• How can I update the primary key column

  Hello
  Can you suggest me best workaround/algorithm for task below:
  
  (Oracle 10g, Solaris OS.)
  Location:
  Table a primary key column P 'Code', tables children F1, F2,..., reference to F15 "Code_P' foreign key column"P.Code"column, and we do not know which of the child tables data available for a particular value"P.Code.
  Task:
  Change the value "P.Code" from 100 to 200. So that the result would be that record P [Code = 100] should be updated:

  update P set
  Code = 200
  where Code = 100;

  And child tables 'Code_P' column should be updated as:

  update F1, F2, .., F15 set
  P_code = 200
  where P_code = 100;

  The best solution would be that you can easily repeat this task.

  Will there be FK constraints in place?
  If so, you may need to modify them so that their application may be temporarily deferred.

  The gameplan would be something like this:

  -Making of CF can be deferred, immediate departure.
  -Alter FK set delay.
  -Update of Parent table.
  -Update of the children tables.
  -Immediate constraints set

  Prashant

  Prashant,

  You must assign new values to null values. You can use a sequence to produce the figures in this column.

  Select max (your_unique_column) from your_table; -find the maximum value of this column, so you can start the sequence of this number.

  create sequence seq_for_your_table with XXXX - value max + 1 you have found

  Update your_table set your_unique_column = seq_for_your_table.nextval () where your_unique_column is null

  You can create a primary key on this column.

• Returns the primary key of the new line (generated by the trigger) to an insert procedure

  Hello
  I have a table with a primary key (number), which increases with the trigger
  I use a procedure to insert data into this table
  How can I find the primary key of the row inserted to this procedure?

  When you make use of the insert:

  INSERT .... RETURNING key_column INTO variable;
  

  (where key_column is your key on the table column and variable is a variable to store the value of the same data type)

  to get the value in a variable.

• See the primary key

  I have a form on a report and the primary key is not visible. In its place in the column is the button change. How do we guarantee that the primary key is visible as well as change the button?

  jclarke,

  There are two ways to do it. If you hold the button change then the best thing to do is to remove the 'link' information associated with the primary key column (remember / note the details for the next step) so that it displays normally.

  Then go to the page report attributes and in the menu on the right tasks, select 'add column link '. Configure it as the column ID is.

  Kind regards

• Automatically fill the primary key

  We have Oracle database 10g. I've added a primary key column to my deo_language_resources_t of table with the following logic:
  
  -- 1. create sequences
  create sequences eod_lr_seq
  Start increment by 10 by 5
  MinValue 10 nomaxvalue
  NoCache;
  
  -- 2. Create the primary key column
  ALTER table deo_language_resources_t
  ADD NUMBER RESOURCE_ID;
  
  -- 3. Fill the pk
  Update deo_language_resources_t
  Set id_ressource = eod_lr_seq.nextval
  where id_ressource is null;
  
  -- 3. Create the primary key constraint
  ALTER table deo_language_resources_t
  Add constraint resource_id_pk key (resource_id) primary;
  
  insert into deo_language_resources_t
  (first_name, last_name, id_ressource)
  values ('John', 'Doe', eod_lr_seq.nextval);
  
  The last INSERT statement successfully a line inserted into the table and populated by id_ressource with the next number in the sequence eod_lr_seq. Ok.
  
  Is it possible to set a constraint on deo_language_resource_t so that when I INSERT a line the id_ressource is automatically set to eod_lr_seq.nextval? It is possible to define a trigger and resembling the logic of the trigger? The insert statement would be like:
  
  INSERT INTO deo_language_resources_t (first_name, last_name) VALUES ('John', 'Doe');

  create trigger deo_language_resources_trigger
  before insert on deo_language_resources_t
  for each row
  begin
  select eod_lr_seq.nextval into :resource_id from dual;
  end;
  

• How to fill out the table foreign key to the primary key form

  Hi all

  I'm stuck in this problem for 3 days, and I'm about to research and implement solutions on the internet.

  I have two tables

  create table prim (a number primary key, b varchar2 (100));

  create table CHILD (a number references (a) prim, varchar2 (100)) c;

  I created a page for PRIM table.

  = page name form on PRIM2

  I have manually two columns for the CHILD table to know

  P26_A_1 (for the primary key in the CHILD table)

  P26_C (for the column in the CHILD Table c)

  now when the user clicks on the button CREATE, a row must be inserted into the child table.

  I want to assign the P26_A to P26_A_1 during the validation process, so that a line must be inserted into the PRIM table as well as in the CHILD table.

  How to do this?

  I downloaded my application page in https://apex.oracle.com

  my workspace identifiers are inferior to

  name of the workspace = IMBERT

  username = demo

  password = demo

  kindly guide me.

  Thank you.

  Hello

  I created a new page (page 30) similar to your page and added the insertion of the child. It just check the page and code. It works now, when you insert the prim file is triggered a second trial which inserts the child record manually.

  On page 26 it was some sort of mistake, was easier to create a new as it was almost a standard form.

• How to extract the values of the line full in the bean to support using the primary key

  Hello

  I have a table that has columns as plant_name, business planner email id and identification of email resident engineer. Here, Plant_name is the primary key.

  Hi Sneha, you've written code for it

  you have found the current line and the primary key then this line, then why you not not using this same rank to get the other attributes?

  NewRow row = lBinding.getCurrentRow ();

  String aamplant1 = (String) newRow.getAttribute ("Plant");

  String businessPalnner = (String) newRow.getAttribute ("business_planner"); Returns the value of the same line
  

  Engineer in String = (String) newRow.getAttribute ("engineer");

  
  

  OR if your condition is like that-

  you have a primary key field value, but you do not have the corresponding line, then you can get that line and it's attribute by using the primary key value

• How to use a Select list on a second primary key column in a tabular presentation?

  Hello
  
  I created a tabular presentation located on the details page of the user (form), that allows to manage roles for this user.
  
  The shape of table contains 3 elements:
  -> a checkbox
  -> user (PK) column is hidden, and its default value is generated by a function pl/sql (to submit the time), which refers to the element to username.
  -> the role of the column is displayed as a named select list LOV: add you a line, choose a role, submit, etc..
  
  But my ROLES table (not created by me...) contains 2 columns: USER and GRANTED_ROLE.
  The USER is the primary key, but a user can have multiple roles (= one line per role).
  GRANTED_ROLE is the second primary key, so that we can differentiate between one line of another.
  
  At the moment my tabular form has only one primary key (USER), so the GRANTED_ROLE can display as a list select.
  But, for this reason, in my opinion, remove the button do not work: all the lines of the user have the same key, so when I select a few lines to remove these, all lines in the form of tables are deleted.
  
  I don't know how my button Delete could recognize the subkey to remove only selected rows...
  Or maybe I should use a different type of region?
  
  Thanks for your help!
  Fanny

  In the process of ApplyMRD, try to specify the 'secondary key' column in the section "Source: Multi line Update and Delete"to the second column key in tabular form.»

  I have not tested this with your situation, but worth it.

• How to get generated automatically the primary key to create procedure

  I have a service of physical data corresponding to a table named ACCOUNT. The primary key on the table is called ACCOUNT_ID. There's a trigger on the database which generates the primary key value and adds it during an insert. I would like to have this primary key value returned by the procedure of creation of physical data service. Any ideas on how this can be done? Thanks in advance.

  as the primary key automatically obtained by ODSI leave a sequence in the DB and used during a procedure for creating

  Go to the design for the physical data service view

  Click the column which is filled from the sequence.

  In the Properties tab (bottom window), under general, for automatic numbering, click the 'Value' column, select sequence. You get a noise on some things have changed, just click OK. With AutoNumber = sequence setting, this column appears as optional (question mark).

  Just below that, for purpose of sequence, type the name of the sequence (you can also specify MYSCHEMA. In case the sequence SEQUENCE_NAME is under another schema).

  When you create objects SDO - leave the update vacuum column.

  that is if he were CUSTOMER_ID, your client would look like this...

• APEX do not allow to change the lines of the columns that are the primary key?

  I have pictures:
  http://img508.imageshack.us/my.php?image=21269582oe8.jpg
  
  
  Book (id_book - 'Primary key', title, year); book_author (id_author id_book - 'Primary key', - 'Primary key'); author (id_author - "Primary key", name)
  
  
  
  I created a new page-> Form-> form of 'author' table because I want to add new authors, modification and deletion. During the creation of this page, I have chosen column 'id_author' as '1 primary key column' and everything is OK (I can't edit the 'id_author' column - this column is autoincrement and I can change the 'name' column).
  
  BUT I also created a new page-> Form-> table for table "book_author" because I like to write numbers like id_book and id_author, change and remove them (so add relations between tables: book, book_author and author). During the creation of this page, I have chosen column 'id_book' as '1 primary key column' and 'id_author' as 'column primary key 2'. And on the Web site, I can't edit these fields. And I can not add also new line because I see in each new line: (null).

  Edited by: user10731158 2008-12-20 11:40

  Column unique and not meaningful if you ever want to update. In the case of your example, you need to add an ID column in the intersection of book_author table. Honestly, I was so blown away (and pleasantly surprised) by the absence of rebuttal and the "thx" I advanced and set up an example of how I would define the book_author table:

  create table  book_author
     (id varchar2(32),
      book_id varchar2(32),
       author_id varchar2(32),
       modified_on     date,
       modified_by varchar2(255),
       constraint book_author_pk primary key (id),
       constraint book_auth_book_fk foreign key (book_id) references books(id),
       constraint book_auth_author_fk foreign key (author_id) references authors(id)
       )
  /
  
  create unique index book_author_uq on book_author (book_id,author_id)
  /
  
  create or replace trigger  biu_book_author before insert or update on book_author
  for each row
  begin
       if inserting then
            :new.id := sys_guid();
       end if;
       modified_on := sysdate;
       modified_by := nvl(v('APP_USER'),user);
  end;
  /
