Put this in the criteria for the Email field in a query.
Is Null Or "" Or Like " *"
You actually need to check for 3 things to be sure. In a perfect world, you
would only have to check for the first one which is Nulls.
However it's possible to have something called a Zero Length String. This
most often happens if you import data from other data sources.
The last one is looking for just spaces in the field. It may look empty, but
spaces can be there.
I just thought of another way that would work in your situation. A valid
email address needs an @ symbol. Something like below would not only show
empty fields, but also email addresses which aren't valid!
SELECT [Employee Addresses].[E-Mail],
InStr([E-Mail],"@") AS Expr1
FROM [Employee Addresses]
WHERE InStr([E-Mail],"@")<1 ;
InStr([E-Mail],"@") would go in the Field of a query and the <1 would be in
the criteria.
