axel becker updated OPENJPA-2431:
---------------------------------
Priority: Blocker (was: Critical)
> Native-Query with multiple joins to same table returning wrong result
> ---------------------------------------------------------------------
>
> Key: OPENJPA-2431
> URL: https://issues.apache.org/jira/browse/OPENJPA-2431
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc, jpa, kernel, sql
> Affects Versions: 2.1.0, 2.1.1, 2.2.2
> Environment: Websphere 8 Runtime and Websphere ApplicationServer and
> without IBM classes (native TestNG)
> Windows XP
> J2EE 6
> Oracle 11
> Reporter: axel becker
> Priority: Blocker
> Attachments: resultlist.jpeg, TestEntityCurrencyReadonly.java,
> TestEntityImmutableIT.sql, testentityimmutable.jpa.xml,
> TestEntityIndexReadonly.java, TestEntityTenorReadonly.java,
> TestEntityTypeReadonly.java, TestReadonlyPrimaryKey.java
>
>
> The resultset of the following native query should has a result of an
> objectarray with 3 different returnvalues.
> 1) TestEntityIndexReadonly: the holder entity mapped to table indexes
> 2) TestEntityCurrencyReadonly: currency mapped to table types
> 3) TestEntityTenorReadonly: tenor mapped to table types too
> But i get an Resultset with 3 Objects where the second and the third object
> are the same (same instance).
> 1) TestEntityIndexReadonly:
> 2) TestEntityCurrencyReadonly:
> 3) TestEntityCurrencyReadonly:
> The Query:
> <named-native-query name="TestEntityIndexReadonly.findByDueDate"
>
> result-set-mapping="TestEntityIndexReadonly.findByDueDateResult">
> <query>
> <![CDATA[
> SELECT id.*, cur.*, tenor.*
> FROM indexes id
> LEFT JOIN types cur ON cur.t_id = id.id_t_cur_id
> LEFT JOIN types tenor ON tenor.t_id = id.id_t_tenor_id
> ]]>
> </query>
> </named-native-query>
> <!-- ResultSets -->
> <sql-result-set-mapping
> name="TestEntityIndexReadonly.findByDueDateResult">
> <entity-result
> entity-class="de.test.openjpa.TestEntityIndexReadonly" />
> <entity-result
> entity-class="de.test.openjpa.TestEntityCurrencyReadonly" />
> <entity-result
> entity-class="de.test.openjpa.TestEntityTenorReadonly" />
> </sql-result-set-mapping>
> Hint: For the entity-3 i get the same oid as for entity-2. The reason is, the
> JDBCStoreManager (Line 1031) "Object oid = base.getObjectId(this, result,
> null, true, null);" gets the same oid for entity-2 and entity-3.
> I will attache the javaclasses and mapping.xml and a screen from the wrong
> resultset.
> see also: https://issues.apache.org/jira/browse/openjpa-2218.
> I tried to find out a workaround by removing the abstract parent from
> TestEntityCurrencyReadonly and TestEntityTenorReadonly.
> In this case, i get the correct Objectinstances but the third entity
> (TestEntityTenorReadonly) holds the values from TestEntityCurrencyReadonly
> (also wrong)!
> Hope it helps to find the bug.
