Get Customers with more than one address

Here's a simple SQL statement that I've used to help me resolve some of our issues be it customer, vendor or item master files:

Select custnmbr, Count(ADRSCODE) As AddressCount
From RM00102
Group By custnmbr
Having Count(ADRSCODE) > 1

or if you want detail use this

Select *
From RM00102
Inner Join (
Select CUSTNMBR, Count(ADRSCODE) As AddressCount
From RM00102
Group By CUSTNMBR
Having Count(ADRSCODE) > 1
) As A
On RM00102.CUSTNMBR = A.CUSTNMBR
