Components: core Versions: 3.2.0.ga Environment: INFO: Hibernate 3.2.0 INFO: RDBMS: MySQL, version: 5.0.22 INFO: JDBC driver: MySQL-AB JDBC Driver, version: mysql-connector-java-5.0.4 ( $Date: 2006-10-19 17:47:48 +0200 (Thu, 19 Oct 2006) $, $Revision: 5908 $ ) Reporter: Donnchadh O Donnabhain Attachments: HHH-2221.patch, JoinedSubclassTest.java I've created the following test (in JoinedSubclassTest) which reporduced the problem: public void testBulkUpdateJoinedSubclass() { Session s = openSession(); Transaction t = s.beginTransaction(); Employee mark = new Employee(); mark.setName("Mark"); mark.setTitle("internal sales"); mark.setSex('M'); mark.setAddress("buckhead"); mark.setZip("30305"); mark.setCountry("USA"); s.save(mark); String hql = "update Employee employee set employee.sex=:newSex where employee.id in (:ids)"; Query query = s.createQuery(hql); query.setCharacter("newSex", 'F'); List ids = new ArrayList(); ids.add(Long.valueOf(mark.getId())); query.setParameterList("ids", ids); query.executeUpdate(); s.delete(mark); t.commit(); s.close(); } and run it with the following properties: -Dhibernate.dialect=org.hibernate.dialect.MySQLDialect -Dhibernate.connection.driver_class=com.mysql.jdbc.Driver -Dhibernate.connection.url=jdbc:mysql://127.0.0.1/hibernateTest -Dhibernate.connection.username=username -Dhibernate.connection.password=password This produces the following error: org.hibernate.exception.SQLGrammarException: could not insert/select ids for bulk update at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:67) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.hql.ast.exec.MultiTableUpdateExecutor.execute(MultiTableUpdateExecutor.java:127) at org.hibernate.hql.ast.QueryTranslatorImpl.executeUpdate(QueryTranslatorImpl.java:396) at org.hibernate.engine.query.HQLQueryPlan.performExecuteUpdate(HQLQueryPlan.java:259) at org.hibernate.impl.SessionImpl.executeUpdate(SessionImpl.java:1141) at org.hibernate.impl.QueryImpl.executeUpdate(QueryImpl.java:94) at org.hibernate.test.joinedsubclass.JoinedSubclassTest.testBulkUpdateJoinedSubclass(JoinedSubclassTest.java:131) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:589) at junit.framework.TestCase.runTest(TestCase.java:164) at org.hibernate.test.TestCase.runTest(TestCase.java:247) at junit.framework.TestCase.runBare(TestCase.java:130) at org.hibernate.test.TestCase.runBare(TestCase.java:313) 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:120) at junit.framework.TestSuite.runTest(TestSuite.java:228) at junit.framework.TestSuite.run(TestSuite.java:223) at org.junit.internal.runners.OldTestClassRunner.run(OldTestClassRunner.java:35) 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: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Table 'hibernateTest.HT_JEmployee' doesn't exist at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:936) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:2870) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1573) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:1665) at com.mysql.jdbc.Connection.execSQL(Connection.java:3176) at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:1153) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:1404) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:1318) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:1303) at org.hibernate.hql.ast.exec.MultiTableUpdateExecutor.execute(MultiTableUpdateExecutor.java:118) ... 26 more This works fine in hibernate 3.1.3. The problem seems to be in AbstractStatementExecutor. It seems to assume that if a DDL statement, in general, results in a commit that this will also happen for a temporary table. In the case of MySQL, at least, this is not the case. The code in AbstractStatementExecutor goes and creates the temporary table in a new connection, which, in the case of MySQL, will not be visible in the current transaction. http://fisheye.jboss.com/browse/Hibernate/branches/Branch_3_2/Hibernate3/...
