Question

I want to save time intervals in my SQL table but I’m not sure what type to use in Java for this.

What I need to store are durations like 12:33:57 or just minutes and seconds like 02:19. Any ideas what type I could use for java and for sql? I don’t really need to make any calculations with these values, but I would like to generate charts later on, with the lengths of the mesured times.

Answer 1

The mysql type you want is TIME, ie:

create table mytable (
  ...
  my_interval TIME,
  ...
);

If you read such columns in via JDBC, you’ll get a java.sql.Time object, which is actually a java.util.Date with only the time portion set (ie a time on 1970-01-01)
