Trigger for data change?

Question

MySQL

Let's say we have a product table. It has an updateTime column. It is necessary to write down DATETIMESTAMP in it at any change of the data in this table. Those. recent changes. I think you need a trigger. Please help me write.

Answer 1

The trigger is not needed, mysql can do this on its own. ON UPDATE CURRENT_TIMESTAMP in a column declaration.
