title: phpMyAdmin: MySQL Error 1062 - Duplicate entry
body: <p>I connect with user "root" onto my database "test" which I host locally for development. Among others I have the table "ratingcomment". For some reason when I click on the table "ratingcomment" phpMyAdmin shows me the following error:</p>
  
  <pre><code>Fehler
  
      SQL-Befehl: 
  
      INSERT INTO  `phpmyadmin`.`pma_history` (
  
      `username` ,
       `db` ,
       `table` ,
       `timevalue` ,
       `sqlquery`
      )
      VALUES (
      'root',  'test',  'ratingcomment', NOW( ) ,  'SELECT * FROM `ratingcomment`'
      )
      MySQL meldet: 
  
      #1062 - Duplicate entry '838' for key 'PRIMARY'
  </code></pre>
  
  <p>I used google to finde out the following </p>
  
  <pre><code>"This indicates that you have a UNIQUE or PRIMARY index on a table, and there is a duplicate value someone on one of the values in one of these indexes."
  </code></pre>
  
  <p>But I still dont quite understand the error! I use a primary Key, which auto-increments for all of my tables, so there actually shouldnt be a problem with the table. I had another table named "rating" which had a column "comment". Can it be, that this causes problems?</p>
