SSRS排序列

Question

我有一些数据，看起来像这样

ID |Name | Label1| Data1 |L2 |D2 |L3 | D3| 
AAAA | C | X  | 2  | Y | 4 | | | 
BBBB | D | Y  | 5  | Z | 6 | | | 
CCCC | E | X  | 3  | Y | 6 | Z | 9 | 
DDDD | F | Z  | 5  | X | 6 | Y | 3 | 

，我需要像这样显示它在一份报告：

ID |Name | X | Y | Z | 
AAAA | C | 2 | 4 | 0 | 
BBBB | D | 0 | 5 | 6 | 
CCCC | E | 3 | 6 | 9 | 
DDDD | F | 6 | 3 | 5 | 

我如何去这样做呢？

你可以在SQL透视数据：

-- load test data 
declare @YourTable table(ID char(4),Name char(1),L1 char(1),D1 int,L2 char(1),D2 int,L3 char(1),D3 int) 
insert into @YourTable values 
    ('AAAA','C','X',2,'Y',4,null,null), 
    ('BBBB','D','Y',5,'Z',6,null,null), 
    ('CCCC','E','X',3,'Y',6,'Z',9), 
    ('DDDD','F','Z',5,'X',6,'Y',3) 

-- return pivoted data 
select 
    ID, 
    Name, 
    isnull([X],0) [X], 
    isnull([Y],0) [Y], 
    isnull([Z],0) [Z] 
from (
     select 
      yt.ID, 
      yt.Name, 
      ld.Label, 
      ld.Data 
     from @YourTable yt 
      cross apply (
         select L1 Label,D1 Data union all 
         select L2 Label,D2 Data union all 
         select L3 Label,D3 Data 
         ) ld 
     ) t 
    pivot (
      max(Data) 
      for Label in([X],[Y],[Z]) 
      ) p
