SQL Port usage report per device

Hi

I created this basic SQL and published it via report writer for UDT

select n.Caption, u.PortCount, u.ActivePortCount, u.PortCount - u.ActivePortCount as [UnusedPorts], ROUND((cast(u.ActivePortCount AS float)/u.PortCount) * 100, 1) as [% FreePorts] from dbo.UDT_Switch u, dbo.Nodes n
where u.NodeID = n.NodeID

Kind Regards
