Hi James,

Say I have x rows of 2 columns each.
For example, 2 rows: 'A 10:00pm' and 'A 11:00pm'.
I want to return one 'A' row with the latest time (eg. 'A 11:00pm).
I could do 'select distinct(col1) from table' and then 'select
col1, max( col2 ) where col1=row[0]'?
Is there a way to do it in one select?
Yes. Here are a bunch of different ways:
