2分法分頁存儲進程劇本實例。本站提示廣大學習愛好者：（2分法分頁存儲進程劇本實例）文章只能為提供參考，不一定能成為您想要的結果。以下是2分法分頁存儲進程劇本實例正文
須要解釋的是：這個存儲進程參數比擬多，我再現實應用中又在裡面零丁寫了一個類，頁面挪用直接挪用封裝的類，辦法有許多，重要是思緒，年夜家可以參考下。
代碼修正集中在相似
if @Sort=0
set @strTmp = @strTmp + '<(select min('
else
set @strTmp = @strTmp + '>(select max('
別的94行重要是合營我本身寫的類，顯示記載條數分頁數等信息，假如不須要就去失落。
