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.

Is it possible to change trigger firing sequence by program?

Hi,
I would like to know if there is a command like set_item_property or set_block_property or set_lov_property which can allow to change by program a trigger firing sequence. I do not find any, so i think i have to do it manually in property palette of the trigger. Thanks for your answer.

Thx
To change Execution Hierarchy of a trigger, we go into Property palette of that trigger to change this property, i want to know if it is possible to change this property by program without need to go into Property palette of that trigger, EXECUTE_TRIGGER executes an indicated trigger but how to change Execution Hierarchy (for example set_lov_property sets the given LOV property for the given LOV, we use set_lov_property in the program and do not need to go into property palette of this lov), hope you understand what i would like to do. thanks for your help.

Sequence Names And Triggers

I am trying to link my sequences with my triggers. I have looked in sys.obj$, sys.seq$ and sys.trigger$ but the obj# doesn't match in triggers and seq$.
What I am trying to do is write a script that will update the sequences to the max vaule in a table. I have 125+ seqences and do it by hand will not work. I can get the max value but then I need to create or replace the sequence with the new one I don't just want to updated it.

Have you looked at dependencies$ or the dba_dependencies view? It should provide information about the trigger dependencies including the sequences.
Hope this helps.
Janet.

Altering the firing sequence of triggers

Hi,
I have some block level and form level triggers.In excution time block level fires first and then the form leval.
My requirement is to alter the firing of triggers means form level first and then the block level.
Urgent Plz help me
regards
& thanx in advance
vani

Try playing around with the execution hierarchy of the trigger's property.
you may override the Form level trigger with the block level but I don't think you can reverse them, unfortunately I don't have Forms installed on the machine I am now to test it.
Try it

Sequence of variables triggered while running a query

Hi All,
Can anyone please let me know the sequence with which the (Customer exit) variables in CMOD are executed.
I mean in the Processing step 2 where we have a statement
Case Varnam what is the varaible sequence which enters into this statement.
Regards
Ganesh

My actual issue is :
We have 2 queries
1. First query speaks about sales Actual vs Planned
and in this query we have the KF retricted by time period(Customer exit var) & 0INFOPROV(Customer exit var).
2.Second speaks about Profits for Actuals Vs Planned
and in this query also we have the KF retricted by time period(Customer exit var) & 0INFOPROV(Customer exit var).
when we execute query 1(In Debug mode in CMOD under the Processing step 2 I can find that the CASE I_VARNAM catches first the Time period and then for 0INFOPROV but when I run query 2 exactly the vice versa happens i.e the varname first catches for 0INFOPROV n then for Time period. So I just want to know how is the sequence of this customer exit variables defined/cached in CMOD under Processing step 2 maintained.
Please can any one let me know the solution at the earliest

Sequence numbers and triggers

We want to insert rows into a target table. The target table would have a sequence number that is populated on insert.
We want to create a "Before Insert" trigger that would check a table on a second instance across a DBLink. The trigger would check the natural key.
If the natural key exists, then a previously assigned surrogate ID would be used on the inserted row instead of the sequence number and the sequence number would not be incremented or used. If the natural key does not exist, then the sequence number would be incremented and used.
The question I have is: When is the sequence number resolved? Can we override the sequence number as outlined?

Trigger Firing Sequence?

Hei Guys
I have a form where I have a date and time field(text fields). I have a OK/SAVE button, which is subclassed, and executes do_key(commit_form), which in turn executes form level key-commit trigger. On the key-commit trigger, I have some program units, which basically validate the form, and then commit the form.
On the time field, if I change the time(which the system calculated when I hit a button), I do some validation in the when-validate-item of the field.
The code in the time text-fields, when-validate-item is as follows.
fp_check_time(:BL_COMPLAINT.APPT_TIME);
declare
     lnu_error number;
     alrt_id alert := find_alert('AL_CONFIRM');
     some_number number;
begin
     --some_number := fpkg_error_handler.fp_message('UEM','0000','ERROR','@when-validate APPT_TIME');
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_true);
     if :BL_COMPLAINT.APPT_time <> nvl(:parameter.APPT_TIME, '*')     then
set_alert_property(alrt_id, alert_message_text, 'You have changed the system recommended date. This could lead to double booking. Do you want to continue ?');
if show_alert(alrt_id) = ALERT_BUTTON1 then
if spkg_med_schedule.sf_chk_valid_datetime
          (:BL_COMPLAINT.SICK_CALL_SERVICE_GROUP,
'1',--check nurse
:parameter.p_clinic,
:BL_COMPLAINT.APPT_DATE,
:BL_COMPLAINT.APPT_time) = 'N' THEN
     lnu_error := FPKG_ERROR_HANDLER.FP_MESSAGE('UEM','0000','ERROR','The date/time you have selected is not valid. Please change the date/time.');
     :BL_COMPLAINT.APPT_TIME := :parameter.APPT_TIME;
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_false);
      raise form_trigger_failure;
end if;
else
          some_number := fpkg_error_handler.fp_message('UEM','0000','ERROR','@when-vaidate APPT_TIME not ab1');
     :BL_COMPLAINT.APPT_TIME := :parameter.APPT_TIME;
--     :parameter.error_occur := 'TRUE';
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_false);
     raise form_trigger_failure;      end if;
end if;
end;
I have this code even in the date field. which is also a text item.
I am hoping you might have noticed, a couple of Raise form_trigger_failure in the code. But, the processing, does not stop there and continues processing and tries to commit the form.
[b1.]Why does that happen?

> continues processing and tries to commit the form
It would help if you would describe what you mean by "tries to commit". What does the form do?
The first thing you need to do in your commit processing sequence is:
Validate(form_scope);
If not form_success then
    Raise form_trigger_failure;
End if;The above code will stop the commit if an edit error occurs. If you don't validate and check for success, commit processing continues, and you will probably get multiple error messages popping up before the commit process finally stops.

Triggers in Oracle

Hi,
I have a question about the behavior of triggers. Consider the following situation:
1. There is a table called TABLE_A.
2. There is a table called TABLE_B.
3. There is a trigger T1 that watches TABLE_A for inserts, and if there is an insert the trigger inserts a row into TABLE_B.
4. There is a trigger T2 that watches TABLE_A for inserts, and if there is an insert the trigger inserts a row into TABLE_B.
5. There is a trigger T3 that watches TABLE_B for inserts, and peforms some action.
6. There is a trigger T4 that watches TABLE_B for inserts, and peforms some action.
My questions are:
1. What is order in which these triggers will execute when a row is inserted into TABLE_A?
2. Will any of the triggers run concurrently (perhaps in different threads?) ?
3. Is the order which triggers run predictable?
4. Is there any way to define priority, synchronous, concurrent behavior with the triggers?
5. Is there any way to define dependency among triggers (e.g. T1 cannot run until T2 finishes running) ?
Thanks in advance,
Galen

Sounds like you're looking for the control offered by different types of triggers, row level vs. statement level triggers. Here is what Oracle Concepts has to say about Trigger execution:
A single SQL statement can potentially fire up to four types of triggers:
BEFORE row triggers
BEFORE statement triggers
AFTER row triggers
AFTER statement triggers
A triggering statement or a statement within a trigger can cause one or more integrity constraints to be checked. Also, triggers can contain statements that cause other triggers to fire (cascading triggers).
Oracle uses the following execution model to maintain the proper firing sequence of multiple triggers and constraint checking:
Run all BEFORE statement triggers that apply to the statement.
Loop for each row affected by the SQL statement.
Run all BEFORE row triggers that apply to the statement.
Lock and change row, and perform integrity constraint checking. (The lock is not released until the transaction is committed.)
Run all AFTER row triggers that apply to the statement.
Complete deferred integrity constraint checking.
Run all AFTER statement triggers that apply to the statement.
The definition of the execution model is recursive. For example, a given SQL statement can cause a BEFORE row trigger to be fired and an integrity constraint to be checked. That BEFORE row trigger, in turn, might perform an update that causes an integrity constraint to be checked and an AFTER statement trigger to be fired. The AFTER statement trigger causes an integrity constraint to be checked. In this case, the execution model runs the steps recursively, as follows:
Original SQL statement issued.
BEFORE row triggers fired.
AFTER statement triggers fired by UPDATE in BEFORE row trigger.
i. Statements of AFTER statement triggers run.
ii. Integrity constraint checked on tables changed by AFTER statement triggers.
Statements of BEFORE row triggers run.
Integrity constraint checked on tables changed by BEFORE row triggers.
SQL statement run.
Integrity constraint from SQL statement checked.
There are two exceptions to this recursion:
When a triggering statement modifies one table in a referential constraint (either the primary key or foreign key table), and a triggered statement modifies the other, only the triggering statement will check the integrity constraint. This allows row triggers to enhance referential integrity.
Statement triggers fired due to DELETE CASCADE and DELETE SET NULL are fired before and after the user DELETE statement, not before and after the individual enforcement statements. This prevents those statement triggers from encountering mutating errors.

Triggering Sequence

Hi friends
Please tell me the firing sequence of trigger,
becoz i can't able to use the correct sequencing of trigger,
which will fire first PREUPDATE TRIGGER OR WHEN NEW RECORD INSTANCE,
since is using this trigger in forms customization, when i query the forms in apps
i confuse which is triggering first

This is not the correct forum for apps. You can ask your question in apps forum.
For the triggers when-new-record-instance will fire first then pre-update.
If when-new-record-instance trigger in block level and you are enter into a item then it will fire for every record but the ptr-update will fire when u will commit that time pre-update will fire if there are any changed data in the form.

Before or After Triggers

Hi,
I have a doubt on functioning of Before or After Triggers.
Here is an example of it:
I created a trigger on EMP table
create or replace trigger tri11 before insert or update or delete on emp for each row
begin
if to_char(sysdate,'dy')='fri' then
raise_application_error(-20101,'No Transactions should be happend on Friday');
end if;
end;
According to the trigger created it has to fire before any event is happening and it should not allow any insertions or updates or deletion on FRIDAY.
And that is working fine.
I changed the trigger to fire on After Insert or update or delete....
create or replace trigger tri11 after insert or update or delete on emp for each row
begin
if to_char(sysdate,'dy')='fri' then
raise_application_error(-20101,'No Transactions should be happend on Friday');
end if;
end;
Here according to this trigger it has to fire after any event is happening .....but still it is not allowing me to perform any insertions or updates or deletion on FRIDAY.
And showing me the error message as below:
SQL> update emp set sal = 11000;
update emp set sal = 11000
ERROR at line 1:
ORA-20101: No Transactions should be happend on Friday
ORA-06512: at "SCOTT.TRI11", line 3
ORA-04088: error during execution of trigger 'SCOTT.TRI11'
Can anyone please explain me the difference.
Thanks.

All triggers must be fired synchronously with the triggering statement. The statement and all triggers that are fired as the result of the statement must be atomic-- they must all succeed or all fail. It doesn't matter whether it is a before or after statement trigger that throws the exception-- in either case, the entire statement will fail and thus be rolled back.

How to find out which sequence a certain column used?

you konw column C in table T is created by a sequence.
How to find out which sequence column C is using?

In the meantime I think it ought to becompulsory to
only assign sequence values in triggers.
Why? I can see no good reason for this. I think it's a good idea to have stuff like this
coded in only one placeI don't like your argument for compulsory using triggers for sequences for exactly the same reason as you, ie that I like to keep my code in one place. If I'm reading some pl/sql code which uses a sequence I like to see the fact that the sequence is used in the pl/sql code, rather than to check to see if theres a trigger on the table and then see which sequence that uses.
"naming conventions can work, provided they're enforced. Alas, like other standards, they can only be enforced by active policing".
Thats what code reviews are.
" there is also the special case of one sequence populating more than one table...."
This is My Pet hate. I don't think there's ever a case where this is absolutely necessary. Again code reviews
Unfortunately I have to live with a system which does this.
and I appreciate we can't all have code reviews, etc.

Sequencing and Trigger on Oracle 9i lite database

We created a schema (TESTSCHEMA) on Oracle 8.1.7 Enterprise edition and have a created a trigger which will use the sequence object to generate primary key for the table (TEST_TABLE)
Sequence creation:
CREATE SEQUENCE TESTSCHEMA.TEST_TABLE_SEQUENCE START WITH 6000 INCREMENT BY 1 MINVALUE 6000 MAXVALUE 6999 NOCACHE NOCYCLE NOORDER ;
Trigger creation:
CREATE OR REPLACE TRIGGER TEST_TABLE INSERT BEFORE INSERT ON TEST_TABLE FOR EACH ROW
DECLARE
pkValue NUMBER;
BEGIN
pkValue := 0;
Select TEST_TABLE_SEQUENCE.NextVal into pkValue from dual;
:NEW.TEST_KEY := pkValue;
END TEST_TABLE_INSERT;
We have created a snapshot of the schema on mobile server, synchronized the data with the client (Win32 for testing purpose).
The trigger works fine on the server, but when I run the same query on the lite database with msql it gives me an error:
[POL-3221] null key in primary index
I was wondering if Sequence generation and Triggers are supported on Oracle 9i lite database ? Or am I missing out something ??
Any information/ help is appreaciated
Thanks
Neeraj

You can't use SAVEPOINT / ROLLBACK TO SAVEPOINT statements in the database trigger:
ORA-04092: cannot SET SAVEPOINT in a trigger
ORA-04092: cannot ROLLBACK in a trigger
I am not sure what you need exactly, but you can try this:
