Sql server 2005 CTE连接查询问题

这个问题现在让我头晕目眩，我想知道是否有人能给我指点一下我哪里出了问题

我正在尝试生成一个存储过程，该存储过程生成一个数据集，供SSRS调用，用于过去6个月的图形

例如，数据使用三个表（还有更多，但不会改变手头的问题），如下所示：

DECLARE @ReportName VarChar(200)
SET @ReportName = 'North';

WITH TicketsRaisedThisMonth AS
(
    SELECT
            [Date],
            Site,
            SUM(NoOfTickets) AS NoOfTickets
    FROM    tbl_TicketsRaisedThisMonth
    WHERE [Date] >= DATEADD(mm, DATEDIFF(m,0,GETDATE())-6,0)
    GROUP BY [Date], Site
),

FeedBackRequests AS
(
    SELECT
            [Date],
            Site,
            SUM(NoOfFeedBackR) AS NoOfFeedBackR
    FROM    tbl_FeedBackRequests
    WHERE [Date] >= DATEADD(mm, DATEDIFF(m,0,GETDATE())-6,0)
    GROUP BY [Date], Site
),

SELECT
    trtm.[Date]
    SUM(trtm.NoOfTickets) AS NoOfTickets,
    SUM(fbr.NoOfFeedBackR) AS NoOfFeedBackR,

FROM tbl_ReportList rpts

LEFT OUTER JOIN TotalIncidentsDuringMonth trtm ON rpts.Site = trtm.Site
LEFT OUTER JOIN LoggedComplaints fbr ON rpts.Site = fbr.Site

WHERE rpts.report = @ReportName
GROUP BY trtm.[Date]

Date                       NoOfTickets             NoOfFeedBackR

我使用CTE简化代码，如下所示：

DECLARE @ReportName VarChar(200)
SET @ReportName = 'North';

WITH TicketsRaisedThisMonth AS
(
    SELECT
            [Date],
            Site,
            SUM(NoOfTickets) AS NoOfTickets
    FROM    tbl_TicketsRaisedThisMonth
    WHERE [Date] >= DATEADD(mm, DATEDIFF(m,0,GETDATE())-6,0)
    GROUP BY [Date], Site
),

FeedBackRequests AS
(
    SELECT
            [Date],
            Site,
            SUM(NoOfFeedBackR) AS NoOfFeedBackR
    FROM    tbl_FeedBackRequests
    WHERE [Date] >= DATEADD(mm, DATEDIFF(m,0,GETDATE())-6,0)
    GROUP BY [Date], Site
),

SELECT
    trtm.[Date]
    SUM(trtm.NoOfTickets) AS NoOfTickets,
    SUM(fbr.NoOfFeedBackR) AS NoOfFeedBackR,

FROM tbl_ReportList rpts

LEFT OUTER JOIN TotalIncidentsDuringMonth trtm ON rpts.Site = trtm.Site
LEFT OUTER JOIN LoggedComplaints fbr ON rpts.Site = fbr.Site

WHERE rpts.report = @ReportName
GROUP BY trtm.[Date]

Date                       NoOfTickets             NoOfFeedBackR
-----------------------------------------------------------------------------------
2010-07-01 00:00:00.000             128                              112
2010-08-01 00:00:00.000     <data for that month>       <data for that month>
2010-09-01 00:00:00.000     <data for that month>       <data for that month>
2010-10-01 00:00:00.000     <data for that month>       <data for that month>
2010-11-01 00:00:00.000     <data for that month>       <data for that month>

存储过程启动时的输出将传递一个参数，如“North”，如下所示：

DECLARE @ReportName VarChar(200)
SET @ReportName = 'North';

WITH TicketsRaisedThisMonth AS
(
    SELECT
            [Date],
            Site,
            SUM(NoOfTickets) AS NoOfTickets
    FROM    tbl_TicketsRaisedThisMonth
    WHERE [Date] >= DATEADD(mm, DATEDIFF(m,0,GETDATE())-6,0)
    GROUP BY [Date], Site
),

FeedBackRequests AS
(
    SELECT
            [Date],
            Site,
            SUM(NoOfFeedBackR) AS NoOfFeedBackR
    FROM    tbl_FeedBackRequests
    WHERE [Date] >= DATEADD(mm, DATEDIFF(m,0,GETDATE())-6,0)
    GROUP BY [Date], Site
),

SELECT
    trtm.[Date]
    SUM(trtm.NoOfTickets) AS NoOfTickets,
    SUM(fbr.NoOfFeedBackR) AS NoOfFeedBackR,

FROM tbl_ReportList rpts

LEFT OUTER JOIN TotalIncidentsDuringMonth trtm ON rpts.Site = trtm.Site
LEFT OUTER JOIN LoggedComplaints fbr ON rpts.Site = fbr.Site

WHERE rpts.report = @ReportName
GROUP BY trtm.[Date]

Date                       NoOfTickets             NoOfFeedBackR

我遇到的问题是，当我执行查询时，会给我一个每月重复的值列表，例如128将重复6次，然后下个月的另一个值将重复6次，等等。argh

您需要改变返回月份的方式。在结果集中，您将返回trtm.[Date]，但要左键连接到trtm，因此此可能不存在。
如果它始终存在，则将其转换为内部联接，并将另一个左联接更改为包含从trtm.[Date]到fbr.[Date]的链接。

---

否则，您需要一个“月”表来返回月列表，并在日期字段中将其与trtm和fbr（以及站点上的现有联接）保持联接。

您的表定义与您的查询不匹配-查询中引用了什么

？这是tbl_报告列表吗？谢谢你指出，更正了。
