需要帮助将第3个表连接到Stored Proc

Question

我有一个存储过程可以很好地将两个表连接在一起。我需要从原始SP中未包含的新表中添加新字段。我要做的是为每个记录从新表中求一个字段，该记录是原始SP中父表的子记录。 我在测试查询中根据父表测试了Sum，它工作正常：

select totaldollars from TTS_EmpTime where emptimedaytotal_id='32878'

所以接下来的步骤就是整合到SP中。我这样做了，并将SP的新部分设置为粗体，以便您可以看到添加的内容。如果删除粗体部分，SP工作正常，如果不是我收到此错误：

---

*消息8120，级别16，状态1，过程TTS_RptTest2，第11行

列'TTS_EmpTimeDayTotal.EmployeeID'在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句*中。

这是我的存储过程：

    USE [TTSTimeClock]
GO
/****** Object:  StoredProcedure [dbo].[TTS_RptTest2]    Script Date: 03/04/2011 12:29:59 ******/

    -- Optional all employees or just one       
    AND (( @EmployeeID is Null) or (DayTotal.EmployeeID = @EmployeeID)) 
    order by Empdata.employeetypeid,DayTotal.punchdate

我根本没有分组，所以这必须是由别的东西引起的？ 任何帮助将不胜感激

Answer 1

这是SQL Server吗？看起来像。您使用的是SUM聚合函数，我认为您不能使用而不使用 GROUP BY子句。你是否总是在那里有SUM，或者你是否将它与新表一起添加？

如果是后者，这可能是你的问题。

哇，这可能是一种痛苦   像groupby field1，field2一样，   等等？就像在昏迷中划定的那样   名单。还有其他方法可以包含   这个领域会更好吗？

是的，在SQL Server中，使用聚合函数时必须明确分组。在您的情况下，一种替代方法是将分组作为子查询进行分组，并加入 ，即：

FROM TTS_EmpTimeDayTotal AS DayTotal 
INNER JOIN TTS_PayrollEmployees AS EmpData ON DayTotal.EmployeeID = EmpData.EmployeeID
INNER JOIN (SELECT EmpTimeDayTotal_id, SUM(CAST(TotalDollars AS FLOAT)) AS TotalDayDollars
            FROM TTS_Emptime
            GROUP BY EmpTimeDayTotal_id) AS EmpTime ON DayTotal.id = EmpTime.EmpTimeDayTotal_id

然后只需在SELECT列表中引用EmpTime.TotalDayDollars，而不是在那里执行SUM。
