I have these sub-queries in Oracle (11g):

(select ID, F1 FROM ..) p
(select ID, F2 FROM ..) q
(select ID, F3 FROM ..) r
(select ID, F4 FROM ..) s

From which I need the O/P like:
ID   F1    F2   F3   F4
-----------------------
1    6      17     null null
2    null   3       8    null
3    null  4        7    2
4    3     6       11   23
5    8     null     null 22

ID is unique in the O/P.The above comes from these input values:
p:
Id  F1
-------
1   6
4   3
5   8

q:
Id  F2
-------
1  17
2  3
3  4
4  6

r:
Id  F3
-------
2   8
3   7
4   11

s:
Id  F4
-------
3   2
4   23
5  22

Why could you not use the select from the other question?

Just use a simple union:
SELECT ID, MIN(F1) AS F1, MIN(F2) AS F2, MIN(F3) AS F3
FROM
(
select id,f1, null f2, null f3, null f4 from p
union all
select id,null, f2, null f3, null f4 from q
union all
select id,null, null f2, f3, null f4 from r
union all
select id, null, null f2, null f3, f4 from s
)
GROUP BY ID
order by id

It worked perfectly. Thank you. I changed the line
MIN(F1) AS F1, MIN(F2) AS F2, MIN(F3) AS F3
changed from MIN to MAX.
