Hi,
I have got 2 Tables like the one displayed below
Table - Test1
 no            name   
 shi/chi/oo1   sss
 chi/sin/002   bbb
 ind/usa/003   ccc


  Table -- Test2
  no            ed_no    age    sal
  shi/chi/oo1  shichi001 20     2000
  chi/sin/002  chisin002 20     4000


I have to get data from both the tables in a single row so i am
using join condition.I should always get data from Table Test1
even if data is not there in Table Test2.So i am using Outer join
and the ed_No can be with '/' and without '/' both should be matched

so i gave query like this

  select a.no,a.name,b.age,b.sal
  from(
      select no,name
        from test1
       where no='chi/sin/002') a,
     select age,sal
       from test2 
      where no='chi/sin/002 '
         or ed_no='chisin002') b
where (a.no =b.no(+) or b.ed_no = replace(a.no,'/',''))
  and a.no='chi/sin/002';



This query is giving me error.
can any one tell me how to do it
Thanks in advance

Please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter) and align the columns in result.
Use the "Preview Message" button to verify.

Working back from your query, I think what you're trying to do is outer join A to B on one of two different columns.

This won't work, and would give you an ORA-1719. I've no real idea if this is the problem, as you didn't bother to tell us the error you got.

Assuming I'm right, try this (I've played with the test data a bit to show up the effective conditional outer join):
drop table test_0039;
drop table test_0040;

create table test_0039  (no varchar2(30),           name varchar2(30));

insert into test_0039 values ('shi/chi/001',   'sss');
insert into test_0039 values ('chi/sin/002',   'bbb');
insert into test_0039 values ('ind/usa/003',   'ccc');

create table test_0040 (  no varchar2(30),            ed_no varchar2(30),   age number,    sal number);

insert into test_0040 values ('shi/chi/oo1',  'shichi001', 20,     2000);
insert into test_0040 values ('chi/sin/002' , 'chisinoo2', 20,     4000);

select a.no
      ,a.name
      ,nvl(b.no,c.no) 
      ,nvl(b.ed_no,c.ed_no)
from   test_0039 a
      ,test_0040 b
      ,test_0040 c
where a.no = b.no(+)
and   replace(a.no,'/','') = c.ed_no(+);

NO                             NAME                           NVL(B.NO,C.NO)                 NVL(B.ED_NO,C.ED_NO)
------------------------------ ------------------------------ ------------------------------ ------------------------------
shi/chi/001                    sss                            shi/chi/oo1                    shichi001
chi/sin/002                    bbb                            chi/sin/002                    chisinoo2
ind/usa/003                    ccc                            null                           null
