title: What is wrong with this?
body: <pre><code>SELECT KundeID, Kundenummer, Fornavn, Efternavn, Adresse, Postnummer, [By] 
  FROM dbo.Kundeliste
  INNER JOIN Ordreliste
  ON Ordreliste.KundeID&lt;&gt;Kundeliste.KundeID
  </code></pre>
  
  <p>I dont get the right output. I need all customers that not yet has placed an order from my customerlist</p>
