table1 has a group with a count of dates summary & table 2 on same report
has a group with a count of a field (happens to be a date field as well)
id like to add a field which is the sum of both & grouped by date

select
dt,
sum(myValue)
from
(
select
dt,
count(x) as myValue
from
table1
UNION ALL
select
dt,
count(y)
from
table2
) as combinedTable
group by
dt
This takes the output from each and concatenates them together (basically, a
0-cost operation), then summarizes accross them.
