I have 2 tables that are exactally the same.

Table 1 - Is named LIVE
Table 2 - Is name EOM (End of Month)

The 2 tables have these fields
MEMBER
STREET

I want to build a query that will return any member who has changed their address (ex: member's eom address is "123 main st", and now their live address is "345 apple st")

But I do not want to display any addresses that are different because that member wasn't a member last month (not in the eom table)

Note: Member Numbers Never Change, only addresses will.

Thanks in advance for any help/suggestions.

SELECT * FROM (
SELECT MEMBER, STREET FROM LIVE
UNION SELECT MEMBER, STREET FROM LIVE) as a
GROUP BY MEMBER
HAVING COUNT(*) > 1
