update Timestamp Cell in Sqlite

I have An Sqlite Database and I have an extra cell in it with a Timestamp item. The timestamp should display the last operation done with the row. (Z.B. has been updated) so everytime The row changes I want the timestamp to become the current timestamp. Especially when I query the row. In general I would now create a timestamp object and then update my row with the new timestamp.

But since this seems like a common operation which I think a lot of people have done I wonder If there is an other solution to register the last call of an object in a database. How would you do that?
