SQL Server行到多列

SQL Server行到多列,sql,sql-server,azure-sql-database,Sql,Sql Server,Azure Sql Database,我有以下表格和数据: CREATE TABLE SourceTbl ([Code] varchar(3), [Total] decimal, [Date] datetime ); INSERT INTO SourceTbl ([Code], [Total], [Date]) VALUES ('AA', 100, '2012-12-01'), ('AA', 200, '2013-02-01'), ('BB', 50, '2012-01-01'); 一个简单的选择将返回 Code | Tota

我有以下表格和数据:

CREATE TABLE SourceTbl ([Code] varchar(3), [Total] decimal, [Date] datetime );

INSERT INTO SourceTbl ([Code], [Total], [Date]) 
VALUES ('AA', 100, '2012-12-01'), ('AA', 200, '2013-02-01'), ('BB', 50, '2012-01-01');
一个简单的选择将返回

Code | Total | Date
'AA' | 100   | 2012-12-01
'AA' | 200   | 2013-02-01
'BB' | 50    | 2012-01-01
但我需要的是

Code | Total | Date       | Total | Date
'AA  | 200   | 2013-02-01 | 100   | 2012-12-01
'BB  | 50    | 2012-01-01 | null  | null
我一直在尝试使用PIVOT操作符来实现这一点,但没有成功(基于这个问题)

使用该示例,我得到的只是两行空值

“总计/日期”列可以重复13次,并且必须按日期说明排序

SQL Fiddle:

感谢您的帮助!
谢谢

是否尝试在结果集中动态创建列

如果您有第三条“AA”记录,总共300条,日期为2013年1月3日,您是否希望显示类似的内容

Code | Total | Date       | Total | Date      | Total | Date
 AA  | 200   | 2013-02-01 | 100   | 2012-12-01| 300   | 03-01-13
 BB  | 50    | 2012-01-01 | null  | null      | null  | null        

如果只需要两列:

with cte as (
    select *, row_number() over(partition by Code order by Date) as rn
    from SourceTbl
)
select
    code,
    max(case when rn = 1 then Total end) as Total1,
    max(case when rn = 1 then Date end) as Date1,
    max(case when rn = 2 then Total end) as Total2,
    max(case when rn = 2 then Date end) as Date2
from cte
group by code

动态解决方案:

declare @stmt nvarchar(max)

;with cte as (
     select distinct
         cast(row_number() over(partition by Code order by Date) as nvarchar(max)) as rn
     from SourceTbl
)
select @stmt = isnull(@stmt + ', ', '') + 
    'max(case when rn = ' + rn + ' then Total end) as Total' + rn + ',' +
    'max(case when rn = ' + rn + ' then Date end) as Date' + rn 
from cte
order by rn

select @stmt = '
    with cte as (
        select *, row_number() over(partition by Code order by Date) as rn
        from SourceTbl
    )
    select
        code, ' + @stmt + ' from cte group by code'

exec sp_executesql
    @stmt = @stmt

为营救提供支点
+
行号()
。这应该是一个注释而不是答案是的,我最多可以有13个总/日期组合。干得好!我从来不知道你可以动态添加这样的列。这正是我所需要的!非常感谢。
