ANSI SQL and JDBC standards. Derby aims to be easy for developers
and end-users to work with.

    and two new commands: show tables and describe.

    to the server log file.

  o Identity columns can be reset to start at a new value.
  o New XML datatype and operators for storing and querying XML data
    have been introduced, based on SQL/XML 2006.

    JDBC escape functions.
