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 ... is mutating, trigger/function may not see it

    Hi,
    I keep getting this error message for my trigger when performing an
    insert..select statement (standard plain old insert works):
    ORA-04091: table ... is mutating, trigger/function may not see it
    The trigger is as follows:
    CREATE OR REPLACE TRIGGER MYTABLE_BEF_INS_CHECK
    BEFORE INSERT ON MYTABLE
    DECLARE
    v_o_id number(10);
    BEGIN
    IF :new.TYP = 'O' THEN
    SELECT 1
         INTO v_o_id
         FROM MYTABLE WHERE TYP = 'O' AND ID=:new.ID;
    END IF;
    END;
    The thing is the trigger works fine for a standard insert like:
    insert into MYTABLE( id,typ)
    values(426672,'O')
    No problem the above works. But when I try an insert select..it
    fails.
    insert into MYTABLE( id,typ)
    SELECT x_id, 'O' from AnyOtherTable;
    the above will fail.
    Anyone an idea why this is the case??
    thx.

    Hi,
    OK OK !!!! This was a copy/paste error. FOR EACH ROW was just not pasted here. Full trigger again:
    CREATE OR REPLACE TRIGGER MYTABLE_BEF_INS_CHECK
    BEFORE INSERT ON MYTABLE
    for each row
    DECLARE
    v_o_id number(10);
    BEGIN
    IF :new.TYP = 'O' THEN
    SELECT 1
         INTO v_o_id
         FROM MYTABLE WHERE TYP = 'O' AND ID=:new.ID;
    END IF;
    END;
    But I want to know why I DO NOT get this problem with the standard insert statement but only with the insert...select.
    thx.

  • ORA-04091: table CCS.T_PROCESSLOG is mutating, trigger/function may not see it

    I have a problem. Here is a trigger that I'm working with.
    CREATE OR REPLACE TRIGGER Trgedw_extract
    AFTER INSERT OR UPDATE OF completioncode ON CCS.t_processlog
    FOR EACH ROW
    WHEN ( (OLD.filename = 'ACCTINFO') AND (OLD.completioncode = 1) )
    BEGIN
    CCS.Edwextract;
    END;The t_processlog table has a field (processid) that is the primary key. However the processid wasn't setup as a sequence number directly through Oracle. It was set up as a sequence number through a trigger. (Don't ask...)
    The code for the procedure that the code above call is here.

    /I guess my confusion is how can I put a trigger on the t_processlog table to start a job when another finishes, and still have the job called make an entry into the t_processlog? I looked at the code for suggested work around, but I'm a little confused as to what is going on. Can anyone give me an idea for what to do in the situation? Thanks.

    I didn't see your coding but i think you are selecting the same table through the procedure, on which you have written the db trigger.
    In that case it will alway gives you mutating error.

    What I wrong in this trigger??

  • 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: 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?

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

    Hello All,
    I am not an expert in oracle and I have been facing a problem where I get a message as follows :
    ORA-04091: table <table> is mutating, trigger/function may not see it
    I have a table tab1 which has ID, name, and some other columns. the rows in this table form a parent-child type relationship based on some columns within that table. I have created another table called relationship table. The relationship table has 2 columns ID and parentID. I keep this table up to date using triggers. For example if a new record is inserted or upadted in tab1 which affects the parent - child relationship, i update the relationship table accordingly using an insert / update trigger and it works fine.
    I created another trigger as follows
    create or replace trigger MY_DELETE_TRIGGER
    after delete on tab1
    for each row
    BEGIN
    update relationships a set a.parentID = null where a.parentID = :OLD.ID;
    delete from relationships a where a.id = :OLD.ID;
    END MY_DELETE_TRIGGER;
    Basically what I am doing is, the record once deleted, if it was parent of anybody else, i am setting the parent as null and the record itself, if it was in the relationships as a child, I am removing that row.
    This is when I get the table is mutating error, and I don't know how to fix it.
    Can anybody please help me,
    Thanks in advance

    Could you provide more details?

  • Table is mutating, trigger/function may not see it

    Hi,
    I have been trying to get a trigger to execute a stored procedure when an update is made to a row in a table.
    The procedure works when ran manually and the trigger compiles but when the trigger is fired I get a "table is mutating, trigger/function may not see it" error.
    Here's a bit more background:
    I have a product table where the cost of a product is calculate based on costs in other tables (e.g. cost of raw materials is in the suppliesrawmat table).
    I have written a procedure (called proc_costcalc) which takes in a productID and updates that product's cost in the product table.
    I want a trigger to do this for every affected product when a rawmaterial cost is changed.
    The code of my trigger is:
    CREATE OR REPLACE trigger trig_rawcostupdate
    AFTER INSERT OR UPDATE ON suppliesrawmat FOR EACH ROW
    DECLARE
         cursor c1 is
         SELECT p.prodid
         FROM process p,
              (SELECT s.processid
              FROM stage s,
                   (SELECT stageno
                   FROM stagerawmat
                   WHERE prodid = :new.prodid) subquery0
              WHERE s.stageno = subquery0.stageno) subquery1
         WHERE p.processid = subquery1.processid;
    BEGIN
         FOR tuple in c1
         LOOP
              proc_costcalc(tuple.prodid);
         END LOOP;
    END;
    The query for the cursor generates a list of productIDs which I need to run through the proc_costcalc procedure.
    Can anyone show me where I am going wrong? How can I fix this?
    Thanks
    Keith

    I'm afraid I'm still not getting this.
    Suppose I have 4 tables (product, madefrom, rawmat and suppliesrawmat).
    Product (productid, cost)
    Madefrom (productid, rawmatid)
    Rawmat (rawmatid)
    Suppliesrawmat (supplierid, rawmatid, cost)
    The cost of a product should be the sum cost of all rawmaterials it is made from where the cheapest supply cost of that material is used.
    What I want to do is update the cost of a product when the cost of a raw material used in its production changes.
    My earlier attempt was to have a procedure which when given a productid updates the price of that product. However, when trying to call this procedure from an update on the suppliesrawmat table I recieved the table is mutating error. I now understand why (thanks to everyone for that) but I still don't really know how to rectify the problem.
    How should I be doing this?
    Thanks again
    Keith

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

    First off, there are NO TRIGGERS defined on the table in question in our database.
    The process we need to accomplish is as follows:
    1.  Load addresses from the table.
    2.  Send the addresses through a standardization routine.
    3.  Multi-Insert any address that was successfully standardized and is not already present.
    So how do I tell ODI 12c to create a temporary table before doing the multi-insert?  So far everything I've tried gets "flattened" and results in the same error.
    OR
    Is there a different solution?
    Thanks for your help,
    Scott

    I fixed this by creating a second Physical+Logical+Model to the same database (not sure if I needed all three but did it this way to make sure).  This caused ODI to generate a SOURCE_GROUP and TARGET_GROUP instead of just a TARGET_GROUP in the physical view.  Then all I had to do is on the properties of the first item in the target, set the properties on the LKM Oracle to Oracle Pull (DB Link).GLOBAL to whichever option I wanted (USE_STAGE_TABLE or SELECT_FROM_SOURCE_VIEW).  One thing to do is put the database's own SID in the SOURCE_ACCESS_DB_LINK so it doesn't create an unnecessary DB Link.
    Hope that helps someone else!

    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.
