Incorrect join formed when for one-to-one relationship to subclass in a mixed table/class table/subclass mapping strategy ------------------------------------------------------------------------------------------------------------------------- Key: HHH-1967 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1967 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.2.0.cr2 Environment: Hibernate 3.1/3.2 Sybase Reporter: Bill Swayze I have an inheritance hierarchy that I am trying to implement using the table per class and table per subclass mix strategy. A particular subclass (joined) has a unique foreign key one-to-one (mapped as many-to-one per documentation) association with another class. The sql joins generated are being formed with the base class table alias name and the subclass's column name resulting in invalid column name errors from the database. There doesn't appear to be anything in the code to discriminate whether the associations are to base or the subclass.
