I have a table where multiple records have been duplicated and I need to return results based on two criteria, the Name of the person and the Street Address Line 1. I am not sure if the query is accurate because it returns the same results as when I just use one criteria:

Select
tName,
tCity,
tPhone,
tStreetLine1
from
tblObjectType20005
Group by
tName,
tCity,
tPhone,
tStreetLine1
Having(COUNT(tName)>1) and (COUNT(tStreetLine1)>1)

The code you posted does not parse - the where condition is not complete. So not quite clear to me what the requirement is. Would this do it?

SELECT
	tName,
	tCity,
	tPhone,
	tStreetLine1
FROM
	tblObjectType20005 a
WHERE
	EXISTS
	( 
		SELECT 1 FROM tblObjectType20005 b WHERE a.tName = b.tName AND a.tStreetLine1 = b.tStreetLine1
		HAVING COUNT(*) > 1
	)

I realized that I had posted the incorrect code and have corrected my errors. Thank you for the quick response as the query you have posted is successful.
