DROP TRIGGER
Restriction on dropping used triggers
Changed in: 2.0, 2.0.1
Description
In Firebird 2.0 only, a restriction is in place which prevents anyone from dropping, altering or recreating a trigger or stored procedure if it has been used since the database was opened. This restriction has been removed again in version 2.0.1.
Still, performing these operations on a live database is potentially risky and should only be done with the utmost care.
DROP TRIGGER no longer increments table change count
Changed in: 1.0
Description
In contrast to InterBase, Firebird does not increment the metadata change counter of the associated table when CREATE, ALTER or DROP TRIGGER is used. For a full discussion, see ALTER TRIGGER no longer increments table change count.
