XML transform and ORA-06502:

Question

When i update a limited set ( 1 row) of data with the statement in example 1 the statement works fine. When i delete the where clause i get ORA-06502: numeric or value error: character string buffer too small.
How can i make the statement work for a large amount of data.
example 1:
update udo.udo_cursus_beschrijvingen cbg
SET cbg.tekst = cbg.tekst.transform(XMLType(
'<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="url[(starts-with(child::text(),''www.''))]">
<url>http://<xsl:value-of select="."/></url>
</xsl:template>
<xsl:template match="@*|*|text()|processing-instruction()">
<xsl:copy>
<xsl:apply-templates select="@*|*|text()|processing-instruction()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
')).getStringVal()
where cbg.id = 1672;

Sergio - I'm surprised that a hundred rows causes the Display As Text (based on LOV, save/does not save the state) to blow out. I'd expect no problems up to 5000 rows or so. I'd like to see an example of your case. The limitation on select lists is usually related to either the size of an individual report column (4000 max) or the size of a report row (32K max) in which a select-list lov is used. The total size of the HTML returned counts towards these limits. The problem for select-list items on a page is that large select lists mean lots of HTML on the page making the page heavy and burdening the network.
