Use Query to get CSV Data from a File Configured in Settings

#5 Use App Query to get SQL Data

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].

Requirements

2sxc 06.05

Resources

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>
      }
