Susan,

No, AFAIK you cannot use any constant directly in a query, even if it is
global.  you could call a function which returns a variant though.

========JC recommended making VBA's vbNull constant global in a module. That
way you can use it in a query expression. It's a terrific idea, wish I'd
thought of it. You might try that.
