Can we have ORDER by along with SQLX functions?

Question

Hi All,
I have used the following SQL query to generate a XML file.
select XMLElement("rowset", XMLForest('yyyymmdd hh:mm',"file_date", 'yyyymmdd' "business_date"),XMLElement("privilege", XMLForest(user_name "User_Name",user_role "User_Role"))).extract('/*')
from (
select * from
((select user_name, user_role from a
union
select user_name, user_role from b) tab_a,
(SELECT TO_CHAR (current_timestamp, 'YYYYMMDD HH:MI') file_date,
(SELECT TO_CHAR (business_date, 'YYYYMMDD')
FROM c) business_date
FROM DUAL) tab_b)
group by business_date, file_date;
Can someone suggest how to modify this query in order to sort the rows on user_name and then user_role?
Thanks in advance.
Annie

Why not just use an ORDER BY clause? Also, it's always very helpful to post any SQL code in \ tags so it's readable.SELECT XMLElement("rowset", XMLForest('yyyymmdd hh:mm',"file_date", 'yyyymmdd' "business_date"),XMLElement("privilege", XMLForest(user_name "User_Name",user_role "User_Role"))).extract('/*')
FROM
SELECT *
FROM
SELECT USER_NAME, USER_ROLE FROM A
UNION
SELECT USER_NAME, USER_ROLE FROM B
) TAB_A
SELECT TO_CHAR (CURRENT_TIMESTAMP, 'YYYYMMDD HH:MI') FILE_DATE
SELECT TO_CHAR (BUSINESS_DATE, 'YYYYMMDD')
FROM C
) BUSINESS_DATE
FROM DUAL
) TAB_B
GROUP BY BUSINESS_DATE, FILE_DATE
ORDER BY USER_NAME /* ORDER BY CLAUSE HERE */
, USER_ROLE;
