null is query's 2003 access (1 Viewer)

one more thing. in the query design window, for an update query, you can enter criterias. what if your criteria is an empty (or null) value. i tried just using Is Null but it doesnt replace the old values. (ie, if value = "N/A" or null value, change to 99)

Criteria should read something like this: "N/A" or Is Null or " "
You'll probably find that the values aren't actually Null, just blank.

yeah, ive tried that. it doesnt seem to work

 

[mattkorguk]

What results do you get if change it to a select query and have the criteria as Is Null?
Just try each value on it's own, and check results. You've probably tried that too though?!

Can you post the actual query you're currently using? (From SQL view of course

In the updateto code
=IIf(Isnull([fieldname]) OR [fieldname] =" " OR [fieldname]="N/A",99,[Fieldname])
