title: SQL - Update table values from values in another table
body: <p>I have a select statement that is showing me all the data from table original every time it does not match the values on table real_values.</p>
  
  <p>So every time it does not match, instead of showing me which routes have the wrong values for capacity, I would like the query to update it with the correct values.</p>
  
  <p>Here is a shorter version to use as an example:
  <a href="http://sqlfiddle.com/#!4/6a904/1" rel="nofollow">http://sqlfiddle.com/#!4/6a904/1</a></p>
  
  <p>Instead of being a select statement, how could I just update the values? I have tried some things I've seen online but nothing seems to work.</p>
