> Missing IN or OUT parameter exception with OracleDictionary
> -----------------------------------------------------------
>
> Key: OPENJPA-2131
> URL: https://issues.apache.org/jira/browse/OPENJPA-2131
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.1.1
> Environment: Windows with Oracle 11g
> Reporter: Zilin Chen
> Assignee: Albert Lee
> Fix For: 2.3.0
>
> Attachments: OPENJPA-2131.22x.patch, OracleInOutParameterIssue.patch
>
>
> We have generate query with
> Query q = em.createQuery("select e._name, e._id, sum(case when
> e._status=:pending then e._count else 0 end) from Exceptions e, Historty h
> where e._guid = :guid and .....
> then set paramenters for both :pending (in select) and :guid (in where), and
> call q.setMaxResults(100);
> with DB2, everything works fine, and DBDictionary.getSelects() and
> SQLBuffer.append() will invoke correctly and set parameter of :pending
> with Oracle implementation, OracleDictionary.getSelects(Select sel, boolean
> distinctIdentifiers, boolean forUpdate) will invoke and SQLBuffer.getSQL()
> get to call (as two if checks are not satisfied and gos to create a new
> SQLBuffer instance), but this time :pending parameter will missing to add to
> _param List,
> Eventually, we'll get Missing IN or OUT parameter exception from to execute
> query by preparedStatement
> This bug exist in both this branch and trunk.
> We have a work around, after SQLBuffer.getSQL() call, add some code to reset
> _param list.
