Query Expressions

[Andrea]

I am new to Access and trying to create a query that does the following: I have 4 fields for different phone numbers (home phone, work phone, etc) and a field for email addresses. Some phone numbers are empty and I want to show a list of my contacts who have email address but no phone numbers. Help!

In SQL view, it would look like:

WHERE EmailAddress Is Not Null AND HomePhone Is Null AND WorkPhone Is Null AND...

In design view, Is Not Null on the email field and Is Null on the phone fields, all on the same line.

wow, its that simple? i was playing around with the nulls but i was making it too complicated - using parenthesis and such. you're awesome! thanks!

It's that simple if it works.

Welcome to the site by the way!

One more question please??!!?!?
I want to display those who have email addresses and no cell phone listed but another number is listed. I have 3 other phone number fields: home phone, work phone, etc. and as long as there is a number in one or more of those - i want to display. just eliminating the ones who do not have any phone numbers listed. So I put "Is Null" in the cell phone field, "Is Not Null" in the Email field. What do I put in the other 3 phone fields?

Try

WHERE EmailAddress Is Not Null AND CellPhone Is Null AND (HomePhone Is Not Null OR WorkPhone Is Not Null OR WhateverPhone Is Not Null)

Note the parentheses, which when mixing AND & OR become important to clarify the logic. It's much simpler to do in SQL view to me, but it can be done in design view.

awesome! worked like a charm. i guess it is better to learn sql than design sometimes. you really helped me out. thank you! im just learning access - it is a really great program!
