Hi,
I have a table which looks likes this when you use a select Statement:

1 2 3 4
CCAS ASPT2 200 2011/01
CCAS ASPT2 200 2011/02
CCAS ASPT2 100 2011/03
CCAS CODI 10 2011/01
CCAS CODI 10 2011/03
DEL DIAI2 25 2011/01
DEL DIAI2 10 2011/02
DEL DIAI2 35 2011/03
DEL DIAI3 20 2011/01
DEL DIAI3 35 2011/02

I would like to be able to manipulate the table(using T-SQL) so that the final outut looks likes this:

2011/01 2011/02 2011/03
1 2 3 3 3
CCAS ASPT2 200 200 100
CCAS CODI 10 0 10
DEL DIAI2 25 10 35
DEL DIAI3 20 35 0

That is to tranpose some columns to rows with the corresponding values in each row.
That is to have the YYYY/MM as column headdings with the correspong values from the first three rows written as one row.
I hope this is clear!

Any idea how to do this?

Best regards,

Fortran77

Hi,
This should read like this;
CCAS ASPT2 200 2011/01
CCAS ASPT2 200 2011/02
CCAS ASPT2 100 2011/03
CCAS CODI 10 2011/01
CCAS CODI 10 2011/03
DEL DIAI2 25 2011/01
DEL DIAI2 10 2011/02
DEL DIAI2 35 2011/03
DEL DIAI3 20 2011/01
DEL DIAI3 35 2011/02

will tranlate to:

2011/01 2011/02 2011/03
CCAS ASPT2 200 200 100
CCAS CODI 10 0 10
DEL DIAI2 25 10 35
DEL DIAI3 20 35 0

I hope this clear now.

2011/01, 2011/02, 2011/03 are the column headings for 200, 200, 100 in the second list!

use something like

SELECT [1],[2],
MAX(CASE WHEN [4] = '2011/01' THEN [3] END) AS [2011/01],
MAX(CASE WHEN [4] = '2011/02' THEN [3] END) AS [2011/02],
MAX(CASE WHEN [4] = '2011/03' THEN [3] END) AS [2011/03]
FROM table
GROUP BY [1],[2]
