Updating trigger mysql
I want to create a trigger which updates or insert values into Test Table2 as I insert values into Test Table. Date)))) THEN INSERT INTO Test Table2 (Item Id, Year, Month, Open, Close, Increase ) VALUES (NEW.
This is what the trigger i tried to create looked like, CREATE TRIGGER 'month Update Trigger' AFTER INSERT ON Test Table BEGIN IF NOT (EXISTS (SELECT 1 FROM Test Table2 WHERE (Item Id=NEW.
Triggers are useful for tasks such as enforcing business rules, validating input data, and keeping an audit trail. It's difficult to tell what is being asked here.column for the row as it was before the update statement was executed.I'm working in My SQL after using SQL Plus and am trying to create an after update trigger.I've tried doing a few variants, but I keep getting syntax errors.
