Supposedly you are supposed to be able to limit the number of outer joins performed on a joined inheritance strategy. I'm trying to make a pattern where I can have an unlimited number of subtype tables
Pages 209-210 of the Book: Java Persistence with Hibernate, specifies that some RDBMs limit the number of tables in the outer joins, it goes on to show you how to do this with an xml mapping file using the <subclass> <join> and <join table> tags
the book then goes on to specify that Java Persistence also supports this mixed inheritance mapping strategy with annotations.
I'm using annotations, and can't seem to limit the outer joins
I've tried @Inheritance(strategy = InheritanceType. ( SINGLE_TABLE and JOINED ) on the SuperClass
I've tried specifying the @Column(table = (on the columns)
