Subject [jira] Created: (OPENJPA-208) NoResultException and NonUniqueResultException are not thrown when expected
Date Fri, 06 Apr 2007 22:27:32 GMT
NoResultException and NonUniqueResultException are not thrown when expected
---------------------------------------------------------------------------

                 Key: OPENJPA-208
                 URL: https://issues.apache.org/jira/browse/OPENJPA-208
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
    Affects Versions: 0.9.6
            Reporter: Marc Prud'hommeaux
         Assigned To: Marc Prud'hommeaux


When calling Query.getSingleResult() on a query that either has no result or multiple results,
either a NoResultException and NonUniqueResultException (respectively) should be thrown in
accordance with section 3.6.1 of the JPA spec. Instead, we appear to throw a org.apache.openjpa.persistence.InvalidStateException:

org.apache.openjpa.persistence.InvalidStateException: The query on candidate type "class com.sun.ts.tests.ejb30.persistence.query.apitests.Department"
with filter "select d.name from Department d where d.id > 1" was configured to have a unique
result, but more than one instance matched the query.
