Eliminating Duplicates from a Query Access 2007

I've run a query that captures the data set I want. Now I want to eliminate
Duplicate names and retain only the unique names.

These are text fields, can I do this in the Criteria in Design View?

Many thanks.

Take a look at the Unique Values property of your query.

Under query types, there is a find duplicates query that will find those for
you. You could then delete them, move them to another table, or whatever.
 
It may be a simple modification to your query. It would help if you posted
the SQL text of your query.

Please copy and post the SQL of your query.

(Possibly unneeded instructions follow)
Open the query
Select View:Sql from the Menu
Select all the text
Copy it
Paste it into the message

IF you are talking about just the names, then you would add the DISTINCT
operator to the query. This combines records where the fields returned are
the same. So two records with all the same values get returned as just one row.

If you are using query design view to set up the query, you need to change the
Unique Values property of the query to Yes (True).

SELECT tbl_Investment_Commitments.[Investment Name],
tbl_Investment_Commitments.[Investment Type],
tbl_Investment_Commitments.[Date of Commitment]
FROM tbl_Investment_Commitments
WHERE (((tbl_Investment_Commitments.[Investment Type])="Fund") AND
((tbl_Investment_Commitments.[Date of Commitment])>#5/1/2008#));


Thanks for your reply. SQL above.

I'll try your 2nd solution for now.

This modification (adding the operator DISTINCT) to your query will combine
any rows that have the same values in the three fields you are displaying.

SELECT DISTINCT tbl_Investment_Commitments.[Investment Name],
tbl_Investment_Commitments.[Investment Type],
tbl_Investment_Commitments.[Date of Commitment]
FROM tbl_Investment_Commitments
WHERE (((tbl_Investment_Commitments.[Investment Type])="Fund") AND
((tbl_Investment_Commitments.[Date of Commitment])>#5/1/2008#));

And setting the Unique Value property does exactly that. It adds the DISTINCT
operator to the query.
