Subject unwanted triggers present


in my db some tables have strange triggers: 'CHECK_X' ACTIVE POSITION 1 AFTER UPDATE or AFTER DELETE where the 'X' is a number. All these triggers are empty (seeing them with flamerobin).

I tried to delete them but after this i have had to restore a backup because the db was malfunctioning.

It was originally created with interbase and then moved to firebird.

The DB works properly but these 'presences' are very odd.


Thank you.
