  • 分页Sql语句

    第一种 Top剔除法。去除Top (pageIndex-1)*PageSize

    SELECT  TOP 10* FROM dbo.SBD_EXCHANGE_BILL
    WHERE EB_ID NOT IN (SELECT TOP (10*1) EB_ID FROM dbo.SBD_EXCHANGE_BILL ORDER BY EB_ID)

    第二种 Max剔除法 。去除 小于  Max(PageIndex-1)*pageSize

    SELECT TOP 10 * FROM dbo.SBD_EXCHANGE_BILL
    WHERE EB_ID >(SELECT MAX(EB_ID)
    FROM (SELECT TOP (10*2) EB_ID FROM dbo.SBD_EXCHANGE_BILL ORDER BY EB_ID) AS T )

    第三种方法 游标法(来自网络)
