> Query SQL Cache issue with NULL parameters
> ------------------------------------------
>
> Key: OPENJPA-2261
> URL: https://issues.apache.org/jira/browse/OPENJPA-2261
> Project: OpenJPA
> Issue Type: Bug
> Components: query
> Affects Versions: 2.1.0, 2.1.1, 2.2.0
> Reporter: Jody Grassel
> Assignee: Jody Grassel
>
> The Query SQL Cache matches previously executed SQL for a given JPQL by using
> the JPQL string itself for the key. As long as none of the predicate
> parameters are NULL, this is fine, as the prepared statement's SQL remains
> unchanged. Since SQL requires "column IS NULL" statements and not "column =
> NULL", the approach used by OpenJPA's Query SQL Cache breaks and results with
> bad getResultList() returns.
> In the future (say, trunk), the Query SQL Cache needs more intelligence to
> handle this situation, but for service releases the best way to handle this
> issue is to disqualify queries with NULL parameters from the query cache.
