title: Jooq INSERT on duplicate key UPDATE
body: <p>Trying to use "jooq" to work with db (MySQL).
  It looks like nice, but as sql query more complex jooq construction more obscure.</p>
  
  <p>Is anybody know what code should I write to get SQL-analog for:</p>
  
  <pre class="lang-sql prettyprint-override"><code>INSERT INTO table (field1, field2, counter) VALUES (123, abc, 10), (124, cde, 20)
  ON DUPLICATE KEY UPDATE counter = counter + VALUES(counter);
  </code></pre>
