Hi,<br><br>I&#39;m trying to implement a custom QueryCache that, like the example in <a href="http://community.jboss.org/wiki/QueryCache" target="_blank">http://community.jboss.org/wiki/QueryCache</a>,
 does not invalidate some existing register is updated in a specific 
table. However, unlike the example, I&#39;d like to do that by analyzing 
which columns were changed in an update.<br>

<br>More precisely, I have an User table, which has a lastLogin column. 
I&#39;d like to keep the QueryCache valid when I update the lastLogin of an 
User.<br><br>I haven&#39;t found any way to do that yet. Is that possible?<br>

<br>Thanks in advance.<br clear="all"><br>--<br>Luiz F. O. Corte Real<br><br>Vida Geek<br><a href="http://vidageek.net/" target="_blank">http://vidageek.net</a><br><br>Caelum Objects<br><a href="http://www.caelumobjects.com/" target="_blank">http://www.caelumobjects.com</a>
