Hi,
Check you SQL query, Its returning mutiple rows which you are storing in variables.
If your data returns mutiple row then use cursor to iterate through it.
like
create or replace procedure test is
titl varchar(20);
typ varchar(20);
pric number(10);
nprice number(10);
cursor c is
SELECT title_id, type, price, CASE type WHEN 'history' THEN price + 110
                                                       WHEN 'psychology' THEN price + 120
                                                       WHEN 'computer'   THEN price + 140
                                                       ELSE price END AS "New price"
FROM book
ORDER BY type ASC, title_id ASC;
begin
for r in c loop
dbms_output.put_line(r.titl || r.typ || r.pric || r.nprice);
end;Twinkle
