    Thankfully, a couple of My SQL’s internal features came to the rescue.Adding a modified timestamp to a table is the most straight forward.All your have to do is create the field of type in order for the next part to work (this is because setting NOT NULL forces an automatic all zeros default).Next, we must create a trigger, which will automatically be fired when we insert a value into our table and set the created timestamp.This becomes an issue when a table needs to have a created timestamp and a modified timestamp, and the developer does not want to or cannot use the development language to insert a timestamp into the database.Which field do you give the current timestamp default to? How does one ensure that these timestamps are always correctly updated?field in your insert query, it will be set to the current time stamp.

    I didn’t much fancy rewriting all of the SQL queries, potentially twice, just to add a couple of timestamps, so modifying code wasn’t much of an option.The TIMESTAMP data type is used to return value which also contains both date and time parts.The range of My SQL TIMESTAMP type is '1970-01-01 ' UTC to '2038-01-19 ' UTC.And no, you cannot set up a trigger for select statements.If you’re anything like me, you often find yourself needing to add create and modified timestamps to data stored in a My SQL database.
