What is the basic difference between when we use native and increment types id generator in hibernate.
As i was having a entity, in which the generator was previuosly native, but then changed it to incremental for some time, it was working properly. But just yesterday, when i changed in to native again, the insertion is failing saying Contraint Violation.
I have index set up in the id field, which is auto generated.
Am i missing something here.
Thanks

Native means Your generator will use identity or sequence columns according to what your current database support.
A generator class is used to generate an ID for an object, which is going to be inserted in the database as a primary key. The ID is a unique identifier for the objects of the persistent class. We can use any generator classes in our application as per our requirements.
Native is generated by DB - if DB do it. Increment - generates by hibernate that are unique only when no other process is inserting data into the same table.
