Basically you have to solutions. Change the schema so they are they same
type so the cast is not required. Or use a pass-through query. That's listed
right next to the union query. You can't use the query builder then but
access will send exactly what you type.

What I generally do is use the query builder to build the structure and then
convert to passthrough for final touching up.

You'd have to write you're own function for this, which would slow it down.
Mind you, not really more than what it does with the cast.
