My db includes two tables, Employees and Users, both with a pk of EmpNum (Autonumber in Employees; Number in Users). Users is a subset of Employees, and in the Users table, the row source for EmpNum is a query of the Employees table. I had a relationship defined with a one-to-one between the two tables, but did not have Enforce Referential Integrity or Cascade selected.
The problem is, I deleted a record out of Users, but it also automatically deleted the related Employees record. Re-creating the employee was quite the task because all related records in several other tables also disappeared. I experimented by deleting the relationship between the two tables and then deleting another user, but it still deleted the related employee. How can this be? The two tables are no longer linked, other than the Users EmpNum lookup.
