How to call sequence in Oracle Forms

Hi,
I am using Oracle Developer Suite 10g. I want to call a sequence that I have created in SQL Plus. When I try to call the sequence in a trigger for a command button (WHEN-BUTTON-PRESSED) the compiler tells me that the sequence cannot be used in this context. I am passing the sequence to a procedure as a parameter. Let me show you some code:
My table is:
Location(loc_id, loc_name);
primary key is loc_id
My sequence is:
CREATE SEQUENCE loc_seq
MINVALUE 1
MAXVALUE 999999
START WITH 1
INCREMENT BY 1
CACHE 20;
My procedure is:
CREATE OR REPLACE PROCEDURE loc_change (v_loc_id IN Location.loc_id%TYPE, v_loc_name IN Location.loc_name%TYPE) AS
BEGIN
INSERT INTO Location(Location.loc_id, Location.loc_name)
VALUES (v_loc_id, v_loc_name);
COMMIT;
END loc_change;
My WHEN-BUTTON-PRESSED trigger is
BEGIN
loc_change(loc_seq.nextval, :DATA_BLOCK.VARIABLE);
END;
All that I need to do is generate a random number for the parameter passed that is the primary key for Location, from within my trigger. Any thoughts?

This
DECLARE
nSeq number;
BEGIN
select loc_seq.nextval
into nSeq
from dual;
loc_change(nSeq, :DATA_BLOCK.VARIABLE);
END;should do the job...
you can also put the fetching of the sequence into the database procedure. if you have DB Version 11g, you can reference the sequence simply by this:
nSeq := loc_seq.nextval;in prior 11g you have to fetch it using select into from dual.

Calling sequence in oracle forms

Hi Experts,
I am working form builder 6i.
Datablock: based on table T_CUST.
Requirement: I want to generate the cust_id through sequence when i am inserting the data.
Could somebody help me how to achieve this and where to write code for this. I have tried the following code:
-- created sequence named cust_seq in scott schema..
-- in 'when-mouse-click' trigger, in forms 6i, I have written code::

Triggers Firing Sequence Of Forms 10g after commit_form trigger.

hi all,
please tell me Triggers Firing Sequence Of Forms 10g after commit_form trigger.

Hi,
I have a doubt regarding the sequence of events when COMMIT_FORM is fired.
Using the following to trigger the event.
DO_KEY('COMMIT'_FORM');
Added debug messages in my form triggers and found that after the ON-INSERT trigger is fired, the WHEN-VALIDATE-RECORD is fired and then the PRE-RECORD.
However this sequence is not specified in the lists of firing sequences mentioned here.
Is it possible to change the sequence programmatically.
In my ON-INSERT trigger, calling a DB procedure to insert row in the table.
Thanks

Forms trigger Firing Sequence

Does anyone know where I can find details on firing sequence of each type of triggers on Item, Block and Form levels?
Can I set the Debugger to trace the actual sequence of firing of triggers at run-time?

(V45) Trigger Execution Sequence in Forms 4.5
=============================================
Introduction
This document lists the order in which triggers fire in Oracle Forms 4.5:
o The first column, Action, describes the function to be performed
(e.g. deleting a record).
o The second column, Trigger Firing Order, describes the order
in which triggers fire after a function is performed.
o The third column, Level, describes the level (form, block, item)
at which the trigger fires. This was accomplished by creating a form
with all the triggers invoked. If a trigger could fire at all levels,
it was included at all levels. Such a trigger fires at the lowest level
at which it is defined.
Key triggers and triggers which fire via buttons or check boxes are
not included.
This bulletin does not cover every contingency and covers only the
most commonly used actions.

Oracle Forms Trigger firing hierarchy flowchart

Greetings,
In 1994, there was a "Oracle Forms Processing Manual" (Oracle part# A11990-2).
This book contained the visual representation of Oracle Forms processes showing where each trigger fires.
Where is this "flow-chart" in documentation available today?
I need to know the explicit chronological sequence of each trigger firing....
Pre-Form trigger fires first...then the When-New-Form-Instance....etc
Thank you for your support!

Sorry.
Let me clarify.
Need to know where it is defined about which trigger fires before or after which other trigger….
The whole sequence…every trigger…
Example:
Document must show stuff like ON-COMMIT fires before(or after) POST-DELETE.
So I am certain that when a delete is initiated by the user, the ON-COMMIT fires before(or after), and so data in the database record is still available(or not available) to the code in the ON_COMMIT trigger.
This helps me know for certain what really happens, step-by-step, when Forms deletes a record.
So the document must show a visual representation of the DELETE EVENT.
This visual representation must explicitly show the ON-COMMIT trigger and the PRE-DELETE trigger and the ON-DELETE trigger and the POST-DELETE trigger…
Thank you!

Bug in Oracle Forms 9i triggers

I've found a bug in oracle forms 9i. It happens when you have a select query inside a when-validate-item trigger and in that query you opt to show an alert when the query has encountered an exception...
When that trigger is fired, the alert will show even if the query returns a record(which means that it does not go through the exception). The solution is to recompile the said trigger.
Is this bug present in the other versions of Oracle forms?
Is there a patch for this bug?

Hi,
Thanks for your reply.
I've consulted with some of my colleagues who have been using Oracle forms for more than 5 years now, and they said that the bug seems to randomly appears...The code works fine in the local environemnt (forms builder) and in the AS itself (compiled in Unix) but after sometime, the bug appears and they just compiled the trigger where the code of the alert is in...
Is there any logical explanation of why compiling a trigger (without changing any code) solves this problem?

DB Trigger firing issue in case of oracle forms session crash

Hi All,
Oracle DB version: Oracle Database 10g Release 10.2.0.2.0 - Production
Oracle Forms version: (Oracle Developer Suite 10g) 10.1.2.0.2 Production
I am entering some data in the oracle forms and committed the data to database. This form is still open.
By some reasons i get a error as "FRM-92101: There is error during forms server startup" and the forms session gets crashed.
When this event happens i wanted to update the records which are inserted before this error occurred. For this purpose i created a BEFORE LOGOFF ON DATABASE trigger (in SYS user) and declared that transaction as autonomous and performed update and then commit.
But when i get this error in forms runtime session, this trigger doesn't fire and also the records don't get updated.
If i query to v$session view, the session entry is gone because the forms session is crashed.
Can anyone please tell me why this trigger don't get fire when oracle forms session gets crashed? Or is there is any other way to run update statement as soon as the forms session gets crashes?
Thanks.

Hi,
please check java runtime console for more issue information.
Windows:
SystemControl->Java Plugin Ver XXXX -> Standard -> Check "Show Java Console"
In Systray, check the console for information about errors in java after the form error.

In Oracle Forms, to run all the When-Validate-Item of all the items at once

In Oracle Forms, is there any built-in / procedure / function which is used to run all the When-Validate-Item triggers of all the Items at once ?
I will put it in detail :
When a form is run and while entering the data..
when we enter some data and try to move out of that item then the When-Validate-Item trigger of that item is fired and the code in that trigger is executed..
Similarly there may be many items and many When-Validate-Item triggers correspondigly in a form..
My requirement is to run all the When-Validate-Item triggers of a form at once when we click a button which is created for that purpose only..
So is there any built-in / procedure / function (to run all the When-Validate-Item triggers of all the items), which can be called in the When-Button-Pressed trigger of that particular button..
If any one having any solution/suggestion, please let me know..
Thanks..

Hi Sandy,
Thanks for your suggestion..
The validations should be done at Item level (When-Validate-Item as usually) and seperately again when a button is pressed.
So to put all the code in another block-level When-Validate-Item trigger or in any When-Button-Pressed trigger will be duplication of the code.
Actually I have around 30 Fmbs to be modified and each Fmb is having around 20 Items and almost all Items are having When-Validate-Item trigger.
So,I wanted to know whether there is any Built-in / Procedure in Oracle Forms which runs all the When-Validate-Item triggers once it is called.
Thanks..

Oracle forms in 10g

Hi,
I am new bee to oracle forms.
I have installed oracle application server in Windows xp.
How to start with from here.
How to create new forms /page /design in oracle 10g
please anyone tell that

Oracle application server (AS) is just a runtime for forms. For creating form you need developer suite.
I use Forms 10g. You can download it from http://www.oracle.com/technetwork/developer-tools/developer-suite/downloads/index.html
The developer suite comes with OC4J - which is some kind of application server emulator, I'd say. But it's ok for developing purposes.
The AS and OC4J must be configured. There are three main files:
* formsweb.cfg
* default.env
* webutil.cfg
That's shortly about AS.
Quick introduction to forms:
1. All data is stored in items, which can be text items, list items, radio buttons, checkboxes, buttons etc. Items are of 2 types: database item (item relates to some table column in database) or non-database item.
2. All items are grouped in data blocks. Block are of 2 types: database block (it's source is DB table, or view, or select clause) and non-database (or control) block.
3. All items are laid out for display on canvases.
4. Canvases are displayed in windows.
Events in forms are called triggers. When event occurs it is said "the trigger is fired". Names for triggers are usually self-explanatory. For instance, when-mouse-doubleclick, when-button-pressed, when-checkbox-changed. There are 3 types of triggers: item level (items can handle those events), block level (block handles the events, items cannot) and form level (form handles the events).
And i think that's all - everything else in Oracle documentation and google.

Form level v/s item level trigger in oracle forms

Hello Experts,
I am new in oracle forms.I am using forms 11g with weblogic server 10.3.5 at windows 7.I am very confused between Form level and item level triggers.What is the sense of use of when-button-pressed trigger at item level & form level.If I have this trigger form level then how could I check that is fired.
Thank You
regards
aaditya

You need to clear you concept first..
Form level Trigger: code applied all respective item within the form
Item level Trigger: code applies for only the item that has the code.
try in a form and you will see the difference.

Migrating Oracle forms and reports from 6i to 10g Application server on Uni

HI Guys,
We are migrating from Oracle forms and reports 6i to 10g.
We will be having application server on Unix box.
I understand following will be the changes i will have to do in this respect -
1. Fonts are to be revisited only Java fonts are supported.
2. Obsolete items, function calls, triggers are to be removed.
My question is since this application can be cross platform application,
Can anyone provide me with changes that I will have to do with configuration files like -
1. Formsweb.cfg,
2. forms.conf
3. default.env
4. registry.dat
Keeping in mind that the application server will be on unix box.
Thanks,
Av.

Java fonts are only supported for the Forms version.
You can use your own fonts for Reports however, there is some legwork to do this. I know because I just went through it.
If you will only being using the PDF output (which for me replaced the Preview mode that existed in 6i), then you have to install the TTF for the missing font, an AFM (use the ttf2pt1 utility to generate the AFM file, but make sure you remove the AFM extension when moving it to Unix). You'll want to use the PDF Subset in the uifont.ali (which exists under the ORACLE_HOME/guicommon/tk/admin directory and add the line underneath the PDF Subset "Font Family Name"="TTF Font Name" The font family name is found when you open the AFM file in textpad or wordpad for the font you generated. This is what you enter. The TTF Font Name is the name the TTF font. You'll have to restart Reports Server after this.
If printing to the printer directly is an option you must have, I will tell you it does not work in Linux right now. You can print to the printer but if the font doesn't exist on the internal memory of the printer, it won't work. There are 3rd party utilities like ORARRP and PDFPrint that can take care of this but, each has its own limitations. The one thing I found with ORARRP is if you generate a Report with an RRPA file extension and open it on Windows, it works great, the printer dialog comes up asking you what printer you want to print too. However, if you call this in Linux/Unix with the filename, it brings it up in the web browser but doesn't prompt you for your printer to print too automatically. So, for me, it's a show stopper. My only other option is to install the fonts on the printer that are missing.
As for the files you want to change, you'll obviously have to make changes to the formsweb.cfg, default.env, forms.conf. I have to modify the reports.sh for some PL/SQL attached libraries to make sure it picks them up. I did have to modify Registry.dat.
There is alot of work but mainly forms wasn't too bad, unless you had fonts that weren't supported. Usually there is another font that you can use to replace the old one but you have to know which fonts exists on the server and try all the keys on the keyboard to find the corresponding keystroke.
Hope this helps.

Problem with inserting new records in Oracle Forms

Hi Friends,
I am a new user to Oracle Forms and I need a help from you people. The problem is as follows:
I have a data block in which I can display a number of records. In this data block the user will be able to edit the fields if no child records are found in another table. I have used when-new-record-instance to attain this scenario. All are text items. One item licensee_id which is made invisible by setting the property in property palette and required=no ( as this is the primary key of the table). Also the audit columns are made invisible.
The code for it is as follows:
DECLARE
     v_alert_button NUMBER;
     v_cnt                          NUMBER;
BEGIN
     SELECT COUNT (*)
INTO v_cnt
FROM id_rev_contracts
WHERE licensee_id = :ID_REV_LICENSEES.licensee_id;
IF v_cnt > 0 THEN
set_item_property('ID_REV_LICENSEES.LICENSEE_NAME', UPDATE_ALLOWED, PROPERTY_FALSE);
ELSE
     set_item_property('ID_REV_LICENSEES.LICENSEE_NAME', UPDATE_ALLOWED, PROPERTY_TRUE);
     -- set_item_property('ID_REV_LICENSEES.LICENSEE_NAME', INSERT_ALLOWED, PROPERTY_TRUE);
END IF;
END;
Now in this data block I should also be able to insert new records and for the same I have used PRE-INSERT trigger and the code for it is as follows:
DECLARE
     v_alert_button NUMBER;
CURSOR v_licensee_id IS SELECT id_rev_licensees_s.NEXTVAL FROM dual;
BEGIN
OPEN v_licensee_id;
FETCH v_licensee_id INTO :id_rev_licensees.licensee_id;
CLOSE v_licensee_id;
IF :id_rev_licensees.licensee_id IS NULL THEN
Message('Error Generating Next v_licensee_id');
RAISE Form_Trigger_Failure;
END IF;
:ID_REV_LICENSEES.created_by := :GLOBAL.g_login_name;
:ID_REV_LICENSEES.last_updated_by := :GLOBAL.g_login_name;
:ID_REV_LICENSEES.create_date := SYSDATE;
:ID_REV_LICENSEES.last_update_date := SYSDATE;
EXCEPTION
WHEN form_trigger_failure
THEN
RAISE form_trigger_failure;
WHEN OTHERS
THEN
v_alert_button :=
msgbox ('ERROR in Pre-Insert - ' || SQLERRM, 'STOP', 'Contact IST');
RAISE form_trigger_failure;
END;
Every thing is compiling fine but at the run time when I am trying to insert a new record I am receiving the following error:
FRM-40508:ORACLE error:unable to insert record
I also think the pre-insert record is not firing at the time of inserting a new record and saving it. So I request you to please delve into this problem and suggest me how to overcome this problem. Code snippets would do more help for me. If you need any other things from me please let me know. I will see if I could be of any help in that concern because I may not be able to send the entire form as it is.
Thanks and regards,
Vamsi K Gummadi.

first of all
pre-insert fires after the implicit/explicit commit/commit_form is issued and before the real insert is submitted to the db.
i would suggest to remove the error handling part for the moment
because i believe you might be getting "ora-xxxx cannot insert null"
and also make visible the primary column to check if the pre-insert is executed.
it would be better to make visible for a while the not null columns of the table/block
i suppose that the block is insert allowed and you are using table as the source of the block and not any procedures or something...
