That might make it even faster. But to be honest, I haven’t tested that.

Even if a trigger body with only “null;” in it will incur much more overhead than without the trigger at all. If your customer wants the triggers to be re-enabled, regardless of the status of overnight job, then the update script should re-enable the triggers and send an error that the job failed.

Ever heard of a function called LEAST?
