There is an UNPIVOT operator in SQL 2005. But it's mainly syntactic
sugar, and you can easily unpivot without it:
SELECT year, value = CASE year WHEN 2001 THEN [2001]
WHEN 2002 THEN [2002]
...
END
FROM tbl
CROSS JOIN (SELECT 2001 UNION ALL
SELECT 2002 UNION ALL
...) AS year
My thought, though, was that you would redesign the table on a
permanent basis.
