Typically in a database program like this you'll end up updating rows based on the primary key of the database table.Specifically, in this example, you'd probably already know the "id" for the user Fred, and when you go to update Fred's data, you would normally do it like this: +----+------------+-----------+---------------------+----------+------------+ | id | first_name | last_name | date_created | is_admin | num_points | +----+------------+-----------+---------------------+----------+------------+ | 2 | Fred | Flinstone | 2010-06-23 | 0 | 6000 | +----+------------+-----------+---------------------+----------+------------+ 1 row in set (0.00 sec) In "real world" Java database programs I almost always use the Spring JDBC libraries to access a database, but when you're first getting started, or working on small programs, I think it's important to see examples like this so you can understand how things work under the covers.
