Cetin,
Many thanks - that simply change gives me the desired result.

>>Hi all,
>>I'm trying to write a routine to identify duplicate records. I have a select statement that uses certain criteria to compare each record with all the others in the table. This seems to work but foreach record that produces a match I also get a match when I get to the matched record a compare that. Is there some way to prevent this?

>>My results look something like

>>id1 id2
>>1   2
>>2   1

>>All I really want in this instance is one entry.
>>This is the select statement

>>SELECT Addresses.iid, Addresses_a.iid;
>> FROM duplicates!addresses, duplicates!addresses Addresses_a;
>> WHERE Addresses.iid <> Addresses_a.iid;
>>   AND Addresses.csurname == Addresses_a.csurname;
>>   AND Addresses.cforename == Addresses_a.cforename;
>>   AND (Addresses.caddress_1 == Addresses_a.caddress_1;
>>   OR (Addresses.cpostcode == Addresses_a.cpostcode));
>> ORDER BY Addresses.csurname, Addresses.cforename
>>

>>Many thanks in anticipation.
