title: I need help with a MySQL query
body: <pre><code>I have two tables - `employee` and `department`. 
  
  1. `employee` table contains column id,employee name and dept_id
  2. `department` table contains column id, department name.
  
  I need exact department name which contains 
  
  1. maximum employee and 
  2. no employee
  </code></pre>
  
  <p>Edited: </p>
  
  <pre><code>Apologizing for bad grammar, here is the example for above two questions what i need.
  1. for eg: if two department contains same number of employees, i need to show both department not single by limit.
  2. for eg: if more than one department contains 0 employees, i must show those departments particularly.
