title: MySQL course scheduler
body: <p>So I have the following table containing the courses available for me to take:</p>
  
  <pre><code>"CREATE TABLE courses 
  (
  subject varchar(15), 
  course int,
  day varchar(15),
  timein double,
  timeout double,
  courseID int
  )";
  </code></pre>
  
  <p>For example: subject= ECON, course= 101, day= M, timein= 9.0, timeout= 10.3, courseID= 11.
  I need to find a MySQL script that will give me all possible combinations of the courses without having a time conflict.
  Thanks</p>
