90        <p>
91        Under some (uncommon) situations a single SQL statement may return
92        multiple result sets and/or update counts. Normally you can ignore
93        this unless you are (1) executing a stored procedure that you know may
94        return multiple results or (2) you are dynamically executing an
95        unknown SQL string. The navigation through multiple results is covered by

99        The
100        <code>execute</code>

102        the form of the first result. You can then use

104        or
