SYS_REFCURSOR as OUT parameter - oracle

Question

I have a table contains (username-primarykey,password,age,gender);
have to create procedure like procedure(username in varchar,s_cursor out sys_refcursor);
procedure has to accept username and returns row (where username=in parameter )as cursor.
Rule:Cursor must and should be having unique sequence no along with the record it gives.
example:(unique no(sequence),username ,password,age,gender)
Every time procedure should return single record along with uniqueno(sequence)

Answer 1

You can try something like this, if you need more information you have to provide more details.
Create a sequence for unique no.
CREATE SEQUENCE emp_seq
MINVALUE 1
MAXVALUE 999999999999999999999999999
START WITH 1
INCREMENT BY 1
CACHE 20;
Create a procedure which returns sys_refcursor as OUT parameter and emp_id as IN parameter
CREATE OR REPLACE PROCEDURE get_employee_details (user_id
YOURTABLE.USERNAME%TYPE,
emp_cursor OUT SYS_REFCURSOR)
AS
BEGIN
OPEN emp_cursor FOR
SELECT emp_seq.NEXTVAL,
USERNAME,
PASSWORD,
AGE,
GENDER
FROM YOURTABLE
WHERE USERNAME = user_id;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
DBMS_OUTPUT.put_line ('<your message>' || SQLERRM);
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line ('<your message>' || SQLERRM);
END get_employee_details;
/
And to execute the procedure from sqlplus
variable usercur refcursor;
DECLARE
user_id YOURTABLE.USERNAME%TYPE;
BEGIN
user_id := 'JON';
get_employees(user_id,:usercur);
END;
/
print usercur
Update 1
I assume that you are calling your procedure from sqlplus or from Toad, then you could execute your procedure as
variable dcursor refcursor;
DECLARE
p_arrival DEFAULT_DETAILS.ARRIVALCOUNTRY%TYPE;
BEGIN
p_arrival := '123';
PROCEDURE_SAMPLE(p_arrival,:dcursor);
END;
/
print dcursor
Update 2
To execute procedure from SQL Developer, do as
var usercur refcursor
exec procedure_sample('AU',:usercur)
print usercur
