Subject How do you get a summary SUM() from a union of tables
Author cornievs
Hi

I have 2 (and more) tables with identical structure:

Simplified structure and data:
CODE VARCHAR(15)
QUAN INTEGER

Table A
Item1, 50
Item1, 40
Item2, 70

Table B
Item1, 50
Item2, 100
Item2, 30

I need to get the sum(QUAN) for all the rows in all the tables group by CODE

Item1, 140
Item2, 200

Is there a way I can do it with a UNION? Or is there a better way?

Regards
