Yes, I have tried this:

Create Function calc_stocks(text) Returns text AS '
Declare
codart ALIAS For $1;
all_stocks record;
stock text;
Begin
Select sum(stocks.stkreal) as stock1,
sum(stocks.stkpteser) as stock2
into all_stocks
From stocks, prendas
Where prendas.codprenda = stocks.codprenda and
prendas.codarticulo = codart;
stock := (all_stocks.stock1::text ||
all_stocks.stock2::text);
Return stock;
End;
' language 'plpgsql';

But now I have got neither error nor
result.

gesyweb=# select calc_stocks('020220064');
calc_stocks
-------------
