但是，在SQL SERVER 2005 之前，SQL SERVER 2000 并沒有提供這個直接的函數(shù)供我們使用，同樣 ACCESS 也是如此。 下面我們分2種情況，來寫出數(shù)據(jù)排名的實現(xiàn)過程。測試數(shù)據(jù)如下：
排名后的結(jié)果如下：
Access
復(fù)制代碼 代碼如下:
select name, score, (select iif(isnull(sum(1)), 1, sum(1) + 1) from score_rank where score > a.score) as rank from score_rank a order by score desc
sqlserver
復(fù)制代碼 代碼如下:
select name, score, (select ISNULL(sum(1),0) + 1 from score_rank where score > a.score) as rank from score_rank a order by score desc
對于 SQL SERVER 2005 及更高版本
復(fù)制代碼 代碼如下:
SELECT name, score, RANK() OVER (ORDER BY score DESC) AS [rank], DENSE_RANK() OVER (ORDER BY score DESC) AS [rank1], NTILE(4) OVER(ORDER BY score DESC) AS [rank2] FROM score_rank ORDER BY score DESC;
