General - Do you know every object name should be owned by dbo?

The reason is that you avoid ownership chain problems. Where Mary owns an object, Fred can read the object and then he creates a proc and he gives permission to Tom to execute. But Tom cannot because there is a product chain of ownership.

CREATE PROCEDURE [Adam Cogan].[Sales by Year]

ON Orders.OrderID = "vwOrderSubTotals".OrderID

WHERE Orders.ShippedDate Between @Beginning_Date And @Ending_Date
