sigh
What we were asking you is to post data we can work with rightaway, so CREATE TABLE statement, and INSERT INTO statement. So: not output, but statements...
Since I'm in a good mood (we're in the semi finals ;) ), here's an example of how you should post your data:
create table a1 as
select 1 quest_code, 'Fibrostenotic' quest_desc from dual union
select 2, 'Inflammatory' from dual union
select 3, 'Int Penetrating/Perforating' from dual union
select 4, 'Perianal Perforating Disease' from dual union
select 5, 'Uc Like' from dual union
select 6, 'Flare Of Disease' from dual union
select 7, 'Immunosuppressive Tx' from dual union
select 8, 'Iv Therapy' from dual union
select 9, 'Stool Consistency' from dual union
select 10, 'Urgency' from dual union
select 11, 'Stool Frequency' from dual union
select 12, 'Bleeding' from dual union
select 13, 'Adb Pain' from dual union
select 14, 'Fever/Chills' from dual union
select 15, 'Fistula' from dual union
select 16, 'Obstructive Sx' from dual union
select 17, 'Extraintestinal Sx' from dual union
select 18, 'Steroid Dependent' from dual union
select 19, 'Sibo' from dual union
select 20, 'Osteoporosis' from dual union
select 21, 'Osteopenia' from dual union
select 22, 'Growth' from dual union
select 23,  'Other' from dual;
create table a2 as
select 1 quest_code, 'U' quest_response, 88 user_id from dual union
select 2, 'U', 88 from dual union
select 3, 'U', 88 from dual union
select 4, 'U', 88 from dual union
select 5, 'U', 88 from dual;
create table a3 as
select 'testuserb' user_name, 88 user_id from dual;Posted like that, we can copy+paste and try to help you rightaway instead of waisting time formatting, putting quotes right etc. etc.
Also use the {noformat}{noformat} tag when you post an example.
That way it will stay formatted and indented.
So, when you type: {noformat}select *
from dual;{noformat}
it will appear as: select *
from dual;when you post it.
Finally, perhaps you could try something like this:SQL> select a1.quest_desc
2 , a2.quest_response
3 , case
4 when (select a3.user_id
5 from a3
6 where a3.user_id = a2.user_id) is not null
7 then (select a3.user_id
8 from a3
9 where a3.user_id = a2.user_id)
10 else (select a3.user_id
11 from a3
12 where a3.user_name = 'testuserb')
13 end user_id
14 from a1
15 , a2
16 where a1.quest_code = a2.quest_code(+);
QUEST_DESC Q USER_ID
