I use this syntax in my where clauses rather than case statements:
WHERE
((@StartDate IS NOT NULL AND StartDate >= @StartDate)
OR
(@StartDate IS NULL))
AND ((@EndDate IS NOT NULL AND EndDate <= @EndDate)
OR
(@EndDate IS NULL))
You too might want to read that article from Gail. This type of approach can lead to really awful performance.
