Given that the following method has just been executed, identify the correct statement(s).

public void updateAll() {
Customer cust = em.find(Customer.class, 1); cust.setStatus("normal");
Query q = em.createQuery( "UPDATE Customer c SET c.status = 'outstanding'");
q.executeUpdate();
System.out.println(cust.getStatus());
}


Could you explain why this answer is wrong

cust.getStatus() will return "outstanding".

As the explanation says, "Bulk updates are not reflected in the existing persistence context. So it will return "normal"."

You are going directly to the database and updating the values. These changes will not be reflected in the loaded entities until you refresh them.

HTH,

I think the 2nd(correct) variant is somehow misleading. The status will be updated, that is clear,
but which update we are talking about, there are two updates? In memory(by cust.setStatus("normal")) or in database(by bulk update).

I think it should be : "their status will be updated in database as well."

The option has been updated to make it clear that it is talking about the bulk update.
thank you for your feedback!
