Sum a Union

Hi,

I can return results of a union easily enough, but I wish to sum the records
first. Is this possible in a single SQL statement? Or do I have to use
separate ones to sum up after the union?

Cheers,
Chris

Hi

You can try something like:

SELECT Sum(Col1)
FROM ( SELECT Col1 FROM TableA
UNION ALL Select Col1 From TableB ) A
