Hi everyone.
The message::
" Do You Want To Save The Changes You Have Made ?"When i press the button which query the records then this message comes with record and there are many more conditions where i faced this message.
And when i press NO option then it remove the message otherwise if i press the YES option it saves the record.
Third oion is NO.

So for gertting rid of this should i have to disable the insert property while query.
pls send me some tip to override this message.

Shaila.

Check the block status , if it is "CHANGED" just commit the form using COMMIT or POST.

First of all, you should know why you get this message. Does this message also occur without you having changed anything manually?

It means your record status has been changed, i.e. some field in the form has been changed either with or without your knowledge.

I'd say, check your post-query trigger. It is very often that the problem lies in there. Are there any database fields being updated there. If so, and they shouldn't be saved, set the record status property to QUERY_STATUS.

I am attaching this .fmb(Scott's schema).
This is just an example here when i press the button it donot make any query. It wants a value to be entered first for query.

And when i give the value and press button then it again show that message about which we discussed earlier.

So how do i query the record by pressing the button.

Help me out here. I don't have forms available to me but working through an intelligent flat file editor I believe that you have the following code in your form.

POST-QUERY (EMP)

BEGIN
  :dates := SYSDATE;
END;

WHEN-BUTTON-PRESSED (EMP.PUSH_BUTTON5)

BEGIN
  Go_block('emp');
  
  execute_query;
  
  IF :system.form_status = 'changed' THEN
    COMMIT;
  END IF;
END;

What is happening is that EVERY record that is retrieved is having its 'dates' field updated, the status will be set to 'CHANGED', and you are asking the form to 'commit'.

Now before we start correcting your code there are three things you SHOULD be doing.
1) ':dates' should be ':emp.dates' - ALWAYS specify block and item.
2) When testing Oracle defined values ALWAYS do them in upper case. So 'changed' should be 'CHANGED'.
3) In a Form use Commit_Form. It you want a commit done AND DONE NOW IRRESPECTIVE of the status of a form then use 'Standard.Commit'.

If you want Emp.Dates initialised to 'sysdate' then define the default value of Emp.Dates to '$$DATE$$' or '$$DATETIME$$'. If you want Emp.Dates to be updated when the record is changed then do it in a database trigger.

Okay, now remove the Post-Query trigger, remove the form_status code IF statement from the push_button, do a Ctrl-Shft-K (compile all), then a Ctrl-T (generate) and try you program again.

Tell us what extra behaviour you want from your form and we will help you with it.

Thanks for giving reply..
Now this time when i ran my form no item is updated and still i am getting same message.

It first needs a value for query and when the button pressed it retrieves records.

But i want that only by pressing a button it retrieves records.

Can you tell me more about the 'Standard.Commit'.

Okay. Now you have:

WHEN-BUTTON-PRESSED (EMP.CLEAR)

CLEAR_FORM;

and WHEN-BUTTON-PRESSED (EMP.PUSH_BUTTON5)

EXECUTE_QUERY;

Do you have any 'initial values' set?

--Kiran.

FUNCTION GET_BLOCK_PROPERTY
(block_id Block,
property NUMBER);
FUNCTION GET_BLOCK_PROPERTY
(block_name VARCHAR2,
property NUMBER);

Do these functions above retrieve block status???

Thanks!

You can get the current block status using System.Block_Status and the status of any block ('blk') using Get_Block_Property('blk',STATUS).

POST is similar to COMMIT (database triggers fire, constraints are tested) but a ROLLBACK will undo ALL changes since the last SAVEPOINT was issued, not just the last command that you issued.

If you want to be able to select which record to delete and undelete then consider adding an 'operation' column/item to the record. Then, on a 'delete', mark it with a 'D'. Then when you 'SAVE' your changes, you run a 'delete' statement which will physically delete all records marked with a 'D'. To undo the 'delete' (before the 'SAVE' is run) you would just remove the 'D' from the 'operation' column.

David

PS Please use 'want to' instead of 'wanna'.

i have form with a master-detail relationship.

tables involved are:
--------------------------
department --being the master
employee --being the detail table

i have attached the form for viewing.

i attached an l-o-v to fill the department fields.
what i wanted was that each tim that i change the department via the l-o-v a listing of all employees under that department is to be shown.
but each time i select a new department using the l-o-v the message(Do You Want To Save The Changes You Have Made ) comes up.how can i suppress this message?

Dear Marvy,
The problem is because your LOV assigns values to DEPARTMENT_ID and DEPARTMENT_NAME fields.
as the values are assigned to the fields, block status will be modified as 'CHANGED' .
Since it is a datablock, it will ask you wether to save this new values.

Now what you have to do is simple.

1. Create a parameter DEPTID to save the department_id (primary key).
2. In the LOV ,change the return value of deparment_id to this parameter.
3. In the KEY-LISTVAL trigger, modify the code like this

  LIST_VALUES;
  clear_form(no_validate);
  EXECUTE_QUERY;

4. Now in PRE-QUERY Trigger of DEPARTMENT ,write this code.

  if :parameter.DEPTID is not null then
	:DEPARTMENT.DEPARTMENT_ID:=:parameter.DEPTID;
        :parameter.DEPTID:=null;
  end if;

Now run the form.
I think you understood the coding. If need clarifications, Please reply.

Regards
Sasi..

thanks djmartin and sasipalarivattom for your qick responces.

to answer djmartin's question: no i did not want to make any change to the record. i only wanted the values selected from the l.o.v to be displayed in the DEPARTMENT_ID and the DEPARTMENT_NAME fields of my form but according to sasipalarivattom the block status will be modified as 'CHANGED'.
i now understand. thanks guys!!

sasipalarivattom , i made the modifications that you told me to do.when i press the button the l.o.v did not launch.the employee datablock was filled with all the emploees.
-----------------------------------------------

I then commented the code in the key-listval trigger of DEPARTMENT.DEPARTMENT_ID :

LIST_VALUES;
--clear_form(no_validate);
EXECUTE_QUERY;

I then compiled and ran program again.it gave the following results:
* the first time the button is pressed after i run the program, the l.o.v does not show up.but the first record in the department table show up in the DEPARTMENT datablock and the employees related to that department shows up in the EMPLOYEE datablock
*if the button is pressed again(for the second time and all other attemps after that) the l.o.v shows up and everthing seems to work perfectly

i just dont know why the l.o.v doesnt show up when the button is pressed the first time

Dear Marvy,

What would I like to say is
Check it yourself. Once if you can understand what is wrong in your
form, you will never forgot it.
One more thing, Do post your thoughts for the use of other members.

One suggestion.
What I heard from my seniors is that use "execute_trigger" command
only when there isn't any other way..

Thanks and Regards
Sasi..

The code you entered was exactly that: you modified item's value. Forms warns you that you'll lose those changes and asks whether you want to save them or not.

And to follow-up from Littlefoot, if you want to query records, you need to enter into query mode before you type into a field, not the other way around.

You need to go into enter-query mode before entering a value for forms to use in the query.
