Question

我有以下SQL Server 2008 TABLE：

Heading     Limit   Package
X Charges   200     A
X Charges   300     B
X Charges   400     C
X Charges   500     D
Y Charges   550     A
Y Charges   450     B
Y Charges   350     C
Y Charges   250     D

现在我希望以下列表示获取数据：

Heading    Package_A   Package_B  Package_C  Package_D
X Charges  200         300        400        500
Y Charges  550         450        350        250

Answer 1

请尝试：

SELECT
  Heading, 
  A Package_A,
  B Package_B,
  C Package_C,
  D Package_D
FROM (
      SELECT * FROM YourTable
) up 
PIVOT (sum(Limit) FOR Package IN (A, B, C, D)) AS pvt

Answer 3

请更新下表中的表名：

declare
    @cols nvarchar(max),
    @stmt nvarchar(max)

select @cols = isnull(@cols + ', ', '') + '[' + T.Package+ ']' 
     from (select distinct Package from TABLE1) as T

select @stmt = '
    select *
    from TABLE1 as T
        pivot 
        (
            max(T.VALUE)
            for T.Package in (' + @cols + ')
        ) as P'

exec sp_executesql  @stmt = @stmt

Answer 4

Declare @t table( Heading varchar(50), Limit int,Package varchar(20)) 
insert into @t
select    'X Charges',   200,'A' union all
select  'X Charges',   300,'B' union all
select  'X Charges',   400,'C' union all
select  'X Charges',   500,'D' union all
select  'Y Charges',   550,'A' union all
select  'Y Charges',   450,'B' union all
select  'Y Charges',   350,'C' union all
select  'Y Charges',   250,'D'

select * from
(select * from @t)t4
pivot (min(limit) for Package in([A],[B],[C],[D]))pvt

Answer 5

为了动态执行此操作：

Declare
@cols varchar(max)
select @cols =  stuff(
 (select distinct ',' + quotename(package)
from data
for xml path (''), type
).value('.', 'varchar(max)'), 1,1, '')  

declare 
@query varchar(max)

set @query = 'select distinct heading, ' + @cols + ' from
        (
            select   heading, Limit, Package
            from    data

        ) X
        pivot
        (
              MAX(Limit)
              for   Package in ('+@cols + ')
        ) p'

exec(@query)
