title: We used to send parameters to our WMS geoserver SQLViews by the viewparams field. But WMTS doesn't have this field
body: <p><code>Geoserver</code> offers to use <a href="https://docs.geoserver.org/stable/en/user/data/database/sqlview.html" rel="nofollow noreferrer">parametrized SQL views</a>. Parameters are put in a <em>viewparams</em> field and it receives them as parameters for the SQL request.</p>
  
  <p>However, we discovered that tiled WMS (WMTS) doesn't have that <em>viewparams</em> field.<br>
  How can we send our parameters ?</p>
  
  <p>Regards,</p>
