一種高效的分頁機(jī)制,設(shè)想階段,大家快來大討論拉,歡迎批判

id lt quot sybase

分頁

還只是個(gè)想法,大家看看,可不可行:

在向數(shù)據(jù)庫插入一條新的紀(jì)錄后,也就是發(fā)布一條信息后,立即對所有數(shù)據(jù)進(jìn)行一次分頁處理,取得每頁的第一個(gè)id號,如1134,1100,1080,1033,將這些id號存入數(shù)據(jù)庫或一個(gè)文本文件,在信息瀏覽頁,就通過這些id來分頁,如
第一頁
第二頁
第三頁

列出每頁信息:
sybase_query("set rowcount 20");
sybase_query("select id,title from test where id
哈哈,搞定,由于發(fā)信息的人遠(yuǎn)遠(yuǎn)少于瀏覽信息的人數(shù)(當(dāng)然對于本論壇例外),所以這樣可可大大減低服務(wù)器的負(fù)荷,不必每次瀏覽都對整個(gè)表檢索一次,對于sybase,mysql,orcal,本方法都應(yīng)很有效,因?yàn)閙ysql的limit也是要對整個(gè)表進(jìn)行檢索的
