Hi ,


This allows children to be deleted when the parent is deleted.
so do I need to set the attribute value cascade is true on to the Parent Pojo or is it on to the Chile POJO ?

Thanks in advance.

You need to put the cascade in the parent class.

Hi,

I would say, it depends on the relationship existing between Parent and Child objects.
To elaborate more, consider below examples:

Scenario 1:

Parent has 1-to-many with Child
Child has many-to-1 with Parent

We can, as specified in earlier post, use cascade on Parent hbm to save/delete Child.

Scenario 2:

Only Child has many-to-1 with Parent: On DB side, Child table would have Parent_ID as F.K.
In this case, Child hbm would have cascade which will
On insertion: Insert in Parent and then in Child tables.
On Deletion: Delete from Child and then from Parent tables.
