Hello, I'm trying to sum all the even numbers from 1 to 1000. i.e. 2+4+6+8+10 =30..I accumulate but when the loop goes to the top, the variable is cleared and the last loop value is displayed. The code below is what I'm using. Can I get a variable to hold the accumulated value so that at the end of the loop it display the total sum of all the looped values? Thanks for the help.
DECLARE
TOTAL NUMBER;
TTOTAL NUMBER;
BEGIN
FOR I IN 1..1000 LOOP
IF mod(I,2)=0 then
total:=I + I;
ttotal:=total + I;
END IF;
END LOOP;
DBMS_OUTPUT.PUT_LINE('Total sum of even numbers: '||ttotal);
END;
/

try this
DECLARE
TOTAL NUMBER;
TTOTAL NUMBER;
BEGIN
FOR I IN 1..1000 LOOP
IF mod(I,2)=0 then
--total:=I + I;
ttotal:=ttotal + I;
END IF;
END LOOP;
DBMS_OUTPUT.PUT_LINE('Total sum of even numbers: '||ttotal);
END;
