How To Name Query Output Columns?

Each column in the query output has a default name. If you don't like the default name, you can specify a new name for any column in the query output by using the AS clause. The following statement shows you a good example:

SELECT tag AS Category, YEAR(created) AS Year, 
   COUNT(*) AS Counts FROM fyi_links 
   GROUP BY tag, YEAR(created) ORDER BY COUNT(*) DESC
GO
Category   Year   Counts
