  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

  I use LR5.7 based on Windows 7 and got a few pictures 150 000 in a catalugue. Could import, export and rendering speed be increased, if I store the LR catalog on the same drive as my photos? Today, the program, the catalog and photos are all on different drives.

  Import and export and rendering speed depends on the CPU. The disk contributes only a negligible amount to import and export and rendering speed. You would spend more time to pass the photos that you would gain in speed.

  You gave * of * SCOTT * at * SHARMA.  The grant received by SHARMA not getting exported when you export SHARMA.  So, it is not imported when you import SHARMA.  If you did an export and import of SCOTT before SHARMA, the award of the cross-schema would have also been imported.  (Subsidies granted by a user are exported with the user, the subsidies received by a user are not exported with the user).

• Old e-mail folders Outlook Import/Export and content to new computer

  bought a new computer HP laptop with outlook 2013, have not been able to export my old laptop HP 2010 outlook e-mail folders to outlook 2013 using the export/import functions. is it possible and if so how would run.

  If you review the Office/Outlook groups, you would see that Import/Export is rarely recommended.

  Assuming that pop e-mail accounts, not Exchange

  On the current PC, with closed outlook copy outlook files from media, data in a repository of Documents on the new PC.

  Then in Outlook, find and open the data file. You then have options as to what you do with the old data, IE copy in the set of current data files or leave as what.

• 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?

• 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.

• 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?
  
  
  Thank you very much
  
  Kinz

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

• CFTransaction, several inserts and foreign keys

  Here is the joke of what I want to do
  
  < cfset commitit = yes >
  < cftransaction action = start >
  < cftry >
  < cfquery >
  making my first insertion on the main table - primary key is the unique sequence number
  < / cfquery >
  < cfquery >
  do my next insertion in the second, but it has a foreign key to the intial insert constraint
  < cfquery >
  < cfquery >
  do my next insertion in the third table, but it has a foreign key to the intial insert constraint
  < cfquery >
  < cfcatch >
  < commitit = no >
  Rollback
  < / cfcatch >
  If commitit = yes
  commit the changes
  endif
  < / cftry >
  < / cftransaction >
  Problem is when I try to insert the record in the second table, the first record (parent) is not here because no validation has yet arrived. I get a foreign key error. I want to do within a transaction so that I can do a restore if there are questions. Is it possible to do in a cftransaction?
  

  I want to thank you all for your answers. The code I had was OK. I kept changing the code for serialization, because it makes sense in this case. I needed to get back to the basics - my definition of foreign key was in trouble. Thanks to you all.

• 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:
