SQL performance: WHERE vs WHERE(ROW_NUMBER)

Question

I want get n-th to m-th records in a table, what\'s best choice in 2 below solutions:

Solution 1:

    SELECT * FROM Table WHERE ID >= n AND ID <         


        

Answer 1

The 2nd answer is your best choice. It takes into account the fact that you could have holes in your ID column. I'd rewrite it as a CTE though instead of a subquery...

;WITH MyCTE AS
(SELECT  *,  
         ROW_NUMBER() OVER (ORDER BY ID) AS row  
FROM     Table)
SELECT   *
FROM     MyCTE
WHERE    row >= @start 
         AND row <= @end
