Sql server 2008 比较sql server中的下一行

我有下表的场景

1列名称：操作名称='SEEDER'，下一行操作名称='AUSEAL'表示

2在下表中，我需要再添加一个列名Process_Time应该是AUSEAL的timestamp2-SEEDER的timestamp2应该显示为Process_Time

3当操作名称“SEEDER”和“AUSEAL”相继出现时，我们只需计算进程时间，否则进程时间应为“0”

下表的Select语句为：

select * from (
    select
        ROW_NUMBER() over(Order by timestamp2) ROW ,*
   from [dbo].[HIST_ACTIVITY_LOG3] where serial_no ='WCC1S8530252') t 



    Row   Serialno     timestamp2   Route_name      Operation_Name    WorkStat  Dis_Name host_Name

您可以在外部应用程序中获取下一个值

选择H1.Serialno， H1.2， H1.路线名称， H1.U操作名称， isnulldatediffsecond，H1.timestamp2，LeadH.timestamp2，0为TimeStampDiffSec 从历史活动日志3中取H1 外敷 选择top1 H2.2 来自历史活动日志3，作为H2 其中H2.Operation_Name='AUSEAL'和 H1.u操作名称=‘播种机’和 H2.timestamp2>H1.timestamp2 按H2.2订购 如铅 结果:
