Question

I have two tables.

Employee

EmployeeID, EmployeeName, DocumentType

and

DocumentType

DocumentTypeID, DocumentType

There are Multiple Employees and Multiple DocumentTypes.

For each employee, I am trying to display which DocumentTypes do not exist.

I cant seem to do this for each EmployeeID/Employee Name.
I can only get a list of DocumentTypes that dont exist for ALL employees.

Can I do this without a cursor going through each EmployeeID?

Answer 1

EDIT Better version

select distinct e.EmployeeID, e.EmployeeName, t.DocumentTypeID, t.DocumentType
from Employee e
cross join DocumentType t
left join Employee e2 on e2.EmployeeID = e.EmployeeID and t.DocumentTypeID = e2.DocumentTypeID
where e2.EmployeeID is null

This works but doesn’t feel like the most elegant solution

select distinct e.EmployeeID, e.EmployeeName, dt.DocumentTypeID, dt.DocumentType
from Employee e
outer apply (
    select * from DocumentType t
    where not exists (
        select 1 
        from Employee e2 
        where e2.DocumentTypeID = t.DocumentTypeID 
        and e2.EmployeeID = e.EmployeeID)
) dt
