but when i tried to put in the main query am getting ORA-00933 not sure how to fix this. Can some one advice me where am making wrong.
Work Around query :
   SELECT ALTID.B_SYS_ID FROM N08.B_ALT_ID_TB ALTID WHERE ALTID.B_ALT_ID
           IN ( SELECT MEDCO.RE_MEDCD_ID_NUM 
             FROM N09.T_MEDCD_ID MEDCO
          INNER JOIN N09.T_POLY POLY
                ON POLY.RE_UNIQUE_ID = MEDCO.RE_UNIQUE_ID) AS B_SYS_ID
Need to integerate the above column in the below query.
Main Query :
SELECT 'Diff' AS SC,
     POLY.ID,
      ALTID.B_SYS_ID FROM N08.B_ALT_ID_TB ALTID WHERE ALTID.B_ALT_ID
           IN ( SELECT MEDCO.RE_MEDCD_ID_NUM 
             FROM N09.T_MEDCD_ID MEDCO
          INNER JOIN N09.T_POLY POLY
                ON POLY.RE_UNIQUE_ID = MEDCO.RE_UNIQUE_ID) AS B_SYS_ID,
    NULL AS BEG_DT,
  NULL AS ID,
FROM
   N09.T_POLY POLY

Hi Frank,
Thanks for your responces. The Error am getting is at line number 7 & col# 55 -- ON POLY.RE_UNIQUE_ID = MEDCO.RE_UNIQUE_ID) AS B_SYS_ID,.
I also changed the alias name in thesubquery as S-poly and left the main query alias as POLY. You still haven't posted a completed query, or any sample data and results.
But still i am getting the same error message.
Error Message
ORA-00933 : Sql command not properly ended
oo933 00000 - "Sql command not properly ended"
Vendor Code 933 Error at line 7 column 55
Iam framing a select query, The work around query is used to checkhow to reterive the value from the DB and with the business rules. on which the framing
select query the B_sys_id comes in column 3 and i still have more columns to select. Hence i even tried as below
SELECT 'Diff' AS SC,
POLY.ID,
ALTID.B_SYS_ID FROM N08.B_ALT_ID_TB ALTID WHERE ALTID.B_ALT_ID
IN ( SELECT MEDCO.RE_MEDCD_ID_NUM 
             FROM N09.T_MEDCD_ID MEDCO
             WHERE POLY.RE_UNIQUE_ID = MEDCO.RE_UNIQUE_ID),
NULL AS BEG_DT,
NULL AS ID,
FROM
N09.T_POLY POLY
But still the same error message i got.
Hence i just tried as below
SELECT 'Diff' AS SC,
1 as dummy,
2 as dummy_1,
ALTID.B_SYS_ID FROM N08.B_ALT_ID_TB ALTID WHERE ALTID.B_ALT_ID
IN ( SELECT MEDCO.RE_MEDCD_ID_NUM 
             FROM N09.T_MEDCD_ID MEDCO
          INNER JOIN N09.T_POLY POLY
ON POLY.RE_UNIQUE_ID = MEDCO.RE_UNIQUE_ID)
This is working.
Can you please let me know what is that i need to do if i want to add more columns in the select clause after
this line ON POLY.REUNIQUE_ID = MEDCO.RE_UNIQUE_ID)_
Thanks.
A query (not counting sub-queries) has, at most, only one of each type of clause: one SELECT clause, followed by one FROM clause, followed (optionally) by one WHERE clause. All items to be returned go together in the one SELECT clause. All tables needed are named in the on FROM clause. All filtering conditions go together in the one WHERE clause.
Perhaps you meant something like this:
SELECT  'Diff'           AS SC
,          POLY.ID
,           ALTID.B_SYS_ID
,       NULL AS BEG_DT
,     NULL AS ID
FROM     N08.B_ALT_ID_TB ALTID
JOIN    N09.T_POLY     POLY   ON  altid.column_a  = poly.column_b
WHERE      ALTID.B_ALT_ID     IN (
                      SELECT  MEDCO.RE_MEDCD_ID_NUM 
                         FROM    N09.T_MEDCD_ID           MEDCO
                         WHERE   POLY.RE_UNIQUE_ID      = MEDCO.RE_UNIQUE_ID
                  )With the little information I have, I can't even guess what the real join condition(s) might be. I used
ON  altid.column_a  = poly.column_bjust to show the correct syntax.
