bulk import operations are forced to backup and restore much more often then needed.
Since changes to triggers don't imply structural changes to the table itself, Firebird no longer increments the table change counter when 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.
, Inter Base increments the metadata change counter of the associated table.
Once that counter reaches 255, no more metadata changes are possible on the table (you can still work with the data though).
CREATE or REPLACE TRIGGER emp_after_update AFTER UPDATE OF empid ON emp FOR EACH ROW DECLARE BEGIN update emp_backup set empid = :new.empid where empid = :old.empid; DBMS_OUTPUT.
PUT_LINE('empid successfully updated into emp_backup table'); END; The above trigger named ’emp_after_update’ will be initiated whenever ’empid’ column in ’emp’ table gets updated.
You can either replace any current time estimate with a new total, or you can increase or decrease the current estimated time on the task.
