here's something i might do in SQL to get what i'm looking for. the data is in
one table with one row per student and course. each student can have many
courses, each course can have many students. the objective is to get the
information related to the maximum course as identified by the course_id.
student_id
course_id
course_name
course_score
select a.student_uid ,a.course_id, a.course_name, a.course_score
from courses a
where a.course_id=
(SELECT MAX(b.course_id)
FROM courses b
WHERE b.course_id= a.course_id)
SAMPLE
last, first, student_uid, course_name, course_id, course_score
John, Smith, abc123, US History, 01, 4.0
John, Smith, abc123, Roman History, 02, 3.7
DESIRED RESULT: John, Smith, abc123, Roman History, 02, 3.7

Can you copy your straight SQL that works into your SQL view of access?
I
have had some luck copying SQL from other data sources, such as Oracle,
then pasting it in an access query SQL view. Sometimes I have to do a
little editing, but it may be worth a shot.
Also, is your data in one table with a single row for each record, or
many
tables containing pieces of the whole information? Can you post your
table(s) structure. Example:
tblExample
Name
UID
Subj
SubjID
"Glenda Wells"
<gwells@xxxxxxxxxxx To: <mso@xxxxxxxxxxxxx>

Please respond to

mso
it's a bear and something I've tried to resolve from time to time. In
straight SQL (PL/SQL) I can get the desired result by making a query
with the table listed twice, first to get the max then to get the
relationship. I can't remember what that's called...subquery? not sure.
Anyway, I was looking for something similar in Access either with SQL or
VBA. =20

I'm sorry, am stumped without being able to make additional queries to
summarize the subject, though I'm sure it can be done, and pretty sure
the subj field is causing the problem, cause when you remove it, the max
works fine.
