I am trying to execute a delete statement on a table with a where clause that requires Hibernate to create a join.

If I execute a select with the same where the query is generated correctly.

Here are the working select and the non-working delete statements:

Code:
entityManager.createQuery("select dodm from DatabaseObjectDataMapping dodm where dodm.databaseObjectDataMappingPK.databaseObjectData.task.taskId = ?1")
      .setParameter(1, getTaskId())
      .getResultList();
entityManager.createQuery("delete DatabaseObjectDataMapping dodm where dodm.databaseObjectDataMappingPK.databaseObjectData.task.taskId = ?1")
      .setParameter(1, getTaskId())
      .executeUpdate();


Here is the output (showsql) of the two statements:

Code:
Hibernate:
    /* select
        dodm
    from
        DatabaseObjectDataMapping dodm
    where
        dodm.databaseObjectDataMappingPK.databaseObjectData.task.taskId = ?1 */ select
            databaseob0_.COLUMN_NAME as COLUMN1_89_,
            databaseob0_.DATABASE_OBJECT_DATA_ID as DATABASE4_89_,
            databaseob0_.COLUMN_MAPPING as COLUMN2_89_,
            databaseob0_.USE_SOURCE as USE3_89_
        from
            database_object_data_mapping databaseob0_,
            database_object_data databaseob1_
        where
            databaseob0_.DATABASE_OBJECT_DATA_ID=databaseob1_.DATABASE_OBJECT_DATA_ID
            and databaseob1_.TASK_ID=?
Hibernate:
    delete
    from
        database_object_data_mapping,
        database_object_data databaseob1_
    where
        TASK_ID=?
16:57:08 WARN  JDBCExceptionReporter - SQL Error: 933, SQLState: 42000
16:57:08 ERROR JDBCExceptionReporter - ORA-00933: SQL command not properly ended


The delete statement was supposed to be generated like so:

Code:
delete from
(select
            dodm.COLUMN_NAME as COLUMN1_89_,
            dodm.DATABASE_OBJECT_DATA_ID as DATABASE4_89_,
            dodm.COLUMN_MAPPING as COLUMN2_89_,
            dodm.USE_SOURCE as USE3_89_
        from
            database_object_data_mapping dodm,
            database_object_data dod
        where
            dodm.DATABASE_OBJECT_DATA_ID=dod.DATABASE_OBJECT_DATA_ID
            and dod.TASK_ID=1)


Hibernate version:

Hibernate Annotations 3.3.1.GA
Hibernate 3.2.6.GA
Hibernate EntityManager 3.3.2.GA

This is debug level log of starting with the execution of the select statement and than the delete statement:

Should I post a bug on JIRA?

Hi, pls clarify, maybe I'm missing something: you executed 2 queries separately - one select and one delete - and you expect Hibernate to run them as a single query?

No... I'm sorry if I wasn't clear.

The delete statement is the problem.

I wrote the select statement in order to show that when I execute a select statement, Hibernate knows how to create the joins needed to fetch the correct results.

When I execute a delete, Hibernate for some reason does not create the correct delete statement with joins as expected and shown above.

I am using Oracle 9 and "org.hibernate.dialect.OracleDialect" as the dialect.

Yes. I also tried it.
I think that this is not the problem because the dialect is working properly in the select statement generation.

yeah, I'm not an official authority, but try posting a JIRA issue, or at least search the JIRA for anything similar.
