Question : Union Query duplicates

SQL Server 2008

 I have a union query of names and email addresses.

There is also a column of MemberType

On one side of the union the Membertype is 1 on the other side, it is 2.

The results will contain duplicate email addresses.  

I need to alter the query so that if a duplicate email exists then we choose the MemberType of 1 before we choose the MemberType of 2, thus ignoring MemberType 2 if a MemberType 1 exists.

Thanks

Answer : Union Query duplicates

SELECT name, MIN(MemberType) MemberType
FROM
(
  SELECT name, MemberType FROM tbl1
  UNION ALL
  SELECT name, MemberType FROM tbl2
) t
GROUP BY name ;
