- Using RAISE.
- Error propagation and transactional management.
Hands-on work
Use of RAISE and retrieval of error information.
6 Triggers

Distance learning is always a little more complicated than face-to-face training. The trainer was very competent, but distance learning prevents interaction between listeners.
