This is what I am think I am looking to do in package....but then how do I
return the resultsets? Does this look right?
Can I open p_cursor1 for cursor1 and
PROCEDURE BA_TRD_PROC(
P_CURSOR1 out cursorvar,
P_CURSOR2 out cursorvar,
P_START_DATE EV.TRDDATE%type,
P_END_DATE EV.TRDDATE%type
)
is
begin
cursor1 is
select ID, other_stuff
from x;
cursor2 (p_ID in cursor1.ID%TYPE) is
select whatever
from y
where ID = p_ID;
open p_cursor1 for cursor1;
open p_cursors2 for
for outer_rec in cursor1 loop
for inner_rec in cursor2(ID) loop
...
end loop;
end loop;
Thanks
Kathy

Kathy,
OK. So they will get the first cursor back and process each record and call
a second cursor - like a double loop?
Or you could return both cursors at the same time and do what I suggested -
the second cursor is returning the data as a result of the first cursor.
I'm still having trouble understanding how you want this to work.

no, they want two distinct cursors.... We had two procedures using dates for
the parent and the child queries but
the dates can be relied upon. (bad third party package, bad data, bad
vendor...)
So as not to break the original UI or have to change code (god forbid
developers change their code here) I have to come up with another solution.
Otherwise I agree with you.

Kathy,
Why even return the first cursor? Why not return the second cursor with the
results of the first cursor already wrapped in the second?
Does this make sense? What they *really* want is the results from the
second cursor. So why not just give it to them with enough items in the
select list so they can get the data they want?

what I need to do is return a cursor from one query in a procedure.... no
problemo
What I need to do is :
for every ID returned in the first query returned ....use this in the where
condition of the child query.
Yes they want two separate cursors returned. so a function is out.
The first query is intensive so I don't want to execute it twice.
This will be executed quite a bit and returns a fair amount of data.
Thanks,
Kathy
