Adding query results

Question

Hi,
I'm new to SQL, reading and learning a lot, but I have the following question:
There is the following query:
select something test1
, something test2
from dual
I would like to add the query results test1 and test2 into another variable like: test3 = test1+test2
How do I accomplish this?
I'm searching throug the SQL reference guide, but >1600 pages takes lots of time to find the needle in the haystack.
Thanx in advance
Cees

Hello
If you want to do this in SQL you can just do
SELECT
     something test1,
     something_else test2,
     something + something_else test3
FROM
     dual;Or you could do:
SELECT
          test1+test2
FROM
     (SELECT
          something test1,
          something test2
     FROM
          dual
     );If you want to do this in PL/SQL you can do something like:
set serveroutput on
DECLARE
     ln_Result     NUMBER;
BEGIN
     SELECT
          1 + 10
     INTO
          ln_Result
     FROM
          dual;
     dbms_output.put_line('Value of ln_result: '||TO_CHAR(ln_result));
END;HTH
