Why would you do it in the first place? Given a well-designed database,
the request does not make very much sense. But if you have a less well-
designed database, you need to do:

SELECT CASE @paramname
WHEN 'thatfield' THEN thatfield
WHEN 'thisfield' THEN thisfield
WHEN 'leftfield' THEN leftfield
END
FROM tbl
