SQL from an App.Query

The easiest way to get SQL data is using Visual Query. Note that this only works, if your razor is inside 2sxc/eav. This example gets the list of files from DNN using a query like
Select Top 10 * from Files Where PortalId = [Params:PortalId]
Note that the parameter PortalId is preset to be [Portal:PortalId].


Current Portal

In this example PortalId uses the preset [Portal:PortalId]

    @{
      // Get the query and ask for the "Default" results as a dynamic List
      var query = App.Query["DnnFilesFromSql"];
      var files = AsList(query);
    }
    <ul>
      @foreach(var file in files) {
        <li>
          @file.FileName
        </li>
      }
    </ul>
