I've been searching for awhile now on how to remove duplicates from a
table within an Access db and have found plenty of articles on finding
or deleting duplicates. All I want to do is remove them from within an
SQL query - leaving one of the records behind of course.
I have a mailing list comprised of a union query that gets records from
two separate tables.
I want to be able to run a query that removes one (or more) of the
duplicated addresses within the query but doesn't make any
modifications to the table.
Please help! :)

I apologize if I have broken etiquette on that - I posted to both
groups as I was not sure which one was the best one to get an answer --
clearly it is this one.

Both groups are excellent for getting answers. Many people monitor them both
(and others as well). It can be irritating to spend time posting an answer
only to find later that it had already been answered in another ng.
Multiposting is generally considered poor netiquette. Much less
objectionable is crossposting, that is posting the same message to 2 or 3
groups in a single message. That way if someone answers in one group, the
answer will appear in the others.

I'm pretty sure I know everything that I can remember.
Again my apologies - I'll do it the right way next time.
OK, how 'bout this?
SELECT
FirstName,
LastName,
HomeNum,
HomeStreet
From
Table1
UNION
SELECT
FirstName,
LastName,
HomeNum,
HomeStreet
From
Table2
Where
LastName & HomeNum Not IN (
SELECT
LastName & HomeNum
From
Table1)
This should return a list inclusive of both tables but where LastName and
HomeNum are duplicated, only the choice from the first table. I generally
try to avoid using NOT In because it tends to be slow and inefficient, but
there are occasions.
HTH,

I meant yes -- I said "in this case" as I might want to change the
criteria at some point.
I believe that did it!!!! Thank you!!!!

If Brad Johnson, who lives at 123 Sycamore is in your work table and
Jane Johnson, who lives at 123 Honeysuckle is in your person table I
hope you don't want to see Jane in the results of your query.
In case I'm being too obtuse, let me put it differently:
You should not have two tables. You should have one table and an
extra field, which would be used to indicate whether the name is
personal, work or both. Really.

FWIW - Mike is absolutely right. I gave you a workaround but it doesn't
correct the real problem.

I apologise if this is a trivial question but I have appended three
tables in access and within this table, there are duplicate entries. I
have tried to set my reference number for this table to be a primary
key to ensure duplicates are no longer shown but this changes itself as
soon as the tables are all appended together. I appreciate any help you
can give me. Thanks alot.

Hi
I have a problem which I hope someone can help me with because I
really don't even know where to start with it.
I am using Access 2003. I have a delimited text file which contains
about 200,000 lines. There are only 2 fields, Role and ID. The role
field contains many duplicates, out of the 200,000 records I think
there are only 16,000 unique roles.
