Hi,

Is it possible to prevent Hibernate completely from adding constraints to the database?

For application-purposes we need to delete objects manually from the database. Because this can be done ignoring the domain-structure, it would be much easier without database-level constraints, as the constraints are enforced by the domain-logic anyway.

Best regards and thanx for your help,

foreign-key="none"

but that is *definitly* not recommended to use just because "its hard to delete objects with constraints"

There are very good reasons why it should be hard ;)

Thanx for your answer, Max

The reason for this is the following: Our application allowes the deletion of huge amounts of data (more than can reside in memory), but still provides full undo/redo. Our solution: We flag the deleted data, so that it is recognised from application logic as deleted, but still can be resurected. When the app is closed, our manual deletion comes into play.

Any comments on this technique are highly appreciated :)

Greez,

that still isn't a reason for disabling constraints.
