将列值转换为行

Question

我想将单列值转换为行。

表原件内容：

Code  Amount   Expenditure 
10027 5000.00 LOCAL CONVEYANCE 
10027  320.00 LOCAL CONVEYANCE 
10116 1589.00 TRAVEL EXPENSES 
10095  350.00 LOCAL CONVEYANCE 
10095 1215.00 TRAVEL EXPENSES 

预期输出：

Code LC TE 
10027 5000.00 NULL 
10027 320.00 NULL 
10116 NULL 1589.00 
10095 350.00 1215.00 

Answer 1

;WITH PvtSource AS 
(
SELECT Code, 
     Amount, 
     Expenditure, 
     ROW_NUMBER() OVER (PARTITION BY Code,Expenditure 
           ORDER BY Code) AS RN 
FROM YourTable 
) 
SELECT Code, 
     [LOCAL CONVEYANCE] AS LC, 
     [TRAVEL EXPENSES] AS TE 
FROM PvtSource 
PIVOT (MAX(Amount) FOR Expenditure IN ([LOCAL CONVEYANCE],[TRAVEL EXPENSES])) P 
ORDER BY Code

这里是如何做到这一点的完整示例。关于我在你的问题中提出的评论有一个问题。

create table #original (
Code int, 
Amount float, 
Expenditure varchar(20) 
) 

create table #output (
Code int, 
LC float, 
TE float 
) 

insert into #original values (10027, 5000, 'LOCAL CONVEYANCE') 
insert into #original values (10027, 320, 'LOCAL CONVEYANCE') 
insert into #original values (10116, 1589, 'TRAVEL EXPENSES') 
insert into #original values (10095, 350, 'LOCAL CONVEYANCE') 
insert into #original values (10095, 1215, 'TRAVEL EXPENSES') 



insert into #output 
select o.Code, o.Amount, NULL 
from #original o 
where o.Expenditure = 'LOCAL CONVEYANCE' 

insert into #output 
select o.Code, NULL, o.Amount 
from #original o 
where o.Expenditure = 'TRAVEL EXPENSES' 
and o.Code not in (select Code from #output) 

update #output 
set TE = o.Amount 
from #output p 
inner join #original o on o.Code = p.Code and o.Expenditure = 'TRAVEL EXPENSES' 




select * from #output 

drop table #original 
drop table #output
