' AS FunctionKey
          FROM (
                SELECT convert(varchar(10),DATEADD(second, dbo.TB_EVENT_LOG.nDateTime, '19700101 00:00:00'),103) AS MMDDYYYY
                       , nUserID
                       , nDateTime
                  FROM dbo.TB_EVENT_LOG
                 WHERE nDateTime > datediff(second, '19700101 00:00:00', DATEADD(DAY, -4, getdate())) 
                       and nDateTime < datediff(second, '19700101 00:00:00', getdate())
                       and dbo.TB_EVENT_LOG.[nReaderIdn] in(539577051) ) DATE_ADDED
         GROUP BY MMDDYYYY, nUserID  ) TA_DATA
       INNER JOIN dbo.TB_USER ON TA_DATA.nUserID = dbo.TB_USER.sUserID 
       INNER JOIN dbo.TB_USER_CUSTOMINFO ON dbo.TB_USER.nUserIdn = dbo.TB_USER_CUSTOMINFO.nUserIdn
