I am trying to retrieve information using a composite variable with the following lines, but it is not working. The error report is further below, and the suppose output is at the bottom. I thank you in advance for any advise.
set serveroutput on
DECLARE
TYPE type_shopper IS RECORD(
shopperid bb_shopper.idshopper%TYPE,
firstname bb_shopper.firstname%TYPE,
lastname bb_shopper.lastname%TYPE,
email bb_shopper.email%TYPE);
rec_shopper type_shopper;
lv_days_num NUMBER(1);
lv_shopper_num NUMBER(3) :=30;
BEGIN
SELECT idshopper, firstname, lastname, email
INTO rec_shopper
FROM bb_shopper
WHERE idshopper = lv_shopper_num
lv_days_num := SYSDATE - rec_shopper.created;
lv_days_num := SYSDATE - rec_shopper.created;
DBMS_OUTPUT.PUT_LINE(rec_shopper.firstname);
DBMS_OUTPUT.PUT_LINE(rec_shopper.lastname);
DBMS_OUTPUT.PUT_LINE(rec_shopper.email);
