CREATE TABLE [dbo].[CustomerTrack](
 [ID] [int] IDENTITY(1,1) NOT NULL,
 [CustomerID] [uniqueidentifier] NULL,
 [Channel] [int] NULL,
 [OrderIndex] [int] NULL,
 [Value] [nvarchar](50) NULL,
 CONSTRAINT [PK_CustomerTrack] PRIMARY KEY CLUSTERED

上表增删改之后，下述脚本更新orderindex

with r_SomeTable
as
(
select *

, row_number() over(partition by IDCol order by ValueCol) as rnk
from SomeTable
)
update r_SomeTable
set RANKCol = rnk
