The first warning reported by calls on this <code>CachedRowSetImpl</code>
object is returned. Subsequent <code>CachedRowSetImpl</code> warnings will
be chained to this <code>SQLWarning</code>. All <code>RowSetWarnings</code>
warnings are generated in the disconnected environment and remain a
seperate warning chain to that provided by the <code>getWarnings</code>
method.

<P>The warning chain is automatically cleared each time a new
row is read.

<P><B>Note:</B> This warning chain only covers warnings caused
by <code>CachedRowSet</code> (and their child interface)
methods. All <code>SQLWarnings</code> can be obtained using the
<code>getWarnings</code> method which tracks warnings generated
by the underlying JDBC driver.
@return the first SQLWarning or null
