help in query

can i get values in result set as weeknum alone from 1 to 53 using all_objects.

i wrote a query but it is returning only one week number. i will paste it over here.

but i want it to be done without using level and connect by....



select to_char(trunc(sysdate,'yyyy')+(rownum-1),'ww-yyyy') weeks
from all_objects
where rownum <=366
and to_char(trunc(sysdate,'yyyy')+rownum-1 ,'dd') = 1




Please rectify the mistake in the query... ASAP

Re: help in query

hi Sailaja,

can you try the following:

yogeeraj@mydb.mu> r
1 select distinct to_char( dt+1, 'iw' )
2 from ( select trunc(sysdate,'YY')+rownum dt
3 from all_objects
4 where rownum < 366 )
5* order by 1

Re: help in query

hi,

Once 'dirty' way to achieve this is:

yogeeraj@mydb.mu> r
1 select to_char( dt+1, 'iw' )
2 from ( select trunc(sysdate,'YY')+rownum*7 dt
3 from all_objects
4 where rownum < 53 )
5* order by 1
