Union works if the data type is compatible and the number and order of the field must be identical.
e.g combining result from these 2 query:
select a, b, c from tablex
select x,y,z from tablez

Or even if SQL can coerce the data types to match. Biggest mistake I see with union is that most people leave off the 'ALL' - not realizing that SQL will remove duplicate lines otherwise.

If you're using the results from these two queries in ADO, use NextRecordset to loop through one then the second result set.

Deuce - if you're using union you'll only get one recordset. In some cases returning multiple recordsets will make more sense...union won't work, you need it separated anyway, etc. Multiple recordsets are a great way to reduce round trips.
