I did it but it returns 4,4,3. So the answer was wrong!

set ansi_padding on;

go

create table #q (v varchar(5) );

go

insert into #q

select 'ABC' UNION ALL

select 'ABC ' UNION ALL

select 'ABC ' UNION ALL

select 'ABC '

select * from #q

select COUNT(*) from #q where v = 'ABC';

select COUNT(*) from #q where v = 'ABC ';

select COUNT(*) from #q where v LIKE 'ABC ';

drop table #q

go
