Subject [jira] [Created] (OPENJPA-2176) QuerySQLCache not processing prepared sql correctly
Date Tue, 24 Apr 2012 13:55:33 GMT
Kevin Sutter created OPENJPA-2176:
-------------------------------------

             Summary: QuerySQLCache not processing prepared sql correctly
                 Key: OPENJPA-2176
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2176
             Project: OpenJPA
          Issue Type: Bug
          Components: query
    Affects Versions: 2.0.3, 2.1.2, 2.3.0, 2.2.1
            Reporter: Kevin Sutter


Opening this JIRA on behalf of a user e-mailing me with this question...  The workaround for
this problem is to disable the QuerySQLCache either via a property in the persistence.xml
or on an individual query basis via the setQueryHint invocation.  A description of the problem
follows:

I have a JPQL like this:
SELECT catentry FROM CatalogEntry catentry WHERE catentry.catalogEntryId IN(:catalogEntryId)

- catalogEntryId is of type long. 
- I am trying to set the named query parameter 'catalogEntryId' from my code using query.setParameter("catalogEntryId",
list of catalogEntryIds)
- I am ensuring that the list of catalogEntryIds that I am setting is always a list of type
java.lang.Long. I am using wrappers/objects rather than primitives. But I think that should
be OK, as the same is mentioned in the OpenJPA manual.

The issue is:
- When I start my server (on WAS), it works fine for the very first time. So let's say I pass
10459 & 10460 as catalogEntryIds, I get the entities corresponding to both the ids.
- But for subsequent requests, only one entity is returned mostly for the last id(10460) in
the list. There are no errors/exceptions thrown. I have in fact started the server in debug
mode and checked the exact values set in the query object. The "boundParams" in the QueryImpl
has the list of catalogEntryIds(10459 & 10460) that I have set.
- The issue is even more strange when I try to set a list of entities using the IN() expression
in another query which takes a list of entities as the query parameter. It works for the very
first time and then for subsequent requests it throws an exception saying parameter not supported/
invalid parameter...

Another strange behavior is that all the above works absolutely fine, when I launch the similar
code in a stand alone J2SE platform, typically using a JUNIT test case.

This problem looks very basic for a J2EE environment, I am hoping this is a known issue and
you have a fix already? 
About my environment:
- I am running with 1.0.0.5 of the OSGi/JPA 2.0 Feature Pack on top of WAS v7
- I have also set dataCache/queryCache to false hoping that would yield successful result,
but did not help. Seems like they are by default disabled?
