Releases this rowset's <code>ResultSet</code> object's database and
JDBC resources immediately instead of waiting for
this to happen when it is automatically closed.

<P><B>Note:</B> A <code>ResultSet</code> object
is automatically closed by the
<code>Statement</code> object that generated it when
that <code>Statement</code> object is closed,
re-executed, or is used to retrieve the next result from a
sequence of multiple results. A <code>ResultSet</code> object
is also automatically closed when it is garbage collected.

@throws SQLException if a database access error occurs
