I also saw this post. Howeve, if we modify it in the following way: DELETE T1 FROM MyTable T1, MyTable T2 WHERE T1.dupField = T2.dupField AND T1.dupField2=T2.dupField2 AND T1.uniqueField > T2.uniqueField And if dupField2 is NULL, then it does not work. Any suggestions Great!

I also saw this post. Howeve, if we modify it in the following way:

DELETE T1
FROM MyTable T1, MyTable T2
WHERE T1.dupField = T2.dupField AND T1.dupField2=T2.dupField2
AND T1.uniqueField > T2.uniqueField

And if dupField2 is NULL, then it does not work. Any suggestions
