Hello,
Lets say I have two tables like
A:
1,11
2,15
and
B:
1,10
4,11
5,10
and joinin them
J = JOIN A by $0 FULL, B by $0
I get J:
1,11,1,21
2,16,,
,,4,11
,,5,10
which is a full outer join:
what I need is:
1,31
2,16
4,11
5,10
so I want to join by key, and then sum some fields.
the regular sum operator is for group or agregate summing and can
not do it.
any ideas / recomendation / help greatly appreciated.
best.
