XSU: OracleXMLSQLException thrown when column key is rowid.

Question

Hi All,
I run into a problem where I wanted to update a column which is the key. Let's say I have table
create table XYZ (
key varchar2(20),
name varchar2(20)
Using SQLPLUS, it is possible to do:
update XYZ
set (key='123', name='joe')
where
rowid='AAABrXAAEAAAJL1AAH';
rowid is the unique identifier assigned by oracle to each row.
the following is returned using OracleXMLQuery and saved into xml_file.
<rowset>
<row num="1">
<key>123</key>
<name>joe</name>
<rowid>AAABrXAAEAAAJL1AAH</rowid>
</row>
</rowset>
I change the value of key and name columns and I try to update the row using the following code:
OracleXMLSave query = new OracleXMLSave(conn, table);
keyColNames[0]= "rowid";
query.setKeyColumnList(keyColNames);
query.updateXML(xml_file);
An SQLException Exception is thrown:
oracle.xml.sql.OracleXMLSQLException: Column 'rowid', specified to be a key column, does not not exits in table 'XYZ'.
Since the updateXML method does not take the old and new value, is there a way to use a rowid as the unique Key to perform an update.
I will appreciate any help.
Thanks
Sa
