The result data type is not related to your existing table. You're using the datatype char for both result columns.
That type is padded with spaces.
I would always advise to use varchar(n) or "text" unless you need the result to be exacly some length, like 254.
However you seem to be using numbers, why don't you use the "integer" data type?

I want to migrate from MS Sqlserver 2008 r2 express to Postgresql
I use postgresql 9.1.3
I create this stored function (on Postgres side)
CREATE OR REPLACE FUNCTION public.a_getkonta_table (
mkontoa char,
mkontob char
)
RETURNS TABLE (
kontochar,
naziv char
) AS
$body$
begin
return query
SELECT
konta.konto,
konta.naziv
FROM konta
WHERE konta.konto between mkontoa and mkontob;
end ;
$body$
LANGUAGE 'plpgsql'
VOLATILE
CALLED ON NULL INPUT
SECURITY INVOKER
COST 100 ROWS 1000;
I call this function with this code (from Microsoft VisualFoxPro side)
mkontoa = '000000000'
mkontob = '099999999'
If SQLExec(handle,"select * from a_getkonta_table(?mkontoa,?mkontob)",'temp101') < 0
Aerror(laError)
Messagebox(laError[1,2])
return
ENDIF
Returned result set contains correct row numbers but fields length is 254.
Structure of table konta is
Konto char(9)
Naziv char(45)
I use this connection string:
Connstr="DRIVER={PostgreSQL odbc driver(unicode)};server=localhost;Port=5432;Database=mydatabase; Uid=postgres;Pwd=mypwd; UseServerSidePrepare=1;MaxVarcharSize=254;UnknownsAsLongVarchar=0;TextAsLongVarchar=0;" OS Window 7 profesional
Any solutions ?
