Select distinct problem

I have a table that is a set of responses to questions.  Each record is stamped with a GUID to identify each record as being part of a set.  So if I do

select distinct GUID from table1

I get a list of unique GUID's.  But I want this ordered by the field Entered (entered date/time)  I can't do this:

select distinct guid,entered from table1 order by entered

cause the sets are no longer distinct if I include 'Entered'.  How can I get the query to return data that is also not distinct like the entered date for each 'GUID distinct' record it returns?

You have to decide which date, and other data, you want to see: MIN, MAX or AVG.

For example:

SELECT guid, MAX(entered), MIN(someOtherColumn)
FROM table1
GROUP BY guid
ORDER BY guid

Thanks... I tried this:

SELECT guid, MAX(entered) from answers group by guid order by guid

I don't get an error but when I then try this:

Listbox1.AddItem rsAnswers!Entered

I get 'Item cannot be found in the collection...'  I need to return both the distinct GUID and its entered date.

You can sort on a computed column like sum, count, max

assuming that you need theresults sorted by time descending
the query would be

select guid, min(entered) as entered
from table1
group by guid
order by min(entered) desc

PS: the alias should resolve the rs issue

Yes, I mistakenly left off the alias(es):

SELECT guid, MAX(entered) AS entered, MIN(someOtherColumn) AS someOtherColumn
FROM table1
GROUP BY guid
ORDER BY guid
