Re: Dynamic Array into pl/pgSQL function

There must be some kind of setting that needs to be set on my database that
isn't, because I have copied what you used nearly exactly, and I still get
this message: "WARNING: line 4 at for over select rows ERROR: parser:
parse error at or near "$1" at character 55"

The function I'm using is:
CREATE OR REPLACE FUNCTION public.practice(integer[])
RETURNS SETOF integer LANGUAGE 'plpgsql' AS '
DECLARE
i RECORD;
BEGIN
FOR i IN SELECT groupid FROM ClientInfo WHERE groupid = ANY ($1) LOOP
RETURN NEXT i.groupid;
END LOOP;
RETURN;
END;';

The statement I run against it is:
Select * from practice('{96,101,110,112}');

Any other ideas? I'm using 7.4.2

Thanks again,
Derrick
