[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4169) @SqlResultSetMapping gives Invalid Column for columns not in select clause

@SqlResultSetMapping gives Invalid Column for columns not in select clause -------------------------------------------------------------------------- Key: HHH-4169 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4169 Project: Hibernate Core Issue Type: Bug Components: entity-manager Environment: DB: Oracle 10g, OS: Win XP, Hibernate 3 using JPA entitymanager Reporter: Rachit Hi, A very simple usage of SqlResultSetMapping. I want to retrieve only country Name using native query. I have specified one column country name to be fetched and mapped in Object. @SqlResultSetMapping(name = "CountryCountry", entities = { @EntityResult(entityClass = Country.class, fields = { @FieldResult(name = "countryName", column = "COUNTRY_NAME") }) public void testComplexer0NativeQuery() { em = emf.createEntityManager(); Query query = em.createNativeQuery( "select iso.COUNTRY_NAME from Country iso", "CountryCountry"); List list = query.getResultList(); System.out.println(list.size()); System.out.println(list.get(0).getClass()); } Running this I get "INFO: could not read column value from result set: ISO1_2_0_; Invalid column name" exception. The whole stack trace : javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: could not execute query at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:614) at org.hibernate.ejb.QueryImpl.getResultList(QueryImpl.java:76) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:79) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:618) at junit.framework.TestCase.runTest(TestCase.java:168) at junit.framework.TestCase.runBare(TestCase.java:134) at org.springframework.test.ConditionalTestCase.runBare(ConditionalTestCase.java:76) at junit.framework.TestResult$1.protect(TestResult.java:110) at junit.framework.TestResult.runProtected(TestResult.java:128) at junit.framework.TestResult.run(TestResult.java:113) at junit.framework.TestCase.run(TestCase.java:124) at junit.framework.TestSuite.runTest(TestSuite.java:232) at junit.framework.TestSuite.run(TestSuite.java:227) at org.junit.internal.runners.JUnit38ClassRunner.run(JUnit38ClassRunner.java:81) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:38) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) Caused by: org.hibernate.exception.GenericJDBCException: could not execute query at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:126) at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:114) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.loader.Loader.doList(Loader.java:2231) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2125) at org.hibernate.loader.Loader.list(Loader.java:2120) at org.hibernate.loader.custom.CustomLoader.list(CustomLoader.java:312) at org.hibernate.impl.SessionImpl.listCustomQuery(SessionImpl.java:1722) at org.hibernate.impl.AbstractSessionImpl.list(AbstractSessionImpl.java:165) at org.hibernate.impl.SQLQueryImpl.list(SQLQueryImpl.java:175) at org.hibernate.ejb.QueryImpl.getResultList(QueryImpl.java:67) ... 21 more Caused by: java.sql.SQLException: Invalid column name at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:269) at oracle.jdbc.driver.OracleStatement.get_column_index(OracleStatement.java:6348) at oracle.jdbc.driver.OracleResultSetImpl.findColumn(OracleResultSetImpl.java:1557) at oracle.jdbc.driver.OracleResultSet.getString(OracleResultSet.java:1549) at org.hibernate.type.StringType.get(StringType.java:41) at org.hibernate.type.NullableType.nullSafeGet(NullableType.java:184) at org.hibernate.type.NullableType.nullSafeGet(NullableType.java:173) at org.hibernate.loader.Loader.getKeyFromResultSet(Loader.java:1121) at org.hibernate.loader.Loader.getRowFromResultSet(Loader.java:588) at org.hibernate.loader.Loader.doQuery(Loader.java:724) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:259) at org.hibernate.loader.Loader.doList(Loader.java:2228) ... 28 more Hibernate is trying to fetch all the columns present in entity to create the object. I am only interested in column/s I have specified in "@FieldResult". If I retrieve all fields in entity, It works fine though. Thanks and Regards.
