ok this is the package header:
create or replace package get_outvalue_test is
type rec is record (time archive.time%type,
value archive%type);
type value_tab is table of rec index by binary_integer;
procedure get_value(p_returnvalue IN OUT value_tab);
end;
package body :
create or replace package body get_outvalue_test is
procedure get_value(p_returnvalue IN OUT value_tab)
is
ii number;
cursor valselect is
select time,value from archive where u_id=5666
and time=:block.date_item ; -- this is the return date from LOV
begin
open valselect;
ii:=1
loop
fetch valselect into
p_returnvalue(ii).time;
p_returnvalue(ii).value;
exite when valselect %notfound;
ii:=ii+1;
end loop;
end;
end;
this is the error when i compile the package body :
MIssing IN or OUT parameter at index
i hope itis cleare and easy .
