Oracle Forms 10G database 10G Windows XP
I have Two Data Blocks Master and Detail
in Detail data is fetched through a cursor not from master table but from another table eg
if user selects the product code in master then the tests which are defined against that product fetched in detail.
But the problem is when user selects the product code and press button the form message displayed do u want to save the changes and then it fetch records one by one on the same row
Firstly i want to display that data on multiple lines depends on records and secondly to disable that message but not hiding message
by setting message level
the Cursor code is as below please check
declare
v_flag boolean :=False;
cursor cr_product is
select t.test_code, t.method_code, t.min_range, t.max_range
from qcl13_test_method t
where t.prod_code = :detail.prod_code
and t.active = 'Yes';
rec_pr cr_product%rowtype;
begin
--clear_block;
open cr_product;
loop
fetch cr_product into rec_pr;
exit when cr_product%notfound;

:detail.test_code:=rec_pr.test_code;
:detail.method_code:=rec_pr.method_code;
:detail.min:=rec_pr.min_range;
:detail.max:=rec_pr.max_range;

next_record;
v_flag:=True;
end loop;
-- v_flag:=True;

close cr_product;
if v_flag=False
then
message('No data Found');
message('No data Found');
--else
-- null;

end if;

end;

1- if this message appears, that means that you are using a database data block and the changes need to bee comitted.
2- the product code must not be in the detail if you are using it as parameter ( = :detail.product_code)
3- you need to create the record by using the crate_record builtin
4- the v_flag must not be inside the loop, you put it to true if the cursor returns at least one row (after the first fetch):
if cursor%found then v_flag := true;

Don't use cursor:
Populate block using cursor
http://www.orafaq.com/forum/m/605/67467/?srch=populate+block+cursor+create_record#msg_605
and my feelings about it.

Another one of my rants.

Use Master-Detail:
