Instead of Update Trigger error

Hi all,
I've been trying to solve this issue from past 4 to 5 days..I am unable to solve...Can someone please help....
I hhave a requirement in which I need to update 4 tables from a single form...I created a view which will get the required fields along with the primary keys from all these 4 tables.
Then I created a Instead of Update trigger as below
CREATE OR REPLACE TRIGGER "HOMEPAGEVIEW_UPDATE"
INSTEAD OF UPDATE ON cts_homepageview
BEGIN
DECLARE
vID NUMBER;
UPDATE cts_hardware_info
SET STATUS_ID = :NEW.STATUS_ID,
COMPUTER_NAME = :NEW.COMPUTER_NAME,
OPERATINGSYSTEM_ID = :NEW.OPERATINGSYSTEM_ID
where computer_id = :NEW.COMPUTER_ID;
UPDATE cts_server_administrator
SET PRIMARY_ADMIN_ID = :NEW.PRIMADMIN_ID,
SECONDARY_ADMIN_ID = :NEW.SECONDADMIN_ID
WHERE ID = :NEW.ID;
UPDATE cts_location_info
SET BUILDING_ROOM_RACK = :NEW.BUILDING_ROOM_RACK
WHERE LOCATION_ID = :NEW.LOCATION_ID;
UPDATE cts_maintenace_info
SET MAINTENANCE_WINDOW = :NEW.MAINTENANCE_WINDOW
WHERE MAINTENANCE_ID = :NEW.MAINTENANCE_ID;
END;
When I try to update a record, am gettting the following error
ORA-20505: Error in DML: p_rowid=488, p_alt_rowid=COMPUTER_ID, p_rowid2=, p_alt_rowid2=. ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc.
Error Unable to process row of table CTS_HOMEPAGEVIEW.
OK
I have already posted this question on the forum, but dint get any replies so trying my luck again....Can someone plzzzzzz help...I searched on ths forum for similar requests...Found one post bt hte solution wasnt given...
Thanks,

Hi Varad and Andy,
Thank you both for your responses first..I was soo tensed since no one replied to my previous post fr 5 days..
Varad,
With the change Andy told ('Begin & END'), I tried in SQL Workshop updated computer_name (of cts_hardware_info) data in the view..It updated the data. But from the form, it is still giving the same error.
Andy,
Here is my view.. All the table are associated with the cts_hardware_info using computer_id. And using this computer_id I have put all the data together.

ApEx 4.1.1: update record in a view with 'instead of update' trigger

I created a form against a view. The view is complex enough which prevents direct updates. To incorporate the update logic I created an 'instead of update' trigger on the view. When I open up the form, do changes, and click 'Apply Changes' button I am getting the following exception
ORA-02014: cannot select FOR UPDATE from view with DISTINCT, GROUP BY, etc.
I understand that the standard 'Automatic Row Processing' process is trying to lock the record before updating using a cursor like
select *
from my_view
for update
and fails. Is it possible to bypass this locking while using the standard APEX processes?
I think I can create a custom PL/SQL process which would execute the UPDATE statement (at least, it works in SQL*Plus), but I would like to know if I can use a standard ApEx functionality for this.

Hello,
Sorry for delay.
I had found a feedback about trigger issue when restore SQL Database from a BACPAC file. Microsoft said the fixed will be available in the next major release of DacFx.
Feedback:
SQL Azure fires a trigger when restoring from bacpac
You can refer to the workarounds in the feedback. For example, if there is small amount of triggers on the database, you can try to remove the triggers and then recreate when restore from bacpac file.

Instead of update trigger

Hi
I have a view, I like to create a update form for.
Someone have a sample how to use a "instead of update trigger" with a form?
I would like to have a report with a column link to the form, and the form use a "instead of update trigger" to update the row.
Best Regrads
Jesper Vels

Hi Jesper,
I'm not sure I understand your problem correctly but I'll have a go nevertheless.
I think you can accomplish this with standard out of the box apex functionality. 
You can create your report with a link to your data entry form which has auto DML functionality built in. I do not understand the need for an update trigger, based on what you have said. 
I think this link will give you an idea how how to accomplish the functionality your looking for.
Otherwise In version 2.0 (the only version I have access to at the moment - though should be the same in 2.2). Create a new page of type form and specify "Form on a Table with Report" in the next stage of the wizard. Work through the rest of the wizard and see whether what is generated fits your purpose or can easily be adapted to suite your purposes. 
Let me know how you get on.

- Raise an error
- Do nothing (i.e. do not update any data in any table)
That is a syntactically valid state-- Oracle will certainly allow you to have an INSTEAD OF UPDATE trigger that effectively throws away update statements. It's just that it would be rather rare that this would be the desired behavior. Presumably, if you're going through the effort of writing the trigger, you want certain update statements to succeed and, thus, to update data. If that is the case, your trigger would have to have UPDATE statements that update the proper row(s) in the proper base table(s).
An INSTEAD OF UPDATE trigger is literally that. You are replacing, in its entirety, the update statement against the view with the code in your trigger. So your trigger would need to issue the base table updates that Oracle would have had there not been a trigger on the view.

alternatively,
what happens if you modify from person@oraclelink in

Instead of Trigger Error

Hi ALL,
I am trying to create INSTEAD OF trigger on the existing VIEW, but I getting error as:-
Not found
The requested URL /apex/wwv_flow.show was not found on this server
I'm creating trigger as :-
CREATE OR REPLACE TRIGGER "trigger_name"
INSTEAD OF UPDATE ON "view_name"
FOR EACH ROW
BEGIN
UPDATE query;
UPDATE query;
END;
but when I'm writting only one update query rather two update queires in the above trigger, it is creating but not with two update queries.
Also I created another INSTEAD OF trigger on the same View as:-
CREATE OR REPLACE TRIGGER "trigger_name"
INSTEAD OF INSERT ON "view_name"
FOR EACH ROW
BEGIN
INSERT query;
INSERT query;
END;
this trigger is created without any errors than why INSTEAD OF(FOR UPDATE) trigger is not creating.... can anybody help me out with this issue.....

Hi again,
everything is working very much fine(I mean instead of trigger with update as well as with insert) when I'm creating on apex workspace.... this is the issue with my development enviornment.... so this is the problem with development DB or something else?????

DB Trigger error - Updating same table in the trigger script

Hi All,
I have a table tab1, when ever any update is done on this table on column col1 then col2 also need to get update.(These are linked to forms so user can update only col1 from form frontend)
so I created a trigger as follows.
CREATE OR REPLACE TRIGGER tri1
AFTER UPDATE
ON tab1
FOR EACH ROW
WHEN (NEW.col1 = 'YES')
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
UPDATE tab1 SET col2= 1
WHERE transaction_id = :OLD.transaction_id;
COMMIT;
END;
When there is any update on this table I get following error. Please let me know if I miss any thing.
ORA-00060: deadlock detected while waiting for resource
ORA-06512: at "user1.tab1", line 5
ORA-04088: error during execution of trigger 'user1.tab1'
Please let me know if I am not clear. Thanks
Edited by: DharV on Aug 23, 2011 5:17 AM

Is your transaction_id unique?
If that is the case then you could perhaps use BEFORE UPDATE instead of AFTER UPDATE:
CREATE OR REPLACE TRIGGER tri1
BEFORE UPDATE
ON tab1
FOR EACH ROW
WHEN (NEW.col1 = 'YES')
BEGIN
:NEW.col2 := 1;
END;If your transaction_id is not unique - so you really want to update more than one row in tab1 - your update cannot update the same row as the trigger reacted upon, even with the use of autonomous transaction. Then you could combine the above BEFORE UPDATE trigger with your own AFTER UPDATE, but then add ROWID != :OLD.ROWID to the where clause, but it would be a bad idea because some of your rows will be updated in one transaction and others in another transaction.
In general autonomous transaction is not a great way to solve mutating table problem in a trigger. Hopefully you have a unique transaction_id and can do BEFORE UPDATE - if not then a better way is to save the id's to be updated in a package array in the FOR EACH ROW triggers, and then do a AFTER UPDATE trigger that is NOT "for each row" to update the list of saved id's.

Mutating Trigger error while updating table

Hi Guys,
I am updating one table and after trigger also fire at the same time. Now, I want to avoid mutating trigger error. Can any one help me on this.
Thanks in advance!
Regards,
-LRK

You'll have to read these articles first, they explain what's the problem and how to deal with it:
http://www.oracle-base.com/articles/9i/MutatingTableExceptions.php
http://asktom.oracle.com/pls/asktom/ASKTOM.download_file?p_file=6551198119097816936
but, as Saubhik already said, using Oracle's AUDIT functionality would be the way to go.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4007.htm
Using an autonomous transaction can result in corrupted data or unexpected errors, stay away from them if you want to use them in order to bypass/hide your mutating table error.

Update trigger fails with value too large for column error on timestamp

Hello there,
I've got a problem with several update triggers. I've several triggers monitoring a set of tables.
Upon each update the updated data is compared with the current values in the table columns.
If different values are detected the update timestamp is set with the current_timestamp. That
way we have a timestamp that reflects real changes in relevant data. I attached an example for
that kind of trigger below. The triggers on each monitored table only differ in the columns that
are compared.
CREATE OR REPLACE TRIGGER T_ava01_obj_cont
BEFORE UPDATE on ava01_obj_cont
FOR EACH ROW
DECLARE
v_changed boolean := false;
BEGIN
IF NOT v_changed THEN
    v_changed := (:old.cr_adv_id IS NULL AND :new.cr_adv_id IS NOT NULL) OR
                 (:old.cr_adv_id IS NOT NULL AND :new.cr_adv_id IS NULL)OR
                 (:old.cr_adv_id IS NOT NULL AND :new.cr_adv_id IS NOT NULL AND :old.cr_adv_id != :new.cr_adv_id);
END IF;
IF NOT v_changed THEN
    v_changed := (:old.is_euzins_relevant IS NULL AND :new.is_euzins_relevant IS NOT NULL) OR
                 (:old.is_euzins_relevant IS NOT NULL AND :new.is_euzins_relevant IS NULL)OR
                 (:old.is_euzins_relevant IS NOT NULL AND :new.is_euzins_relevant IS NOT NULL AND :old.is_euzins_relevant != :new.is_euzins_relevant);
END IF;
[.. more values being compared ..]
    IF v_changed THEN
    :new.update_ts := current_timestamp;
END IF;
END T_ava01_obj_cont;Really relevant is the statement
:new.update_ts := current_timestamp;So far so good. The problem is, it works the most of time. Only sometimes it fails with the following error:
SQL state [72000]; error code [12899]; ORA-12899: value too large for column "LGT_CLASS_AVALOQ"."AVA01_OBJ_CONT"."UPDATE_TS"
(actual: 28, maximum: 11)
I can't see how the value systimestamp or current_timestamp (I tried both) should be too large for
a column defined as TIMESTAMP(6). We've got tables where more updates occur then elsewhere.
Thats where the most of the errors pop up. Other tables with fewer updates show errors only
sporadicly or even never. I can't see a kind of error pattern. It's like that every 10.000th update
or less failes.
I was desperate enough to try some language dependend transformation like
IF v_changed THEN
    l_update_date := systimestamp || '';
    select value into l_timestamp_format from nls_database_parameters where parameter = 'NLS_TIMESTAMP_TZ_FORMAT';
    :new.update_ts := to_timestamp_tz(l_update_date, l_timestamp_format);
END IF;to be sure the format is right. It didn't change a thing.
We are using Oracle Version 10.2.0.4.0 Production.
Did anyone encounter that kind of behaviour and solve it? I'm now pretty certain that it has to
be an oracle bug. What is the forum's opinion on that? Would you suggest to file a bug report?
Thanks in advance for your help.
Kind regards
Jan

Could you please edit your post and use formatting and tags. This is pretty much unreadable and the forum boogered up some of your code.

Mutating error : row level BEFORE UPDATE trigger

Hi,
I had an issue on mutating terror(was trying to write a row level BEFORE update trigger), however i got it resolved after refering tom kytes web site. I thought i would share it with everyone, might be helpful for a few... Thanks!
I will be more than happy to learn on further better ways of resolving this issue.

Instead of delete trigger rows deleted

Hi All.
Im using a few instead of triggers over a view. The view selects data from other tables and merges them together. This view essentially forms the parent of a few one2one relationships with other tables.
However my application doesnt know its a view (im using hibernate orm framework) - so when I delete this object which is mapped to a view, I get an error saying that no records where deleted. Also, if i test in sqlplus, i get "0 rows deleted" in response to a delete - which of course is true, but i want it to say 1 or some number of my choice.
How can i modify my "instead of delete" trigger so that the number for records deleted count returned to caller is 1, or some number i can define?
Here is my current trigger...
create or replace
trigger product_view_delete_trigger
instead of delete
on product_view1
for each row
begin
null;
end;
Thanks.

In regards to why Im using a view - its discussed here...
Crazy Union across 3 tables
The view im using is not updatable - it uses a union. I use "instead of triggers" to trick my application into thinking its a real table which is insertable. And this works fine.
Im having trouble tricking my application into think that the delete was successful, because the "instead of delete" trigger doesnt actually delete anything - which is what i wnat - but i want it to report back to the caller that a delete occurred.
I want the SQL%ROWCOUNT to be set to 1 or whatever. Perhaps this is not hte variable, but im hoping there is some variable I can set which is used to report back to the client as to how many records were deleted.
thx.

Halting the update from a BEFORE UPDATE trigger

Hello,
I'm writing a trigger which is set to fire before update. One of the possible scenarios requires that the row being updated is not updated but instead deleted. Is it possible to send a DELETE query and then stop the update process so it doesn't spit out an error? I haven't tested this yet, but I'm quite sure it will give an error if it's trying to update a row which has just been deleted.
Thanks,
Pavel

Hi,
Personally, I don't like implement some business logic into trigger... so, why run an update whenever you need a delete ?
I would modify the original code to delete in this case instead of update.
My 2 cents,
Nicolas.
