Hi, I have two table "TAB_H" and "TAB_R".
Table TAB_R have a trigger "TAB_R_AD0" on after delete.

Deleting a record from "TAB_H" cause a cascade deleting on "TAB_R".

On the trigger TAB_R_AD0 I would distinguish the two record deleting
from TAB_R:
a) Explicit deleting (By User)
DELETE FROM TAB_R WHERE ...
b) Cascade deleting (By Engine)
DELETE FROM TAB_H WHERE PK_TAB_H="X"
=>
DELETE FROM TAB_R WHERE FK_TAB_H="X"

N.B.
I cannot use MON$ tables for this because I have more DELETE FROM
TAB_R (see above A) in the same transaction.

Thanks in advance.
