Hi,
I have a little trouble. I'm newbie in postgresql.

Consider this function example:

create or replace function testcall(int4,varchar,bool,int2) return setof record as '
declare
	r record;
	a int4;
	b varchar;
	c bool;
	d int2;
begin
	a=$1;
	b=$2;
	c=$3;
	d=$4;

	for r in select * from "T_Customer" loop
		return next r;
	end loop;

	return r;
end;'
language 'plpgsql'


when i tried to call it using:
select * from testcall(12,'ABCD',true,20000);

it says:
ERROR:  function testcall(integer, "unknown", boolean, integer) does not exist

then I tried to change to:
select * from testcall(12,varchar'ABCD',true,20000);

it says:
ERROR:  function testcall(integer, character varying, boolean, integer) does not exist

I've tried them using jdbc prepared statement and callable statement (both with/without parameters), but the result is the same.
what should i do?

Thanks

William
