sql - 嵌套查询出错

Question

我正在尝试在我的网站上开发一个时间表页面，这是我的数据库结构:

我想获得总小时数(TimeSheetWeeks 表的总和(timeFrom-timeTo))、总费用(TimeSheetWeeks 表的总金额)和总计(TimSheetWeeks 表的总金额+ compAllow 表的总金额)。

这是我为获得结果而编写的查询:

 ;WITH w(tot, tid, eid, fd, td, am, mw) AS
 (
 SELECT   Total = tsw.amount+ca.amount , tsw.[TimeSheetID], [EmployeeID], 
 [FromDate],[ToDate],  tsw.[Amount], SUM(DATEDIFF(MINUTE, [timeFrom],[timeTo] )) 
 FROM
 TimeSheet ts 
 INNER JOIN (
  SELECT  SUM(amount) amount, TimeSheetID 
  FROM TimeSheetWeeks
  GROUP BY TimeSheetID
  )  tsw ON ts.TimeSheetID = tsw.TimeSheetID INNER JOIN (
  SELECT  SUM(amount) amount, TimeSheetID
  FROM CompAllow
  GROUP BY TimeSheetID
  )  ca ON ts.TimeSheetID = ca.TimeSheetID INNER JOIN (
     SELECT  timeFrom, timeTo, TimeSheetID
  FROM TimeSheetWeeks
  ) AS tss ON tss.TimeSheetID=ts.TimeSheetID
  WHERE ts.TimeSheetID=6
  Group By tsw.[TimeSheetID], [EmployeeID], [FromDate], [ToDate], tsw.[Amount]
  )
  SELECT tot, tid, eid, fd, td, Amount = am,  totalHrs = RTRIM(mw/60) + ':' + 
  RIGHT('0'+ RTRIM(mw%60),2)
  FROM w;

这个查询导致错误提示

Column 'ca.amount' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

这里出了什么问题？提前谢谢。

ca.amount 列在 w CTE 中被引用，但既不聚合也不包含在 GROUP BY 子句中:

 ;WITH w(tot, tid, eid, fd, td, am, mw) AS
 (
 SELECT   Total = tsw.amount+<b><i>ca.amount</i></b> , tsw.[TimeSheetID], [EmployeeID], 
 [FromDate],[ToDate],  tsw.[Amount], SUM(DATEDIFF(MINUTE, [timeFrom],[timeTo] )) 
 FROM
 TimeSheet ts 
 INNER JOIN (
  SELECT  SUM(amount) amount, TimeSheetID 
  FROM TimeSheetWeeks
  GROUP BY TimeSheetID
  )  tsw ON ts.TimeSheetID = tsw.TimeSheetID INNER JOIN (
  SELECT  SUM(amount) amount, TimeSheetID
  FROM CompAllow
  GROUP BY TimeSheetID
  )  ca ON ts.TimeSheetID = ca.TimeSheetID INNER JOIN (
     SELECT  timeFrom, timeTo, TimeSheetID
  FROM TimeSheetWeeks
  ) AS tss ON tss.TimeSheetID=ts.TimeSheetID
  WHERE ts.TimeSheetID=6
  <b>Group By tsw.[TimeSheetID], [EmployeeID], [FromDate], [ToDate], tsw.[Amount]</b>
  )
  SELECT tot, tid, eid, fd, td, Amount = am,  totalHrs = RTRIM(mw/60) + ':' + 
  RIGHT('0'+ RTRIM(mw%60),2)
  FROM w;

将其添加到 GROUP BY 或像这样更改 Total 表达式:

Total = tsw.amount + SUM(ca.amount)

取决于此查询的业务规则是什么。
