Random select using multiple tables

Question

Hello World!!!
I'm trying to fix a form I modified last month and it's causing me fits!
I need to add another validation element (email address) to my password validation Form. The problem lies in the fact that I can't simply add an additional SELECT Statement to the query because it won't randomly select the same number that the first one did (records won't match). When I try to JOIN on the tables inside the inner SELECT, basically the same thing happens. I get an a result for the "e-mail" column but it doesn't match the same record as the first two.
Is there an easier way of doing this??? Here's the code I'm using that works for my first two column returns (from the agent_sec_questions Table). I'm trying to add one more column (email) from the agent_data Table.
Thanks in advance for any suggestions.
SELECT security_question, question_number
FROM (SELECT security_question, question_number
FROM agent_sec_questions
WHERE agent_id =
(SELECT agent_id
FROM agent_data
WHERE username = 'john doe')
ORDER BY DBMS_RANDOM.VALUE (1, 9))
WHERE ROWNUM = 1;

Answer 1

Here's the solution I came up with if interested. I got the random number first, then joined my tables. If you have a better one, please let me know...
Chow!

SELECT DBMS_RANDOM.VALUE(1,3) INTO Sel_Num FROM DUAL;
MESSAGE ('Sel_Num= '||Sel_Num||' ID= '||UPPER(:LOGON_BLOCK.USERID));
pause;
               SELECT b.email, a.security_question, a.question_number
               INTO L_email, L_sec_q, L_q_num
          FROM lookup.agent_sec_questions a, lookup.agent_data b
          WHERE b.agent_id = a.agent_id
          AND b.username = TRIM(UPPER(:LOGON_BLOCK.USERID))
          AND a.question_number = sel_Num
               AND ROWNUM = 1;
