JPA/Hibernate maximum number of joins?

Question

Is there a limit to the number of joins permitted in a JPA/Hibernate query?

Answer 1

Are you aliasing all of your inner joins? And using those aliases? I have seen some really strange behavior with Hibernate when you try and use implicit aliasing in the SELECT clause to do stuff like this (extremely simplified example):

select p.address.state from person p

But if you explicitly declare all your aliases it works just fine. Like this:

select s from person p join p.address a join a.state s

... or even this:

select s from person p join p.address.state s
