• Table is the mutation of error in after the update trigger

  Hello
  
  In all of my table, I have columns EDITDATE and EDITUSER. So whenever a table is updated I need to update these two fields with the USER and SYSDATE. For this I use a BEFORE UPDATE trigger. This trigger is activated, but I get "ORA-04091: table %s.%s is changing, function of triggering/can not see" error every time I update the table. I used this method in SQL Server. I understand that Oracle doesn't have to be the same as SQL Server but I do not know there is a way to do this. Do you know what it is?
  
  EDIT: Here is the Code of the trigger
  
  create or replace
  TR_LEGISLATION_CALCUL_AE RELAXATION
  BEFORE THE UPDATE
  ON LEGISLATION_CALCUL
  FOR EACH LINE
  DECLARE
  v_LEGISLATIONCALCULID NUMBER (10,0);
  
  BEGIN
  SELECT: NEW. LEGISLATIONCALCULID
  
  IN v_LEGISLATIONCALCULID
  FROM DUAL;
  UPDATE LEGISLATION_CALCUL
  SET EDITUSER_ID = UID,
  EDITDATE = SYSDATE
  WHERE LEGISLATIONCALCULID = v_LEGISLATIONCALCULID;
  END;

  just put this in your before update (and not after the update as you mentioned) for each trigger line:

  BEGIN
  
  :new.EDITUSER_ID := UID;
  :new.EDITDATE := SYSDATE;
  
  END;
  

• After the update trigger

  I'm updating of certain rows in a table from front end applications...
  
  If I update a particular Null line... then the other value in the column is to replace assets
  
  Can I write an update trigger after for this
  
  Can we use if like else statements in triggers
  
  If a is null, then b is active
  

• After that insert update trigger does not work properly

  Hello experts!
  
  I created an insert/update trigger after and what strikes me is that it does not work as expected.
  The trigger starts a procedure that performs an insert in a second case of changing values table triggered table ("my_table").
  
  The problem is that in my second table values, which are correlated to the "my_table", are not changed by the correct values immediately. The trails of the trigger and insert!
  
  I need to update two times to values appear in my second table. Then only the data of the first update will be inserted in the second recital to table the table parent ("my_table") held the most recent values.
  
  Do you have an idea what could be the problem?

  Remove the pragma autonomous_transaction and validation of your relaxation. This might be the reason. The transaction autonoumous cant properly consider the values of the current transaction (which is not engaged yet).

  This is not logically (if the upgrade fails or is rolled at the time you do not want the inserted row).

  If you then get a problem because the mutation of tables, you will need a different solution: an autonoumous transaction is not the right solution to workaround.

• help find out what is wrong w / my before update trigger

  Let me this prefix w / the fact that I am a fool, so be nice.
  
  I have a trigger that does not (apparently), and I'll google out so I thought I would ask and see if someone could not provide thoughts, insults, suggestions or what have you.
  
  Database used is 10g XE and updates are performed in a transactional way.
  
  I have a table that contains (among other things) the status of a particular type of transaction (specific application). When this status changes to a particular value, I have a trigger that updates another table with the date on which that status change took place.
  
  < pre > Table: XTransaction
  ID (pk)
  StatusID (integer)
  ... < / pre >
  
  and here is my trigger:
  
  < pre > create or replace trigger x_transaction_update before update on xtransaction
  for each line
  declare
  Start
  If (: old.statusid = 1) then - it's here because I got an error when I tried to use a when clause above
  Start
  -I log in before the update with some other info to tell whether or not I've been to this task
  Update sometable set when_it_happened = sysdate where xtransid =: old.id;
  -I log in after the update too
  exception
  while others then
  -I connect sqlerrm
  end;
  end;
  end if;
  end; < / pre >
  
  
  Here's what I could gather through tests and display the logs of the trigger:
  
  1. There is no exception being connected,
  2. the update of pre/post connects with all the correct data (to prove that the trigger is activated),
  3. when I update xtransaction for visual studio (via the oracle complement that allows to execute queries against the database), the State is changed, the trigger is activated and the other table is updated.
  4. when running the application that normally updates the xtransaction table, xtransaction is updated, the trigger is activated and sometable is not updated.
  
  
  
  So I have absolutely no idea where to go with this one. Usually I could launch sql server Query Analyzer and watch what comes through, and I tried commercial tool use Toad to do this, but nothing is. I tried to change to an update after, but had the same results. I wrote this a few months ago and it worked then, but not now.

  Thanks a lot for the display of the actual error.

  Are you trying to work around the famous error table mutation here?
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:8323596621929

  You should use the transaction autonomous only for error logging procedure.
  You use a registration for different purposes.
  You are being "independent" on totally different levels.
  Creating a "while OTHERS" - registration procedure (being an autonomous transaction), or remove WHEN E.A.
  (or: delete the other calls to your logging procedure).
  This is a right step: get rid of the "distractions" and keep your code clean/crisp and clear as possible.

• Help update trigger

• UPDATE trigger

  Hi all

  I would like to help if this triggers, as I don't know if I did it correctly. But I don't think I have.

  create or replace TRIGGER update_ExpiryDate

  END;
  

  Let me explain what I want the trigger to do. I want to update a column called renewal, if the license has expired. I'm not sure if I'm missing something but its not working do not at all / can you please help?

  Thank you

  Well, I want to do is update the renewal date for "1 July 2017 ' if the lower expiry date 1 June 15 > that's what I'm trying to do.

  Thank you

  So why not do as others have already suggested. Govern this value in your original trigger (without update part) for all new lines if you wish.

  When: new.expirydate< date="" '2015-06-01'="" then="" :new.renewal="" :="date">

  If the old lines need fixing, and then with a single update statement.

  update drivers set = renewal date ' 01-07-2017' where had< date="">

  
  

  After that, you should have no record of drivers with dates of renewal except July 1, 2017 when displayed<>
  

• UPDATE to update trigger another table

  I am trying to write a trigger to the table (AFTER UPDATE) in which I want to update the same table in a different pattern. Notice that both tables has no unique or primary key constraint, so I am forced to compare the values in the column all the to the place where the condition.

  Update OTHERSCHEMA. T1

  the value =:NEW.c1 c1, c2 is:NEW.c2...

  where c1 =:OLD.c1

  AND c2 =:OLD.c2

  Problem is when a column is null, it would seem that it is not comparable. I even tried

  Update OTHERSCHEMA. T1

  the value =:NEW.c1 c1, c2 is:NEW.c2...

  where NVL (c1, NULL) = NVL (:OLD.c1, NULL)

  AND NVL (c2, NULL = NVL (:OLD.c2, NULL)

  Nothing helps. Can someone help me to write the correct statement?

  Nothing helps.

  Naturally.  NVL (x, NULL) is always x, no matter what x is.

  Can someone help me to write the correct statement?

  x = is returns TRUE if (and only if) x and have the same value, and it returns FALSE if (and only if) x and have 2 different values.

  NULL is not a value; in fact, it's quite the opposite.  NULL means that there is no value.  If x or is NULL, then x = y returns UNKNOWN.

  DECODE allows to compare values or NULL values, so you can do something like

  Update OTHERSCHEMA. T1

  the value of c1 =: NEW.c1

  , c2 =: NEW.c2

  ,       ...

  where LESS (DECODE (c1,:OLD.c1, 1, 0)

  , DECODE (c2,:OLD.c2, 1, 0)

  )

  ;

  If you would care to a full test script so that I can reproduce the problem, then I could test this.

  Triggers often indicate a bad table design.  Why do you need to replicate the data in another table?

  As you do, why not add a primary key?

  Do you see an UPDATE statement in the code example I provided?

  Have you tried the code I provided?

  The trigger is already PART of a statement to upate. When the trigger is activated, you are ALREADY updated in the table.

• BEFORE the UPDATE trigger between field in both tables

  Hi Oracle Experts,

  I'm a newbie in the triggers. I want to do a trigger that fires whenever changes are made to a table, updates a field in the second table. The details are as below:

   SAMPLE (
  SAMPLEID    NUMBER(10,0)
  ACTIVITYID     NUMBER(10,0)
  ACTIVITYTABLEID     VARCHAR2(20 BYTE)
  SAMPLEDT     DATE
  SAMPLEPTID     VARCHAR2(20 BYTE)
  SAMPLENOTIFY     VARCHAR(1 BYTE)
  )
  

  SAMPLE_RESULT(
  SAMPLEID     NUMBER(10,0)
  TESTID     VARCHAR2(20 BYTE)
  PROPERTYID     VARCHAR2(20 BYTE)
  TESTERID     VARCHAR2(20 BYTE)
  ENTRYDT     DATE
  RESULTNUM     NUMBER(18,8)
  RESULT     VARCHAR2(20 BYTE)
  RESULTTYPE     VARCHAR(1 BYTE)
  RESULTSTATUS     VARCHAR2(1 BYTE)
  )
  

  The idea of relaxation:

  CREATE OR REPLACE
  TRIGGER "DBA".AUTO_NOTIFY
  BEFORE UPDATE OF RESULT ON SAMPLE_RESULT
  FOR EACH ROW
  WHEN (NEW.PROPERTYID = 'Action Taken')
  BEGIN
  
  //my idea
  :new.sample.samplenotify = 'S'
  
  //but i don't know how to make a reference to another table
  
  END;
  

  The trigger will fire every time the propertyid is pronounced, it sets the value of samplenotify in the example in table for the of '.

  Is this possible?

  Thank you in advance.

  La: new.column_name syntax applies only to the table that the trigger is on.  You will need to use an update on the other table.

  CREATE OR REPLACE TRIGGER auto_notify

  BEFORE the UPDATE result WE sample_result

  FOR EACH LINE

  WHEN (NEW. PROPERTYID = "Taken Action")

  BEGIN

  Example of UPDATE

  SET s = samplenotify"

  WHERE sampleid =: NEW.sampleid;

• Multicolumn update trigger

  Hello
  
  I want to have a track history of any data that has already been updated in a table. Say that table1 has 100 columns and to store historical data on change, I did another table track_table1 with columns: updated_column_name, old_data, you see, mod_time.
  
  For this history of data storage, I need to write a trigger in which I will identify all columns whose value update and insert the name and column values in the track_table1 table.
  
  What I'm doing now is to check each of the 100 new and old value column inside the trigger to know what columns have been updated. This increases the code and oracle must also check the values of each column 100 to find out if it is updated.
  
  Is there a way where oracle itself can give a list of columns that have values updated by the update? While there is no need to check the values old and new in each column of the table.
  
  I am using oracle 9i and 10 g databases.

• BackingMap updates trigger EventListeners

  3.7 consistency, since in an EntryProcessor update another entry via map of support directly (on a partition level operation). This update will trigger the dumps and BackingMapListeners respectively for the other entry?
  
  I have a dumps that persists changes asynchronously, so wonder if direct changes to the map of support will be also persisted
  
  Thank you

  Hi David,

  Yes, the CacheStores and the BackingMapListeners fires with direct updates to a storage card.

  Although you have not asked about them, MapTriggers may or may not be fired depending on how the support plan is updated. If you get real support plan and do an update then the trigger does not fire unless you use the new 3.7 path of update of media by obtaining the entry of a key of the BackingMapContext and the appellant setValue during entry then the trigger fires.
