Question

我知道之前已经有人问过这个问题，但是我遇到了麻烦。我有2个查询。一个返回评级为10％的报价之和，另一个返回评级为20％的报价之和。但是，我试图返回两个值的总和。到目前为止，我的查询是：

SELECT SUM(total) FROM (

SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.10) AS "10%" 
FROM ((dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID) LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID)    WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  1 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''

UNION ALL

SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.20) AS "20%" 
FROM ((dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID) LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID)    WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  2 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''
)a

但是显然我在FROM附近有不正确的语法。

有什么想法吗？

Answer 1

使用UNION ALL的正确语法是

SELECT *
FROM
(
     SELECT col1, col2 FROM TABLE1
     UNION ALL
     SELECT col1, col2 FROM TABLE2
) AS alias

您发布的查询对我来说没有意义，因此不确定如何更正

您的2条查询看起来非常相似，只是UQMLSALESSTAGE有所不同。可能这就是您想要的。而且您不需要使用union

SELECT  SUM(dbo.QuoteLines.UQMLQUOTEVALUE * 
            CASE WHEN dbo.QuoteLines.UQMLSALESSTAGE = 1 THEN 0.10 ELSE 0.20 END) AS Total
FROM    dbo.Quotes 
        LEFT OUTER JOIN dbo.QuoteLines  ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID
        LEFT OUTER JOIN dbo.Followups   ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID
WHERE   dbo.Quotes.qmpClosed  =  0 
AND     dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  = -1 
AND     dbo.QuoteLines.UQMLSALESSTAGE       IN ( 1 , 2 )
AND     dbo.Followups.cmfStatus             <  3 
AND     dbo.QuoteLines.qmlResolutionReasonID =  ''

Answer 2

您的脚本有问题。请尝试以下脚本-

SELECT SUM(total) FROM (
    SELECT
    SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.10) AS total
    FROM dbo.Quotes 
    LEFT OUTER JOIN dbo.QuoteLines 
        ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID
    LEFT OUTER JOIN dbo.Followups 
        ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID    
    WHERE  dbo.Quotes.qmpClosed  =  0 
    AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 
    AND dbo.QuoteLines.UQMLSALESSTAGE  =  1 
    AND dbo.Followups.cmfStatus  <  3 
    AND dbo.QuoteLines.qmlResolutionReasonID  =  ''

    UNION ALL

    SELECT
    SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.20) AS total 
    FROM dbo.Quotes 
    LEFT OUTER JOIN dbo.QuoteLines 
        ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID 
    LEFT OUTER JOIN dbo.Followups 
        ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID    
    WHERE  dbo.Quotes.qmpClosed  =  0 
    AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 
    AND dbo.QuoteLines.UQMLSALESSTAGE  =  2 
    AND dbo.Followups.cmfStatus  <  3 
    AND dbo.QuoteLines.qmlResolutionReasonID  =  ''
)a

Answer 3

找不到总计字段，联接表错误

也许您可以尝试这个

SELECT SUM(total) FROM (

SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.10) total 
FROM ((select dbo.QuoteLines.UQMLQUOTEVALUE from dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID) LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID)   WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  1 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''

UNION ALL

SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.20) total
FROM ((select dbo.QuoteLines.UQMLQUOTEVALUE from dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID) LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID)    WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  2 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''
)a

Answer 4

尝试一下：

SELECT SUM(total) FROM (
select 
SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.10) AS "total" 
From dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID
LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID    WHERE  dbo.Quotes.qmpClosed  =  0 
AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  1 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''

UNION ALL
select 
SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.20) AS "total" 
FROM dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID
LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID  
WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  2 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''
)a

Answer 5

您在FROM ()a中的代码不完整。您可以尝试提取该代码并单独运行。例如：

SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.10) AS "10%" 
FROM ((dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID) LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID)    WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  1 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''

UNION ALL

SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.20) AS "20%" 
FROM ((dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID) LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID)    WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  2 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''

该代码无法单独运行，因为缺少SELECT。如果您解决了该问题，然后将代码重新插入FROM ()a，那么我认为您的状态会很好。例如：

SELECT SUM(total) FROM (
SELECT
SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.10) AS "10%" 
FROM ((dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID) LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID)    WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  1 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''

UNION ALL
SELECT
SUM(dbo.QuoteLines.UQMLQUOTEVALUE*0.20) AS "20%" 
FROM ((dbo.Quotes LEFT OUTER JOIN dbo.QuoteLines ON dbo.Quotes.qmpQuoteID = dbo.QuoteLines.qmlQuoteID) LEFT OUTER JOIN dbo.Followups ON dbo.QuoteLines.qmlQuoteID = dbo.Followups.cmfQuoteID)    WHERE  dbo.Quotes.qmpClosed  =  0 AND dbo.Quotes.UQMPFORWARDEDTOCUSTOMER  =  -1 AND dbo.QuoteLines.UQMLSALESSTAGE  =  2 AND dbo.Followups.cmfStatus  <  3 AND dbo.QuoteLines.qmlResolutionReasonID  =  ''
)a

使用将两个查询加在一起
