EclipseLink JPA 2.1

This page contains a summary of the major features supported in EclipseLink that implements the JPA 2.1 (JSR 338) specification requirements. The features and examples on this page do not represent a complete list. For more information, please see: the JSR 338 page.

Bulk Update

Until JPA 2.1, performing deletes or updates was not available using the Criteria API. Through the addition of CriteriaUpdate/CriteriaDelete classes, support for bulkupdate/delete queries has now been added.

Update Example

The following example will update the salary and status, of all Employees who make less than 10000$, and give them a raise.

  CriteriaUpdate<Employee> q = cb.createCriteriaUpdate(Employee.class);
  Root<Employee> emp = q.from(Employee.class);
  .set(e.get(Employee_.salary),, 1.1f))
  .set(e.get(Employee_.status), "full_time")
  .where(, 10000));

The following Java Persistence query language update statement is equivalent.

  UPDATE Employee e SET e.salary = e.salary * 1.1, e.status = "full_time" WHERE e.salary < 10000

Delete Example

  CriteriaDelete<Customer> q = cb.createCriteriaDelete(Customer.class);
  Root<Customer> c = q.from(Customer.class);
  q.where(cb.equal(c.get(Customer_.status), "inactive"),

The following Java Persistence query language delete statement is equivalent.

  DELETE FROM Customer c
    WHERE c.status = 'inactive'
    AND c.orders IS EMPTY
