Batch updates in JPA (Toplink)

问题

Is there any way if executing batch updates (EntityManager persist() or merge()) using JPA Toplink?

回答1:

If you want to do a batch update, you can create a Query (either JPQL or Native SQL) that performs the update using the EntityManager, and then call executeUpdate on that query.
