  Yes... but then, someone is bound to point out that views can be materialized in persistent data objects. ++*

• How the identity if one table used only by synonyms and not by any other subprogrammes in a schema?

  Hi people

  How the identity if one table used only by synonyms and not by any other subprogrammes within a schema. I see in the TOAD describe objects tab used by, but I would like to identify hundreds of table so I would like to know if there would be any SQL or Meta Data Tables?

  The ALL_DEPENDENCIES view has hierarchical information based on object_id

  The view object has the object_type.

  Create a hierarchical query on the first view and attach it to the second view.

  Or you can use the utldtree.sql file in the installation of the DB admin folder. Comments initially show you how a hierarchical query based on the object type.

• Add FK between a table and a view?

  Is this possible in 4.1 to add a FK between a table and a view (off of course)?

  If I'm in a view, it seems that I can define a FK to another view or a table, but if I start with a table, some views appear in the list. The view already has a defined PK.

  Is it normal?

  Use case: I have a table of generic code, so I'm set up views on the code for each type of code table. Then, I want at least diagram CF from specific code view of the code typed column on a table for the sub.

  Hello Kent,

  Is this possible in 4.1 to add a FK between a table and a view (off of course)?

  Yes.  You can do this by clicking on the icon of the new foreign key above the diagram, then by selecting the view first, then the table.

  I connected an enhancement request to allow a foreign key to a view to be added using the table properties dialog box.

  Thanks for pointing it.

• Difference between the table and Materialized View

  Is there an advantage outside automatic synchronization (founded refresh selected type) using Materialized View?

  I came across this question as table and MV both store values, and we can also update table using the code what is the need of MV? Why not create a table instead of MV with the same definition and same charly?

  I need some explanation to force someone to convince himself.

  Thank you

  I explored a similar approach, using the following test case.

  It creates a table "MASTER_TABLE" containing 20,000 lines and a CLOB containing an XML fragment like this:

• Functions Pipeline Table with other tables using

  I'm on DB 11.2.0.2 and used sparingly in pipeline table functions, but plans to arrays for a project that has a pretty big (many lines). In my tests, selecting from the table in pipeline perform well enough (if it's directly from the table pipleined or the view from above, I have created). Where I start to see some degregation when I try to join the tabe in pipeline discovered at other tables and add where conditions.

  SELECT A.empno, A.empname, A.job, B.sal

  OF EMP_VIEW A, B OF THE EMP

  WHERE A.empno = B.empno AND

  B.Mgr = '7839'

  I've seen articles and blogs that mention this as a matter of cardinality and offer some undocumented methods to try to fight.

  Can someone please give me some tips or tricks on this. Thank you!

  I created a simple example using the emp table below to help illustrate what I'm doing.

  DROP TYPE EMP_TYPE;

  DROP TYPE EMP_SEQ;

  CREATE OR REPLACE TYPE EMP_SEQ AS OBJECT

  (EMPNO NUMBER (10),)

  The ability to join would give me the most flexibility.

  Pipelines can be attached. But here is the PL/SQL code - no tables. And without index.

  Consider a view:

  create or replace view sales_personel in select * from emp where job_type = 'SALES '.

  And you use the view to determine the sellers in department 123:

  Select * from sales_personel where dept_id = 123

  Oracle considers that logically the next SQL statement like her can be pushed in the view:

  select * from emp where job_type = 'SALES' and dept_id = 123

  
  

  If the two columns in the filter are indexed for example, he may well decide to use a fusion of index to determine what EMP lines are dirty and department 123.

  Now consider the same exact scenario with a pipeline. The internal process of pipelines are opaque to the SQL engine. He can't say the internal code pipeline "Hey, don't give me employees service 123".

  He needs to run the pipeline. It must evaluate each channeled line and apply the "dept_id = 123" predicate. In essence, you must treat the complete pipeline as a table scan. And a slow that it take more than a simple disc lines when you perform the transformation of data too.

  So yes - you can use the predicates on the pipelines, can join them, use analytical SQL and so immediately - but expect it to behave like a table in terms of optimization of SQL/CBO, is not realistic. And pointing to a somewhat flawed understanding of what a pipeline is and how it should be designed and used.

• Update of a Base Table in a view with a UNPIVOT function.

  Hello
  I have a requirement to upgrade a Base Table in a view.
  This view has the query by using a function of the UNPIVOT operator to display the columns in the tables of the basic of the lines.
  I need to update/insert in / remove the Base Table by accessing the view (the user has access to the Base Table, so the DML on the view).
  
  Here is the table I created:-
  

  CREATE TABLE PERSON_DETAILS
  (
    PID            VARCHAR2(10 BYTE),
    FIRSTNAME      VARCHAR2(1000 BYTE),
    LASTNAME       VARCHAR2(1000 BYTE),
    PHONENUMBER    VARCHAR2(1000 BYTE),
    ADDRESS1       VARCHAR2(1000 BYTE),
    ADDRESS2       VARCHAR2(1000 BYTE),
    COUNTRY_CODE   VARCHAR2(1000 BYTE),
    LANGUAGE_CODE  VARCHAR2(1000 BYTE),
    EMAIL          VARCHAR2(1000 BYTE)
  )

  The sample values are inserted in this table using the script below: -.
  

  insert into person_details values ('1','XYZ','ABC','1234567890','India','Asia','IN','EN','[email protected]');
  insert into person_details values ('2','XYZ2','ABC2','1234567890','India','Asia','IN','EN','[email protected]');

  The code for the display is as below: -.
  

  CREATE OR REPLACE FORCE VIEW PERSON_DETAILS_VIEW
  (
     PID,
     CD_NAME,
     CD_VALUE
  )
  AS
     SELECT "PID", "CD_NAME", "CD_VALUE"
       FROM person_details UNPIVOT INCLUDE NULLS (cd_value
                           FOR cd_name
                           IN  (firstname AS 'First Name',
                               lastname AS 'Last Name',
                               phonenumber AS 'Phonenumber',
                               address1 AS 'address1',
                               address2 AS 'address2',
                               country_code AS 'Country Code',
                               language_code AS 'Language Code',
                               email AS 'Email') );

  Here are the values of the view:-
  

  PID CD_NAME         CD_VALUE
  1    First Name       XYZ
  1    Last Name       ABC
  1    Phonenumber  1234567890 
  1    address1         India
  1    address2         Asia
  1    Country Code   IN
  1    Language Code EN
  1    Email               [email protected]
  2    First Name       XYZ2
  2    Last Name       ABC2
  2    Phonenumber  1234567890
  2    address1         India
  2    address2         Asia  
  2    Country Code   IN
  2    Language Code EN
  2    Email               [email protected]

  The user would fire any statement as below: -.
  

  update person_details_view 
  set cd_value = 'US' where CD_NAME = 'IN'

  The statement above should update the PERSON_DETAILS database table.
  
  I understand that I can write an INSTEAD OF trigger, but I don't know what logic to write in the trigger so that the condition is met.

  It is definitely possible with an INSTEAD of trigger.

  for example:

  create or replace

                        FROM   
  
                            (
                                select * from person_details_view where (pid, cd_name) not in (select :new.pid, :new.cd_name from dual)
                                union all
                                select :new.pid, :new.cd_name, :new.cd_value from dual
                            )
  
                        )
                PIVOT  ( max(cd_value) AS new FOR (cd_name) IN
                                                        ('First Name' AS firstname,
                                                          'Last Name' as lastname,
                                                          'Phonenumber' as phonenumber,
                                                          'address1' as address1,
                                                          'address2' AS address2,
                                                          'Country Code' as country_code,
                                                          'Language Code' as language_code,
                                                          'Email' as email
                                                          )
                )  where pid = :old.pid;
  
    UPDATE person_details
    SET firstname = firstname1
    WHERE pid = :old.pid;
  END ioft_role_perm;
  

  and that run

  update person_details_view
  set cd_value = 'X|X' where cd_name = 'First Name' and pid=1
  

  The logic is: you need to convert back the view through swivel

• creating a view and use the view in a model

  Hi all
  
  I'm new to OBIEE, and I have a requirement that I have two fields to be added to a domain. Because we cannot add queries directly to a model, I have to create a view and then put the request in it, and then use the view in this model.
  I did not understand this well, if someone could help me, explaining in detail the view and adding a query in it?
  
  Thank you
  Gohan

  Hello

  (a) If you want to use your existing DB view please tick box import meta option data - RPD--> file menu
  (b) If you want to create the new view in RPD itself just right click anyof a physical table--> properties--> click the genral--> change the type of array as "Select" then you create/update your sql query, and then click ok that's all
  Once created, you can deploy advice on the database (right mouse button) or you can leave the view cancelled (worst performance).

• The use of view to create a list of values?

  Hi, I try to use the view to create LOV, but I do not know name of the Table/view drop-down list, how do I find the list of reviews?
  
  Thanks in advance,

  Karman,

  You can type directly, on behalf of the view instead of going through the search list. If you do not know the name of the view, you can open the SQL workshop in a new window or tab.

• How to find objects (tables) used in MS

  Is there any query with which I find all the tables that are used (to perform the operation Select Insert Update Delete) in a procedure in oracle 10g.
  
  I want to take on all the tables used in particular. but it is more difficult to find by looking at the line by line as the sp is 3 k + lines.

  View USER_DEPENDENCIES:

• Retrieval of a list of objects of entity without using a view

  This is probably a really basic question, but I did have to do something like this for the moment. I mainly worked on my user interface so far and have used views exclusively. Now, I just want to back work that gets EO of the database, iterate through the evaluation office, one by one.
  
  Let's say I have an entity object named "Subscription" which is mapped to my "Subscription" using ADF BC (MySQL) database table.
  
  How can I get a list of populated, subscription objects that I can go, instead of having to use a view object?

  Of course

  Take a look at the code example [url http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcquerying.htm#CHDECJHD] in the documentation - Yes, the code has a few extra things in there you don't need (such as the definition of the place where clause), but you have an idea how to create a module of the app and get an instance of original Version of it.

• How to insert a new record or update existing record by using a view complex?

  Currently, I created this screen, there is no problem on display data, on the update feature (average TI insert / update / delete on the table for which the view is based on).
  
  I have a table and a view complex in order to display the information in the table in a form of tabellar (IE up to 70 record in same "record" in the form, one for each article)
  
  The view is like this
  
  
  
  Select a.f1, a.f2, get_value(a.pk1,1) a1, a2 get_value(a.pk1,2), get_value(a.pk1,3) a3...
  
  from my_table a
  
  where a.proj_id = user
  
  
  
  
  
  and I want to allow the update of the field a1, a2, a3 in a multiplace (tabellar) canvas.
  
  I created a TRIGGER INSTEAD.
  
  But it works not only in the form. I get FRM-40654 error when I try to change the existing value in the form running based on this point of view.
  
  The view is woking and editable using sql-plus.
  
  If I have question
  Select * from ALL_UPDATABLE_COLUMNS where table_name = 'SPV_BOQ_BOM_POS_ACTIVITIES ';
  
  where "SPV_BOQ_BOM_POS_ACTIVITIES" is the name of my point of view.
  
  The question is: why if the view is updatable using SQL * Plus, is not editable using the Oracle 10 g 2 form?
  
  Could someone help me ASAP?
  
  Thank you

  Forms to lock the record when you start editing. It is is by a statement of the type

  SELECT 
    FROM 
   WHERE =
     FOR UPDATE NOWAIT;
  

  If this attempt fails, the error you are getting is displayed. As solution to create a trigger-LOCK-ON on the block and with which replace standard logic.
