• trigger on the table will update the same table

  I have a requirement, once the record is inserted into the table that I have to update this record value. To do this, I wrote after the trigger insertion, but faced with the question as NO DATA found... Please tell us how right?

  Here are the steps I followed

  create table test_1 (numb number , varchar2()10));

  create or replace trigger test_tri

  AFTER INSERT OR UPDATE

  ON test_1

  REFERRING AGAIN AS NINE OLD AND OLD

  FOR EACH LINE

  DECLARE

  number of your;

  Start

  test_pro (:New.Numb,:New.Name);

  end;

  create or replace procedure test_pro (abc IN number, CBD IN varchar2)

  as

  PRAGMA AUTONOMOUS_TRANSACTION;

  number of GG;

  Start

  If abc is not null then

  Select numb in gg test_1 where numb = abc;

  dbms_output.put_line (' gg value if bock..'|) (GG);

  Update test_1

  name of the game = CBD | ABC

  where numb = abc;

  END IF;

  commit;

  end;

  Insert in test_1 values () 80 'RUN'); - reuslt found any EXCEPTION

  When the after trigger run? is it after insertion and before validation?

• Problem with trigger on the table

  Hello
  
  I have the table TEMP AS (NUMBER of SNO

  DATE OF UPDATE_DATE)
  
  I want to create the trigger on this table as each time that it is updated in the STATE of temporary table UPDATE_DATE updated columns.
  I am creating the trigger using the PRAGMA autonomous transaction, but it does not work with that and withouht PRAGMA.
  With PRAGMA I get the error message ' ORA-00060: Deadlock detected while you wait resource. "

  Hello
  This is not a valid forum for questions like that. Thank you for using {forum: id = 75} forum. However, you can use following code:

  
  create or replace trigger xx
  before update of state
  on cabasys.temp
  for each row
  begin
  :new.update_date := sysdate;
  end;

• After an Insert with DML trigger on the table of the object?

  I am trying to implement e-mail notifications, so I created a procedure that accepts the argument of id. In the procedure, it queries the table and send mail based on the result set. (in the trigger, I pass the value of: NEW.id). The procedure then queries the table for this line id.
  
  First of all, the update after, I received the error:
  
  ORA-04091: table is changing, the trigger/function cannot see ORA-06512
  
  So, I was advised to do in the declare block: pragma autonomous_transaction; I did, and that solved the problem here. THEN I did the same thing in the insert after trigger, but then I get the error:
  
  ORA-00060: Deadlock detected while you wait resource ORA-06512
  
  I asked our DBA and it says that you are not able to query the table on which the trigger is a topic of. I thought that it would be possible since his after insert or update?
  
  Can anyone offer any suggestions? :)
  
  Thank you
  Trent

  SB has given you the first part of the answer I wrote but here's another consideration.

  Suppose you make an insert...
  and the trigger is activated...
  and the message is sent.
  and then the transaction is cancelled...

  There are on the way to recall the message.

  This is another example of why, I think, Tom Kyte, refers to triggers as evil.
  I would recommend that you are looking for another strategy, possibly using DBMS_CHANGE_NOTIFICATION.

• LOV in richeTableau resets the value after the deletion of rows from the table

  Hello. I'm on 11g R2

  I have a table with columns in the box and a button in the toolbar that removes the lines checked

  I have build it based on the following article in her string code

  http://www.Oracle.com/technetwork/developer-tools/ADF/learnmore/index-101235.html

  
  

  When I run the "delete" button I execute the following code (taken as is article)

  
  

  public void deleteSelectedRows() {}

  create a second line, the value do not affect all lines

  used in ADF

  Set of rows duplicateRowSet = this.createRowSet ("duplicateRowSet");

  first row to avoid "the attempt to access the value of lines."

  exception line was dead.

  duplicateRowSet.first ();

  retrieve the current row of the table for after

  re-running the VO

  Line currentRow = this.getCurrentRow ();

  Boolean currentRowDeleted = false;

  get all rows that have the transoent attribute

  "MarkForDelete' set to true

  Row [] rowsToDelete =

  duplicateRowSet.getFilteredRows ("MarkedForDelete", true);

  If (rowsToDelete.length > 0) {}

  run only throizgh this code, if there is something to

  delete

  for (line rw: rowsToDelete) {}

  If the row is marked as the current in VO, ts value

  Boolean flag

  If (rw.getKey () .equals (currentRow.getKey ())) {}

  currentRowDeleted = true;

  }

  remove the line - do not yet commit

  RW. Remove();

  }

  rerun VO

  this.executeQuery ();

  reset the current line if it has not been removed

  If (! currentRowDeleted) {}

  this.setCurrentRow (currentRow);

  }

  duplicateRowSet.closeRowSet ();

  }

  }

  "MarkedForDelete" is a transient attribute used to mark the line delete

  The lines are removed very well.

  The problem is with lines that I do not delete.

  For example I LOV column. I chose the value LOV in a few lines, and after that choose to delete several lines (not the same lines where I modified the LOV) but some other lines.

  After I click "delete", the lines that I marked to remove deleted indeed, but the value of the LOV in other rows (I have not scored for delete) are disabled.

  How to preserve value LOV so it will remain also after I deleted some lines?

  P.S. I've tried autosubmit = "true" - it did not help

  It is expected because I see that you rerun the query.

  Once you re - run, it retrieves from the database again. Thus, your values are lost because they are not posted.

  I don't think that run query is necessary, try to have a programmatic part trigger on the table after you remove all of the lines.

  Thank you

• primary key for the table

  I have a Gr_order table that was settled long ago, and now he needs to be filled
  with some more search data.
  
  "Orderid" is a primary key for the table, but the question is how can I insert "orderid" in the insert statement in the procedure. I couldn't find any name sequence. There are 1230
  documents that must be inserted.
  

  Desc Gr_order
  Orderid  Number Primary key
  Desc     Varchar2

  INSERT INTO gr_order (orderid,desc)  
  VALUES (???, upper(each_pom.desc);

  Thank you
  Sandy

  You can find the code that inserts into the table and see if it uses the sequence ;-). A sequence is not 'attached' to a particular table - this is the insert statement to determine whether a sequence should be used.

  You can check if the table has a trigger - some developers like to emulate the behavior of MS - sql server by having a trigger on the table that selects in a sequence. If it has such a release, then you just do your insertions without specifying order_id. But if the table does not have such a release, then you cannot know if the table was originally filled using a sequence or not (unless you can find the instructions for inserting somewhere).

• for relaxation: where is the table created by the Wizzard users create in the APEX?

  Hello everyone and Tony in particular since it was followed and mentoring my progress on this.
  
  Well,.
  
  Here we have 2 things:
  
  
  
  (1) when the wizzard of Administration > database > manage users creates a user. Where is the table it creates? What name does have? Why is it not visible in the object browser? I need the name of this table to put it on my trigger (I called users_table)
  
  
  
  (2) how to do that whenever a user connects, his formerly generated by the trigger sequence is used by a State to extract personal data (it's sort of VPD) in this case would be, how do you know what surrogate key, we need to call. To do this, I think, the thing would be to request the: = APP_USER (that was created in step 1) and each APP_USER will surrogate that are associated with this key.
  
  
  
  I set up a simple trigger, but just the substring of the concatenation of the given username, the system randomly generated pwd up to 12 characters.
  
  
  
  CREATE OR REPLACE
  GENERATE_SEQUENCE RELAXATION
  AFTER INSERT ON USERS_TABLE
  FOR EACH LINE
  BEGIN
  insert into users_table (surrogate_key)
  values (SUBSTR (¦¦ username password), 1.12);
  END;
  
  
  but as I said, this users_table must be the table where the wizzard to create users stores its data,... .but where is this table?
  
  
  Thank you very much

  Hello

  (1) create a table and then start filling in

  I think you need to have a custom table of your patients (and users), say,

  CREATE TABLE patients
    (
      "USER_ID"   NUMBER,
      "USER_NAME" VARCHAR2(100 BYTE),
      "FIRST_NAME" VARCHAR2(100 BYTE),
      "LAST_NAME" VARCHAR2(100 BYTE),
      "PASSWORD"  VARCHAR2(4000 BYTE),
      "CREATED_ON" DATE
      CONSTRAINT patients_PK PRIMARY KEY ("USER_ID")
    );
  

  you need to build customized in your appl authentication and do not use the Apex or Db authentication.
  To do this, you must do this table in the schema that is used in the analysis of your application's schema.
  And you need create the function custom_hash like this:

  create or replace
  function custom_hash (p_username in varchar2, p_password in varchar2)
  return varchar2
  is
    l_password varchar2(4000);
    l_salt varchar2(4000) := '55PSP4P78JLDQ2AMBXQ60DW9OW7G9Z';
  begin
  
  l_password := utl_raw.cast_to_raw(dbms_obfuscation_toolkit.md5
    (input_string => p_password || substr(l_salt,10,13) || p_username ||
      substr(l_salt, 4,10)));
  return l_password;
  end;
  

  (2) then build the trigger when it detects that I completed a line
  It generates this sequence AND inserts it into another table (as you say, I could not put it in the same table)

  users must register themselves?
  Or register?
  Then you must create the free registration form or a form where you fill in your table above users.

  I think that your user_name must be unique. Put a Unique about this strain.

  When creating the patient button is pressed, then the above table is filled (you must and name, user in the form fill password)
  You must calculate USER_ID, user_name, password and created_on, this can be done in the trigger

  create or replace
  TRIGGER patients_trg_bi
    before insert on patients
    for each row
  begin
  if :NEW.USER_ID is null then
      select patients_seq.nextval into :NEW.USER_ID from dual;
  end if;
  
  if :NEW.CREATED_ON is null then
      :NEW.CREATED_ON := SYSDATE;
  end if;
  
  if :NEW.USER_NAME  is null then
      :NEW.USER_NAME  := :NEW.LAST_NAME || :NEW.USER_ID;
  end if;
  
     :NEW.PASSWORD := custom_hash(:NEW.USER_NAME, :NEW.PASSWORD);
  
  end;   
  

  you create the sequence of patients_seq

  In this case the surrogate key be hashed password.
  And you can use it by selecting table using patients: APP_USER
  that is when the user is connected to his USER_NAME, variable APP_USER is filled

  (3) then, the SQL query would recover this surrogate_key and show as connected individual data.

  Yes, when the user logs on, the key is populated by users based on table: APP_USER
  using

  select password
  from patients
  where user_name = :APP_USER;
  

  You must understand how EVP can be implemented at the Apex.

  You can use any application for this SURROGATE_KEY say

  which is calculated by Application of calculation on the new Instance

  4) but in order to know what to ask, surrogate key should be a key with the substitution APP_USER connection

  is that correct?

  Yes. You have the info from the users table

  Do you have examples of Applications Apex somewhere.
  If you use Apex 2.1, you can install it from the repository and if you have 3 Apex, they are normally automatically installed if you create the new workspace.

  You can use it a lot to manage users.

  Concerning
  Oleg

  BTW,

  Alvaro,
  Yo have your appl?
  If you sent your Db and tables all the Pl/SQl, as well as application Apex, you have for me by email, I can check and make/suggest improvements
  (For free, of course)
  I need to check what you did there, otherwise it seems to be a very long subject.
  Well, I have the time to discuss

  Yes, you can make the trigger like this

  CREATE OR REPLACE
  GENERATE_SEQUENCE RELAXATION
  AFTER INSERT ON USERS_TABLE
  FOR EACH LINE
  BEGIN
  insert into GENERATED_SEQUENCES_TABLE (lastinserted_name, surrogate_key)
  values (SELECT name from USER OF USERS_TABLE WHERE USERID..., SUBSTR (lastinsertedname¦¦ password), 1.12);
  END;

  but where the values are made here
  SUBSTR (lastinsertedname¦¦ password), 1.12

• How to add data to the table changed in sql developer at Apex and vice versa

  Hello

  I had tables of database with sql developer. But now, I have modified the database (new tables added + changed the data in the tables). However, in the Apex, I the old database. Is it possible to get the new Apex database with the data of the table changed so this database in both places (sql and apex developer) is exactly the same... Also the other way around.

  Thank you

  The database schema that contains the tables, is it associated with the workspace even you are searching through the APEX product t development?  Why I'm asking is, if they are the same schema, the tables that you MODIFIED should be appear in the sql for APEX workshop part.  Now reports and forms will NOT see the changes (unless you have actually added or updated definitions for column).

  Can you explain what exactly you were doing the SQL Developer to the tables in your schema?

  Thank you

• Apex 5.0.2 error when changing the table name in the treatment of automatic line of process (process row)

  Hello

  I need a little help...

  For some reason, I have to change the underlying table for a treatment of automatic process (process Row) line (form).

  Although such a change is possible in the designer of the page (under "settings") Apex does not recognize the new name of the table, but seem to rather use the name of the original table "old."

  Pretty strange (new/modified) (the new table columns) are (correctly) error message.

  For example, the 'old' is: TABLE_1 and TABLE_2 new.

  TABLE_2 has a new COLUMN_NEW column (and corresponding P1234_COLUMN_NEW page element exists)

  Then the error message says something like: not found COLUMN_NEW column in TABLE_1. Althougt I changed the table to be TABLE_2.

  Maybe it's a bug or I do something wrong about this?

  Thank you in advance!

  André

  OK, just to get some - you changed the name of the table twice:

  -Rendering of section--> Page1234: Pagename--> pre-rendering--> after the header--> process of--> line from TABLE_2

  -Treatment article--> treatment--> process--> process of line from TABLE_2

  I thought, that always seek you the line of TABLE_1

  Also what yo mean "looking forward on how to proceed? Do you want to or created for use/consume in your Oracle APEX application hosted RESTful web services?

  If Yes, in your Application, you must create a RESTful Web Service reference -> shared components. Then, create a form/report based on Web Service reference.

• Non riesco a generare I trigger by the journal tables

  Buonasera,

  utilizzavo tables version 4.1.1 di Data model e riuscivo a generare I trigger by the newspaper, pero utilizzava sempre he nome di table "emp2."

  Nelle note della versione 4.1.2 release it era scritto che he bug era stato solved, pero adesso non riesco più a generare I trigger by the journal tables.

  You can help?

  Grazie

  Hello Davide,.

  you are able to run the generation of 'test' as he explained here Oracle SQL Developer Data Modeler 4.1 user - defined DDL generation using transformation scripts

  Do you have a location in "preferences > Data Modeler"-"types of default system directory" - If there is a defined directory it can DM puts the script from that directory - scripts are in the file - dr_custom_scripts.xml. "»

  If you have not changed the scripts distributed with Data Modeler (or add new ones) so you can copy this file in the directory datamodeler\datamodeler\types of DM 4.1.2 installation to the directory defined in the preferences.

  In fact the problem in 4.1.1 DM was in the script itself always putting this 'EMP2' name in the definition of the trigger - line 66 should be modified in order to obtain valid results:

  old line 66:

  "WE DELETE emp2 for each line \n" +

  new line 66:

  "WE DELETE" + lname + ' for each line \n"+"
