I have 2 parameter queries that I need to combine onto 1 report. It was
suggested that I try a Union query but I have no idea even where to start.
Any advice?
A UNION query may work if the two queries both have the same number of
fields of matching datatypes. Press F1 for Access Help and search for
UNION for a pretty-good description of how to create one.
If the two queries have different "shapes", or if you want the user to
see the two queries as separate lists on the same report page, you may
do better to use one unbound Report with two Subreports, one based on
each query.
