Answer 1

hi guys
this solution is my answer :

With CTE1 as  
(select *,ROW_NUMBER() over (partition by [name] order by id) as rn1 from @TAB )
,CTE2 as
(select *,ROW_NUMBER() over (partition by [work] order by id desc) as rn2 from @TAB )
select C1.Id,C1.[name],ISNULL(C2.[work],'') from CTE1 C1 left join CTE2 C2
on C1.rn1=1 and C2.rn2=1 and C1.[name]=C2.[name]
where C1.rn1=1
order by C1.id
---------OUPUT------------
--1 sina graphist
--2 ali programmer
--3 jack
