title: Find the name of the employees, whose names are same but salary are different
body: <p>I have an 'employee' table with</p>
  
  <pre><code>create table employee
  (
    e_number int,
    e_name varchar(20),
    salary money,
    hire_date date
  )
  </code></pre>
  
  <p>Now I want to display only the name of the employees who have the same name but different salary.</p>
  
  <p>I tried <code>select e_name,count(*) from employee  group by e_name having count(*)&gt;1;</code>
  but cannot combine it with "the same salary" section. Any help?</p>
