Question

我在SQL Server中有以下数据。我想在COMPONENT 1，COMPONENT 2，COMPONENT 3，COMPONENT 4列中转置值，并将JUL，AUG，SEPT，OCT，NOV，DEC中的数字相加，如果有任何重复。我通常在Excel中使用PIVOT表但我想在SQL Server中这样做以节省一些时间。

CUST NAME   CUST PART#  PN#         COMPONENT 1 COMPONENET 2 COMPONENT 3 COMPONENT 4  JUL     AUG   SEP     OCT   NOV    DEC

COMPANY X   4455621    78601076R        902031    1200959           1                                              2

COMPANY X   4455439    78601018R        900574    1200960           2                                                    12
COMPANY X   4455438   78601018L         900574    1200960           2                                                    12
COMPANY X   4455364   78601016R         900574    1200959                                                      6    6   
COMPANY X   4455361   78601016L         900574    1200959                                                      6    6   
COMPANY X   4455363   78601014R         900574    1200958                                                      6    6   
COMPANY X   4455362   78601014L         900574    1200958                                                      6    6

我想得到以下结果

CUST NAME   COMP    JUL AUG    SEPT OCT   NOV DEC
---------------------------------------------------
COMPANY X   1200958  2               12   16    
COMPANY X   1200959  2               12   16    
COMPANY X   1200960  4                         24

Answer 1

根据您的示例输出，您似乎不会转置任何内容，而只是简单地聚合“COMPONENET 2”。

查询：

SELECT CUST, NAME,   COMP2,
    SUM( JUL ) AS Jul, SUM( AUG ) AS AUG, SUM( SEPT ) AS SEPT,
    SUM( OCT ) AS OCT, SUM( NOV ) AS AUG, SUM( DEC ) AS DEC
FROM [table]
GROUP BY CUST, NAME,   COMP2

如何在SQL Server中进行转置和求和？
