Dear friends,
 
Opening the table RDB$TRIGGERS, I saw many rows where the column RDB$TRIGGER_SOURCE is empty (null or an empty string). And the related tables doesn´t present these triggers.
 
I ask you:
-Are these rows at RDB$TRIGGERS useless ?
-May I delete these rows ?
-If I delete these rows, may I cause some any kind of trouble to my database ? Will this delection be helpful for the DB ? This way, will this delection affect the DB operation in any way, positive or negatively ?
 
Thanks a lot,
Roberto Camargo
