RE: DB2 Auto-update TimeStamp



fixed

Why are you issuing an update on a database table when no updates have occurred? That is terrible programming practice.

I know you can add a timestamp to a table that automatically updates on insert and update. But can you have it only update if there is a real change in the data? For example if a update is done to the table but no data changes I would like for it not to update the timestamp. My guess is no it's not possible but thought I would ask.


myTimeStamp TIMESTAMP NOT NULL GENERATED BY DEFAULT FOR EACH ROW ON UPDATE AS ROW CHANGE TIMESTAMP
