I need some help putting this together. I have a database that looks like the following:
Employee (empNo, fName, lName, address, DOB, sex, position, deptNo)
Department (deptNo, deptName, mgrEmpNo)
I need to figure out how to display the total amount of employees that are managed by James Adams.
This is what I have but I think it's only going to produce '1' because I think it is saying "Count total employees who have the position manager, first names James and last name Adams.
ℑCOUNT empNo (σ position = 'manager' ∧ fName = "James" ∧ lName="Adams"(Employee))
Any Help is appreciated.
