Respected Sir,

Please see attached file.

In my form one field that takes five digits. for example (00411) and i set its format mask (99-999). When i put less then 5 digits in the field, Oracle Form generate its own Error i.e. FRM-40209 Field must be of Form 99"-"999. I also declare my own alert for this error. but First Oracle Form Display its own Error and then my Alert display.

i want to display my own alert instead of Oracle Form own generated Error. please post the solution.

Dear Shaheer ,

Can you please answer these questions?

1. Are you calling the alert in WHEN-VALIDATE-TRIGGER of the Account No field?
2. Do you have any code in on-error trigger to suppress the default error message ?

Waiting for your reply.

Regards
Sasi..

1) No Sir, i call alert from KEY_NEXT_ITEM trigger. In this trigger i use if condition

if (length(:blockname.fieldname) = 5 )then
go_item('fieldname');
else
i call my own alert;
end if;
2) No Sir, i cannot define No_ERROR Trigger.

You "can not" create ON-ERROR trigger, or you "did not" create it?

If you didn't, why wouldn't you? There's been an example recently on the board - search for ON-ERROR keyword and you'll even find an example.

Dear Shaheer,

Create an ON-ERROR Trigger for the form module.
now in that trigger , you can write code to show your own error messages.

Eg Code.

declare
itm varchar2(100);
begin
if (MESSAGE_TYPE = 'FRM' and MESSAGE_CODE = '40209')  then
  	itm := get_item_property(name_in('system.trigger_item'),prompt_text);
if upper(itm) = " Prompt text " then
  	message('Please Enter 5 Digit Account Code');
else
        message(sqlerrm);
end if;
else
        message(sqlerrm);
end if;
end;

Don't copy paste the codes.
Try to understand it and in case of any doubt, ask orafaq for clarification.

Regards
Sasi...

What's the purpose of the whole "GET_ITEM_PROPERTY" story? What is

if upper(itm) = " Prompt text " then

supposed to do?

Why not simply (the whole trigger code)

if MESSAGE_TYPE = 'FRM' and MESSAGE_CODE = '40209' then
   message('Please Enter 5 Digit Account Code');
end if;

Hi littlefoot,

FRM 40209 error is
"The value that you entered did not match the format mask on the field."

Here Shaheer just need to set error report for Account code only.
That's why i wote like that.

For example,
there same error will come if user enter some character in a number type field.

so we have to check in which field the error occurred and ned to show appropreate messages.
That's why the code like this.

here i am checking the prompt of the item.
i tried with the item name like this

if :system.trigger_item = :BLOCK_NAME.ITEMNAME then
 message(' Error ');
end if;

but sometimes it doesn't work. that's why i use the prompt name.

Regards
Sasi...

Dear All,

There is a change in the last post..
I wrote the code like

if :system.trigger_item = :BLOCK_NAME.ITEMNAME then
 message(' Error ');
end if;

it is wrong and the correct one is

if :system.trigger_item = BLOCK_NAME.ITEMNAME then
 message(' Error ');
end if;

Sorry for the mistake.

Thanks and Regards
Sasi...

Nope. YOU are wrong.

The correct syntax is

if :system.trigger_item = :BLOCK_NAME.ITEMNAME then

while the wrong syntax is

if :system.trigger_item = BLOCK_NAME.ITEMNAME then

as it produces

Forms

Tabke, View or Sequence reference 'BLOCK_NAME.ITEMNAME' not allowed in this context

Hi littlefoot,

I think there is some misunderstanding.

i shall explain it with an example.

1. My datablock name is BANK
2. ACCOUNTCODE is the item in this block.
3. Now in ACCOUNTCODE field, value entered as 123

Now in the ON-ERROR trigger, I want to check whether the error is occurred with ACCOUNTCODE item.

So my code will be like this

if :system.trigger_item = 'BANK.ACCOUNTCODE' then

and not

if :system.trigger_item = :BANK.ACCOUNTCODE then

In the second case it will check the value of field ACCOUNTCODE , that is 123.

This is what I mean by BLOCK_NAME.ITEMNAME.

Thanks and Regards,
Sasi...

LOL! Right, a major misunderstanding (along with me being sloppy).

if :system.trigger_item = 'BANK.ACCOUNTCODE' then

is OK (i.e. block and item name enclosed into the single quotes).
