Sequence number issue

Our system uses JPA to map classes to tables.

My question is: our system has a Customer table which has total 1114444 records and max number is 1533000. but the last number for Customer_seq in Oracle databse is 36000. Don`t match. but no unique constraint issue.

Can someone explain why? how JPA or hibernate generates next sequence value to insert into Customer table?

That depends on your id generation strategy.
