  Hi Vincent,.

  I think that you have not worked on adf 12.1.3.  In adf 12.1.3 you don't have to explicitly create the association. When you create the EO to your table, Association xxxxFkAssoc, will be created by ADF12.1.3 for you automatically. Please try this and do not answer anything... You can also follow the links below. I solved the problem by using the following link

• Indexes and foreign keys

  Hi, we have a RAC Oracle 10 g 2 EE on SLES10.
  
  I have tables with 300.000.000 of records. These paintings clues because it access it takes very very slow. I check what he need an index for each foreign key. I have a lot of tables and I'm looking for some tools or SQL or similar phrases that tell me, tables for each foreign key index. For example, I need to know what a lot of index left complete me the process and that it.
  
  Table A
  ID (PK)
  B1_ID
  B2_ID
  C_ID
  D_ID
  ...
  ...
  
  (B1_ID, B2_ID) FK TO TABLE_B
  (C_ID) FK IN TABLE C
  (D_ID) FK TO TABLE_D
  
  
  I create the index in table A, table B, but I don't have the index for the table C and table.
  
  I have a lot of tables, with several foreign keys.
  How can I find out what indexes that I need to create?
  
  Thank you very much.

• Index and foreign key referring to itself

  Hello!
  
  I'm working on an application that uses a basket stored in a database. The shopping cart uses two tables:
  BASKET: Contains the common information for a shopping cart: the user is logged in etc.
  -Primary key: CART_ID
  
  CART_ROW: A line in the shopping cart, for example a new product to buy.
  -Primary key: ROW_ID
  -Foreign key: CART_ROW. References CART_ID CART. CART_ID
  
  On the code lines in the basket are taken by cart, as is modeled by the foreign key. There is a relationship, that we use in the code, but which is not modelled by a foreign key in the database. A line can be dependent on another line, which makes the other row a parent.
  CART_ROW has a PARENT_ID column that refers to CART_ROW. ROW_ID.
  Would you add a foreign key to PARENT_ID? Or are there issues to consider when it is a foreign key to the same table?
  
  Some time ago, we added the index, both ROW_ID PARENT_ID. The index on PARENT_ID could have harmful, since there is no foreign key?
  
  Best regards!

  I suggest to add the foreign key, it will not harm performance (except during an insert when there is validation of the foreign key). But it would avoid users to insert bad data / corrupted by code or directly on loggin in the database.

  Some time ago, we added the index, both ROW_ID PARENT_ID. The index on PARENT_ID could have harmful, since there is no foreign key?

  Index on parent_id would be dangerous if you do not use index after it is created (i.e. There is no application that can make use of this index).
  And if you decide to have a foreign key parent_id then I suggest to have too many indexes on parent_id because it would be at least useful when you delete a record in this table.

  Best regards!

• Unique key and foreign key in the view of materialzied

  Hello world
  I have one main site and 4 materialized view sites.
  In my main site, I did a main group that contains my tables participating in replication.
  I have a table that has a primary key, foreign key constraint unique.
  In my first materialized view site I did group for my opinion
  
  BEGIN
  DBMS_REPCAT. () CREATE_MVIEW_REPGROUP
  gname = > "hr_repg"
  Master = > "orc1.com"
  propagation_mode = > 'ASYNCHRONOUS');
  END;
  /
  
  BEGIN
  DBMS_REFRESH. DO)
  name = > 'mviewadmin.hr_refg ',.
  list = > ",
  next_date = > SYSDATE,.
  interval = > 'SYSDATE + 1/144',.
  implicit_destroy = > FALSE,
  rollback_seg = > ",
  push_deferred_rpc = > TRUE,
  refresh_after_errors = > FALSE);
  END;
  /
  
  Then I created the materialized view
  
  HR.test CREATE MATERIALIZED VIEW
  COOL OFF QUICKLY WITH A PRIMARY FOR THE UPDATE KEY
  AS SELECT * FROM [email protected]
  /
  
  BEGIN
  DBMS_REPCAT. () CREATE_MVIEW_REPOBJECT
  gname = > "hr_repg"
  sName = > 'hr ',.
  oname = > 'test ',.
  Type = > "SNAPSHOT."
  min_communication = > TRUE);
  END;
  /
  
  BEGIN
  DBMS_REFRESH. ADD)
  name = > 'mviewadmin.hr_refg ',.
  list = > "hr_test.test"
  Lax = > TRUE);
  END;
  /
  
  When I check the test (materialized view) table in the site of the materialized view to a primary key, but it has no foreign key forced unique having the base table and because my test materialized view can be changed I need to have these 2 constraint on my my materialized view. You have an idea why these 2 constraint were not created on my materialized view? And what should I do to have these two constraints.
  
  Thanks in advance

  On MView is created automatically only PK. Other constraints (check, not null, unique or FK) should be created manulay. Indexes also.
  But be careful with the FK.
  On ORACLE8, I found lines that are inserted to updatable mview back in deleted updating process, then inserted (downloaded on the main site). When FK is with on delete cascade that the lines of the child tables (mviews are removed too). And when the child mview is updated before mview parent you found the child missing lines.
  When CF is on delete restrict that you refresh the process fails.

• index and foreign key

  I just read an article on the index.

  Jonathan Lewis - during indexing

  The author says that if you update the primary key or a unique key at the end of 'parent' of the referential integrity constraint Oracle locks the "child" table to find the rows of children committed and uncommitted if a suitable index does not exist. After that he says do not create indexes 'foreign key '. I mean, there is a contradiction. What do you think?

• Primary key and foreign key

  Hi all
  
  I'm confused. If I create a primary key of table constraints, it willl create a unique index by default. If I create a foreign key, it also creates an index? of any kind?

  Laughing out loud. foreign key does not have a unique index on the table.

• Key Reg primary and foreign at the same table

  Hello
  
  It is - ok if create primary and foreign keys on the same table itself?
  
  For example:
  
  In a table X, I have two columns such as Codeunite and ParentUnitcode.
  Is it ok if create Mt10 as principal and ParentUnitcode as foreign keys in the table itself?
  
  The foreign key base table: OrganizationalUnit
  Foreign key columns: ParentUnitCode
  Primary/Unique key base: OrganizationalUnit
  Primary/unique key col: Mt10
  
  Can anyone answer me on that?
  
  Concerning
  Rajesh

  OWB,

  If the two tables are favouring a one-to-one relationship so there no need to have two separate tables and so you can have free referential foreign keys in the same table where the primary key.

• How to set the condition of rule to check the Primary Key, Foreign Key and Unique

  I use Oracle 10.2
  Could someone tell me please how to set the rule condition to check the primary key, foreign key constraint of uniqueness?

  Hello

  Primary key, unique constraints and foreign key are better applied using the native functionality of database constraint. If you like the rules to check if a key exists at the time of the evaluation, you can use a function defined by the user in a rule condition and this function can ask to turn the table keys.

  Hope this helps,

• How can I make sure that changes in a primary key (in the parent table) would also appear directly in the FOREIGN KEY in the child table?

  Forgive my question. I am very new to Oracle.

  How can I make sure that changes in the key primary supplier_id (concerning the supplier table) would also appear directly in the FOREIGN KEY (supplier_id) in the products table?

  Is that not all the primary key and FOREIGN KEY on?

  My paintings:

  I created 2 tables and connect to apply in the data base referential integrity, as I learned.

  CREATE TABLE - parent provider

  (the numeric (10) of supplier_id not null,)

  supplier_name varchar2 (50) not null,

  Contact_Name varchar2 (50).

  CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)

  );

  CREATE TABLE - child products

  (the numeric (10) of product_id not null,)

  supplier_id numeric (10) not null,

  CONSTRAINT fk_supplier

  FOREIGN KEY (supplier_id)

  REFERENCES beg (supplier_id)

  );

  I inserted the following text:

  INSERT INTO provider

  (supplier_id, supplier_name, contact_name)

  VALUES

  (5000, 'Apple', 'first name');

  I expect that the supplier_id (5000) to the provider of the table also appears in the products table under key supplier_id having the same value which is 5000. But this does not happen.

  How to get there?

  Thanks in advance!

  Hello

  What is a foreign key in Oracle?

  A foreign key is a way to ensure referential integrity in your Oracle database. A foreign key means that the values of a table must appear also in another table.

  Ok!??

  What is now the right way to implement referential integrity in your Oracle database that the values of a table must also be included in another table?

  A foreign key referential integrity indeed enfore in ensuring that the value in the child table must have a corresponding parent key (otherwise you will encounter an error, as evidenced by "SomeoneElse"). However, it will never automatically insert a row in the other table.

  If you are looking for a solution that automatically inserts a record in the other table, maybe you should go for triggers:

  See:

• problem with the locking insert and delete between two linked tables help please.

  Hi guys I have a problem with a table of locking in Oracle forms, but when I try in SQL happens here too many users. I was wondering if anyone can shed some light on this?
  
  I created two scenerios one that works and is not based on the primary key and foreign key constraints (but one that works is not possible for us because it would mean change design table that we can not do).
  
  I've hardcoded in 1127,1128 number to make it easier (in reality it is a sequence)
  
  OK scenerio one (our scenerio)
  
  two tables
  

   CREATE TABLE testSFLABPR 
     (     LABP_REF_IRN VARCHAR2(25 BYTE), 
       LABP_REF_REF VARCHAR2(30 BYTE), 
       LABP_REF_SL NUMBER(8,0), 
       LABP_CONFIG_ID NUMBER(8,0),
        CONSTRAINT PK_testLABPR_IRN_SL PRIMARY KEY (LABP_REF_IRN,LABP_REF_SL)
     ) ;
  
   CREATE TABLE testSFLABP 
     (     LABP_IRN VARCHAR2(25 BYTE), 
       LABP_OPNO NUMBER(3,0), 
       labp_no NUMBER(8,0),
        CONSTRAINT PK_testSFLABP PRIMARY KEY (LABP_IRN, LABP_OPNO, LABP_NO) ENABLE, 
        CONSTRAINT testFK_SFLABP_SFLABPR FOREIGN KEY (LABP_IRN,labp_no)
         REFERENCES TESTSFLABPR (LABP_REF_IRN,LABP_REF_SL) ENABLE
     ) ;

  OK now session is done the following
  

  DELETE FROM      testSFLABPR     WHERE   LABP_CONFIG_ID            = 1127;          
                 
  INSERT INTO testSFLABPR(
          LABP_REF_IRN,
          LABP_REF_SL,
          LABP_REF_REF,
          LABP_CONFIG_ID
          )
          VALUES
          (
          'SOPENSHELVING',
          1127,
          1127||'CF Route',
          1127
          );
          
  INSERT INTO testSFLABP
        (
        LABP_IRN,
        LABP_OPNO,
        LABP_NO)
  VALUES (
  'SOPENSHELVING',
  1,
  1127);

  session one remains in this State.
  
  second session now does the following

  DELETE     FROM testSFLABPR     WHERE   LABP_CONFIG_ID            = 1128;     

  second session is now locked until a commit or rollback occurs.
  
  If I run the exact scenerio even with only a primary key on the table without locks held
  

   CREATE TABLE testSFLABPR 
     (     LABP_REF_IRN VARCHAR2(25 BYTE), 
       LABP_REF_REF VARCHAR2(30 BYTE),

        CONSTRAINT PK_testSFLABP PRIMARY KEY (LABP_IRN, LABP_OPNO, LABP_NO) ENABLE, 
        CONSTRAINT testFK_SFLABP_SFLABPR FOREIGN KEY (LABP_IRN)
         REFERENCES TESTSFLABPR (LABP_REF_IRN) ENABLE
     ) ;

  INSERT INTO testSFLABPR(
