----------------------------------------
Created following jira for exception thrown when empty string is passed for
index name to update/drop statistics procedures
DERBY-5750 Sending an empty string as table name to compress table procedure or
empty string as index name to update statistics procedure makes the parser
throw an exception.
> Provide a way to drop statistics information

> Now that DERBY-269 has been resolved, users can update statistics, but once
> they do, they are committed to using and maintaining the statistics, even if
> it doesn't improve performance or they have difficulty maintaining the
> statistics on a regular basis. It would be good to have a way to drop
> statistics information so that users could revert to the prior behavior if
> needed.
