I need all vouchers in maximum of update number.

create table #temp (_Type varchar(20),_Voucher varchar(20),_Update int)
insert into #temp (_Type,_Voucher,_Update) values ('AAA','1001',1), ('AAA','1001',2), ('AAA','1001',3),
('BBB','1001',1), ('BBB','1001',2), ('BBB','1001',3),('CCC','1001',1), ('CCC','1001',2), ('CCC','1001',3)

drop table #temp

Hi @Mohamed Farook

If I understand correctly, you can try this query.

select * from   
  (select *,max(_Update)over(partition by _Type) as maximum from #temp) as t  
where _Update = maximum;
