Note

Identification of the exact RDB$TRIGGER_TYPE code is a little more complicated, since it is a bitmap, calculated according to which phase and events are covered and the order in which they are defined.For the curious, the calculation is explained in this code comment by Mark Rotteveel.

For DDL triggers, the trigger type is obtained by bitwise OR above the event phase (0 — BEFORE, 1 — AFTER) and all listed types events:
