I have a table in DB as below.It accessing through JAVA(JPA)

ID  | Name  | Parent_id
1   | Ann   | NULL
2   | Mary  | 1
3   | John  | 2
4   | Joshep| 2
5   | Peter | NULL
6   | Jeni  |5


Here Parent id refers ID of same table. if I remove any data ,all the decedents data all also will be removed.(Used ON CASCADE DELETE). For example if Name -Ann,ID-1 is removed, IDs 2,3,4 also getting removed. ON CASCADE DELETE doesn't count rows affected implicitly. Appreciate if you could anyone suggest the way to count the affected rows?

mysql hibernate jpa sql-delete cascade

What I have tried:

Query query=entityManager.createQuery("DELETE FROM Table e WHERE e.id = :id ");
                           query.setParameter("id", 1);
           int count=query.executeUpdate();


here count always remains 1, even it removed reference records as well!

This is what MS says about it:
Quote:
This executeUpdate method is specified by the executeUpdate method in the java.sql.Statement interface.

If executing a stored procedure results in an update count that is greater than one, or that generates more than one result set, use the execute method to execute the stored procedure.

I don't know what the sum of your components amounts to.
