title: SQL Update does not work. Why?
body: <p>Just a simple SQL question - Bbut i can't figure out whats wrong</p>
  
  <pre><code>"UPDATE veranstaltungen
      SET name = '$nameV', SET Datum = '$DatumV', SET beschreibung = '$beschreibungV'
   WHERE id = '$id'"
  </code></pre>
  
  <p>I want to update the table row where the id is $id. But nothing happens here?
  the variables are all correct</p>
