Actually it works partially. If I want to get the next 6 rows from a particular date, how would i do it. say i have all these dates 7/11/2005 7/12/2005 7/13/2005 7/16/2005 7/18/2005 7/21/2005 7/24/2005 7/25/2005 7/26/2005 7/27/2005 7/28/2005 7/29/2005 I want all the dates from 7/21/2005 to 6 days later

Check this out if it works for input 7/21/2005 select date_n, rownum from (select distinct (to_date(tab.reqDate)) as date_n from tbl tab where to_date(tab.reqDate) > to_date('07/21/2005','DD/MM/YYYY') order by to_date(tab.reqDate) desc) where rownum <= 6 Check this out and let me know if this query works.

Sorry It will be like this Check this out if it works for input 7/21/2005 select date_n, rownum from (select distinct (to_date(tab.reqDate)) as date_n from tbl tab where to_date(tab.reqDate) <= to_date('21/07/2005','DD/MM/YYYY') order by to_date(tab.reqDate) desc) where rownum <= 6 Please check the way i have given the input, it is not '7/21/2005' but '21/07/2005' as we want 'DD/MM/YYYY' format Check this out and let me know if this query works. Regards Makarand Parab

Sorry i messed up a bit again, i gave you the query for previous dates Here is the final one i hope select date_n, rownum from (select distinct (to_date(tab.reqDate)) as date_n from tbl tab where to_date(tab.reqDate) >= to_date('21/07/2005','DD/MM/YYYY') order by to_date(tab.reqDate) desc) where rownum <= 6 Regards Makarand Parab

Hi Meera My core expertise is Java, J2EE and i am learning SQL. So if u have any problem with SQL let me know. I would surely give a try as it would be a live project for me . Good to know that it worked fine. Enjoy Regards Makarand Parab
