Dbms_xmlgen.getxml not returning entire data set

Question

hi, i'm trying to return xml from oracle using the following: select dbms_xmlgen.getxml('select * from person') from dual, but it's not returning everything. it's returning data only up to a certain point. I've condensed it alot just so you'd get the gist, but in reality, there are about 50 columns in this table.
set pages 0
set linesize 150
set long 9999999
set head off
"(CLOB) <?xml version="1.0"?>
<ROWSET>
<ROW>
<name>joe smith</name>
<bday>1/1/2011</bday>
<citizen>yes</citizen>
</ROW>
<ROW>
<name>joe smith</name>
<bday>1/1/2011</bday>
<citizen>..."
i've even "set long 2000000000" as some people have recommended, but that didn't work either. what gives?
thanks!

Yes, it's a display issue.
In SQL*Plus, also set LONGCHUNKSIZE option :
SET LONG 10000
SET LONGCHUNKSIZE 10000Note : those are not "magic" values, you'll have to experiment a little to find what works best for your expected output.
What do you actually want to do with the XML data?
If it's really that big, why not write it to a file?
DECLARE
res CLOB;
BEGIN
select dbms_xmlgen.getxml('select * from person')
into res
from dual;
dbms_xslprocessor.clob2file(res, 'TEST_DIR', 'result.xml');
END;
