Hi I believe I just discovered little bug in Hibernate 3.2.1. If you have a table named VC and a column with the same name (VC) and you define this HQL: Strinh hbsql="update VC set timestamp='xxxx' where VC =:vcId" session.createQuery(hbsql).setString("vcId", aVC.getVcId()).executeUpdate(); You will get a Nullpointer in SessionFactoryHelper.findSQLFunction there is a easy workaround, just rename the VC java object to something different then the column name. I post it here and maybe someone wll be helped by it, it took me some hours before I found it. I believe this occured in 3.2.1 because it has worked in an erlier version, 3.0.x. (don't rember exactly which we used earlier) Here is a trace: java.lang.NullPointerException at org.hibernate.hql.ast.util.SessionFactoryHelper.findSQLFunction(SessionF actoryHelper.java:342) at org.hibernate.hql.ast.tree.IdentNode.getDataType(IdentNode.java:266) at org.hibernate.hql.ast.tree.BinaryLogicOperatorNode.extractDataType(Binar yLogicOperatorNode.java:168) at org.hibernate.hql.ast.tree.BinaryLogicOperatorNode.initialize(BinaryLogi cOperatorNode.java:34) at org.hibernate.hql.ast.HqlSqlWalker.prepareLogicOperator(HqlSqlWalker.jav a:1006) at org.hibernate.hql.antlr.HqlSqlBaseWalker.comparisonExpr(HqlSqlBaseWalker .java:3992) at org.hibernate.hql.antlr.HqlSqlBaseWalker.logicalExpr(HqlSqlBaseWalker.ja va:1762) at org.hibernate.hql.antlr.HqlSqlBaseWalker.logicalExpr(HqlSqlBaseWalker.ja va:1690) at org.hibernate.hql.antlr.HqlSqlBaseWalker.logicalExpr(HqlSqlBaseWalker.ja va:1687) at org.hibernate.hql.antlr.HqlSqlBaseWalker.whereClause(HqlSqlBaseWalker.ja va:776) at org.hibernate.hql.antlr.HqlSqlBaseWalker.updateStatement(HqlSqlBaseWalke r.java:358) at org.hibernate.hql.antlr.HqlSqlBaseWalker.statement(HqlSqlBaseWalker.java :237) at org.hibernate.hql.ast.QueryTranslatorImpl.analyze(QueryTranslatorImpl.ja va:228) at org.hibernate.hql.ast.QueryTranslatorImpl.doCompile(QueryTranslatorImpl. java:160) at org.hibernate.hql.ast.QueryTranslatorImpl.compile(QueryTranslatorImpl.ja va:111) at org.hibernate.engine.query.HQLQueryPlan.<init>(HQLQueryPlan.java:77) at org.hibernate.engine.query.HQLQueryPlan.<init>(HQLQueryPlan.java:56) at org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan(QueryPlanCache .java:72) at org.hibernate.impl.AbstractSessionImpl.getHQLQueryPlan(AbstractSessionIm pl.java:133) at org.hibernate.impl.AbstractSessionImpl.createQuery(AbstractSessionImpl.j ava:112) at org.hibernate.impl.SessionImpl.createQuery(SessionImpl.java:1623) at com.teliasonera.wal.inventory.atmpvc.dao.SybaseATMPVCDAO.updateVC(Sybase ATMPVCDAO.java:398) at com.teliasonera.wal.inventory.atmpvc.ATMPVCHandler.updateVC(ATMPVCHandle r.java:203) at com.teliasonera.wal.inventory.atmpvc.ATMPVCHandler.updateVC(ATMPVCHandle r.java:197) at com.teliasonera.wal.inventory.atmpvc.ATMPVCHandlerTest.testUpdateVC(ATMP VCHandlerTest.java:164) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.jav a:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessor Impl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at junit.framework.TestCase.runTest(TestCase.java:154) at junit.framework.TestCase.runBare(TestCase.java:127) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUn it3TestReference.java:128) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.ja va:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTe stRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTe stRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRun ner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRu nner.java:196)

[Hibernate-JIRA] Created: (HHH-2043) There is an bug in InformixDialect preventing generator-class=native to work.

by Andrew from Poland (JIRA)

There is an bug in InformixDialect preventing generator-class=native to work. ----------------------------------------------------------------------------- Key: HHH-2043 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2043 Project: Hibernate3 Type: Bug Components: query-sql Versions: 3.1.3, 3.2.0 cr1, 3.2.0.cr2, 3.2.0.cr3, 3.2.0.cr4 Environment: hibernate version 3.1.3, IBM Informix Dynamic Server Version 10.00.FC3R1, JDBC IBM Informix driver ver 3.0.JC3 (ifxjdbc-3.0-jc3.jar) Reporter: Andrew from Poland Priority: Minor When there is an column of SERIAL or SERIAL8 type (identity types in Informix) database expect this column to appear in INSERT clause with value equal 0, for example: INSERT into my_table (my_serial_column, other_column) values (0, "some value"); - in this example my_serial_column is an identity column. Using current InformixDialect this insert looks like this: INSERT into my_table (other_column) values ( "some value"); which causes an exception: java.sql.SQLException: Error In Specifying Automatically (Server) Generated Keys. at com.informix.util.IfxErrMsg.getSQLException(IfxErrMsg.java:373) at com.informix.jdbc.IfxSqli.a(IfxSqli.java:3208) at com.informix.jdbc.IfxSqli.E(IfxSqli.java:3518) at com.informix.jdbc.IfxSqli.dispatchMsg(IfxSqli.java:2353) at com.informix.jdbc.IfxSqli.receiveMessage(IfxSqli.java:2269) at com.informix.jdbc.IfxSqli.executePrepare(IfxSqli.java:1153) at com.informix.jdbc.IfxPreparedStatement.e(IfxPreparedStatement.java:318) at com.informix.jdbc.IfxPreparedStatement.a(IfxPreparedStatement.java:298) at com.informix.jdbc.IfxPreparedStatement.<init>(IfxPreparedStatement.java:275) at com.informix.jdbc.IfxSqliConnect.prepareStatement(IfxSqliConnect.java:2077) at org.apache.commons.dbcp.DelegatingConnection.prepareStatement(DelegatingConnection.java:418) at org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.prepareStatement(PoolingDataSource.java:385) 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:585) at org.hibernate.jdbc.BorrowedConnectionProxy.invoke(BorrowedConnectionProxy.java:40) at $Proxy10.prepareStatement(Unknown Source) ...

[Hibernate-JIRA] Commented: (HHH-1512) Problem to lock a row in a DB2 database with LockMode UPGRADE

by Milosz Tylenda (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1512?page=c... ] Milosz Tylenda commented on HHH-1512: ------------------------------------- I run the tests using current SVN snapshot and DB2 9.1. Actually JPALockTest hangs up in both testLockModeTypeRead and testLockModeTypeWrite methods when run on DB2 - no matter which of 1-7 statements we choose. Even if we remove all for update/read only/with stuff from SELECTs, the test still hangs. This is because DB2 locks rows "aggressively" - after transaction 1 have updated a row, transaction 2 tries to select this row and hangs until transaction 1 commits/rolls back. That is the case even if transactions use Cursor Stability (=JDBC's Read Committed) isolation level. I opened two command line clients, switched auto-commit off and checked which phenomena statements 1-7 prevent. The results are as follows: 1) prevents dirty reads, concurrent writes, concurrent reads 2) prevents dirty reads, concurrent writes, concurrent reads 3) prevents only uncommitted reads 4) prevents dirty reads, concurrent writes 5) prevents dirty reads, concurrent writes, concurrent reads 6) prevents dirty reads, concurrent writes, concurrent reads 7) prevents dirty reads, concurrent writes, concurrent reads (even if the concurrent transaction uses select without update/read only/with clause) It seems that if we want to prevent only dirty reads and concurrent writes, the current DB2Dialect is OK. If we also want to prevent concurrent reads, we should use one of 1, 2, 5, 6, 7. Maybe it can make Hibernate more portable across databases. > Problem to lock a row in a DB2 database with LockMode UPGRADE > ------------------------------------------------------------- > > Key: HHH-1512 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1512 > Project: Hibernate3 > Type: Bug > Components: core > Versions: 3.1 > Environment: DB2 v8.2, Hibernate 3.1 and higher > Reporter: Peter Potthoff > Assignee: Steve Ebersole > Attachments: locks.txt > > Original Estimate: 1 hour > Remaining: 1 hour > > Using the LockMode UPGRADE to lock a row in the database, this will result in > a sql-statement: select ID from <schema>.<table> where ID =? and version =? for read only with rs > This statement produces a shared lock and cannot be used for pessimistic locking because > this kind of lock won't stop a concurrent thread from accessing the data. > The source of the class DB2Dialect.java was changed from release 1.34 to 1.35: > http://cvs.sourceforge.net/viewcvs.py/hibernate/Hibernate3/src/org/hibern... > and from 1.33 to 1.34 > http://cvs.sourceforge.net/viewcvs.py/hibernate/Hibernate3/src/org/hibern... > Please take a look at: HHH-378 and http://forum.hibernate.org/viewtopic.php?t=954639&highlight=db2+lock+upgrade -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2312) criteria with annotation mapping leads to bad join on a 1:n:n relation

[Hibernate-JIRA] Created: (HHH-2231) Using "create table" strictly from org.hibernate.dialect.Dialect

by Mark Gorokhov (JIRA)

Using "create table" strictly from org.hibernate.dialect.Dialect ---------------------------------------------------------------- Key: HHH-2231 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2231 Project: Hibernate3 Type: Improvement Components: core Versions: 3.2.0.ga Environment: Hibernate v 3.2.0, October 16, 2006, HSQLDB 1.8.0.7 (Using In-process mode) Reporter: Mark Gorokhov Priority: Trivial Configuration property setProperty(Environment.HBM2DDL_AUTO, "update") automatically create missing HSQLDB In-process database. HSQL default "create table" is converted to "create memory table". Hibernate does not provide an option to convert "create table" into "create cached table". A keyword "create table" could be found in Hibernate core in many places, including org.hibernate.mapping.Table without an option to override "create table" behavior. Proposed: add method Dialect.getCreateTableString() similar to to Dialect.getCreateTemporaryTableString() and use it everywere in the code where "create table" is required. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Commented: (HHH-1915) DerbyDialect javadoc

by Steve Ebersole (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1915?page=c... ] Steve Ebersole commented on HHH-1915: ------------------------------------- Because our test suite shows problems running against Derby using IDENTITY columns. It almost as if in certain circumstances the just inserted IDENTITY value is not available when performing a later FK check in the same transaction. For example, in the same connection/transaction, the following paradigm fails often: insert into Employee (id) values (default) {generatedEmployeeId} = values identity_val_local() insert into Employer (id) values (default) {generatedEmployerId} = values identity_val_local() insert into EMPLOYER_EMPLOYEE (EMPER_ID, EMPEE_ID) values ( {generatedEmployerId}, {generatedEmployeeId} ) this last insert fails with an FK constraint violation. This happens whether we make the "values identity_val_local()" call seperately or whether we use getGeneratedKeys(). > DerbyDialect javadoc > -------------------- > > Key: HHH-1915 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1915 > Project: Hibernate3 > Type: Improvement > Components: documentation > Versions: 3.1.2 > Environment: Hibernate 3.1.2, Derby 10.1.2.1 > Reporter: Brian Bonner > > > Hibernate 3.1.2's DerbyDialect seems to work around some issues in Derby's JDBC 3.0 Support, but it's not clearly documented in the Javadoc why it is the case. > For example: > Derby does support Identity columns (http://db.apache.org/derby/docs/10.1/ref/rrefidentityvallocal.html) and it looks like the Dialect includes this, but then it uses the TableHiLoGenerator instead of the IdentityGenerator. > I assume it's to work around this problem: > http://forum.hibernate.org/viewtopic.php?t=951233&highlight=derby+native > but I can't say for certain. > I've created a JIRA on Derby: https://issues.apache.org/jira/browse/DERBY-1518 for the preparedStatement issue highlighted here, with the assumption that this is the reason. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
