Except you can't really use that trigger because there are ways to bypass it.
If you make changes and the exit the form (or clear the blocks, or execute a query) then forms will ask you if you want to save changes. If you click yes forms will commit the changes without firing key commit.

Not really, what I'm suggesting is too wide ranging and generic to give code examples.
Bottom line is - if your form design relies on validating or modifying data when the user clicks on save you need to change your form design - not change some code to get around this, but change the business process of how the form is to be used so it's not necessary in the first place.
Of course this assumes you can't actually do what is necessary in when-validate-record or the pre/post-insert/update/delete triggers. If those work they would be the first choice.

Dear do just do this
create table test1(item_no varchar2(6),item_name varchar2(20),qty number(8));
create table stock(item_no varchar2(6),item_name varchar2(20),stock_qty number(8));
insert into TEST1 VALUES('001','XBOX',2);
insert into TEST1 VALUES('002','PLAYSTATION',5);
insert into TEST1 VALUES('003','LED TV',10);
insert into stock VALUES('001','XBOX',10);
insert into stock VALUES('002','PLAYSTATION',50);
insert into stock VALUES('003','LED TV',80);
COMMIT;
after call test1 in the form make one button and write simple
begin
go_block('test1');
first_record;
while :qty is not null loop
update STOCK set STOCK_QTY=(select STOCK_QTY+:QTY from STOCK
where ITEM_NO=:ITEM_NO)where ITEM_NO=:ITEM_NO;
next_record;
end loop;
MESSAGE('TRANSACTION SAVED AND UPDATED ANOTHER TABLE WHICH IS NOT IN DATA BLOCK');
MESSAGE('TRANSACTION SAVED AND UPDATED ANOTHER TABLE WHICH IS NOT IN DATA BLOCK');
commit;
FIRST_RECORD;
end;
OK take this FMB file it will be more easy for you.

DEAR Read the question ABOVE Standard "SAVE" button otherwise you can do this put this code in FORM-LEVEL-TRIGGER-PRE-COMMIT and when you are gonna save records just put below "clear_block(do_commit) and remember removed commit from this code and dear one more think, one by one you can also save records by using key_next-item or whatever trigger suits you but you have to removed loop from this code
clear_block(do_commit);
Regard
Mughal

What makes you think I haven't read the question?
The answer was key-commit.
I pointed out why key-commit should never be used.
And you can't put the code in your post above in pre-commit, it doesn't allow unrestricted built-ins.

mughals_king wrote on Mon, 04 November 2013 14:57DEAR read my i said one by one records when you wanna saved
You put that in your update at the same time I was posting my reply, so I wasn't in a position to see it.

PRE-COMMIT-----tRIGGER
update STOCK set STOCK_QTY=(select STOCK_QTY+:QTY from STOCK where ITEM_NO=:ITEM_NO)where ITEM_NO=:ITEM_NO;
That's not going to work - pre-commit fires once when you commit, not once per record.
mughals_king wrote on Mon, 04 November 2013 14:57
Key-next-item---whatever suits you
I sincerely hope that key-next-item doesn't suit anyone for this purpose. Having a form that tries to update another table every time a user tabs through a particular field strikes me as a really bad idea. Plus of course if they don't tab through but use the mouse to navigate instead, the update will never happen. Key-next-item should never be used for data modification or validation. People who rely on it end up with corrupted data.
The obvious place for such an update statement is pre-insert and pre-update.

clear_block(do_commit);
No idea why you're mentioning this.

No dear i am not intentionally adding these things don't take personal, as far as concern KEY-NEXT-ITEM trigger i saw in your country central london when i went there your programmers designed for barcode reader device they were using KEY-NEXT-ITEM--->Trigger where barcode item was pointed the cursor that time automatic records was saving the record one by one. you can't say KEY-NEXT-ITEM--->triggger useless
and i am also using this trigger for barcode reader as well and its successfully working in largest reputed companies.

And why is debating how forms works mutually exclusive to helping people?
mughals_king wrote on Mon, 04 November 2013 16:05
i am sorry again if you feel bad
I don't feel bad at all, I'm just pointing out why I think your suggestions won't work. This is part of how forums work - people make suggestions, if there are problems with them other people point those problems out.
mughals_king wrote on Mon, 04 November 2013 16:05
i personally request to you pls read this question
I've already pointed out that I've read the question, if you think I've overlooked something you need to point out what that is. I certainly see no evidence the OP is using a bar-code reader. Obviously it would help if they stated why they are trying to do what they've asked for.
As for pre-commit. I don't have a working forms instalation handy to test it but the documentation is very clear - pre-commit fires once when you commit.
So have you tested it for a multi-record block with multiple records being modified before clicking on save? Because I'll be amazed if it works properly in those circumstances.
The documentation also states this:
Quote:
Note: If you perform DML in a Pre-Commit trigger and the trigger fails, you must perform a manual
rollback, because Forms Developer does not perform an automatic rollback. To prepare for a
possible manual rollback, save the savepoint name in an On-Savepoint trigger, using
GET_APPLICATION_PROPERTY (Savepoint_Name). Then you can roll back using
ISSUE_ROLLBACK (Savepoint_Name).
Which would make me really nervous of putting updates in it.
As for key-next-item - it might be ok for a form connected to a bar-code scanner with no mouse connected, but for a standard web-form it should only be used for navigation code, which is why it exists, if you use it to update data then sooner or later the data won't get updated when it should.

standard web-form
Dear i never mention in my previous posts that pre-commit will work for multi-record block. nor i discussed about web-form
if you are pointing my code which i have posted above for updation it is properly and 100% working on button pressed you can check whenever you want that's why i uploaded my fmb file with tables anyway take care.

a) You originally suggested putting code that looped over the block in pre-commit.
b) If you've got a solution that only works for a subset of forms you need to make that clear.

So? They do not behave any differently in this regard from client-server.

I imagine it does work in when-button-pressed and if the users remember to click on the button then great, if they don't though you have a problem.

What on earth was the point of that statement?
You've made some suggestions. I've pointed out technical reasons why I think they're not generally a good idea based on verifiable facts of how forms works.
That's not an argument from authority, that's an argument from fact.
If you think I've missed some relevant facts, by all means point them out.
I know you know a fair bit about forms from your posts here, but that does not change how pre-commit and key-next-item work.
