title: Update a SavedQuery (View) from the SDK
body: <p>I am trying to change all the Business Unit references I got after importing a solution to the ones in the Acceptance environment.</p>
  
  <pre class="lang-cs prettyprint-override"><code>QueryExpression ViewQuery = new QueryExpression("savedquery");
  String[] viewArrayFields = { "name", "fetchxml" };
  
  ViewQuery.ColumnSet = new ColumnSet(viewArrayFields);
  
  
  ViewQuery.PageInfo = new PagingInfo();
  ViewQuery.PageInfo.Count = 5000;
  ViewQuery.PageInfo.PageNumber = 1;
  ViewQuery.PageInfo.ReturnTotalRecordCount = true;
  
  EntityCollection retrievedViews = service.RetrieveMultiple(ViewQuery);

      { }
      else

          for (int i = 0; i &lt; guidDictionnary.Count; i++)

              var entry = guidDictionnary.ElementAt(i);

              }
  
          }
      }
  
  }
  Console.WriteLine("{0} values to be updated. {1} shall be mapped to acceptance, {2} to prod. Total = {3} : {4}", oldValues, accValuesUpdated, prodValuesUpdated, total, retrievedViews.Entities.Count);

  <p>I see that the new value is corrected, but it does not get saved. I get no error while updating the record and publishing the changes in CRM does not help.</p>
  
  <p>Any hint?</p>
