Sql 获取特定的表

我正在使用SQL server 2008，并使用以下函数构建了一个表：

    SELECT COD1 + COD2 + COD3 AS CODFINAL,
           SUM(CASE WHEN SIG1  =  'BCO' THEN 1 ELSE 0 END) AS A1,
           SUM(CASE WHEN SIG1   = 'RIP' THEN 1 ELSE 0 END) AS B1,
           SUM(CASE WHEN SIG1   = 'MIN' THEN 1 ELSE 0 END) AS B1,
           SUM(CASE WHEN SIG1   = 'MAD' THEN 1 ELSE 0 END) AS B1,
           SUM(CASE WHEN SIG1   = 'CPR' THEN 1 ELSE 0 END) AS PC1,
           SUM(CASE WHEN SIG1   = 'MAR' THEN 1 ELSE 0 END) AS B1,
           SUM(CASE WHEN SIG1   = 'LAC' THEN 1 ELSE 0 END) AS CLu
FROM DBO.DATABASE 

我得到了这样的结果：

CODFINAL   A1   B1  B1    B1   PC1   B1   CLu 
B12030     1    1   1      1     1    2    3
C12130     1    1   1      1     1    2    3
D12230     1    1   1      1     1    2    3
E12230     1    1   1      1     1    2    3

CODFINAL   A1   B1  PC1  CLu    
B12030     1    5    1    3
C12130     1    5    1    3
D12230     1    5    1    3
E12230     1    5    1    3

但我希望有一个具有唯一总值的表，如下所示：

CODFINAL   A1   B1  B1    B1   PC1   B1   CLu 
B12030     1    1   1      1     1    2    3
C12130     1    1   1      1     1    2    3
D12230     1    1   1      1     1    2    3
E12230     1    1   1      1     1    2    3

CODFINAL   A1   B1  PC1  CLu    
B12030     1    5    1    3
C12130     1    5    1    3
D12230     1    5    1    3
E12230     1    5    1    3

您可以使用：

可能是这样的吗

WITH MyCodes
(
SELECT COD1 + COD2 + COD3 AS CODFINAL,
           SUM(CASE WHEN SIG1  =  'BCO' THEN 1 ELSE 0 END) AS A1,
           SUM(CASE WHEN SIG1   = 'RIP' THEN 1 ELSE 0 END) AS B1a,
           SUM(CASE WHEN SIG1   = 'MIN' THEN 1 ELSE 0 END) AS B1b,
           SUM(CASE WHEN SIG1   = 'MAD' THEN 1 ELSE 0 END) AS B1c,
           SUM(CASE WHEN SIG1   = 'CPR' THEN 1 ELSE 0 END) AS PC1,
           SUM(CASE WHEN SIG1   = 'MAR' THEN 1 ELSE 0 END) AS B1d,
           SUM(CASE WHEN SIG1   = 'LAC' THEN 1 ELSE 0 END) AS CLu
FROM DBO.DATABASE 
)
SELECT CODFINAL,A1,B1a+B1b+B1c+B1d AS B1, PC1,CLu FROM MyCodes

那么您希望将行连接成单个字符串？为什么有这么多名为

B1

的列？如果您想在case语句中包含多个值，可以将其重写为B1，就像

SUM一样（当SIG1在（'RIP'、'MIN'、'MAD'、'MAR'）中时，则将其重写为B1
