select threadid from (select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads) as T where T.Pos > 100000 and T.Pos < 100030

===========================================

如果里面的這個(gè)表cs_threads數(shù)據(jù)量超大，比如，幾億條記錄，那這個(gè)方法應(yīng)該是有問(wèn)題的

因?yàn)椋瑂elect threadid from ( select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads ) as T where T.Pos > 100000 and T.Pos < 100030 這個(gè)語(yǔ)句是把select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads它全部取出來(lái)，然后在SQL的外面進(jìn)行分頁(yè)的，沒(méi)在SQL2005上測(cè)試過(guò)，因?yàn)樵仍贠RACLE上這樣的寫法是不好的，ORACLE中這樣寫比較好：select threadid from ( select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads a where a.pos<100030 ) as T where T.Pos > 100000
