Remove identical records from the same table

[Nicolae Fieraru]

Hi All,

I have a table with the following information: ID, Name, Address, Field4
In this table it happens to have duplicate records with identical Name and
Address but different content in Field4. I want to find how it is possible
to build a query which will remove records which have identical Name and
Address (Field4 may vary in content and I don't care which of the duplicate
records will be kept)

Regards,
Nicolae

delete a
from Table1 as a
where a.ID >
(
select min (b.ID)
from Table1 b
where b.[Name] = a.[Name]
and b.Address = a.Address
)
