如何将SQL Server行转换为多列？

Question

如何将SQL Server数据行转换为多列？我有以下数据

 [STOCK NO]  [PN1]   [PN2]    [PN3]   [PN4]       [PN4]   [PN5]   [PN6]  [PN7]  [PN8]     [PN9] [PN10] [PN11] [PN12] [Qty] 
    700349L   600446   201743   100208          300219   400533     100280  100218     100222   100220 100221  1 

类似节目我希望看到这样的事情

[STOCK NO]  [bomRev]  [bomEntry] [partId] [qty] [cmnt] [srcLoc] [dType] [lead] [lineNbr] 
700349L    A    1   600446 1  `TEST` TEST  0   0  1 
700349L    A    2   201743 1  `TEST` TEST  0   0  2 
700349L    A    3   100208 1  `TEST` TEST  0   0  3 
700349L    A    4   300219 1  `TEST` TEST  0   0  4 

700349L    A    5   400533 1  `TEST` TEST  0   0  5 

700349L    A    6   100218 1  `TEST` TEST  0   0  6 
700349L    A    7   100222 1  `TEST` TEST  0   0  7 
700349L    A    8   100220 1  `TEST` TEST  0   0  8 
700349L    A    9   100221 1  `TEST` TEST  0   0  9 

然后我想使用select语句插入如下图所示，但我想调换行多列

INSERT INTO [DT]([bomItem], [bomRev], [bomEntry], [partId], [qty], [cmnt],[srcLoc], [dType], [lead], [lineNbr]) 
    SELECT 
     [STOCK NO], 'A', [bomEntry], [partid], [qty], 'TEST', 'TEST', '0', '0', [lineNbr] 
    FROM 
     [ST] 

Answer 1

这使用问题中的其他编辑之前的列和示例数据。

使用cross apply()到unpivot的栏位，并row_number()至数只具有一个值的那些行：

--INSERT INTO [DT]([bomItem], [bomRev], [bomEntry], [partId], [qty], [cmnt],[srcLoc], [dType], [lead], [lineNbr]) 
select 
    st.[CALC STOCK NO]  
    , bomRev = 'A' 
    , bomEntry = row_number() over (order by u.ordinal) 
    , u.Partid 
    , st.Qty 
    , cmnt = 'Test' 
    , srcLoc = 'Test' 
    , dType = '0' 
    , lead = '0' 
    , lineNbr = row_number() over (order by u.ordinal) 
from st 
    cross apply (values 
    (1,[BOM WHEEL PN]) 
    ,(2,[BOM TIRE PN]) 
    ,(3,[BOM VALVE PN]) 
    ,(4,[BOM - SECONDARY DISC PN]) 
    ,(5,[BOM - DISC]) 
    ,(6,[BOM - RIM]) 
    ,(7,[BUY WHEEL]) 
    ,(8,[COLOR PN]) 
    ,(9,[WHL BOM PART 1 PN]) 
    ,(10,[WHL BOM PART 2 PN]) 
    ,(11,[WHL BOM PART 3 PN]) 
    ,(12,[WHL BOM PART 4 PN]) 
    ,(13,[WHL BOM PART 5 PN]) 
) u (ordinal, partId) 
where nullif(u.partId,'') is not null

透视SH应该为你工作。
