• 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:

• I am trying to create a sequence to be used as a primary key in an Oracle table

  Hi guys
  
  I ODI version 10.3.5 and I'm trying to create a sequence that fills with row_id for a table. The schema is a database.
  And I want that this element will be the primary key of the table that is responsible to run the interface but I get questions.
  
  So please advise me.

  Hello

  Can you please provide the following details:
  1. What is the area of the execution of your sequence? Is it source, scene or target.
  2. what IKM you use (hopefully, you run the sequence in the staging or the target)?

  My understanding is when you check in not Null, all your lines going to the error table. So it gives no error.

  When you uncheck the not Null, it is in error because the database does not Null values in the primary key column.

  You can do the following to check if your sequence is working properly.
  Try to write an Insert Select query to DB and run it and see if it works properly.

  i.e.

  Insert (EMPL)
  EMPNO,
  ENAME,
  EMPLOYMENT,
  BISHOP.
  HIREDATE,
  SAL,
  COMM,
  DEPTNO
       
  )
  Select S_EMPNO. NEXTVAL,
  ENAME,
  EMPLOYMENT,
  BISHOP.
  HIREDATE,
  SAL,
  COMM,
  DEPTNO
       
  from EMP

  or if you can provide your query in this format, it will help find the question quickly. Please also indicate the KM.

• View of Materlized primary key and primary key in the master tables

  We use the Oracle 11 g 2 and I created a view on several paintings of master materlized. The paintings of masters all have the primary key, but I understand not all primary key columns in the query definition.
  According to Oracle manual e10592

  Specify WITH PRIMARY KEY to create a primary key materialized view. This is the default ....
  The master table must contain an enabled primary key constraint, and the defining query of the materialized view 
  must specify all of the primary key columns directly.

  My MV created OK and works. My question is what can be the impact on my MV? Could he hit to performance. It takes 40 minutes to the MV should be created and 5 minutes to refresh the one line insert in each table of mater. I would like to see it refresh in a few seconds.

  Retrieve the lines of the mview is purely a function of the number of lines and indexing on the mview himself. Mview refreshing at the time of the wall depends on the quality of the query used to refresh the mview. If you include the PKs of the source table in the mview matter or not, here. What matters is the execution of the refresh request path. Is it okay to indexation on the underlying tables to support the joints. Did you use mlog$ _s to allow a quick refresh - mlog$ _s are still usable for your mview. There are a number of possible causes for your problem and we do not have enough information to make an estimate of the problem.

  BTW, if the mview could refresh in a few seconds without mlog$ _s, probably unnecessary a mview.

  Make sure user name used in remote_db database link has select privileges on Journal of MV. On the issue of db source:

  SELECT LOG_TABLE FROM DBA_MVIEW_LOGS WHERE LOG_OWNER = 'TABLE1-owner' AND MASTER = "TABLE1";

  This will give you MV table the journal name. On the issue of target side:

  SELECT * from MV-LOG-NAME@remote_db;

• 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.

  Please suggest.

  First of all, thanks for posting the code that allows us to reproduce your test. It is essential for such problems.

  Because the primary key is global you will not be able to use

  INCLUDING INDEXES
  WITH VALIDATION;
  

  And you need to add the primary key to the temporary table

   ALTER TABLE DEMO_INTERVAL_DATA_LOAD_Y ADD CONSTRAINT IDX_DEMO_ROLL_Y PRIMARY KEY (ROLL_NUM);
  

  The Exchange will work. You must rebuild the primary key after the Exchange.

• ORA-02449: unique/primary keys in table referenced by foreign keys

  ORA-02449: unique/primary keys in table referenced by foreign keys

  solution

  This error happens when the foreign key of a table is referenced by the primary key of the other table.

  If you want to remove the table had refernce key then, you must
  need to remove this table with the foreign key is referenced.

  or

  SQL > drop table EMPLOYEE CASCADE CONSTRAINTS;
  Deleted table.

  This will remove the table parent without droping the child table.

• You would design Tables without primary key?

  If you were asked to design a schema, if you create a table (however irrelevant) without a primary key? For example, a 'unprofessional' table such as a logging of errors table that records exceptions thrown from stored procedures, create you this table without a primary key?

  In a relational database you define und work with entities (tables) and you put in relationship to each other by joins. An entity must by definition always be identified by a unique key.
  If you don't know what kind of unique key identifies your entries in the table, it is almost certain that working from home in your datamodel and table designs had not been made. Your database objects contain tables, and they must have a unique identifier. Often it is a primary key (PK) composed of several columns.

  By definition a datamodel that contains the tables without primary keys is nomore a relational datamodel and one of the fundamental bases for the creation of a relational database is violated.

  Frankly I do not understand why Oracle allows the tables without primary key. Another system such as SAP R/3 are more stringent. Primary keys are required in the SAP and believe, when starting, it is sometimes tedious to define the primary key structures, but it's the basis of designing together relational datamodel you will put in place. You now SAP is based often on a DB ORACLE layer. They could do it, and these "extend" their functionality. But they are smart guys in Walldorf, and they always refrained to do. It's a good guess to believe, they have a good reason for it.

  Tables without primary key are NO relational tables, they are dungpiles. As Oracle needs priimary key itself in order to operate a relational database, ROWID have been defined. ROWID is the primary keys of the tables where the customer does not have a PK. But nice as ORACLE is, they strongly recommend not to use these ROWID in the application or database layer. ROWID is no identifier object that are stable in time and space (eg. two different databases in a distributed design oder a DEV and PROD-system).

  Definition of PK implies certain rules for the programming of your application and your DML operations. Especially you often MERGE in a relational table instead of simply INSERT'ing piece in a dungpile.

  When it later on with SELECT large datavolumes dataaccess, again the differences between well-defined joins (all based on the PK-relations) and joins non-unique keys will be the order of magnitude. Not only that, the latest degrades in performance much more quickly with the growth of result sets. When you start fumbling with no UNIQUE INDEXES, speed up performance in the operations of dungpiling you are already closer to hell than on a sunny day in the world of relational data.

• Primary key for the Table is

  Hello guys,.
  
  I have a question about the primary key in my fact table. In my fact table, the primary key is a combination of 3 different columns, 2 columns are primary keys in dimension tables 2 diff. Is it normal to have a primary key in a table of facts, which is a combination of 3 different columns. If yes then when us will be important to the OBI tool only 3 columns Phy layer appears as the PK. should I do the other 2 columns as the PK in the physical layer of the OBI tool or can I leave it as it is. Please let me know
  
  Thank you.

  I did as you asked me to. Can you let me also know what will happen if I do only a single key as PK and let them other 2 touch as it is. This will affect performance in > is it possible or will I get incorrect values?

  No, this will not affect anything, in any case explicitly will give you joined him again in the physical layer.
  But it is advisable to show the key columns in the physical layer of the RPD.

• data transfer from one table to another and by generating a primary key

  Hello experts,
  
  Well, I have 2 paintings and I need to move columns in one of them.
  the problem is state that the primary key of the second table has to go in a column in the first table, and I generate a primary key in the first table as well. How to generate the primary key

  You can insert the value of key primary agent_id from agent table via before level trigger for insertion line. The agent_id value can be generated through a sequence.

  the trigger code can be as

  create sequence seq_agent;
  
  create or replace trigger trg_agent_id before insert
  on agent
  for each row
  declare
     v_agent_id number;
  Begin
     select seq_agent.nextval into v_agent_id from dual;
     :new.agent_id:= v_agent_id;
  End;
  

  So when will pull you insert tasks than this agent_id value will be added. And you will not get error
