Ok. I have this query:

Select sum(stocks.stkreal)::text || ',' ||
sum(stocks.stkpteser)::text as stock
>From stocks, prendas
Where prendas.codprenda = stocks.codprenda and
prendas.codarticulo = '020720004';

And I want to create a function which receives
"codarticulo" as a parameter.

*----------------
Create Function calc_stocks(text) Returns text AS '
Declare
codart ALIAS For $1;
all_stocks record;
Begin
Execute '' Select sum(stocks.stkreal)::text || ''
|| '''''' ,''''''
|| '' || ''
|| ''sum(stocks.stkpteser)::text as stock ''
|| ''into all_stocks ''
|| ''From stocks, prendas ''
|| ''Where prendas.codprenda = stocks.codprenda and ''
|| ''prendas.codarticulo = codart; ''
Return all_stocks.stock;
End;
' language 'plpgsql';
*-----------------
gesyweb=# select calc_stocks('020220064');
