MariaDB backend (but could be SQL Server too)
Given this trigger: UPDATE MyTable SET cItemID = new.cID WHERE
cItemID = old.cID
My question: will this trigger fire even if the old.cID = new.cID?
Or do I need to add to the WHERE clause something like "....and
old.cID <> new.cID"
My testing seems to indicate that I need to add the extra condition.
Makes total sense on re-thought. These triggers fire on just the
action, regardless of true change.
