Three tables Employee, Manager, User_Account
Employee contains Employee_ID and User_Account_ID, Manager contains Employee_ID and Manager_ID, User_Account contains User_Account_ID and Password,
Results: Employee_ID, Manager_ID, User_Account_ID(For Employee), Password (For Employee), User_Account_ID(For Manager), Password (For Manager)
Whats the best way to achieve the results above?
Try this:
SELECT E.Employee_ID,
ME.Employee_ID AS Manager_ID,
E.User_Account_ID AS Employee_User_Account_ID,
(SELECT UA.Password
FROM User_Account AS UA
WHERE UA.User_Account_ID = E.User_Account_ID) AS Employee_Password,
ME.User_Account_ID AS Manager_User_Account_ID,
(SELECT UA.Password
FROM User_Account AS UA
WHERE UA.User_Account_ID = ME.User_Account_ID) AS Manager_Password
FROM Manager AS M
INNER JOIN
Employee AS ME
ON ME.Employee_ID = M.Manager_ID
RIGHT OUTER JOIN
Employee AS E
ON E.Employee_ID = M.Employee_ID;
