OJB report query

["Manukyan, Sergey" <SM...@lear.com>]

Folks,

How can I specify expressions in OJB report query?
I want it to select not a column but the sum of several columns,
The code here doesn't work, it failes to recognize the names of
field-descriptors. I use RC4.

Thank you,
-Sergey

		ReportQueryByCriteria qry =
			QueryFactory.newReportQuery(PartQuote.class,
criteria);

		qry.addOrderByAscending("partNum");
		qry.setColumns(
			new String[] {
				"partNum",
				"part.partDescription",
				"supplierReviewedQuote",
				"materialVariance + laborVariance +
burdenVariance + sellGenAdminVariance + profitVariance + toolingVariance +
packagingVariance + freightVariance + editVariance",
				"annualVolume",
				"supplierDeclinedQuote",
				"toolingRequired" });

		Collection report =
	
OJBBeanManager.getInstance().getReportByQuery(PartQuote.class, qry);
