Are you trying to create a Rose Evolution server or a iRose server?
For Evolution;
Try re-installing the database, as stated above. Maybe that's the problem.
Also, make sure you didn't edit the Os Database, you might have edited something the wrong way, so the server doesn't understands the command given.
If that doesn't work, again, as stated above, try using a diffrent database, such as ''Roseon2''.
Then edit the ''Worldserver.conf, Charserver.conf and Loginserver.conf'' to the database ''Roseon2'' (Or anything else, just make sure it's the same as the databases name)
