[MS_AccessPros] Using "Nz" in place of "Is Not Null"

 

I am using Access 2007 on a Windows 7 system.

I am still unclear how to properly us the "Nz" operator.

I have this SQL which provides me with a single record without an
email address. How should I apply the "Nz" function?

SELECT DISTINCT RFEMembers.Email, "Validated Member" AS FullName, 1
AS ReadOnly, 0 AS PostOnly, 0 AS Digest
FROM RFEMembers
WHERE (((RFEMembers.Email) Is Not Null));

UNION SELECT DISTINCT RFEMembers.Email2 AS Email, "Validated Member"
AS FullName, 1 AS ReadOnly, 0 AS PostOnly, 0 AS Digest
FROM RFEMembers
WHERE (((RFEMembers.Email2) Is Not Null));

UNION SELECT DISTINCT RFEMembers.Email3 AS Email, "Validated Member"
AS FullName, 1 AS ReadOnly, 0 AS PostOnly, 0 AS Digest
FROM RFEMembers
WHERE (((RFEMembers.Email2) Is Not Null));

Many thanks,

Robin Chapple
