nHibernate safe delete

Is there any way to check if it is safe to delete record from table ?

for example :

daoStudent.Delete(id);

doesn't throw exception if it开发者_运维知识库 has any child records , but I would like it to. I could take other actions like making student inactive.

I got it ,

SomeStudentRelation.HasItems()

to check if it has any child records.
