Hi,
I have requirement to update Many-to-one relationship ,
For instance , Books belong to one author >> Book (*- 1) Author1
I need to update Book1 to point to another Author1.
I have tried using em.merge(Book) with CascadeType.MERGE but it doesnt work.
It should work.
There is no exception generated , but the data is also not updated in
database.
Can anyone explain me how to update Book1 to point to another Author.
Thanks in advance
-H
