復制代碼 代碼如下:
/*
數據庫分頁存儲過程，支持倒序和升序
參數說明：
@tablename：為搜索表名
@tablefield：為表的字段，約定為表的主鍵,
@where：為搜索表名，要顯示所有記錄請設為"1=1"
@orderby：為搜索結果排序，如order by id desc
@fieldlist：為字段列表，如userid, username
@curpage：當前頁碼
@page_record：每頁記錄條數
@Sort：排序標識（如果是倒序排，參數值為desc，為升序，參數值為asc，跟orderby參數是對應的）
結果： 返回表tablename中滿足條件where的第curpage頁的page_record條記錄，結果按orderby排序
