TABLE statement will fail with an execution error. When a table is dropped, all triggers for its events and indexes built for its fields will be deleted as well.

for one specific event (insert, update, delete) or for some combination of two or three of those events. Two other forms of trigger exist: 1. a “database trigger” can be specified to fire at the start relation (table | view) events number Position of the trigger in the firing order.

A trigger can be created either for a relation (table | view) event (or a combination of events), for a database

application or as a service. Events Can't use Fiebird events if the server is be- hind a firewall or if connections are made through a secure tunnel. Can use Fiebird events under all circum- stances. If If the server is behind a firewall or if connections are made through a secure tunnel, a specific events port has to be as- signed to the RemoteAuxPort variable in firebird.conf, and the firewall or tun- Superserver. Firebird 2.0 and 2.1 Quick Start 6 • On Linux, just pick one or the other (unless you use events with a firewall or tunnel). In most circumstances, chances are that you won't notice a performance
