Hi Kevin,
I can't find it in the Jira, but I added a comment on last Saturday, I downloaded the patched version apache-openjpa-2.0.0-beta\openjpa-all-2.0.0-svn-910423.jar to fix the issue however it did not fix the other issue of being able to use "+" symbol in my query.

So I'm stuck! Thanks Chris From: catalina wei [mailto:[email protected]] Sent: Saturday, 20 February 2010 10:33 PM To: [email protected]; [email protected] Subject: Re: Query confusion Chris, sum(dl.bwCount) * dl.bwRate is a scalar expression. In Java Persistence 1.0 spec, scalar expression is not allowed to appear as a select item. That is why you are getting a syntax error. JPQL in Java Persistence 2.0 spec has updated the syntax and the scalar expression can be a select item. This support is available in OpenJPA 2.0.x releases. Could you try any OpenJPA 2.0.x releases ? Catalina On Sat, Feb 20, 2010 at 12:03 AM, C N Davies <[email protected]> wrote: Thanks Daryl, Pretty obvious, why couldn't I see it! Now I see my next issue, here is my query truncated down to the specific issue: Select sum(dl.bwCount) * dl.bwRate from DLine as dl; <openjpa-1.2.1-r752877:753278 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: Encountered "*" at character 111, but expected: [",", "FROM"]. at org.apache.openjpa.kernel.jpql.JPQL.generateParseException(JPQL.java:9501) What is wrong with my "*" symbol? It is documented as supported. I tried like this: (sum(dl.bwCount) * dl.bwRate) Same issue L Thanks!

My above example will return an Object[]. Not especially easy to use, a Map would be nice. But there it is. -- Daryl Stultz _____________________________________ 6 Degrees Software and Consulting, Inc. http://www.6degrees.com mailto:[email protected]
