Report Query..help

Question

Hi,
I have supplier, qutation and invoice table.
Supplier:
supp_id = supp_name
1 = ABC
2 = XYZ
Qutation:
quta_id = quta_date = supp_id
1 = 12-Dec-2008 = 1
3 = 15-Dec-2008 = 1
5 = 18-Dec-2008 = 1
Invoice:
inv_id = inv_date = supp_id
150 = 01-Dec-2008 = 1
250 = 11-Dec-2008 = 1
100 = 15-Nov-2008 = 2
Qutation and Invoice are non dependent.
I have a report which needs to display following information:
Supplier with total qutation and invoices
Supplier Name = Qutation ID = Qutation Date = Invoice Id = Invoice Date
ABC = 1 = 12-Dec-2008 = 150 = 01-Dec-2008
ABC = 3 = 15-Dec-2008 = 250 = 11-Dec-2008
ABC = 5 = 18-Dec-2008 = * = *
XYZ = * = * = 100 = 15-Nov-2008
You can see there is no record for Invoice in 3rd row and qutation data for 4th row thats why it is showing '*'.
Could you please tell me how to manage such output using Single query
Thanks in advance,
RSD

Check this out. You need FULL JOIN
SQL> with supplier
  2  as
  3  (
  4     select 1 supp_id, 'ABC' supp_name from dual
  5     union all
  6     select 2, 'XYZ' from dual
  7  )
  8  , Qutation
  9  as
10  (
11     select 1 quta_id,  to_date('12-Dec-2008','dd-mon-yyyy') quta_date, 1 supp_id from dual
12     union all
13     select 3, to_date('15-Dec-2008','dd-mon-yyyy'), 1 from dual
14     union all
15     select 5, to_date('18-Dec-2008','dd-mon-yyyy'), 1 from dual
16  )
17  , Invoice
18  as
19  (
20     select 150 inv_id, to_date('01-Dec-2008','dd-mon-yyyy') inv_date, 1 supp_id from dual
21     union all
22     select 250, to_date('11-Dec-2008','dd-mon-yyyy'), 1 from dual
23     union all
24     select 100, to_date('15-Nov-2008','dd-mon-yyyy'), 2 from dual
25  )
26  --

28  --
29  select supp_name, t.*
30    from (select decode(q.supp_id, null, i.supp_id, q.supp_id) supp_id, q.quta_id, q.quta_date, i.inv_id, i.inv_date
31       from (select row_number() over(partition by supp_id order by quta_id) rno, q.*
32               from qutation q) q
33       full join
34            (select row_number() over(partition by supp_id order by inv_id) rno, i.*
35               from invoice i) i
36         on q.supp_id = i.supp_id
37        and q.rno = i.rno) t
38    join supplier s

40  /
