Self join to a table

Question

I have a table like

Employee
==================
name      salary
==================
a        10000
b        20000
c        5000
d        40000

i want to get all the employee whose salary is greater than A's salary. I don't want to use any nested or sub query. It has been asked in an interview and hint was to use self join. I really can't figure out how to achieve the same.

Answer 1

select e1.* from Employee e1, Employee e2  where 
           e2.name = 'a' and
           e1.salary > e2.salary

Using self join

 select e1.* from Employee e1 join Employee e2  on 
           e2.name = 'a' and
           e1.salary > e2.salary

Answer 2

SELECT emp1.* FROM Employee emp1 JOIN Employee emp2
ON emp2.Name = 'A' and emp1.Salary > emp2.Salary
