[Hibernate-JIRA] Created: (HHH-2295) entity-name attribute's syntax not clearly documented

by Jeremy Michael Crosbie (JIRA)

entity-name attribute's syntax not clearly documented ----------------------------------------------------- Key: HHH-2295 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2295 Project: Hibernate3 Type: Bug Components: documentation Versions: 3.2.1 Environment: Windows XP/JDK 1.5/HypersonicSQL Reporter: Jeremy Michael Crosbie Priority: Minor Attachments: Group.hbm.xml Setting entity-name to a value containing a hyphen, in my case 'lender-group' causes odd behaviors seemingly only when calling get() or load(). Also in my case I am mapping a class to two different tables (attached). The first mapping has an entity name with a hyphen, the other does not. When I call load *after committing a transaction where a new entity is persisted* I get an exception (see below). The exception complains of a column called "LENDER" not existing. But once I change the entity-name to something like 'lendergroup' the problem goes away. Interestingly, the missing column complained about is the text before the hyphen, so if I name the entity 'lndr-group' it complains of a column name 'LNDR' not existing. It almost appears if this format is assuming some sort of discriminator, but the online docs are terse when it comes to describing the entity-name field. Exception: org.hibernate.exception.SQLGrammarException: could not load an entity: [lender-group#G9] at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:67) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.loader.Loader.loadEntity(Loader.java:1799) at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:47) at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:41) at org.hibernate.persister.entity.AbstractEntityPersister.load(AbstractEntityPersister.java:2730) at org.hibernate.event.def.DefaultLoadEventListener.loadFromDatasource(DefaultLoadEventListener.java:365) at org.hibernate.event.def.DefaultLoadEventListener.doLoad(DefaultLoadEventListener.java:346) at org.hibernate.event.def.DefaultLoadEventListener.load(DefaultLoadEventListener.java:123) at org.hibernate.event.def.DefaultLoadEventListener.proxyOrLoad(DefaultLoadEventListener.java:177) at org.hibernate.event.def.DefaultLoadEventListener.onLoad(DefaultLoadEventListener.java:87) at org.hibernate.impl.SessionImpl.fireLoad(SessionImpl.java:862) at org.hibernate.impl.SessionImpl.get(SessionImpl.java:799) 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.context.ThreadLocalSessionContext$TransactionProtectionWrapper.invoke(ThreadLocalSessionContext.java:301) at $Proxy0.get(Unknown Source) at com.fares.mtrac.group.GroupDaoImpl.findById(GroupDaoImpl.java:148) at com.fares.mtrac.group.GroupDaoImplTest.testFindByIdStringCompanyType(GroupDaoImplTest.java:256) 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 junit.framework.TestCase.runTest(TestCase.java:164) at junit.framework.TestCase.runBare(TestCase.java:130) 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:120) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:128) 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: java.sql.SQLException: Column not found: LENDER in statement [select lender-gro0_.group_cd as group1_48_0_, lender-gro0_.group_nm as group2_48_0_, lender-gro0_.user_nm as user3_48_0_ from lender_group_name lender-gro0_ where lender-gro0_.group_cd=?] at org.hsqldb.jdbc.Util.throwError(Unknown Source) at org.hsqldb.jdbc.jdbcPreparedStatement.<init>(Unknown Source) at org.hsqldb.jdbc.jdbcConnection.prepareStatement(Unknown Source) at org.hibernate.jdbc.AbstractBatcher.getPreparedStatement(AbstractBatcher.java:442) at org.hibernate.jdbc.AbstractBatcher.getPreparedStatement(AbstractBatcher.java:368) at org.hibernate.jdbc.AbstractBatcher.prepareQueryStatement(AbstractBatcher.java:105) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1561) at org.hibernate.loader.Loader.doQuery(Loader.java:661) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) at org.hibernate.loader.Loader.loadEntity(Loader.java:1785) ... 36 more -- 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-2088) TypeMismatchException on object equality expression from one-to-one relationship

by Salvatore Insalaco (JIRA)

TypeMismatchException on object equality expression from one-to-one relationship -------------------------------------------------------------------------------- Key: HHH-2088 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2088 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr4 Reporter: Salvatore Insalaco Suppose to have entity A with a one-to-one constrained relationship to an entity B, called bRel. The query: "from A a, B b where a.bRel = b" raises a TypeMismatchException, even if bRel and b are instances of the same entity. This happens because in BinaryLogicOperatorNode: - lhsType is org.hibernate.type.Type = org.hibernate.type.OneToOneType(B)", with getColumnSpan returning 0. - rhsType is org.hibernate.type.Type = org.hibernate.type.ManyToOneType(B)", with getColumnSpan returning 1. And it compares the two columnspans. It doesn't happen with 3.2.0.cr2. -- 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

Why is this exception thrown under these circumstances? Am I using the API in an undocumented/disallowed way? If yes, where exactly? The Hibernate API doc says, that Session.get() returns null if an object can't be found. No exception should be thrown. However, Session.get() at the end of sample code does return null as expected, if either a) Session.get() is used instead of load() some lines above (see commented line) b) the transaction and the session is isn't closed or reopened, respectively c) Session.flush() is called before the final call to Session.get() I'd like to understand why Hibernate behaves like this, which I presume is erroneous. I'm a beginner in Hibernate, but I couldn't get any help in the forum.

[Hibernate-JIRA] Created: (HHH-2575) Query results are mapped to object array incorrectly when there is column ambiguity and aliases are not used

by Mike Hoeffner (JIRA)

Query results are mapped to object array incorrectly when there is column ambiguity and aliases are not used ------------------------------------------------------------------------------------------------------------ Key: HHH-2575 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2575 Project: Hibernate3 Issue Type: Bug Components: query-sql Affects Versions: 3.2.2 Environment: Hibernate 3.2.2 + MySQL 5.0.22 + MySQL Connector/J 5.0.5. Reproduced with HSQLDB 1.8.0.7. Reporter: Mike Hoeffner Priority: Minor Attachments: ResultsNotEffectedByAliasesTest.java I had a SQL (not HQL) query that basically looked like this: select a.name, a.seq, b.name, b.seq from foo a, foo b; and I noticed that the results obtained through list() -> (Object[]) get(i) -> row[0], row[1], row[2], row[3] did not correspond to what I saw when manually running the query without Hibernate involved. row[2] always had the same values as row[0] and row[3] always had the same values as row[1]. When I tried adding aliases so that it became: select a.name as a_name, a.seq as a_seq, b.name as b_name, b.seq as b_seq from foo a, foo b; then the results matched what I expected. So having aliases in the SQL modified the results that were returned even though I was looking up the value from each column by its index / position instead of by its name / alias. Attached is a test case that will reproduce this. -- 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
