hi
while executing this:
SQL> insert into LIB_ACCESSION_LOG select * from LIB_ACCESSION_LOG11;
insert into LIB_ACCESSION_LOG select * from LIB_ACCESSION_LOG11
ERROR at line 1:
ORA-04091: table QA.LIB_ACCESSION_LOG is mutating, trigger/function may not
see it
ORA-06512: at "QA.TRG_ACCESSION_LOG", line 2
ORA-04088: error during execution of trigger 'QA.TRG_ACCESSION_LOG'
how can i do this insert and resolve this error. should i switch off the constraints? and what will happen when i switch on the constraints?

Check the trigger code for QA.TRG_ACCESSION_LOG.
Read here as to how the mutating error can be eliminated.

ORA-04091:table XYZ is mutating,trigger/function may not see it ORA-06512

Hi everybody
i am facing mutating problem during data deletion fron XYZ table as
ORA-04091:table XYZ is mutating,trigger/function may not see it ORA-06512 at "user.procdure_name",line 39 ORA-065
i have table XYZ and have database trigger on this table
and also have procedure "user.abc" in this procedure m selecting data from xyz table

You didn't post the actual code. I was more interested in seeing table name and the trigger body.
Anyways, mutation problem comes when you refer the same table on the trigger, on which it is based for some data manipulation on that table.
For e.g, If inside your trigger body, you are doing INSERT on the same table, then it'll definitely result in mutation problem because this trigger will be fired endlessly (as it is after insert trigger).
Please mark answer as helpful / correct, if it helps you

ORA-04091: is mutating, trigger/function may not see

                      I got data when I ran just the select statement, none of the records have data in the sarquan table.
I got data when I select from this function

Any ideas?

I can not drop the trigger, I don't own the trigger, it is in production, SARQUAN is a production table
Now I am getting this error ORA-04091: table SATURN.SARQUAN is mutating, trigger/function may not see it

the sequence go by pidm

How to get around ora-ORA-04091: table SSBOSS.SSTRMAST is mutating, trigger

hi,
Does anyone know how one would get around this problem please ?
Here is my dbase trig:
CREATE OR REPLACE TRIGGER SSBOSS.new_not_greater_than_net
BEFORE INSERT OR UPDATE OF newrent ON SSBOSS.SSTRMAST
REFERENCING NEW AS new OLD AS old
FOR each row
DECLARE
not_permitted EXCEPTION;
vnum number := ssboss.nik_f;
BEGIN
IF :new.NEWRENT > vnum then
--AND :old.DELETED = 'N' THEN
RAISE not_permitted;
END IF;
EXCEPTION
WHEN not_permitted THEN
RAISE_APPLICATION_ERROR
(-20001, 'NEWRENT:'||:new.newrent||' '||'OLDRENT:'||' '||:old.netrent||'Action not permitted. Contribution (sstrmast.newrent) value '
||:new.NEWRENT
||' exceeds GROSS rental value (sstrmast.netrent) ');
END;
Here is my problem:
SQL> update sstrmast set newrent = 11;
update sstrmast set newrent = 11
ERROR at line 1:
ORA-04091: table SSBOSS.SSTRMAST is mutating, trigger/function may not see it

ORA-06512: at "SSBOSS.NEW_NOT_GREATER_THAN_NET", line 4
ORA-04088: error during execution of trigger 'SSBOSS.NEW_NOT_GREATER_THAN_NET'
I understand why but not how to correct?
Thanks,
nikolia.

Hello,
This problem as you might be knowing occurs when you try to select the data from the same table on which the trigger is written. Also this problem is only with the row level trigger and not with the statement level trigger. However the limitation of the statement level trigger is it can not refer to :NEW or :OLD. So now the solution is to capture the value of :NEW or :OLD in the row level trigger (no select statement here) and store it in some global variable. And how do you get the global variable? Using package specification ! a variable declared in a package specification is global in nature. Then use the value so stored in the statement level trigger in the select statement. It will work. Other solution is to use pragma autonomous transaction. Try and let us know. All the best.

Yes, and I'm reading this on a computer screen!
What functional requirement are you trying to achieve?
And have you googled? If so, you would have found this

What I wrong in this trigger??
How can I modify it??

thanx!!!! :-)

Tad,
I believe you're performing SELECT on the triggering table in the PL/SQL block. In simple words, you're trying to change the information of a table the TRIGGER is created for and you're trying to read data from the same table.
I suggest that you use PL/SQL pragma autonomous_transaction to resolve this, for as per Oracle documentation "The AUTONOMOUS_TRANSACTION pragma instructs the PL/SQL compiler to mark a routine as autonomous (independent). An autonomous transaction is an independent transaction started by another transaction, the main transaction. Autonomous transactions let you suspend the main transaction, do SQL operations, commit or roll back those operations, then resume the main transaction."
Furthermore, you can also refer to the following discussion by Thomas Kyte for further understanding of mutating tables:
Avoiding Mutating Tables

Hope this helps.

Naveed.

How to solve ORA-04091

hi,
i made a trigger on a table fire on after insertion but i m having these error so plz try to solve it.

ORA-04091: table master is mutating, trigger/function may

ORA-06512: at "TG1", line 5
ORA-04088: error during execution of trigger 'TG1'

You don't understand mutating tables and how to avoid them. Nor do you understand how multi-user systems work. Finally you appear not to understand how to use the documentation Given all that, your soubriquet is overambitious. You might want to consider a more modest handle.
As for the specifics, how to avoid the ORA-4091 error, the root cause is that we cannot select on the table in question in a FOR EACH ROW trigger. You seem to be after an incremental count, presumably as unique identifier. This is the wrong approach: use a sequence and stop worrying about gaps.

Trigger to copy records from one table to another; ORA-04091:

Hello,
I'm trying to create a trigger that will move data from one table to another.
I have two tables (Trial1, Trial2) Both of them contains the same attributes (code, c_index)
I want to move each new record inserted in (code in Trial1) to (code in Trial2)
This is my trigger:
Create or replace trigger trg_move_to_trial2
After insert on Trial1
for each row
begin
insert into Trial2 (code)
select :new.code from Trial1;
end;It compiled, but when I insert new (code) record into (Trial1) it display this error:
Error report:
SQL Error: ORA-04091: table STU101.TRIAL1 is mutating, trigger/function may not see it
ORA-06512: at "STU101.TRG_MOVE_TO_TRIAL2", line 3
ORA-04088: error during execution of trigger 'STU101.TRG_MOVE_TO_TRIAL2'
04091. 00000 - "table %s.%s 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.I know what does this error mean, but I don't how to fix the error.
I tried to change the (After insert on Trial1) to be (Before insert on Trial1); that worked, but not in the right way. When I insert new value into (code in Trial1) and refreshed Trial2 table, as much as records I have in Trial 2 they will be duplicated. E.g.
Trial2
code
111
222
333when I insert in Trial1
Trial1
code
444
Trial2 will be:
code
111
222
333
444
444
444Can you please tell me how to solve this issue?
Regards,
Edited by: 1002059 on Apr 23, 2013 5:36 PM

You should not select from Trial1 - you have the data already. Just insert that value.
Create or replace trigger trg_move_to_trial2
After insert on Trial1
for each row
begin
insert into Trial2 (code)
values (:new.code);
end; regards,
David

Thanks i have read it and used the Before Insert Trigger i got ride of the problem but with now results
i need 2 read it in depth but time is limited 2 the task,1 friend once told me 2 use a twin table as a transite 2 manipulate the functionality of my bussiness
i did and it worked fine but i was just wanted 2 know other experienced people they offered many worked solutions but they didn't agree with each other.
So u know...
am little confused which best solution 2 use so i posted as an Ora not the name of the Ora
hope someone help or suggest a help.

Sending email ORA-04091

I am trying to follow the example in Oracle HTML DB User's guide to send an e-mail to a just entered email address.
The trigger seems to compile and be valid but when I enter a record I get:
ORA-04091: table FOLKLORE.SERVICEREQUESTS is mutating, trigger/function may not see it ORA-06512: at "FOLKLORE.SERVICEREQUESTS_T1", line 3 ORA-04088: error during execution of trigger 'FOLKLORE.SERVICEREQUESTS_T1'
My trigger looks like:
Schema FOLKLORE
Trigger Name SERVICEREQUESTS_T1
Trigger Type AFTER EACH ROW
Triggering Event INSERT
Table Schema FOLKLORE
Base Object Type TABLE
Table Name SERVICEREQUESTS
Column Name (null)
Referencing Names REFERENCING NEW AS NEW OLD AS OLD
When Clause (null)
Status ENABLED
Description "SERVICEREQUESTS_T1" AFTER insert on "SERVICEREQUESTS" for each row
Action Type PL/SQL
Trigger Body
begin
if (inserting and :new.srid is not null) then
for c1 in
(SELECT REQUESTOREMAIL FROM SERVICEREQUESTS WHERE SRID = :new.srid)
loop
if c1.REQUESTOREMAIL is not null then
     htmldb_mail.send(
     p_to => c1.REQUESTOREMAIL,
     p_from => c1.REQUESTOREMAIL,
     p_body => 'Your service request has been submitted for review',
     p_subj => 'Service Request');
end if;
end loop;
end if;
end;
And the table looks like:
SQL> desc servicerequests;
Name Null? Type
SRID NOT NULL NUMBER(5)
DATEOFREQUEST NOT NULL DATE
DATENEEDED DATE
REQUESTOR NOT NULL VARCHAR2(40)
REQUESTOREMAIL NOT NULL VARCHAR2(50)
REQUESTORPHONE NOT NULL VARCHAR2(4)
REQUESTORPROGRAM NOT NULL VARCHAR2(50)
PROJECTTITLE NOT NULL VARCHAR2(50)
PROJSCOPE NOT NULL CLOB
PRJJUSTIFICATION NOT NULL VARCHAR2(3000)
ESTCOST NUMBER(5,2)
BUDGETED CHAR(1)
FUNDSOURCE VARCHAR2(50)
DEVID NOT NULL NUMBER(2)
DEVOTHER VARCHAR2(50)
NUMBEROFUSERS NUMBER(3)
CREATEDATE NOT NULL DATE
STATUS NOT NULL VARCHAR2(20)
STATUSDATE NOT NULL DATE

It might be better to create a PL/SQL Package api to to this table. Let it handle the insert and the email. You could use "insert into ... returning id into l_id" to get back the pk from the insert and still be able to use it in your email. You also wouldn't have to worry about the mutating triggers issue.
Just a thought,
Tyler

SQL, PL/SQL functions, and ORA-04091 table is mutating

Dears,
Recently a question came up in an Oracle French forum about an insert/select that is throwing ORA-04091: table xxxx is mutating, trigger/function may not see it error in 11g while the same insert/select was working very well in 10g. The original poster gave a scenario that is easily reproducible. I am wondering what database release is correct the one throwing the error(11g) or the other one accepting the insert/select(10g)?

ohamed@mhouri> drop table tr_read_consistency;
Table dropped.
mohamed@mhouri> create table tr_read_consistency

3              select rownum, id,vc
4           from table(f_read_consistency_tab);
10 rows created.So is this a regression? or a corrected bug during upgrade?
Thanks in advance

SQL>So, you have to add only PRAGMA AUTONOMOUS_TRANSACTION; before begin in your function code to avoid ORA-04091 in 11.2.0.1
But, All thanks to Tubby who pointed us to the correct documentation link.
