4GL Database Events

Database triggers associate a table or field with a database event. When the event occurs, the trigger executes. Progress does not provide events for all database actions. For example, although you can dump database definitions from a database, you cannot write a trigger for a DUMP event, because Progress does not provide a DUMP event.

However, Progress does provide replication-related triggers in addition to standard triggers for certain events. Replication-related triggers help you implement database replication. For more information on replication-related triggers, refer to the Progress Programming Handbook.

The database events that Progress 4GL supports follow.
