title: MySQL: Difference between ', `, ´ and "
body: <p>When seeing SQL code on the internet and in manuals there seems to vary a lot what is used to signify strings (or at least that's what I think they do?).</p>
  
  <p>Are there any difference between using `, ´, ' or "? Are they all the same? Or do some of them have special meanings? Should some be used in certain cases and others in other cases? What is the deal here?</p>
