Question

我有以下代码，它将结果显示在包含多个列的表中。

SELECT 
   ref, design, 
   ISNULL((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 34 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'LPP', 
   ISNULL((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 28 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'LPM', 
   ISNULL((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 42 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RNPM', 
   ISNULL((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 68 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RAM', 
   ISNULL((SELECT Sum(qtt2) FROM bi(nolock) WHERE  bi.ndos = 68 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RA' ,
   ISNULL((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 59 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'GD'
FROM   
    bi(nolock) temp
WHERE  
    (temp.ndos = 34 OR temp.ndos = 28  OR temp.ndos = 42  OR temp.ndos = 68) 
    AND temp.bofref LIKE #1# 
    AND temp.ref NOT LIKE ' ' 
GROUP BY 
    ref, design 
ORDER BY 
    ref

我现在想要在新列中对某些select的值求和，例如我想对列进行求和＆＃34; LPP，RNPM和RA＆＃34;在整个专栏中，但我无法让它发挥作用。

怎么做？

Answer 1

最直接的方法是将您的查询包装在另一个中：

SELECT sub.*,
       LPP + RNPM + RA as LPP_RNPM_RA
FROM (       
    SELECT ref, design, 
       Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 34 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'LPP', 
       Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 28 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'LPM', 
       Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 42 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RNPM', 
       Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 68 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RAM', 
       Isnull((SELECT Sum(qtt2) FROM bi(nolock) WHERE  bi.ndos = 68 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RA' ,
       Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 59 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'GD'
    FROM   bi(nolock) temp
    WHERE  temp.ndos IN (34, 28, 42, 68) 
       AND temp.bofref like #1# 
       AND temp.ref NOT LIKE ' ' 
    GROUP  BY ref, 
          design 
    ) as sub
ORDER  BY ref

请注意，您可以使用IN运算符代替OR子句中的where运算符。

此外，你总结的方式看起来很尴尬：不要做子查询，但是在你的select中执行此操作：

       Sum(CASE WHEN temp.ndos = 34 THEN qtt ELSE 0 END) AS 'LPP',

......等等。

如果我理解正确，你可以总结单列

  SELECT 
          ref
        , design
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 34 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'LPP', 
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 28 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'LPM', 
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 42 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RNPM', 
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 68 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RAM', 
     Isnull((SELECT Sum(qtt2) FROM bi(nolock) WHERE  bi.ndos = 68 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'RA' ,
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 59 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) AS 'GD',  
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 34 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) + 
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 28 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) + 
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 42 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) + 
     Isnull((SELECT Sum(qtt) FROM bi(nolock) WHERE  bi.ndos = 68 AND bofref like #1# AND bi.ref = temp.ref GROUP  BY ref), 0) as TOTAL_COLUMN 

  FROM   bi(nolock) temp
  WHERE  ( temp.ndos = 34
        OR temp.ndos = 28 
        OR temp.ndos = 42 
        OR temp.ndos = 68 ) 
     AND temp.bofref like #1# 
     AND temp.ref NOT LIKE ' ' 
  GROUP  BY ref, 
        design 
  ORDER  BY ref
