Question

我想将单列值转换为Row。

表原始内容：

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

预期产出：

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

Answer 2

以下是有关如何操作的完整示例。关于我在你的问题中提出的评论存在问题。

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
