Hi,
I have written my first function, but I'm unable to execute it.
Here is the function body and error message.
CREATE OR REPLACE FUNCTION update_afdeling(update_type text, in_afd_id smallint, in_afd_omschrijving text, in_date_changed timestamp without time zone)
RETURNS integer AS
$BODY$
DECLARE
v_return smallint;
v_date_changed timestamp;
BEGIN
v_date_changed = NULL;

What I understand is : the function doesn't match the parameters in the call, but I don't have any idea what I'm doing wrong...
I already tried to replace the parameter types with VARCHAR instead of TEXT, but same error.
Many thanks in advance.
