Nested cursor issue

[Francesco Lamonica]

Hi all,
I've got a stored procedure (sp1) and a stored function (sf1)

in my sp1 i have:
begin
declare done boolean default false;
declare cur_tel cursor for select field1,f2,f3 from table1 limit 10;
declare continue handler for not found set done=true;

open cur_tel;
myloop: loop

fetch cur_tel into v1, v2, v3;
if done then
leave myloop;
end if;

select sf1(v1,v2,v3,2) into v4;

-- just for debugging purposes
insert into tempt (test1,test2,test3,test4) values (v1, v2, v3, v4);

end loop;
close cur_tel;
end

and in sf1 i have:

begin
-- vars
declare ccost double default 0;
declare done2 boolean default false;
-- cursor
declare cur_timerate cursor for select anotherfield,af2 from t1;
declare continue handler for not found set done2=true;

open cur_timerate;
cloop: loop

fetch cur_timerate into vv1,vv2;

if done2 then
leave cloop;
end if;
return 23;
end loop;
close cur_timerate;

return ccost;
end;

what happens is that i always get 0 as a result of the sf1. the "return 23" statement is never hit! not even if i change the cursor declaration to something like:

declare cur_timerate cursor for select 10,20;

it just seems to hit the not found event each and every time.

Any idea of what i might be doing wrong?

(i am using 5.0.70 on a gentoo amd64 box)

thanks in advance
