There is no simple query which allows you to identify the columns which were updated by a trigger. You will need to inspect (or, if you want to automate it, parse) the trigger code from column
RDB$TRIGGER_SOURCEto see which columns are assigned new values in the trigger code. Alternatively, you could parse the BLR (the compiled form) of the trigger from columnRDB$TRIGGER_BLRto see which columns are updated, but that will take some work on your part to write a a suitable parser of the BLR.
