> Trying to migrate a rather large app from Hibernate 2.1 to Hibernate, we face a blocking problem. With Hibernate 3, some of our queries generate invalid SQL. I found in the forum that this problem has been noticed by someone else (but no answer) :
> http://forum.hibernate.org/viewtopic.php?t=963196&highlight=join+ora00904
> We manage to reproduce the problem with the following query. With Hibernate 2, mixing explicit and implicit joins produced an SQL query with all "theta style" joins at the end of the query. In Hibernate 3, ANSI and "theta style" are mixed, which Oracle doesn't like.
