Some of the issues I've found with JPA 2.1 and the overall new stored procedure APIs:
1. StoredProcedureQuery#hasMoreResults() returns true if the next result is an update count, it should return false, according to API documentation. On MySQL, if a SP returns a single or multiple ResultSets, you also get an update count of 0. Internally it simply returns row_count() for the last SQL statement in the procedure if you invoke CallableStatement#getUpdateCount(). 2. If there is only one ResultSet returned by the SP, I should be able to call StoredProcedureQuery#getResultList() without first calling hasMoreResults(). This maps to JDBC CallableStatement#excuteQuery(). 3. When I try to read an OUT argument at index 2 with StoredProcedureQuery#getOutputParameterValue(), it only works if I get it with index 1. This seems like a simple offset bug. 4. Calling an SP which only returns an update count, I should be able to use only StoredProcedureQuery#executeUpdate(). This works in plain JDBC, currently I get an IllegalStateException because I haven't called hasMoreReturns() before. 5. Calling an SP which only returns an update count, the StoredProcedureQuery#execute() method should return false, it currently returns true, even if there is no ResultSet. 6. Calling an SP which only returns an update count is awkward with the Hibernate StoredProcedureCall API, involving several lines and casts to get the update count. 7. Note sure how to call/handle REF_CURSOR parameters in either API, doesn't seem to be implemented. _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
