SQL Server Rows to Multi-Columns - sql

Question

I have the following table and data:
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');
A simple select will return
Code | Total | Date
'AA' | 100 | 2012-12-01
'AA' | 200 | 2013-02-01
'BB' | 50 | 2012-01-01
but what I need is the following
Code | Total | Date | Total | Date
'AA | 200 | 2013-02-01 | 100 | 2012-12-01
'BB | 50 | 2012-01-01 | null | null
I have been trying to do this using a PIVOT operator but without success (based on the question SQL Server Pivot multiple columns based on one column).
Using that example, all I get are two rows with null values.
The Total/Date columns can be repeated 13 times and they must be ordered by Date DESC.

Any help is appreciated!
Thanks!

Answer 1

If you need just two columns:
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
=> sql fiddle demo
dynamic solution:
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

Are you trying to dynamically create columns in your result set?
If you had a third record of 'AA' with a total of 300 and the date of 03/01/2013 would you that mean you would want something like this displayed?
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
