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:SiteId]
Note that the parameter SiteId is preset to be [Site:Id].

Current Portal

In this example PortalId uses the preset [Site:Id] which is 24
