If I have a trigger that is executed on updates to TableA, is there an issue if I update 100 records on TableA in one update statement? I suspect that the trigger will run 100 times for each record. Is that correct or will it only run once? I’ve been warned that updating multiple records on one update statement might cause an issue.
If the trigger is defined as
FOR EACH ROWthen it will fire once for each row updated, i.e. 100 times in total. If notFOR EACH ROWit will just fire once.
