title: Computed column specification - minimum value?
body: <p>I have a table in SQL Server and have a column that I want to calculate the minimum value from three other columns (Vendor1, Vendor2, and Vendor3).  I have figured out how to sum the values but can't figure out how to find the minimum value- I keep getting an error that an aggregate may not appear in a computed column.  Is there a simple way to figure this out?</p>
