Question

I only want to get dates from the current year, and the year previous. So if it’s 2011, I get dates in 2011 and dates in 2010. If it’s 2012, I get dates in 2012 and 2011.

SELECT 
   DISTINCT DATEPART(yyyy, date ) as arc_year 
FROM 
   dbo.sports 
WHERE 
   team_id = '".$id."' 
ORDER BY 
   DATEPART(yyyy, date ) DESC

Thanks in advance for any help

You want to avoid using a function on the column itself so an index can be used.

... WHERE date >= DATEADD(year,DATEDIFF(year,0,getdate()) - 1,0) 
      and date <  DATEADD(year,DATEDIFF(year,0,getdate()) + 1,0) ...
