[Hibernate-JIRA] Created: (HHH-2432) Collection Mapping via "property-ref" on non-pk-column crashes

by Stefan Krinkel (JIRA)

Collection Mapping via "property-ref" on non-pk-column crashes -------------------------------------------------------------- Key: HHH-2432 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2432 Project: Hibernate3 Type: Bug Components: core Environment: 3.2.2, Sybase DB Reporter: Stefan Krinkel Hi, when using the following example, Hibernate attempts to pull a "getTownId()" on an Integer! 2 Tables, Village and Councillor. Village has a comp. ID (TownId, VillageId), Councillor uses just the TownId-Part. To accomplish that, TOWN_ID is mapped twice (first in comp.key, second as "townCode"), to be able to do a 'property-ref'. When doing an ordinary "village.getCouncillors()" there's an IllegalArgumentException which roots to BasicPropertyAccessor.java:145 public Object get(Object target) throws HibernateException { try { return method.invoke(target, null); } Here target is (Integer) townId and method is "VillageId.getTownId". <id name="id" type="integer"> <column name="COUNCILLOR_ID" /> <generator class="identity"/> </id> <property name="TOWN" type="integer" > <column name="TOWN_ID" not-null="true" /> </property> ============================================== <composite-id name="VillageId" class="Table1Id"> <key-property name="townId" type="integer"> <column name="TOWN_ID" /> </key-property> <key-property name="villageId" type="integer"> <column name="VILLAGE_ID" /> </key-property> </composite-id> <property name="townCode" type="integer" insert="false" update="false"> <column name="TOWN_ID" /> </property> <bag name="councillors" outer-join="false" inverse="false" > <key property-ref="townCode"> <column name="TOWN_ID" not-null="true" /> </key> <one-to-many class="COUNCILLOR" /> </bag> Needless to say, it's a legacy database, so wildly changing tables is out of question for me, it has to work with hibernate.

[Hibernate-JIRA] Created: (HHH-2161) hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect, sqltype = char, NUL but not NULL.

by Shutra (JIRA)

hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect, sqltype = char, NUL but not NULL. ---------------------------------------------------------------------------------------------- Key: HHH-2161 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2161 Project: Hibernate3 Type: Bug Environment: hibernate-3.2.0.cr5.jar, postgresql 8.1.x Reporter: Shutra When insert, if the sql type is char and the value is null, then the generated sql is like this: insert into table (column) values(?), then the postgresql said: insert into table(column) values(NUL) but not insert into table(column) value(NULL). Important: the sql type is character(in mapping file) and the java type is char. -- 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-2699) Workaround for bug in PostgreSQL JDBC driver

by Matt Solnit (JIRA)

Workaround for bug in PostgreSQL JDBC driver -------------------------------------------- Key: HHH-2699 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2699 Project: Hibernate3 Issue Type: Improvement Affects Versions: 3.2.3 Environment: Hibernate 3.2.3, PostgreSQL 8.2.4 (Mac OS X), JDBC driver 8.2 Build 505 (JDBC 3) Reporter: Matt Solnit The following line (103) in org/hibernate/connection/DriverManagerConnectionProvider.java: if (isolation!=null) pooled.setTransactionIsolation( isolation.intValue() ); causes an exception when using the PostgreSQL JDBC driver, because it does not allow you to change the transaction isolation level once a connection is in use. However, their implementation does not handle the fact that the isolation level is really not being changed in this case (because it is being set to the existing value). The following change would work around this issue: if ( isolation!=null && pooled.getTransactionIsolation()!=isolation.intValue() ) pooled.setTransactionIsolation( isolation.intValue() ); P.S. I know the DriverManagerConnectionProvider is not for production use, but we use it in development :-). -- 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-2353) ClassCastException thrown in org.hibernate.hql.ast.HqlSqlWalker.resolve

by James Andrews (JIRA)

ClassCastException thrown in org.hibernate.hql.ast.HqlSqlWalker.resolve ----------------------------------------------------------------------- Key: HHH-2353 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2353 Project: Hibernate3 Type: Bug Versions: 3.2.1, 3.2.0.cr4 Environment: Currently Hibernate 3.2.1, MySQL 5.0.26, Tomcat 5.5.20, Java 1.5 patch 10 Reporter: James Andrews Above error thrown when attempting to force a left join fetch in hql on a many-to-many mapping: Using 3 tables accountgroup id INTEGER PRIMARY ... accountline id INTEGER PRIMARY ... accountgroupmapping id INTEGER PRIMARY groupId INTEGER lineId INTEGER ...

But since the above is being encoded to an AJAX frontend, and the lines fields are referenced immediately, removing the left join fetch results in N+1 selects despite the fetch="join" and lazy="false" in the .hbm descriptor. -- 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-1905) Filters not working for DB2400 Dialect

I had set up a simple filter-def and filter based on the example in the documentation and although there are no error messages and I was able to retrieve the enabled filter from the session after enabling it, the filter was ignored when an HQL query was run.
