Question
Hibernate many to many relationship order by
Hi I was wondering when you have a many to many relationship in Hibernate if you can still order by a column on one of the child table.
For example, I have a client obj that has a set of addresses. Client and address have a many to many relationship, addresses are mapped on the client like this
<set name="addresses" table="client_address" cascade="all-delete-orphan
<key column="client_id" not-null="true" />
<many-to-many class="model.Address" column="address_id" unique="true" />
</set>
The mapping uses a reference table that only contains columns client_id and address_id. If I want to order the collection of addresses on the client obj based on a particular column in the address table, what do I need to do? I tried to use just the column name but I get error like
Caused by: java.sql.SQLException: Unknown column 'addresses0_.col1' in 'order clause'
That's because it is looking for the column in the client_address reference table instead of the address table.
How can I tell hibernate to look for the column in the address table?
Thanks

Have a look here: http://www.hibernate.org/1
If all else fails you might as well do the sorting in the Java code itself.
