Error in after insert trigger

Hello all,
I have a question about after insert trigger. Will be new row inserted and commited if after insert trigger returns error? Thank you.
regards,
Miha

What is the error that u r facing?
there could multiple reasons for that. Basically, u can't put commit in the trigger (unless it is an autonomous transaction). Share the pseudo-code of u r triiger, so that , problem can be identified.

Using Database Change Notification instead of After Insert Trigger

Hello guys! I have an after insert trigger that calls a procedure, which in turn is doing an update or insert on another table. Due to mutating table errors I declared the trigger and procedure as autonomously transactional. The problem is, that old values of my main tables are inserted into the subtable since the after insert/update trigger is fired before the commit.
My question is how can I solve that and how could I use the change notification package to call my procedure? I now that this notification is only started after a DML/DDL action has been commited on a table.
If you could show me how to carry out the following code with a Database Change Notification I'd be delighted. Furthermore I need to know if it suffices to set up this notification only once or for each client seperately?
Many thanks for your help and expertise!

Sebastian

It looks like you have an error in line 37 of your code. Once you fix that the problem should be resolved.

Before or After insert trigger on HR_API_TRANSACTION_VALUES

I am on the termination page of SSHR and after entering the details when clcked on 'Next' the validations built in before / after insert trigger of HR_API_TRANSACTION_VALUES does not retrieve the data and the error 'No data found' is displayed.
We do not have AME approval. When clicked on 'Next' it goes to the review page. When I do a select on the HR_API_TRANSACTION_VALUES the data do exists but the validation does not work.
We have Oracle HRMS 11i with database as 11g.
Please give a resolution at the earliest.

you can use
hr_transaction_api.set_varchar2_value
or
hr_transaction_api.set_number_value
based on what type of value that you want to update

After Insert Trigger with DML on the subject table?

I am trying to set up e-mail notifications, so I created a procedure, which accepts the argument of an id. In the procedure, it queries the table and sends out mail based on the result set. (in the trigger, I pass in the value of :NEW.id). The procedure then queries the table for that row id.
First, for the after update I was getting the error:
ORA-04091: table is mutating, trigger/function may not see it ORA-06512
So, I was advised to do in the declare block: pragma autonomous_transaction; I did that, and that solved the problem there. SO I did the same in the after insert trigger, but then I get the error:
ORA-00060: deadlock detected while waiting for resource ORA-06512
I asked our DBA and he said you are not able to query the table of which the trigger is a subject of. I thought it would be possible since its After insert or update?
Can anyone offer any suggestions ? :)
Thanks,
Trent

Any reason why it would work in an after update trigger then?
So, I was advised to do in the declare block: pragma autonomous_transaction; I did that, and that solved the problem therePRAGMA AUTONOMOUS_TRANSACTION "bends" the restriction against SQL against base table.
It is the equivalent to tap dancing across a mine field.
You might get the desired results most of the time or you might get a tasty surprise when you least expect it.
What happens to your application in the future, if/when the UPDATE has a ROLLBACK issued & PRAGMA AUTONOMOUS_TRANSACTION has successfully completed?
Inquiring minds would like to know the answer.

After insert trigger

Dears,
In after insert trigger implementation if the base table failed due to some errors.
Is it possible to still have records inserted in the log table inside the trigger
Thanks
Janani.C

What you want is to write log records to a table, regardless of whether the transaction they're logging fails. This would make sense for inevstigating errors,e tc. This is the only time when it is acceptable to use autonomous transactions.
Encapsulate your logguing code in a separate procedure which has the {font:courier new}PRAGMA autonomous_transaction{font} in its declaration, and include a commit. Such a procedure works in its own separate tranasction - a separate session in fact - and write the log record without affecting the broader transaction.

Cheers, APC
P.S. I agree with Hoek that you should investigate teh LOG ERRORS INTO functionality, as it can be very useful, especially with bulk processes. However, it can only store information directly relating to the rejected records, which might not be sufficient for your purposes.

After insert trigger issue

Hi All,
Can I have an after insert trigger on a table wherein the execution is also on the same table?
It's like 10 columns in the table A.
During a new row insertion, except one specific column(say 'J'), remaining all getting data.
Now 'after insert', need to update the data of the column J based on one inserted value for column say ID.
Code goes like below:
CREATE OR REPLACE TRIGGER UPDATE_J
AFTER INSERT ON A REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
begin
if :new.ID = 'N%' then
     :new.J:= 'N';
else
     :new.J:= 'M';
end if;
end;
Below is the error when I tried to execute that.
ORA-04091: table string.string is mutating, trigger/function may not see it
Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
Action: Rewrite the trigger (or function) so it does not read that table.
Any idea to resolve?
Regards,
Seetharaman.

Hi,
The docs say
Restrictions on AFTER
      An AFTER row trigger or AFTER row section of a compound trigger can only read but not write into the :OLD or :NEW fields. When faced with problems like this, it is always a good thing to consult the documentation.
Regards
Peter

Update by after insert trigger

I need to update each new inserted row of data by checking if there were same values in the table. So I tried the After Insert Trigger with the code below :
CREATE OR REPLACE TRIGGER approve_checker
after insert on TBL_BILL
for each row
declare
counter integer;
begin
SELECT COUNT() INTO counter FROM TBL_BILL WHERE issue_date=:NEW.issue_date AND wagon_no=:NEW.wagon_no ;*
IF( counter > 1)
THEN
UPDATE TBL_BILL SET approved = 2 WHERE id = :NEW.id;
END IF;
end approve_checker;
But errors accured :
ORA-04091: table RAIL.BILL is mutating, trigger/function may not see it
ORA-06512: at "RAIL.APPROVE_CHECKER", line 4
ORA-04088: error during execution of trigger 'RAIL.APPROVE_CHECKER'
Any help appreciated.

You cannot SELECT from the table on which the row-level trigger is defined, nor can you UPDATE a table on which the row-level trigger is defined. If you are inserting multiple rows in a single INSERT statement, Oracle can't be sure what rows to update and/or select.
Is there a reason that you wouldn't just create a unique constraint to enforce this condition?

Calling of Stored Procedure in After Insert Trigger

Can I call a Stored Procedure in After Insert Trigger ?
Please send a sample code (good example) of After Insert Trigger.
Thanks.

Kishore,
I have two table WLCS_ORDER, WLCS_ORDER_LINE
WLCS_ORDER - It holds order header information like
ORDER_ID
CUSTOMER_ID
TRANSACTION_ID
STATUS
ORDER_DATE
SHIPPING_METHOD
SHIPPING_AMOUNT
SHIPPING_CURRENCY
PRICE_AMOUNT
PRICE_CURRENCY
SHIPPING_GEOCODE
SHIPPING_STREET1
SHIPPING_STREET2
SHIPPING_CITY
SHIPPING_STATE
SHIPPING_COUNTRY
SHIPPING_POBOX
SHIPPING_COUNTY
SHIPPING_POSTAL_CODE

WLCS_ORDER_LINE - It holds all order lines information like
ORDER_LINE_ID
QUANTITY
PRODUCT_ID
TAX_AMOUNT
TAX_CURRENCY
SHIPPING_AMOUNT
SHIPPING_CURRENCY
UNIT_PRICE_AMOUNT
UNIT_PRICE_CURRENCY
MSRP_AMOUNT
MSRP_CURRENCY
DESCRIPTION
ORDER_ID
TOTAL_LINE_AMOUNT
Relation between WLCS_ORDER, WLCS_ORDER_LINE is one to many.
For each WLCS_ORDER row, one or more order lines will insert into WLCS_ORDER_LINE table.
For each new row in WLCS_ORDER table, I have to update the following columns in both the tables with my maths.
WLCS_ORDER
shipping_amount
price_amount
order_subtotal
WLCS_ORDER_LINE
shipping_amount
I thought I can do this in after insert trigger, But if it is not possible, Please give the best way to fulfill this requirement.
I appreciate your help.
Have a great day.

After insert trigger with :NEW.ROWID

Hi All,
I am using a After insert trigger to generate history record as following:
CREATE TABLE TB_TEST (classID number(3), classNm varchar2(12));
CREATE TABLE TB_HIST_TEST (hist_dttm timestamp(6), classID number(3), classNm varchar2(12));
CREATE or REPLACE TRIGGER air_test AFTER INSERT ON tb_test FOR EACH ROW
BEGIN PK_SRVC.CRT_NewRec('TB_TEST', 'TB_HIST_TEST', :new.ROWID); END:
In PK_SRVC package, I use the following statment to create new record in TB_HIST_TABLE:
     Insert into tb_hist_test (hist_dttm, classID, classNm)
     values (select systimestamp, classID, classNm from tb_test where rowid = ROWID )
The trigger DOES fire when a new row is inserted into TB_TEST. However there is no record inserted into TB_HIST_TEST. Any suggestion?
Thanks,

The PK_SRVC.CRT_NewRec is a generic service package that can be shared by many tables. It uses dynamic SQL to get all the collumns for different tables based on USER_TAB_COLUMNS. The following is the code of this package:
PROCEDURE CRT_NewRec ( p_TableName IN VARCHAR2, p_AudTableName IN VARCHAR2, p_RowID)
IS
       TYPE TabCol_RecTyp IS RECORD (COLUMN_NAME VARCHAR2(30), COLUMN_ID NUMBER);
       TYPE TabCol_CurTyp IS REF CURSOR;
        c_TabCol TabCol_CurTyp;
        rc_TabCol TabCol_RecTyp;
        v_Sql_TabCol VARCHAR2(1000);
        v_ColNames VARCHAR2(1000);
        v_Sql VARCHAR2(1000);
        PRAGMA AUTONOMOUSE_TRANSCATION;
BEGIN
        v_SQL_TabCol := ' SELECT column_name, column_id FROM USER_TAB_COLUMNS'
                                  || ' WHERE table_name = ' || CHR(39) || p_TableName || CHR(39)
                                  || ' ORDER BY column_id';
        v_ColNames := NULL;
        OPEN c_TabCol FOR v_Sql_TabCol;
        Loop
               FETCH c_TabCol INTO rc_TabCol; Exit WHEN c_TabCol%NOTFOUND:
               v_ColNames := v_ColNames || ',' || rc_TabCol.COLUMN_NAME;
        End Loop;
        CLOSE c_TabCol;
        v_Sql := 'INSERT INTO ' || p_AudTableName || '(HIST_DTTM, ' || v_ColNames || ' )'
                  || ' SELECT systimestamp, ' || v_ColNames || ' FROM ' || p_TableName
                  || ' WHEN ROWID = chartorowid(' || CHR(39) || p_RowId || CHR(39) || ')';
         EXECUTE IMMEDIATE v_Sql;

After Insert Trigger - IF-THEN-ELSE

Is it possible to put an if-then-else statement in an after insert trigger with an update to a second table?
CREATE OR REPLACE trigger bev_trg
after insert
on bev
for each row
DECLARE
MEINS VARCHAR2(3);
SPART VARCHAR2(2);
FKIMG NUMBER(22);
SHKZG CHAR(1);
BEGIN
insert into bev2
(vbeln,
posnr)
values
(:new.vbeln,
:new.posnr
IF FKIMG = '10' and MEINS = 'EA'
THEN
     update bev2 set bwsie = (fkimg * '12.17') ;
ELSIF
FKIMG = '12' and MEINS = 'EA'
THEN
     update bev2 set bwsie = (fkimg * '19.02');
ELSIF
SHKZG = 'X'
THEN
     update bev2 set bwsie = (fkimg * '-1');
ELSE
     update bev2 set bwsie = '0' ;
END IF;
update bev2 set bwfkimg = (fkimg * '-1') where SHKZG = 'X';
end;
This does not do the updates.
Thanks
Bev

My original problem is this: I need to create a table
derived from data in another table
and change it to be the conditional data in the update statements.
create table bev(
VBELN VARCHAR2(10),
POSNR VARCHAR2(6),
MEINS VARCHAR2(3),
SPART VARCHAR2(2),
FKIMG NUMBER(22),
SHKZG CHAR(1),
BWSIE NUMBER(9,2),
BWFKIMG NUMBER(22)
update bev set bwsie = (fkimg * '12.17') where SPART = '10' and meins = 'EA' ;
update bev set bwsie = (fkimg * '19.02') where SPART = '12' and meins = 'EA';
update bev set bwsie = (fkimg * '27.39') where SPART = '15' and meins = 'EA';
update bev set bwsie = (fkimg * '48.69') where SPART = '20' and meins = 'EA';
update bev set bwsie = (fkimg * '109.56') where SPART = '30' and meins = 'EA';
update bev set bwsie = '0' where meins = 'EA' and SPART not in('10','12','15','20','30');
update bev set bwsie = (fkimg * '-1') where SHKZG = 'X';
update bev set bwfkimg = (fkimg * '-1') where SHKZG = 'X';
This did not produce the required results so I thought I would try
creating a second table
and using a trigger with if-then-else to update it.
Can't use the trigger on the
original table because it mutates.
create table bev2(
VBELN VARCHAR2(10),
POSNR VARCHAR2(6),
BWSIE NUMBER(9,2),
BWFKIMG NUMBER(22)

insert into bev select vbeln, posnr, meins, spart, fkimg , shkzg, '', ''

Hi to all,
In a table I have a field id that must be valorized from sequence.
It is possible valorize this sequence after the insert ?
I have tried to create a trigger like this:

How can resolve this problem ?
Thank You for help.

New trigger variables can only be changed in before row insert or update triggers.
Action
Change the trigger type or remove the variable reference.

Can't able to use :NEW in after insert trigger

When i am trying to assign value to an element of the NEW pseudo record, its giving error like :new pseudo record can't be used in this type of trigger.
What exactly i've done is given below
create or replace triger tri_name
after insert
on tab_name
for each row
begin
if :new.x='123' then
:new.y:=null;
end if;
end tri_name;
Thanks & Regards

from oracle documentation...
Old and new values are available in both BEFORE and AFTER row triggers. A new column value can be assigned in a BEFORE row trigger, but not in an AFTER row trigger (because the triggering statement takes effect before an AFTER row trigger is fired). If a BEFORE row trigger changes the value of new.column, then an AFTER row trigger fired by the same statement sees the change assigned by the BEFORE row trigger.
for more details read the documentation
