EXCEPT
(or MINUS
in Oracle) is the operation that returns only those values that are returned exclusively in the first subselect. By default, this removes duplicate rows. Use EXCEPT ALL
in order to retain them, and require duplicates to appear in both subqueries.
SELECT ID FROM BOOK EXCEPT ALL SELECT ID FROM AUTHOR
create.select(BOOK.ID).from(BOOK) .exceptAll( create.select(AUTHOR.ID).from(AUTHOR)) .fetch();
