Oracle database on ASP model - question

Question

my orale 8i database is running on sun solaris and the whole
front end is an ASP model product.
for every customer we have separate schemas and the same set of
all database objects are there in every schema.
this is going well.
my questions is: instead of putting the same set of pl/sql
procedures & functions into every schemas. Is it possible to have
a centralized procedure & function and whenever invoked, it
should work on the invoked schema's tables.
any ideas would help.
(the reason i'm asking is, it is hard to maintain the version of
the procedures & functions across the schemas)

Answer 1

use AUTHID CURRENT_USER
CREATE OR REPLACE PROCEDURE TEST AUTHID CURRENT_USER
IS
BEGIN
SELECT * FROM MYTABLE;
END TEST;
THIS PACKAGE NEEDS TO COMPILE IN A SCHEMA THAT HAS AL THE UNDERLAYING OBJECTS .
MYTABLE WILL BE USED FROM THE 'CURRENT' SCHEMA.
It is also possible to create 1 schema for all companies using oracle policies (DBMS_RLS)
