Got it. Now I understand better. You want to pass the userid of your 'logged in user' to track the change in the database instead of using the user id that the datasource is logged in as.
I don't see any way for you to do this without changing your code. Maybe someone else can come up with something, but I just don't see any way around it. Whether you change it to implement the idea you had below or do it some other way, bottom line is, you will need to change your code to make Oracle aware of each individual user's ID. You might still be able to find a way to use the triggers, but I still think you'll need a code change. Sorry, no help.

Thanks again for your reply. Unfortunately, I need to pass the userid prior to executing each query as otherwise the auditing function would not know the userid. We have triggers on tables but triggers need the read the userid apriori. ColdFusion does not allow us to build our connection string dynamically or to dynamically inject connection string variables (such as the userid), as is the case with VB.NET and C#. This is why I am looking for an alternative. >Joseph, > >I think Gert's suggestion earlier could work for you.
