• How to create components of ADF BC as EO 'view with INSTEAD of trigger.

  I have a 'vision with INSTEAD OF trigger' on an external schema. is it possible to create the ADF EO on top of this point of view in my local schema?. If possible, then it is possible to insert/update this portal uses standard data ADF controls and module application.? I'm trying to see if it is possible with the standard controls of ADF without calling pl/sql API for insert/update this external table. any ideas are appreciated.

• Instead of trigger on a Materialized view?

  Hello
  
  We write INSTEAD OF trigger on the materialized view?

  When we refresh materialized, view view full is truncated and new records get inserted, it is on the books and we can do service work, but when the incremental refresh is done, this trigger will run I don't know.

  I'm not sure that I am. A complete refresh will cause insert triggers (line level and the table, before and after) fire for each row of the materialized view. An additional update will cause insert, update, and delete triggers (line level and the table, before and after) in the fire for each changed row. It may be of course, updates that do not actually change the data depending on how one defines the materialized view, and how changes should be handled.

• Using forms apex instead of insert trigger on view

  Hello
  
  I have a requirement where I have to have a form on two table and insert data in which the 1 table a PK that Fk one table.
  And I need to get the PK at apex so that I can browse additional after the insert/update successful.
  
  I tried methods.
  
  (1) used two table views to insert and then created instead of trigger to insert it.
  questions - work very well until I tried to use his return to apex app because return is not trigger INSTEAD of manage.
  
  (2) created a procedure to insert and then return PK at apex.
  Form questions - about the procedure does not allow to CHANGE.
  
  
  looking for expertise on this so that I can make insertion/update two different tables (in view) and get the value of the PK returned to the top.

  Hunk09,

  1. create a form on the view
  2. create a process manual plsql for condition: request = 'CREATE' using your function and save the PK of return in your article
  3. for condition: application (SAVE, DELETE') by default, use the process of automatic line

• instead of triggers - clarification

  Hi Experts,

  "Here's the quote from Oracle11g: PL/SQL approach" book in the INSTEAD of triggers

  "For all notice given, only ONE INSTEAD OF trigger can be defined for each of these OPERATIONS: Insert, update, delete..." Therefore, a view can have a maximum of three triggers INSTEAD of"

  A view can have a maximum of THREE triggers INSTEAD of? Is this true?

  Thanks in advance.

  Kind regards

  Richard

  In addition to Vivek and Frank:

  From a logical point of view and maintenance, it makes sense:

  There are 4 levels on which a trigger can pull:

  -before the declaration

  -before the line

  -After the row

  -After statement

  and 3 DML operations:

  -Insert

  -updated

  -Remove

  So, just do the math: 4 * 3 = 12

  but Oracle care not at all technically or physically how you create triggers, it also allows 3 or 12 triggers.

  In any case, read this article as well, you must use triggers when there is absolutely no other way to do what to do: ask Tom: The Trouble with triggers

• INSTEAD of triggers

  Hello
  
  anything can explain clearly the purpose of the INSTEAD of trigger... I'm confused, while I used that

  857773 wrote:
  in which case the view could not be updated become able?

  Fukunaga has demonstrated, but not really explained the reason for an INSTEAD OF trigger is to allow you to encode a manual process of updating a display base tables (or all the other tables you want) where the view is such that Oracle cannot determine how to upgrade the database tables itself.

  For a view to be updated, it must be able to identify the exact lines of the base tables that will will for example by making their internal rowid. In the example shown, a DISTINCT clause is used in the query, and will prevent the individual to be identified and thus prevent lines update work. There are other query constructs that also prevent views can be changed.

  Personally, I found very rarely need to try to update a view and then use the INSTEAD OF trigger. It is often easier to have the app just directly update the base tables.

• Trigger to prevent the update

  I want to create the trigger that will prevent illegal updates, but for illegal data, I want to insert into another table. In order to avoid the update, I have to make an exception, but it will insert is rollback. I am aware of the autonomous transactions (put I insert a procedure which is autonomous transactions) but it seems to me like dirty way to solve the problem. Y at - it another way to prevent the update that does not throw exception. I am also against the update on the same values. Thank you!

  FilipFry wrote:
  I checked the book, so now I am on the departure, how preventing the update in the after trigger without triggering an exception?

  The only way to prevent a updated row in a trigger would throw an exception.
  You may, of course, update leave unchanged data simply by setting the new value for each column in the old value, i.e.

  CREATE OR REPLACE TRIGGER some_trigger
    BEFORE UPDATE ON some_table
    FOR EACH ROW
  BEGIN
    IF( some_condition )
    THEN
      :new.column1 := :old.column1;
      :new.column2 := :old.column2;
      ...
      :new.columnN := :old.columnN;
    END IF;
  END;
  

  This is far from ideal from the point of view redo generation and from a perspective of maintainability, but it would prevent the change of location data.

  Another trigger approach would be to create a view on the table, create an INSTEAD OF trigger on the view and then publish your updates against the view. The INSTEAD OF trigger can determine to apply changes to the base table or not, whether to discard the changes or if you want to record changes in another table.

• Problem with shutter button INSTEAD of

  Hello world
  
  I have a v_test of view. Create an INSTEAD OF trigger on it. When I try to insert on the view, it is throwing an error like ' ORA-00036: maximum number of levels SQL recursive (50) exceeded "." Please help me how come from there.

  CREATE OR REPLACE TRIGGER TR_V_TEST

  INSERT INTO V_test VALUES(107,'VEERA',20000,30);
  END;

  Thanks in advance!
  
  Thank you
  Florian...

  CREATE OR REPLACE TRIGGER TR_V_TEST
  INSTEAD OF INSERT ON V_test
  FOR EACH ROW
  BEGIN
  INSERT ITNO V_test VALUES(107,'VEERA',20000,30);
  END;
  

  The problem is in the above definition of the trigger.

  This will result in recursive SQL because each time that you insert in the view, the trigger is fired and in your body to trigger you try again to insert in the same point of view.

  INSERT ITNO V_test VALUES(107,'VEERA',20000,30);
  

  the above should be replaced by another table

  So you're creating instead of trigger directly on the view from above (the original name of the table)? Let me know if this isn't the case.

  OWM does not support INSTEAD of triggers. Instead of triggers need to be defined on a view and the only objects that can be activated version are tables. However, I see nothing in your description that says to an INSTEAD of triggers. What you try to do so should be able to finish the level triggers table row dml insert/update/delete. You would simple create triggers on the table before EnableVersioning or add them during a session of beginDDL/commitDDL, and they would be then implemented as PL/SQL procedures inside the inside instead of triggers that we create. They are not defined on the table _LT.

  After you create the trigger, you would be able to use dbms_wm.setTriggerEvents to specify the events you want relax to fire to.

  Hello

  Whenever you have a problem that raises an error, display the full error message; do not paraphrase just part of it.

  In the triggers line numbers from the first statement DECLARE or BEGIN, so line 22 of your trigger is:

  SELECT categorie INTO cateogrieLocataire FROM Sportifs WHERE ns = new.ns;
  

  You are missing a colon before 'new': it should be:

  SELECT categorie INTO cateogrieLocataire FROM Sportifs WHERE ns = :new.ns;
  

  A FOR EACH ROW trigger on tenants cannot ask tenants. It's a shame: there are many useful things, you could do if that were allowed, but it's not.
  I'm not sure of what all queries. At least one of them:

  SELECT  COUNT (ns)
  INTO    num2
  FROM    Locataires
  WHERE   nLogement = :new.NLogement
  AND     nomBat    = :new.nomBat;
  
  IF num2 = 2 THEN
      raise_application_error(-20000,'accomodation full');
  

  can be replaced by a UNIQUE constraint. (Constraints are better than triggers, in any case.)

  If you can't do what you want with constraints, you can leave anyone directly INSERT or update the table: force them to use a procedure stored instead. You can have an INSTEAD OF trigger on a view, which is essentially the same, but allows you to use DML commands.

  If you need help, post some sample data and some examples of DML operations that must be allowed, given the data and some examples of DML operations that should not be allowed.
