My database has to store all the available departments in my company.
Some departments are sub-departments on another existing department. I've decided to solve this like this:
Departments
ID Description HeadOfDepartment ParentDepartment
ParentDepartment can be null, indicating it is a root department. If it has a parent I'll act accordingly, my question is how can I code this in Microsoft SQL?
