I'm wanting to drop a row/record/index in my Derby Embedded installation (pre-installed in ColdFusion 8 Developer's Edition), but the index-names aren't as simple as I had originally assumed (0, 1, 2,...).  I visited http://db.apache.org/derby/docs/10.3/ref/rrefsqlj59893.html to understand them, but it doesn't tell me how to determine what my indexes are named.  I haven't renamed them, so what's the default name, and how do I alter that name to obtain the Nth index?
