Dan, you really need to pay more attention to what was written.
With respect to GPL I never talked about end users.
Just those who license their code under GPL.

you'd rename the existing table to a temp name, rebuild the table with all of

When you create a unique constraint on a table, why would you check to see if

Does this make sense?

Hi,
Quick question...
Has anyone tried using Derby/Cloudscape with the data being written to one of
those 512MB FOBs instead of a hard drive?
Got in to a discussion over a beer last night regarding "in memory" databases
vs solid state drives vs those FOBs that now have over a GB of storage.
