当hh:mm从01更改为另一行Procs_ID时，任何人都可以帮我计算两行之间的时差（Procs_ID}。

Procs_ID  meter_id        date
  01      0000012         2015-10-12 09:07:22.530
  03      0000013         2015-10-12 09:11:51.733
  01      0000014         2015-10-12 09:12:38.550
  02      0000015         2015-10-12 10:38:52.923

以下是LEAD的示例，可用于SQL Server 2012 +

select
    *,
    case 
        when Procs_Id = '01' 
             and lead(Procs_ID) over (order by [date]) <> Procs_ID then datediff(mi,[date],lead([date]) over (order by [date])) 
    end as TimeDiffInMin
from YourTable
