> 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
> Assignee: Helen Xu

> 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?
