[RBG7-L] - Triggers before and after

[Bernard Lis]

This is my first foray into triggers and I would appreciate help.  This is 
what I have done:

I have 2 stored procedures:  demo3 and demo3b
what I want to do is capture the updated row before it is updated and after 
it is updated.  the before and after are inserted into table Emp_Tracker

alter table employee add trigger update demo3
when I list triggers, it shows up as an update trigger
alter table employee add trigger update after demo3b
list triggers and get:
update trigger: No Trigger Defined
After Update Trigger: demo3b
Why did the update trigger demo3  disappear?
Both of these triggers fire correctly when I do them one at a time.
