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
