Answer to your question is
(based on the assumption MGR_NO column exists and is the manager empno)
SELECT E1.EMPNO,
E1.ENAME,
E1.JOB,
E1.SAL,
E1.DEPTNO,
TO_CHAR (E1.HIREDATE, 'MM-DD-YYYY') HIRE_DATE,
D.LOC,
E2.ENAME Manager
FROM EMP E1, EMP E2, DEPT D
WHERE E1.DEPTNO = D.DEPTNO AND E2.EMPNO = E1.MGR_NO;
