Hello,
You can try to create a View to filter the recoder you don't need. Please refer to the following statement:
Create table ticket
([Date] date ,[Date Stamp] date, [orginial ticket] int, [trade number] int, [status] varchar(20))
insert into ticket values
('2014-01-01', '2014-01-01' , 123, 130,'Modify'),
('2014-01-01', '2014-01-02' , 123, 140,'Cancel'),
('2014-01-03', '2014-01-03', 145, 150, 'Modify'),
('2014-01-04', '2014-01-04',160, 200, 'Cancel'),
('2014-01-05', '2014-01-05',210, 210,NULL)
go
create view v_ticket as
with cte as(
select [orginial ticket], [Date],[Date Stamp],[trade number],status,
row_number() over (partition by [orginial ticket] order by [date stamp] desc ) as rn
from ticket )
select * from cte
where rn = 1 and (status <>'Cancel' or status is null)
go
select * from v_ticket
