Normalize database (unpivot month columns)

[deathseeker]

I have a Excel table connected to SQL(PERVASIVE) that outputs a column for each month.
For working it better in Excel, I need to transforme that 12 columns to only 2...
- a first one for the values;
- the second for the respective month (that at this moment, months are the column titles).


Objective: turn the current database structure:

Al_Cta | MoedCod | TpVal | FlagDC | Month01 | Month02 | Month03
AAAAA | 100 | 20 | 5| 15 | 18 | 16
BBBBB | 200 | 40 | 10| 20 | 21 | 26
CCCCC | 300 | 60 | 15| 40 | 48 | 41

The desirable output:

Al_Cta | MoedCod|TpVal | FlagDC | Value | Month
AAAAA | 100 | 20| 5 | 15 | 01
AAAAA | 100 | 20| 5 | 18 | 02
AAAAA | 100 | 20| 5 | 16 | 03
BBBBB | 200 | 40| 10 | 20 | 01
BBBBB | 200 | 40| 10 | 21 | 02
BBBBB | 200 | 40| 10 | 26 | 03
CCCCC | 300 | 60| 15 | 40 | 01
CCCCC | 300 | 60| 15 | 48 | 02
CCCCC | 300 | 60| 15 | 41 | 03




I already had some help in the forum, but I did not managed to do it.
I use the following command, but the database simply do not change at all, could someone see what is wrong?
I am inserting the following in command text, in query properties on Excel.

----------

SELECT *
FROM [IN16-CTAVAL]
Select p.Al_Cta ,MoedCod ,TpVal,FlagDC,
sale_quantity ,salemonths
From products as p
inner join (
Select Al_Cta ,sale_quantity ,salemonths from products
UNPIVOT
(
salemonths for sale_quantity in (Month01 | Month02 | Month03)
)) as pp on p.Al_Cta = pp.Al_Cta

----------


Best regards!!!
