title: SQL join statement with where clause
body: <p>I have this question, from I am trying to get through. I have been trying to do this for hours, it would be really great if someone could point us in the right direction.</p>
  
  <p>This is in german so I am going to translate it in English:</p>
  
  <p>We only have problem with part (d)</p>
  
  <p>(d) Write an SQL statement that gives names of the restaurant and Ort(Place) of the restaurant that do not order any Salat.</p>
  
  <p>The expected result would be:</p>
  
  <p>Da Mafia : Göttingen<br>
  Venezia  : Kassel</p>
