I agree that Derby needs to reserve a part of the namespace for future system schema names. But I find it unreasonable to reserve all names starting with "SYS" because "SYSTEM" is a very common word and that this would disallow schema names like "SYSTEM_DIAGNOSTICS", "SYSTEM_STATUS" etc. A common prefix like this might be a hurdle for porting existing schemas and applications to Derby (that's the way I discovered the restriction). I also see from the comments in the code that this restriction was added as a DB2-compliance, and think that we should revert this restriction. The best approach would probably be to add a non-standard character to the identifiers so that a non-standard prefix could be used. E.g. "SYS$". -- Bernt Marius Johnsen, Database Technology Group, Sun Microsystems, Trondheim, Norway
