Teradata Spool issue in Recursive issue - response (6) by abhishek_abhishek

Hi Raja & Dieter .. Thanks a lot for valuable input.
here my requirement is like :<Input Set table data>
 DAY_ID                   CONTENT_ID                LINE_ID                    Resiliation
1/1/2014                   12345                        07-098787                  1,2
1/1/2014                    12345                       07-098787                  0, ?,1
1/1/2014                     12345                      07-098787                   2,4,5
1/1/2014                      12345                      07-098787                  1,2,3
And the expected output is :
DAY_ID                        CONTENT_ID                            LINE_ID                Resiliation
1/1/2014                      12345                                    07-098787              1,2,0, ?,4,5,3
 
My above query is working fine when record count is very less .. but in case of more than 500 records , its showing spool space issue .
 
I have tried same kind of query with simple rank & concat funtion, but i was not able to remove duplicate in output record set  , below is the output of rank & concat funtion query :
 DAY_ID         CONTENT_ID                      LINE_ID                              Resiliation
1/1/2014       12345                                07-098787                      1,2,0,?,1,2,4,5,1,2,3
While as per requirement no duplicate allowed in the resiliation column.
 
can you please help me to in this scenario ?
Thanks a lot in advance.
