[regression] Columns named "to_date" no longer work
---------------------------------------------------

                 Key: HHH-5128
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5128
             Project: Hibernate Core
          Issue Type: Bug
    Affects Versions: 3.5.1
         Environment: Database = Oracle 10g
            Reporter: Ramon Casha


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.
