Question

I have Statement A and Statement B.

Statement A returns 5 records and statement B returns 1 record.

Statement A

    SELECT DISTINCT    
    Outlet.cCode,
    Employee.cEmployeeNumber,
    FROM  Outlet 
    INNER JOIN Employee ON EmployeeOutlet.iEmployee = Employee.iID 
    WHERE cCOde = 123

Statement B

 Select OutletCode, RSMcode, ASMcode, FMcode from Employee_Hierarchy
 Where OutletCode = 123

Now just 3 of the records from Statement A must be returned with the Employee.cEmployeeNumber is either equal to RSMcode, ASMcode or FMcode……

Now if I add the following JOIN in it will just return 1 records, how do I cater for the other 2 that are still needed?

 SELECT DISTINCT    
        Outlet.cCode,
        Employee.cEmployeeNumber,
        FROM  Outlet 
        INNER JOIN Employee ON EmployeeOutlet.iEmployee = Employee.iID 
        INNER JOIN Employee_Hierarchy as EH ON EH.RSMcode = Employee.cEmployeeNumber and EH.OutletCode = Outlet.cCode
        WHERE Outlet.cCode = 123

When I add a JOIN for each RSMcode and ASMcode and FMcode it returns nothing…..

How’s this?

SELECT DISTINCT    
    Outlet.cCode,
    Employee.cEmployeeNumber,
    FROM  Outlet 
    INNER JOIN Employee ON EmployeeOutlet.iEmployee = Employee.iID 
    INNER JOIN Employee_Hierarchy as EH ON EH.OutletCode = Outlet.cCode AND (EH.RSMcode = Employee.cEmployeeNumber OR EH.ASMcode = Employee.cEmployeeNumber OR EH.FMcode = Employee.cEmployeeNumber)
WHERE Outlet.cCode = 123
