Xsql:query xml error

Question

I am getting an error when running an xsql:query. I can run simple queries, so it is not a connection porblem. The xml parses in jDeveloper10g so it appears to not be ill-formed XML. I have tried containing the SQL statement in CDATA tags, and tried replacing < and > with their entity references &lt; and & gt; and I have tried both at the same time.
The Query is as follows
<page xmlns:xsql="urn:oracle-xsql" connection="V7Test">
<xsql:query fetch-size="100" max-rows="-1" null-indicator="no" tag-case="lower">
<![CDATA[
select
ts_jobs.job_number,
sum(ts_jobs.period_hours),
ts.period_end_date
from
etr.etr_timesheet_days ts_days,
etr.etr_timesheet_hours ts_hours,
etr.etr_timesheet_jobs ts_jobs,
etr.etr_timesheets ts
where
ts_hours.hours != 0
and (
(nvl(ts_jobs.corrected_id,0) = 0
and nvl(ts_hours.corrected_id,0) = 0
and ts.date_sent_to_pmjcap >=ts_hours.date_entered)
or (ts.date_sent_to_pmjcap < ts_hours.date_corrected)
and ts_days.timesheet_day_id = ts_hours.timesheet_day_id
and (
(ts_days.period_date in ('01-JAN-03','02-JAN-03','03-JAN-03')
and ts.period_end_date = '03-JAN-03')
or (ts_days.period_date in ('27-DEC-03','28-DEC-03','29-DEC-03','30-DEC-03','31-DEC-03')
and ts.period_end_date = '02-JAN-04')
and ts_days.timesheet_id = ts.timesheet_id
and ts_jobs.timesheet_job_id = ts_hours.timesheet_job_id
and (
(ts_jobs.job_number in (9719003,9849003,9849001,9719001))
or (ts_jobs.job_number in (9719333,9849333,9849334,9719334))

or (ts_jobs.job_number in (9719444,9849444,9849445,9719445))
and ts.timesheet_id = ts_jobs.timesheet_id
and ts.employee_number = '050405'
and exists
(select

where
substr(job_number,-8) = ts_jobs.job_number
and date_incurred = ts.period_end_date
and emp_clock = lpad('050405',6,0)
group by
ts_jobs.job_number,
ts.period_end_date,
ts_hours.hours
]]>
</xsql:query>
The Error I get is as follows
<?xml version="1.0" encoding="windows-1252" ?>
- <!--
| Uncomment the following processing instruction and replace
| the stylesheet name to transform output of your XSQL Page using XSLT
<?xml-stylesheet type="text/xsl" href="YourStylesheet.xsl" ?>
-->
- <page>
<error>oracle.xml.sql.OracleXMLSQLException: Character ')' is not allowed in an XML tag name.</error>
</page>
I think it is parsing a '<' as a tag delimiter.
Anyone have a similiar problem? a workaround?

Answer 1

I found the answer. The problem is the selected 'column' sum(ts_jobs.period_hours). Apparently, the XSQL servlet attempts to assign the value 'sum(ts_jobs.period_hours)' directly to an XML element.total_hours. That fails.
The work-around is to use an alias. This code works
sum(ts_jobs.period_hours) total_hours,
A fix to the XSQL servlet would be in order, perhaps adding a CDATA container around 'columns' that are are normal SQL functions.
