The original issue [1] https://issues.apache.org/jira/browse/OPENJPA-703 Some documentation [2] https://issues.apache.org/jira/secure/attachment/12399852/PreparedQueryCache.pdf > Have we done any testing with multi-valued 'in' clauses + prepared SQL? See org.apache.openjpa.persistence.jdbc.sqlcache.TestPreparedQueryCache has tests with IN clauses. But the parameters were not PCs. And it surely is broken for Collection<PC> case. Consider bypassing the cache for broken cases using several ways to deactivate the cache for a single query/transaction/session, when it is broken.[3] [3] http://openjpa.apache.org/builds/latest/docs/manual/manual.html#ref_guide_cache_querysql ----- Pinaki -- View this message in context: http://openjpa.208410.n2.nabble.com/prepared-SQL-bug-question-tp5314469p5322498.html Sent from the OpenJPA Developers mailing list archive at Nabble.com.
