> I have a following beans:

> }
>
> @Entity
> class B {
> @Id
> long id;
>
> int field2
>
> @Embedded
> A field3
> }
>
> When I trying to delete all instances of B entity from data storage by
> "delete from B" I got:
>
> 1. Query ("select" statement) for all B instances
> 2. For each instance from 1. delete statement
>
> Why this is not delete by simple "delete from B" sql statement?
