You haven't received much response because your question is so vague. I think this may be what you are looking for.

Notice how I provided a table and sample data. This is something you should do in the future.

if object_id('tempdb..#Something') is not null

drop table #Something

create table #Something

(

Div_Time datetime,

Unit_id varchar(25),

Filled_time datetime

)

insert #Something

select '1/1/2013 01:00', 'Machine5', '1/1/2013 12:10' union all

select '1/1/2013 01:00', 'Machine5', '1/1/2013 12:15' union all

select '1/1/2013 01:15', 'Machine7', '1/1/2013 12:19' union all

select '1/1/2013 01:15', 'Machine7', '1/1/2013 12:19'

select distinct s1.Div_time, s1.Unit_id

from #Something s1

join #Something s2 on s1.Div_Time = s2.Div_Time and s1.Filled_time <> s2.Filled_time
