MySQL if previous row value is greater than current row value
<p>I have a table with 2 columns: date (date) and value(int).  How can I write a query to output the date and either 'Up', 'Down', or 'Same' by comparing the previous date's value to the current date's value.  (e.g. if 12/01/2016 has a value of 100 and 12/02/2016 has a value of 200 then the output should be 12/02/2016 Up.</p>
