在TSQL

Question

樞行列我有以下表下面的示例數據

ID Language  Question  SubQuestion  SubSubQuestion TotalCount TotalPercent 
3  E    9    0    1    88527   73% 
3  E    9    0    2    19684   16% 
3  E    9    0    3    12960   11% 
3  E    9    0    9    933    1% 

我希望所有在一排這樣的

ID Language  TotalCount901 TotalPercent901  TotalCount902 TotalPercent902 TotalCount903 TotalPercent903 
    3  E   88527   73%     19684    16%    12960    11% 

我已經厭倦了使用轉動命令時，但它爲我工作。

我根據你的列名作了一些假設，但看起來你想用類似的東西。這不僅適用於一個UNPIVOT，然後PIVOT得到你要求的列中的值：

select * 
from 
(
    select id, 
    language, 
    col + cast(QUESTION as varchar(10)) 
     +cast(subquestion as varchar(10)) 
     +cast(SubSubQuestion as varchar(10)) col, 
    value 
    from 
    (
    select id, language, 
     cast(TotalCount as varchar(10)) TotalCount, 
     totalPercent, 
     question, subquestion, SubSubQuestion 
    from yourtable 
) usrc 
    unpivot 
    (
    value 
    for col in (totalcount, totalpercent) 
) un 
) srcpiv 
pivot 
(
    max(value) 
    for col in ([TotalCount901], [totalPercent901], 
       [TotalCount902], [totalPercent902], 
       [TotalCount903], [totalPercent903], 
       [TotalCount909], [totalPercent909]) 
) p

注：在執行UNPIVOT時，列必須是相同的數據類型的。如果它們不是，那麼你將需要轉換/轉換以獲得相同的數據類型。

如果你有一個未知的數值進行改造，就可以使用動態SQL：

DECLARE @query AS NVARCHAR(MAX), 
    @colsPivot as NVARCHAR(MAX) 


select @colsPivot 
    = STUFF((SELECT ',' 
      + QUOTENAME(c.name + 
         cast(QUESTION as varchar(10)) 
         +cast(subquestion as varchar(10)) 
         +cast(SubSubQuestion as varchar(10))) 
      from yourtable t 
      cross apply sys.columns as C 
      where C.object_id = object_id('yourtable') and 
       C.name in ('TotalCount', 'TotalPercent') 
      group by c.name, t.question, t.subquestion, t.subsubquestion 
      order by t.SubSubQuestion 
      FOR XML PATH(''), TYPE 
      ).value('.', 'NVARCHAR(MAX)') 
     ,1,1,'') 


set @query = 'select * 
       from 
       (
       select id, 
        language, 
        col + cast(QUESTION as varchar(10)) 
        +cast(subquestion as varchar(10)) 
        +cast(SubSubQuestion as varchar(10)) col, 
        value 
       from 
       (
        select id, language, 
        cast(TotalCount as varchar(10)) TotalCount, 
        totalPercent, 
        question, subquestion, SubSubQuestion 
        from yourtable 
       ) usrc 
       unpivot 
       (
        value 
        for col in (totalcount, totalpercent) 
       ) un 
      ) srcpiv 
      pivot 
      (
       max(value) 
       for col in (' + @colsPivot + ') 
      ) p ' 

execute(@query)
