The following query works well except when i try to add GROUP BY

    SELECT *
      FROM        tblEvents AS EVT
      WHERE        EVT.Online='1'  AND  (etc)    
      ORDER BY EVT.Date ASC, EVT.Time
        GROUP BY State

How to re format so i can aggregate for States together (groupings ordered alphabetically by State), then within each State, ordered by date

thank you!

Do you have to do a SELECT *

??

It is considered poor practice to use SELECT * in your queries..  Yes, even if you have 140 columns in your table..

Group BY should be only necessary for when you use a COUNT in SQL....  Yes, you can order the result set, but when you use GROUP BY, you are going to have list out the columns to group..

hmmm  . . .  so there's no sub-select solution to pre-sort them by State clusters?
(sounds like i mis-used the keyword GROUP, sorry)

there are probably 23 fields out of 25 that are needed in the results (it's a very details event listing spec!)

so then just several levels of ORDER BY?
State ASC, Date ASC, Time ASC
