List of all SUNDAYS by query

Question

hi friends,
is there any way to get the list of all SUNDAY's dates in the current year through a SQL query.
Thanks before hand.

Answer 1

The following procedure might help:
procedure qry_date(rec_set in out sun_dt) is
declare
dt date;
cur_yr varchar2(4);
begin
select to_char(sysdate,'YYYY')
into cur_yr from dual;
dt := to_date(cur_yr,'YYYY');
/* dt now contains 01/01/YYYY */
/* detect the first sunday of the year
and insert the date into database */
loop
if to_char(dt,'DY')='SUN' then
insert into all_sunday_dates (dt);
exit;
end if;
dt := dt+1;
end loop;
/* extract all sundays for the current year and insert into database */
loop
dt := dt+7;
if to_char(dt,'YYYY') <> cur_yr then
exit;
end if;
insert into all_sunday_dates (dt);
end loop;
commit;
open rec_set for
select dt from all_sunday_dates;
end;
The in/out parameter type 'sun_dt' is a ref cursor and all this stuff needs to be defined in a package;
