Hi there,
here is something I don't quite grasp (PG 9.1.3): This function:
CREATE OR REPLACE FUNCTION f_aliastest()
RETURNS setof text AS
$BODY$
declare sql text;
begin
sql:='SELECT ''sometext''::text as alias';
return query execute SQL;
end;
$BODY$
LANGUAGE plpgsql VOLATILE;
returns its result as:
contactking=# select * from f_aliastest();
f_aliastest
-------------
sometext
(1 row)
I was hoping I'd get the data back as 'alias', not as 'f_aliastest'.
If I do:
contactking=# select alias from f_aliastest();
ERROR: column "alias" does not exist
LINE 1: select alias from f_aliastest();
Is there a way that I can make my function return the field aliases?
Best wishes from Berlin,

You can use AS
select f_aliastest() AS alias;
