output parameters in functions

[UngaWunga]

Can someone tell me what's wrong with this syntax?


CREATE OR REPLACE FUNCTION Foo(bigint, out int, out boolean )
RETURNS record AS
$BODY$
begin
$2 := 0;
$3 := false;
end
$BODY$
LANGUAGE 'plpgsql';


CREATE OR REPLACE FUNCTION bar( bigint )
RETURNS int AS
$BODY$
declare aa int;
bb boolean;
begin
aa := 1;
bb := false;
select Foo( $1, out aa, out bb );
return aa;
end
$BODY$
LANGUAGE 'plpgsql';

[CODE=sql]
CREATE OR REPLACE FUNCTION Foo(bigint, out int, out boolean )
... ... ...

CREATE OR REPLACE FUNCTION bar( bigint )
... ... ...
select Foo( $1, out aa, out bb );

I don't think you can pass the OUT parameters when calling a function.
Try this:
[CODE=sql]
select Foo ($1);
[/CODE]
