Re: [eclipselink-users] ManyToMany join table with an id
|
It depends on how you want the id assigned. If the database assigns the
value through an IDENTITY column, or trigger, then it will be fine. If you
want JPA or your application to assign the id, then you need to create a
class for the join table.
You might also be able to assign the id, using custom SQL in the EclipseLink
mapping using a DescriptorCustomizer (mapping.setInsertSQLString()).
