Question

感谢Quassnoi之前谁给了我正在寻找的答案 - 这导致了一个单独的问题。目前的代码：

SELECT     i.CONCOM, COALESCE (SUM(t.LOGMINS), 0) AS TotalWithoutNew
FROM         INQUIRY AS i INNER JOIN
                  TIMELOG AS t ON t.INQUIRY_ID = i.INQUIRY_ID INNER JOIN
                  PROD AS P ON i.PROD_ID = P.PROD_ID INNER JOIN
                  CATEGORY AS C ON P.CATEGORY_ID = C.CATEGORY_ID
WHERE     (DATEPART(month, i.ESCDATE) = DATEPART(month, GETDATE()) - 1) AND (DATEPART(year,   i.ESCDATE) = DATEPART(year, DATEADD(m, - 1, GETDATE()))) AND 
                  (C.CATEGORY_ID <> '30')
GROUP BY i.CONCOM
ORDER BY TotalWithoutNew DESC

这确切地说明了我想要的内容（C.CATEGORY_ID＆lt;＆gt; 30）未包含在标记为TotalWithoutNew的初始列中。我也需要值WITH WITH。有没有办法让另一个名为TotalWithNew的列包含所有CATEGORY_ID？我肯定今天学习了很多新的查询语言！

Answer 1

SELECT     i.CONCOM, 
COALESCE (SUM(CASE WHEN C.CATEGORY_ID = '30' THEN 0 ELSE t.LOGMINS END), 0) AS TotalAllID,
COALESCE (SUM(t.LOGMINS), 0) AS TotalWithoutNew
FROM         INQUIRY AS i INNER JOIN
                  TIMELOG AS t ON t.INQUIRY_ID = i.INQUIRY_ID INNER JOIN
                  PROD AS P ON i.PROD_ID = P.PROD_ID INNER JOIN
                  CATEGORY AS C ON P.CATEGORY_ID = C.CATEGORY_ID
WHERE     (DATEPART(month, i.ESCDATE) = DATEPART(month, GETDATE()) - 1) AND (DATEPART(year,   i.ESCDATE) = DATEPART(year, DATEADD(m, - 1, GETDATE()))) 
GROUP BY i.CONCOM
ORDER BY TotalWithoutNew DESC

注意：我没有尝试，但我希望您能够使用CASE WHEN ...。

Answer 2

SELECT i.CONCOM
    , COALESCE(SUM(CASE WHEN C.CATEGORY_ID <> 30 THEN t.LOGMINS END), 0)
         AS TotalWithoutNew
    , COALESCE(SUM(t.LOGMINS), 0) AS TotalWithNew
FROM INQUIRY AS i INNER JOIN
    TIMELOG AS t ON t.INQUIRY_ID = i.INQUIRY_ID INNER JOIN
    PROD AS P ON i.PROD_ID = P.PROD_ID INNER JOIN
    CATEGORY AS C ON P.CATEGORY_ID = C.CATEGORY_ID
WHERE (DATEPART(month, i.ESCDATE) = DATEPART(month, GETDATE()) - 1)
AND (DATEPART(year,   i.ESCDATE) = DATEPART(year, DATEADD(m, - 1, GETDATE())))
GROUP BY i.CONCOM
ORDER BY TotalWithoutNew DESC
