I constantly bump up against this issue and am looking for a good
solution. I want a query that will return multiple rows, but only one
row per unique identifier in one field.
For instance, if I have the following table:
Name | Food | Eat_Date
Bob | Hot Dog | 2005-06-25
Jan | Pizza | 2005-06-27
Jim | Salad | 2005-05-25
Bob | Soup | 2005-06-03
Ann | Toast | 2005-06-13
Jim | Pizza | 2005-06-28
I want to be able to pull the most recent food by each name without
running multiple queries. I need a query that would give the results:
Bob | Hot Dog | 2005-06-25
Jan | Pizza | 2005-06-27
Ann | Toast | 2005-06-13
Jim | Pizza | 2005-06-28
Anyone have ideas of how to do this in one query?
Thanks,
Seth
