Completely unnecessary in Oracle ... it is easily done in a single statement. There is a demo in Morgan's Library (www.psoug.org) under UPDATE. Search for "RETURNING CLAUSE."

Here's a simple example that returns multiple columns:

conn hr/hr

var bnd1 NUMBER
var bnd2 VARCHAR2(30)
var bnd3 NUMBER

UPDATE employees
SET job_id ='SA_MAN', salary = salary + 1000, department_id = 140
WHERE last_name = 'Jones'
RETURNING salary*0.25, last_name, department_id INTO :bnd1, :bnd2, :bnd3;

print bnd1
print bnd2
print bnd3

bnd1, 2, and 3, in PL/SQL, are variables.

The RETURNING CLAUSE can also be used with INSERTs and DELETEs.
