  I am trying to create a query that will create a percentage based on 2 know column values

  I want to make a column of percentage based on
  Maxbps_In95 / Interfaces.InterfaceSpeed and
  Maxbps_Out95 / Interfaces.InterfaceSpeed
  So really I want 2 extra cloumns

  Thanks

  Here is the current query

  SET NOCOUNT OFF
  SET ROWCOUNT 0

  DECLARE @StartDate DateTime
  DECLARE @EndDate DateTime

  SET @StartDate = DATEADD(d, DATEDIFF(d, 0, DATEADD(m, -1, DATEADD(d, 1 - day(getdate()), getdate()))), 0)
  SET @EndDate = DATEADD(ms, -2,DATEADD(d, DATEDIFF(d, 0, DATEADD(d, 1 - day(getdate()), getdate())), 0))

  SELECT Interfaces.InterfaceId,
    Nodes.NodeID,
    Nodes.Caption AS NodeName,
    Nodes.VendorIcon AS Vendor_Icon,
    Interfaces.Caption AS Interface_Caption,
    Interfaces.InterfaceIcon AS Interface_Icon,
    Maxbps_In95,
    Maxbps_Out95,
    Maxbps_95,
    Interfaces.InterfaceSpeed AS Interface_Speed                               
  FROM Nodes
  INNER JOIN Interfaces ON Nodes.NodeID = Interfaces.NodeID
  INNER JOIN (
   SELECT InterfaceID,
     dbo.GetInBps95th(InterfaceID, @StartDate, @EndDate) AS Maxbps_In95,
     dbo.GetOutBps95th(InterfaceID, @StartDate, @EndDate) AS Maxbps_Out95,
     dbo.GetMaxBps95th(InterfaceID, @StartDate, @EndDate) AS Maxbps_95
   FROM InterfaceTraffic
   WHERE InterfaceTraffic.DateTime >= @StartDate AND InterfaceTraffic.DateTime <= @EndDate
   GROUP BY InterfaceID
  ) TrafficStat
  ON Interfaces.InterfaceID = TrafficStat.InterfaceID
  WHERE (1=1)  AND 
  (  (Nodes.TBU = 'TBU') AND   (Interfaces.Link_Type LIKE '%Primary%') )

  ORDER BY NodeName, Interface_Caption

  Is there some reason you can't just add two new columns with those formulas to the SELECT?
