Compare two columns in same table; result in 3 column

[Trisha]

I need some assistance on how to perform the following in MS Access..

I have a query (Query A) and it contains data from two to other tables. I
need to compare the data from the two and in the 3rd column report true or
false (true = they match).

Example:

CUS_XID_CUST_ID, cExternalID, VALIDATION

If CUS_XID_CUST_ID = cExternalID then VALIDATION = TRUE ELSE FALSE

How do I place this into my query?

Thanks!

In the 3rd column of your query design grid put this
VALIDATION: IIf(CUS_XID_CUST_ID = cExternalID,True,False)

Thanks Ronald. When I put this in there it seems to be working but it is
prompting me to enter a value.

It brings up an 'Enter Parameter Value' window and is waiting or a response.

Should it not automatically populate the field?

Enter parameter value is usually because of a typing error in your
expression. Check the field names in your expression match the field names in
your table. The field that it is prompting for should be shown just above the
input box area.

Thank You. I figured it out. I was entering the conditions in the wrong
field. It is now working.
