Thanks for the tip—I'll keep that close at hand.

This is during development only, and I've got a copy of some production data in my development tables. When I delete the records created by my testing, I like to have the counter reset.

Now that I think about it, though, it's probably not all that important, since when I move the tables back into production (I've modified the structures) the identity fields probably aren't copied over with it. They should correct themselves according to the table they're in, yes?

IOW, like so:
   Test     Prod
  ------   ------
    1        1
    2        2
    3        3
    7        4
    8        5
    9        6
Correct?
