Hello,
I need a insert statement to do a calculation of adding cells from two different tables, TBSIGNAL1 and TBSIGNAL2. The result will be inserted into the TBSIGNAL3 as below
SID1C1 of TBSIGNAL3 = SID1C1 of TBSIGNAL1 + SID1C1 of TBSIGNAL2
SID1C2 of TBSIGNAL3 = SID1C1 of TBSIGNAL3 + SID1C2 of TBSIGNAL1 + SID1C2 of TBSIGNAL2
SID1C3 of TBSIGNAL3 = SID1C2 of TBSIGNAL3 + SID1C3 of TBSIGNAL1 + SID1C3 of TBSIGNAL2
SID1C4 of TBSIGNAL3 = SID1C3 of TBSIGNAL3 + SID1C4 of TBSIGNAL1 + SID1C4 of TBSIGNAL2
And so on...
Please see table data and structure below.
All help is much appreciated.
 TBSIGNAL3 should have the result below.
SID TID C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12
1 3 4 8 12 16 20 24 28 32 36 40 44 48

Looks like a pretty simple insert/select is all that's needed. The additions for the later columns are going to be pretty long, but not actually complicated as such  you just add more columns to the addition.
Just give it a try.

it works only when I tried to insert the first r1 row. As long as I tried to add the second r2 row or more to the statement, I got the 0 rows inserted message as below.
> INSERT INTO TBSIGNAL3 (SID, TID, C1)
SELECT SID, 3, r1
from
(select a.sid,
(a.c1 + b.c1) as r1
from tbsignal1 a, tbsignal2 b
where a.sid = 1 and b.sid = 1)
/
1 row inserted.
