[code]---------Table1-----------
declare @table1 table(A varchar(10), B varchar(10))

insert @table1
select '1', '10' union all
select '2', '11' union all
select '3', '12' union all
select '4', '13' union all
select '5', '14' union all
select '6', '15'

----------- Table2-----
declare @table2 table(C varchar(10), D varchar(10))

insert @table2
select '1','10' union all
select '2','11' union all
select '2','12' union all
select '2','13' union all
select '3','14' union all
select '3','15' union all
select '4','13' union all
select '4','19' union all
select '4','20' union all
select '4','21' union all
select '5','15' union all
select '5','16' union all
select '6','15'

select
t1.A,
t1.B,
case when t2.C is null then 'NO' else 'YES' end as Result
from @table1 as t1
left join @table2 as t2 on t1.A = t2.C and t1.B = t2.D[/code]
