union query using query

[Souris]

May I use query inside my union query or I must use table in my union query?

For example, my I use

select MyField from myQuery1
union
select MyField from myQuery2

Both my queries have parameters

or I have to do


select MyField from MyTable1
union
select MyField from MyTable2


Your information is great appreciated,

You do not need anyone's permission to try it.
