Question

I’m not good with the old JOIN statements and looking for a little friendly help. I have two tables, lets say table Employee:

   LastName DepartmentID
Rafferty    31
Jones   33
Steinberg   33
Robinson    34
Smith   34
John    NULL

and table Department:

DepartmentID    DepartmentName
31  Sales
33  Engineering
34  Clerical
35  Marketing

if I want to return results where DepartmentID=31 AND only results where Employee.DepartmentID = Department.DepartmentID, so that the returned result would look like this:

Employee.LastName   Employee.DepartmentID   Department.DepartmentName
Rafferty    31  Sales

(we can drop one of the DepartmentID’s since they are the same) – what is the SQL statement that will accomplish that?

Thanks

Answer 1

SELECT e.LastName, e.DepartmentID, d.DepartmentName
FROM Employee e
INNER JOIN Department d ON d.DepartmentID = e.DepartmentID
WHERE d.DepartmentID = 31
