Hi !
Sorry, if i am asking about a trivial problem.
I tried to cascade update parent/child elements, il got the message below:
SQL insert, update or delete failed (expected affected row count: 1, actual affected row count: 0). Possible causes: the row was modified or deleted by another user, or a trigger is reporting misleading row count.
I don't know if it's a facility problem, or anything else.
Thanks in advance for your help.
Code:
Department dept = session.Load(typeof(Department), 1)) as Department;
Employee emp = new Employee();
emp.DeptDepartment = dept;
emp.Name = "my name";
emp.Sex = 1;
dept.EmployeesDept.Add(emp);
session.Save(dept);
Code:
<?xml version="1.0" encoding="utf-8" ?>
