For those who might encounter a similar issue, merging what I had into a single entity and using getClobVal() did the trick.
In other words: <document> <entity name="doc" query="SELECT d.EFFECTIVE_DT, d.ARCHIVE_ID, d.XML.getClobVal() AS TEXT FROM DOC d" transformer="ClobTransformer"> <field column="EFFECTIVE_DT" name="effectiveDate" /> <field column="ARCHIVE_ID" name="id" /> <field column="TEXT" name="text" clob="true"> </entity> </document> Thanks. -----Original Message----- From: Craig Christman [mailto:cchrist...@caci.com] Sent: Wednesday, March 17, 2010 11:23 AM To: solr-user@lucene.apache.org Subject: RE: Indexing CLOB Column in Oracle To convert an XMLTYPE to CLOB use the getClobVal() method like this: SELECT d.XML.getClobVal() FROM DOC d WHERE d.ARCHIVE_ID = '${doc.ARCHIVE_ID}' -----Original Message----- From: Shawn Heisey [mailto:s...@elyograg.org] Sent: Tuesday, March 16, 2010 7:37 PM To: solr-user@lucene.apache.org Subject: Re: Indexing CLOB Column in Oracle Disclaimer: My Oracle experience is miniscule at best. I am also a beginner at Solr, so grab yourself the proverbial grain of salt. I googled a bit on CLOB. One page I found mentioned setting up a view to return the data type you want. Can you use the functions described on these pages in either the Solr query or a view? http://www.oradev.com/dbms_lob.jsp http://www.dba-oracle.com/t_dbms_lob.htm http://www.praetoriate.com/dbms_packages/ddp_dbms_lob.htm I also was trying to find a way to convert from xmltype directly to a string in a query, but that quickly got way over my level of understanding. I saw hints that it is possible, though.
