Kathey Marsden commented on DERBY-1130:
---------------------------------------

Your approach sounds ok to me, since the SQL states are already different.

> Currently this is allowed for client but should be disabled.  I think it is OK to change because we have documented that client will be changed to match embedded for implementation defined behaviour.   Hopefully its use is rare as most folks would use the standard setDatabaseName.  Still there should be a release not when the change is made and it would be better to change it sooner than later:
