You have created a table based on the following data:
EmpID NUMBER (5) PRIMARY KEY
EmpName VARCHAR2 (35) NOT NULL
Salary NUMBER (9, 2) NOT NULL
Commission NUMBER (4, 2)
ManagerName VARCHAR2 (25)
ManagerID NUMBER (5)

the following SQL statements can you use to accomplish this?

Each correct answer represents a complete solution. Choose two.

A.
SELECT e.EmpName, m.ManagerName
FROM Employees e, Employeesm
WHERE e.EmpID = m.ManagerID;

B.
SELECT e.EmpName, m.ManagerName
FROM Employees e SELF JOIN Employeesm
ON e.EmpID = m.ManagerID;

C.
SELECT e.EmpName, m.ManagerName
FROM Employees e INNER JOIN Employeesm
ON e.EmpID = m.ManagerID;

D.
SELECT e.EmpName, m.ManagerName
FROM Employees e LEFT OUTER JOIN Employees m
ON e.EmpID = m.ManagerID;
