Trigger error message

Hey guys I have just created a simple update trigger but I get the following message:

Warning: trigger created with compilation errors

I was just wondering what this means.

Thanks.

In which rdbms?

Oracle 10g.

Ummm, it means it was created with errors.

SQL> show errors

When you see the output from that (immediately after trying to compile again) and don't see or understand where/what the mistake was, post the output from "show errors."
