V_EMP  XX_EMP%ROWTYPE;
 
 
BEGIN
V_SQL := 'SELECT * FROM XX_EMP WHERE DEPTNO = :DEPARTMENT';
 
    OPEN C1 FOR V_SQL USING 10;
 
    LOOP
    FETCH C1 INTO V_EMP;
    EXIT WHEN C1%NOTFOUND;
    dbms_output.put_line ('Employee Name: '||V_EMP.ENAME||' | Salary : '||V_EMP.SAL  );
    END LOOP;
 
    CLOSE C1;
END;
