ORA-06512 - Mutating trigger

Here is the code:
CREATE OR REPLACE TRIGGER FPMENU00_update
AFTER UPDATE ON FPMENU00
REFERENCING OLD AS old
NEW AS new
FOR EACH ROW
BEGIN
UPDATE FPSMNU00
SET Menu_Name = :new.Menu_Name
WHERE Menu_Name = :old.Menu_Name;
END;
When I attempt to update the table FPMENU00, I am getting the error message:
(table fps.fpmenu00 is mutating, trigger/function may not see it ORA-06512: at "FPS.FPMENU00_UPDATE", line 2 ORA-04088: error during execution of trigger fps.fpmenu_update)
The Menu_Name also has a foreign key constraint on the FPSMNU00 table.
Is this not possible????
Thanks

A MUTATING TRIGGER is a case when you are updating a table, and the trigger fires. AND within that trigger itself you are firing another update to the same table. Oracle cannot handle that because it will create an infinite recursion of updates.
From your trigger body I see that
UPDATE FPSMNU00
SET Menu_Name = :new.Menu_Name
WHERE Menu_Name = :old.Menu_Name;
WHY ARE YOU DOING THAT?
Is it because any update to any column in that table should update the Menu_Name column? In any case the assignment Menu_Name = :new.Menu_Name is NOT REQUIRED. That is going to take place by itself.
Could you explain your scenario more.

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

                      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?

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

vnum number := ssboss.nik_f;
BEGIN
IF :new.NEWRENT > vnum then

RAISE not_permitted;
END IF;
EXCEPTION

END;
Here is my problem:

I understand why but not how to correct?
Thanks,

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.

ORA-04091 table string.string is mutating, trigger/function may not see it

When I am tending to delete something from my table I received this message.
I defined a PL/SQL function reads data from that table. Is that meaning I could not modify anything in table once I have some PL/SQL defined on that? It sounds ridiculour. Or I missed some points?
Anyone could help me out?
Many thanks,
Qiang

In get_point_coordinates(point_id, layerid), it does not have any codes deleting thing from point_tab.
Its functionality is to find out that specified point;
put its coordinates into SDO_GEOMETRY object and return as function value.
However, oracle does not allow me to delete any data from point table since then.It is saying that function (get_point_coordinates) can not know mutating tables.
When I run delete task:
delete from point$_view where point_id = 1;
I got errors:
ERROR at line 1:
ORA-04091: table POINT$_TABLE is mutating, trigger/functio
n may not see it
ORA-06512: at "GET_POINT_COORDINATES", /* THIS LINE REPORS ERROR*/ Look at codes below.
The following is code of function: GET_POINT_COORDINATES
FUNCTION GET_POINT_COORDINATES(pPoint_ID IN NUMBER, player_ID IN NUMBER)
RETURN MDSYS.SDO_GEOMETRY DETERMINISTIC IS
PSRID NUMBER :=NULL:
PLON NUMBER := NULL;
PLAT NUMBER := NULL;
CURSOR get_lonlat(ppoint_id IN NUMBER, player_id IN NUMBER) IS SELECT LON,LAT
FROM POINT$_VIEW /* THIS LINE REPORS ERROR*/
WHERE player_id = layer_id AND ppoint_id = point_id;
BEGIN
PSRID := 8265;
OPEN get_lonlat(pPoint_ID,Player_ID);
FETCH get_lonlat INTO PLON, PLAT;
RETURN MDSYS.SDO_GEOMETRY(2001,PSRID,MDSYS.SDO_POINT_TYPE(PLON,PLAT,NULL),NULL ,NULL);
END GET_POINT_GEOM;
I guess it has nothing with foreign key. There is something wrong with this function.
By the way, a spatail index is built on this function. Does this make any differences on this point?

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

I create this trigger:
CREATE OR REPLACE TRIGGER pr_test
after insert ON AM
FOR EACH ROW
declare
appo_pr varchar2(64):= null;
BEGIN
select name
into appo_pr
from AS
where AS_ID=:new.AS_ID;
insert into AM (name) values (appo_pr);
END pr_test;
I insert before a new AS_ID and name in tab AS but when I insert a new record in tab AM I get this error:
ORA-04091: table AM is mutating, trigger/function may not see it
ORA-06512: at PR_TEST", line 11
ORA-04088: error during execution of trigger PR_TEST'
I'd like to create a trigger that when I insert a new record in AM It verify the value in col name of AS and insert this value in col name of AM.
What I wrong in this trigger??
How can I modify it??
Thanks
Raf

Try this:
CREATE OR REPLACE TRIGGER pr_test
before insert ON AM
FOR EACH ROW
declare
appo_pr AS.name%TYPE;
BEGIN
select name
into appo_pr
from AS
where AS_ID = :new.AS_ID;
:new.name = appo_pr;
END pr_test;

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:

Hope this helps.

And do you have a trigger on the GROUP_LIST table that calls you function that queries the GROUP_LIST table?
The solution is simple: DON'T DO THAT!
See Trigger Restrictions on Mutating Tables in the SQL Language doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/triggers.htm#g1699708
Trigger Restrictions on Mutating Tables
A mutating table is a table that is being modified by an UPDATE, DELETE, or INSERT statement, or a table that might be updated by the effects of a DELETE CASCADE constraint.
The session that issued the triggering statement cannot query or modify a mutating table. This restriction prevents a trigger from seeing an inconsistent set of data.
This restriction applies to all triggers that use the FOR EACH ROW clause. Views being modified in INSTEAD OF triggers are not considered mutating.
When a trigger encounters a mutating table, a run-time error occurs, the effects of the trigger body and triggering statement are rolled back, and control is returned to the user or application. (You can use compound triggers to avoid the mutating-table error. For more information, see Using Compound Triggers to Avoid Mutating-Table Error.)
Consider the following trigger:
CREATE OR REPLACE TRIGGER Emp_count

Whilst the table with the trigger on it is in the middle of a transaction you cannot select or use DML against it. This is what Oracle calls a "mutating table". It doesn't make sense to try and use a table that is in the middle of changing.
You can use an autonomous transaction to work around this issue, but you should be careful with autonomous transactions because there are drawbacks relating to maintaining transaction consistency. Effectively it means you will be making alterations to B based on the fact that A has happened, but the transaction on B will not get rolled back if A fails at any point which could leave you with A not complete but B complete, hence the inconsistency.

Rgding ORA-04091:table PURCHSE_DTL is mutating,trigger/function maynot c it

I wrote a trigger 'TRG_PURCHASE_DTL' to update the stock table 'BRANCH_ITEM_STOCK' based on the DML actions perfomed on tables PURCHASE_DTL and ISSUE_DTL, but I am getting following error:-
ORA-04091: table PURCHASE_DTL is mutating, trigger/function may not see it
and the value of 'BRANCH_ITEM_STOCK.purchase_qty' is updated to 10 instead of 18.
The table structure and data is given below:

ITEM_QTY NUMBER(6) null ,
RECEIPT_QTY NUMBER(6) null ,
constraint PK_RA25_ISSUE_DTL primary key (BRANCH_CODE, ISSUE_YR, ISSUE_NO, REC_SNO)
Assume that the Contents of PURCHASE_MST is as follows:
SELECT branch_code, purchase_yr, purchase_no FROM PURCHASE_HDR;
BRANCH_CODE PURCHASE_YR PURCHASE_NO
100          2008          1
100          2009          1
100          2009          2
Now I tried to insert follwing values to the PURCHASE_DTL table:
insert into purchase_dtl (BRANCH_CODE,PURCHASE_YR,PURCHASE_NO,rec_sno,
ITEM_CODE,item_QTY)
Values (100,2008,1,1,4,5)
insert into purchase_dtl (BRANCH_CODE,PURCHASE_YR,PURCHASE_NO,rec_sno,
ITEM_CODE,item_QTY)
Values (100,2009,1,1,4,2)
insert into purchase_dtl (BRANCH_CODE,PURCHASE_YR,PURCHASE_NO,rec_sno,
ITEM_CODE,item_QTY)
Values (100,2009,2,1,4,6)
commit
Now Contents of table ' PURCHASE_DTL ' is as follows:
BRANCH_CODE PURCHASE_YR PURCHASE_NO     REC_SNO ITEM_CODE     ITEM_QTY
100          2008          1     1          4     5
100          2009          1     1          4     2
100          2009          2     1          4     6
I want to write a trigger which will insert/update/delete data into/from BRANCH_ITEM_STOCK,
so that the contents of column Purchase_qty of table BRANCH_ITEM_STOCK should be as follows:
BRANCH_CODE     ITEM_CODE     PURCHASE_QTY     RECEIPT_QTY     ISSUE_QTY     BALANCE_QTY
100          4          13          0          0          13
[Note: i.e BRANCH_ITEM_STOCK.PURCHASE_QTY = SUM(PURCHASE_DTL.item_qty)
     where PURCHASE_DTL.branch_code=100
     AND PURCHASE_DTL.item_code=4
Now run the following update statement.
update purchase_dtl
set item_qty= 10
where BRANCH_code=100
and purchase_yr in ( 2008) and purchase_no =1 and rec_sno = 1 AND item_code = 4
commit
Now the actual contents of column Purchase_qty of table BRANCH_ITEM_STOCK should be updated as follows:
BRANCH_CODE     ITEM_CODE     PURCHASE_QTY     RECEIPT_QTY     ISSUE_QTY     BALANCE_QTY
100          4          18          0          0          18
But I am facing problem here. I am getting following error:-
ORA-04091: table PURCHASE_DTL is mutating, trigger/function may not see it
and the value of purchase qty is updated to 10 instead of 18
Similarly if any issue of items happen (for eg:- issue_qty=2 to branch_code 200), then the purchase_qty =18,issue_qty=2 , balance_qty:=18-2=16 .
So for branch_code 200 , receipt_qty = 2.
Pls help me how to achieve the above .

Thanks Jens Petersen for reply
now i want to make sure of one thing that i have to follow the steps but the last one i will replace it with my trigger NO?
SQL> create or replace package state_pkg
2 as
3 type ridArray is table of rowid index by binary_integer;
4
4 newRows ridArray;
5 empty ridArray;
6 end;
7 /
Package created.
SQL> create or replace trigger parent_bi
2 before insert or update on parent
3 begin
4 state_pkg.newRows := state_pkg.empty;
5 end;
6 /
Trigger created.
SQL> create or replace trigger parent_aifer
2 after insert or update of status on parent for each row
3 begin
4 state_pkg.newRows( state_pkg.newRows.count+1 ) := :new.rowid;
5 end;
6 /
Trigger created.
---------------------now come my trigger instead of the following one ??---------------
SQL> create or replace trigger parent_ai
2 after insert or update of status on parent
3 begin
4 for i in 1 .. state_pkg.newRows.count loop
5 insert into log_table
6 select theKey, status, effDate
7 from parent where rowid = state_pkg.newRows(i);
8 end loop;
9 end;
10 /
Trigger created.

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

Hi,
I have a row level before update trigger written on a table A which calls a procedure to undergo some processing. Procedure has some select queries against table A and it inturn causes the following error.
ORA-04091: table name is mutating, trigger/function may not see it
To overcome this I have used a combination of PL/SQL collection types (nested tables based on the following definition TYPE t_table_a is table of A.colname%TYPE index by binary_integer;), a row level before update trigger and statement level after update trigger. The mutating problem is fixed, but to update one row of data it took around 3 min and I am wondering if its the problem with PL/SQL tables I have used.
In before update trigger I am storing the unique id's which needs to be updated into the PL/SQL table and in the after update trigger I am looping through the PL/SQL table and peforming the rest of the processing by calling in the procedure.
Can anyone help how to minimize the run time of this process or if any other better solution exists?
Thanks for the help

Triggers raise the mutating table issue, because else they could be used to create endless loops. If you work around the mutating table issue, then you should make sure not to create an endless loop yourself. This would be possible.
You description also seems to imply something like this.
Without code it is impossible to say something specific.
- Do you initialize your collection in a before statement trigger?
- Is your looping mechanism somehow broken?
- Do you update the same table again and again and again?
