[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2964) missing column name due to IndexNode.resolve calling queryableCollection.getIndexColumnNames()

missing column name due to IndexNode.resolve calling queryableCollection.getIndexColumnNames() ---------------------------------------------------------------------------------------------- Key: HHH-2964 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2964 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.5, 3.2.4.sp1, 3.2.4, 3.2.3, 3.2.2, 3.2.1 Environment: hibernate-core 3.2.5, mysql 5 Reporter: Kay Schubert Attachments: IndexNode.patch Declared entities: @Entity class Book { @Id long id; @OneToMany(mappedBy = "id.book") @MapKey(name = "id.stationName") private Map<String, StationBooksCounter> stationBooksCounter; } @Embeddable class StationBooksCounterPk { String stationName; @ManyToOne(optional = false) Book book; } @Entity class StationBooksCounter { @EmbeddedId StationBooksCounterPk id; int count; } HQL: "from Book b where b.stationBooksCounter['key'].count > '0'" results in that SQL: "select ... from Book book0_ where exists ( select 1 from StationBooksCounter stationboo3_ where books0_.id=stationboo3_.book_id and stationboo3_.null = 'key' and and stationboo3_.count>'0')" (statements text have been deducted from analogous queries in actual application - I didn't actually compile that simplified test case, since I'm quite sure what the problem is) The "stationboo3_.null" is caused by IndexNode.resolve calling queryableCollection.getIndexColumnNames() to resolve the index column name. Here queryableCollection is an org.hibernate.persister.collection.AbstractCollectionPersister, and getIndexColumnNames() returns the String[] indexColumnNames, containing only one null element. I changed that to AbstractCollectionPersister.getIndexColumnNames(String tableAlias). It uses indexColumnNames as well as indexFormulaTemplates to build the SQL fragment. -- 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
