Isn't it incorrect to do a:

Code: Select all

select s.presentations from Student s;

[admin]

Why do you think it is incorrect?

[Guest]

Why do you think it is incorrect?

Because presentations is a collection. And you can't have a collection in the select list.

[admin]

You are right but this question doesn't have this option.

BTW, you can select a collection but you have to declare an identification variable for it in the from clause:

select p from Student s join s.presentations p;

[heaven]

The assumed correct answer D is in fact illegal by spec as stated above.
cq.select(student.<Presentation>get("presentations")) is in fact select of a collection (select s.presentations ...)

[admin]

You are right.

Code: Select all

cq.select(student.<Presentation>get("presentations")).distinct(true); //5

has now been changed to

Code: Select all

cq.select(presentation).distinct(true); //5

thank you for your feedback!
