Hibernate version:3.1.3

Mapping documents:

Code between sessionFactory.openSession() and session.close():no

Full stack trace of any exception that occurs:no

Name and version of the database you are using:oracle 9i

The generated SQL (show_sql=true):
update
course
where
studid=?

delete
student
where
id=?

Debug level Hibernate log excerpt:

my table for example is fellowed:
table:student
id
name

table:course
id
name
studid
(id -----studid)


I am crazy for this problem, I tried many way , but i failed.
The following is the segment of my student.hbm.xml:
<set name="courses" inverse="false" lazy="true" cascade="all">
<key column="studid" not-null="true"/>
<one-to-many class="course"/>
</set>

I deeped into hibernate source, I find the boolean marking whether the collection is deleted is alwayse false, so the sql is update, not delete.

any guy can give me a hand!!!!!!!!

try to use
cascade="all-delete-orphan"

first thank you.
I tried all-delete-orphan, but this problem still there.

in my source , code like this:
//begintranscation

Student student = new Student();
student.setId(XXXX);// this xxxx means a valid value and exist in my table student.
session.delete(student);

// commit

is any wrong in my code?

Yes, that code won't enable cascading deletes. Try this, instead:

thank you very very much!

i tried, the result is OK!
