> Using Hibernate 3.2, I had columns named from_date and to_date - these worked without problems.
> Since upgrading to Hibernate 3.5, the column to_date no longer works. When generating SQL queries, this column is not prefixed by the table alias name. For example, Hibernate generates the following SQL:
> select 
>   amounts0_.from_date as from14_44_1_, 
>   to_date as to18_44_1_
>   --etc--
> from reg_alloc_amount amounts0_ 
> left outer join reg_alloc_amount allocamoun1_ on amounts0_.rec_link_id=allocamoun1_.alloc_amount_id 
> This gives java.sql.SQLException: ORA-00918: column ambiguously defined
> I suspect that Hibernate treats to_date as an Oracle function instead of a column.
