Append Query resulting in duplicate records

[Guest]

Any thoughts on why this append query duplicates every record:

INSERT INTO [tblCandidate-Test] ( CANDIDATE, [NUMBER], AREA_CODE, [NUMBER],
DIAL_NUMBER, [NUMBER], FOLLOWUP_NUMBER, DNC )
SELECT [tblRRD Output].Name, [tblRRD Output].PhoneNumber, Left([tblRRD
Output]![PhoneNumber],3) AS AREA_CODE, Right([tblRRD Output]![PhoneNumber],7)
AS [NUMBER], [tblRRD Output].PhoneNumber, [tblRRD Output].PhoneNumber,
[tblRRD Output].PhoneNumber, [tblRRD Output].DNC
FROM [tblRRD Output], [tblCandidate-Test]
WHERE ((([tblRRD Output].DNC)=False) AND (([tblRRD Output].[Caller 1])="RP"));

Thanks

Because in your FROM you are grabbing data from two tables, one being
the table you are appending to. Remove that table and try again. It
is not necessary.

I fixed the duplicate records problem but now receive an error when I run it:

"MicrosoftOffice Access ... didn't add ... 3232 records due to validation
rule violations..."

I do not have any validation rules set in the tables. Here is my updated
query:

INSERT INTO [tblCandidate-Test] ( CANDIDATE, [NUMBER], AREA_CODE, DNC )
SELECT [tblRRD Output].Name, [tblRRD Output].PhoneNumber, Left([tblRRD
Output]!PhoneNumber,3) AS AREA_CODE, [tblRRD Output].DNC
FROM [tblRRD Output]
WHERE ((([tblRRD Output].DNC)=False) AND (([tblRRD Output].[Caller 1])="RP"));

Thanks.

This worked, Jeff. Any thoughts on why I am getting the error I posted?

Open your table in design view. Look at the settings for each field.
Do any of them have Yes in the Required setting or No in the Allow Zero
Length setting? I also noticed that you have [Number] several times in
your insert. You cannot perform an insert to the same field in an
insert query.

Hope that helps!
