Question

我想让[LA，LI，LS，LU，LX，LY] = LUFT以及[XY，MN，ST] = BASE 请参阅下文以了解更多信息这是我的疑问：

SELECT 
[ABC] = 'LUFT',
ROUND(SUM([GWU VS]),1) AS [GWU LUFT],
[ABC] = 'BASE',
ROUND(SUM([GWU VS]),1) AS [GWU BASE]
FROM tbl1
WHERE [ABC]='LA' OR [ABC]='LI' OR [ABC]='LS' 
OR [ABC]='LU' OR [ABC]='LX' OR [ABC]='LY' 
AND
[ABC]='XY' OR [ABC]='MN' OR [ABC]='ST'
--GROUP BY [ABC]
--ORDER BY [ABC] ASC

我的表：

ABC    GWU VS
LA      100
LI      80
LS      50
LU      200
LX      220
LY      150
XY      450
MN      600
ST      85

但我得到了错误的结果我真正希望得到的结果是：

ABC      GWU VS
LUFT      800
BASE      1135

Answer 1

case是最明显的答案：

sum(case when [ABC] in ('LA', 'LI', ...) then [GWU VS] else 0 end) AS [GWU LUFT],

Answer 2

这将按照您的要求提供结果：

SELECT 
    'LUFT' as [ABC],
    ROUND(SUM([GWU VS]),1) AS [GWU VS]
FROM tbl1
WHERE ([ABC] IN ('LA','LI','LS','LU','LX','LY'))
UNION
SELECT 
    'BASE' as [ABC],
    ROUND(SUM([GWU VS]),1) AS [GWU VS]
FROM tbl1
WHERE ([ABC] IN ('LA','LI','LS'))

Answer 3

使用Case语句将ABC列分为两组，然后应用group by。试试这个。

SELECT ABC=CASE
            WHEN abc IN ( 'LA', 'LI', 'LS', 'LU','LX', 'LY' ) THEN 'LUFT'
            ELSE 'BASE'
           END,
       [GWU VS]=Sum([GWU VS])
FROM   Yourtable
GROUP  BY CASE
            WHEN abc IN ( 'LA', 'LI', 'LS', 'LU','LX', 'LY' ) THEN 'LUFT'
            ELSE 'BASE'
          END
