Using an Updatable ResultSet with an XSL Stylesheet
In addition to using the ResultSet for display purposes, it is very useful to be able to update the
database using the ResultSet itself. Updatable
ResultSet
s offer just this capability, in that they can
be updated directly. In other words, you can make updates to the values in the
ResultSet
itself, and
these changes are reflected in the database.
The XML-based and XSLT-based approach to creating a Web page lends itself well to use with
updatable
ResultSets
. One of the advantages of XS L is that you can create a completely different
Web page from the same XML by simply applying a different stylesheet. To illustrate this capability, try
applying the stylesheet shown in
Listing 15-12
to the original XML of
Listing 15-9
.
