Re: Query/400 problem

As of V4R4, you can use SQL to do this:
select opt, maxdate from (select "option", max("date") from file group by
"option")
as temp (opt, maxdate)
group by opt, maxdate
Of course the words OPTION,  DATE are SQL reserved, so you have to enclose
them

We have a simple file holding three fields:

Option (10A), User (10A), Date (10L)

Eg:

Option User Date
A           Joe   2000-10-01
A           Pete  2000-09-30
A           Joe   2000-09-20
B           Brian 2000-09-29
C           Judy  2000-09-30
C           Liz   2000-01-07
C           Joe   1999-12-22

I want to write a query that will show me the last time an option was used,
no matter who by, resulting in:

A           2000-10-01
B           2000-09-29
C           2000-09-30
