I'm trying to create a trigger to enforce a constraint onto two possible foreign tables
my function is defined as:
<-- snip -->
CREATE OR REPLACE FUNCTION sp_check_tranitem_productid(tbl_tranitem.fld_tranitem_id%TYPE,
tbl_tranitem.fld_tranitem_type%TYPE) RETURNS OPAQUE AS '
DECLARE
-------[Parameters]-------
pl_product_id ALIAS FOR $1;
pl_product_type ALIAS FOR $2;
<-- snip -->
but when I call the function I get the error:
function has no parameter $1
What is going wrong?
(I am using PostgreSQL 7.3.1)
