• ADF Parent-child tables of rules

  Hello

  I use JDeveloper and ADF 12.1.3. Now, I have a set of related tables, and each of them have only a child table.

  I have a jsf page master / detail for each child table. Inside it, I can insert a row in the parent table and several rows in the child table. Commit the button is clicked validate monkey for the booth tables. Link between the master (parent table) and retail (child table) is done via the partnership link and view for the user interface.

  Now, here's the rule I would apply: I can't commit newly created at the table parent without at least a new inserted row in child table.

  Because I have several parent-child tables in this case of use, I wanted to replace the EntityImpl class and add newly created to each parent table class, so I bussines logic in one place for this tables.

  We will look and taste to the table of one of the parents (not overloaded class EntityImpl):

  The Interior has generated parent EO class

  @Override

  {} public void beforeCommit (TransactionEvent transactionEvent)

  TODO implement this method

  If (! validateParentChildNumber()) {}

  throw new local ("not allowed.");

  }

  super.beforeCommit (transactionEvent);

  }

  public boolean validateParentChildNumber() {}

  If (getParentChild (). GetRowCount() > 0)

  Returns true;

  on the other

  Returns false;

  }

  This works well. If I inserts a row in the parent table and one or more rows in the child table passes validation. But if I get a line inside the parent table and no line of children tables I'm not allowed message in my browser.

  So here's where problem read. Once I'm getting now authorized message, no matter if I insert the new line of Herald, I cannot commit until what I restar my app. Why? Because now, I constantly have this message:

  ORA-02291: integrity constraint (RE. FK_PAR_PAR_ID) violated - key parent not found

  It's like I can't hire the existing parent row I inserted before the child missing line. Why is this happening? I should replace postChanges method and what to put in it?

  Thx a lot

  Yes, you should do it in all cases, but point of my post is - put this code in the method of beforeCommit() of the primary entity. Only you need to do in beforeCommit(), is to count the child related entities.

  In your java master entity impl class, you will have the method which returns a RowIterator with associated children, entities, something like that

  public getChildsEO() {} RowIterator

  return (RowIterator)...;

  }

  then, just call this method in beforeCommit() and see if there is at least a child entity...

  You have a point?

• Blockages with parent/child tables

  Guys,

  We have a parent-child of tables in our database with the DDL below:

  CREATE TABLE 'ACCOUNT '.

  (SELECT 'ACCOUNT_ID' VARCHAR2 (32 BYTE) NOT NULL,)

  X, Y, Z,...),

  'XPK_ACCOUNT' CONSTRAINT PRIMARY KEY ('ACCOUNT_ID');

  CREATE TABLE ACCOUNT_PARTITION ".

  (SELECT 'ACCOUNT_ID' VARCHAR2 (32 BYTE) ENABLE NOT NULL, "BALANCE" NUMBER (5.0) NOT NULL,)

  X, Y, Z,...),

  'XPK_ACCOUNT_PARTITION' CONSTRAINT PRIMARY KEY ('ID_COMPTE', 'BALANCE')

  KEY FOREIGN CONSTRAINT 'ACCOUNT_PARTITION_FK1' ('ACCOUNT_ID')

  SELECT THE 'ACCOUNT' ('ACCOUNT_ID') REFERENCES);

  "Lately, we cross " ""ORA-00060: Deadlock detected while you wait for resources ' errors while DELETING in the tables above. Please note that the tables of the child is not any clue except KP index.

  
  

  Could someone please suggest resolution for us to minimize the error of blocking?

  
  

  Respect,

  Bugs

  Imagine you remove account, Oracle must verify there is no record of the child in ACCOUNT_PARTITION, this is because as your FK is restrict the deletions (do not allow the removal if there are child records).  As ACCOUNT_PARTITION. Account_id is indexed so it will be an exclusive table lock to find this, locks the table.

  Another way of thinking is, imagine that you have performed the following query without and ACCOUNT_ID index:

  Select *.

  of ACCOUNT_PARTITION

  where ACCOUNT_ID =

  He SHOULD do a full table scan right?  Well well, even on a deletion of the parent. It attempts to identify lines for the purpose of blocking,

  As a general rule, it is always a good idea to index FKs.

• Update the data to uppercase in the parent/child tables

  Hi gurus!
  
  In production, we have a table product and that is in reference by many tables making parent child relationship. By mistake, we realized last month some products have been added to lowercase and now we have a request to update all these product codes uppercase so that existing code that use these tables have no impact. Appreciate if you can give an idea about how can I update the existing data in the table parent uppercase as well as child records?
  
  Concerning
  Sri

  Are the product code that you need to update what is stored in the tables of children? If Yes, then you must do it in several steps, something like:

  Identify the child tables

  SELECT table_name, constraint_name
  FROM user_constraints
  WHERE r_constraint_name = (SELECT constraint_name
                             FROM user_constraints
                             WHERE table_name = 'PRODUCT_TABLE' and
                                   constraint_type = 'P');
  

  Create new product of upper-case code in the product table:

  INSERT INTO product_table
  SELECT UPPER(product_code), other_columns
  FROM product_table
  WHERE product_code <> UPPER(product_code);
  

  Update the children tables for caps product codes

  UPDATE child1
  SET product_code = UPPER(product_code)
  WHERE product_code <> UPPER(product_code);
  

  Finally, remove the tiny product_table product codes

  DELETE FROM product_table
  WHERE product_code <> UPPER(product_code);

• Parent - child Tables (query to sum up)

  Hello people:

  Hope you're all well today.  Here is my sample data:

  WITH the fleet (fl_id, veh_id)

  (

  SELECT 95, "T02" dual UNION ALL

  SELECT 105, "T22" OF THE double

  ),

  fleet_keys (id_pk, fl_id_fk, key_number) AS

  (

  SELECT 294, 95, 'ADB185' FROM dual UNION ALL

  SELECT 295, 95, 'ADB186' FROM dual UNION ALL

  SELECT 296, 95, 'ADB187' FROM dual UNION ALL

  SELECT 297, 105, 'BCB205' FROM dual UNION ALL

  SELECT 298, 105, 'BCB206' FROM dual UNION ALL

  )

  SELECT fl.veh_id, flk.key_number FROM floating fl

  LEFT JOIN fleet_keys ON fl.fl_id = flk.fl_id_fk flk

  This simple query with a left join on the primary key to foreign key produces the following data set:

  VEH_ID	KEY_NUMBER
  T02
  	ADB185
  	ADB186
  	ADB187
  T22
  	BCB205
  	BCB206
  	BCB207

  Is there an easy way to do this?  Thanks for your help.

• Parent - child Table Insert Trigger

  Hello
  I need assistance with an Insert trigger. I want to insert field data 'Table A' "Table B" based on a PK and FK. Someone at - it examples of code?
  < code >
  Table A
  SEQ_NO - PK
  TO FIELD
  FIELD B
  C FIELD
  
  Table B
  FK_SEQ_NO
  FIELD B
  C FIELD
  < code >
  
  When the data is stored in the 'table A' I need fill out the 'FK_SEQ_NO', based on the saved value 'Table A' "SEQ_NO" as well as the values of FIELD B and C FIELD recorded in Table B.
  Any help is really appreciated, thank you.

  Hi Charles,

  It depends exactly how you created your trigger.

  In my trigger I fill WORK_PACKAGE_ID (PK) in the parent table using rmdb_work_packages_seq. NEXTVAL. The insert statement then uses: NEW. WORK_PACKAGE_ID to fill the coumn FK in table child.

  You can also use ITEM_ID_SEQ. CURRVAL who will repeat the last number that was created, and I suppose that you use to fill A table.

  Hope that helps,
  Martin

• Why Developer SQL displays arrows (relations) between parent and child tables in my entity relationship diagram?

  Hello

  
  

  Oracle version:                     Oracle Database 11 g Release 11.1.0.7.0 - 64 bit Production

  The version of SQL Developer: 4.0.2.15 - 15.21 build

  I have a question about drawing diagram, entity-relationship with SQL Developer & I would be grateful if you could kindly give me a helping hand.

  I would like to draw an entity-relationship diagram in order to better visualize the relationship between multiple tables. After a google search, I found the following interesting article indicating the procedure to be followed:

  http://www.Oracle.com/technetwork/issue-archive/2014/14-may/o34sqldev-2193423.html

  (What I need and I'm trying to produce is Figure 4 in the article above)

  I made exactly as stated in the article & apparently everything has worked well enough, in other words, I had several UML as rectangles showing columns of tables, their data types, primary and
  foreign key and the arrows indicating the link between each parent/child table.

  Later, I tried to do the same thing on a different oracle instance and a different database by using the same procedure. Yet, something strange happened this time. Developer SQL printed on-screen tables, once again,.
  inside the rectangles with types, keys,... but, there was no arrow showing the link between the tables, I just saw on the grid the selected tables but without any association/relationship shown (as a symbol of an arrow)
  between them.

  I repeated the procedure on another instance of development, with a few test tables that I created with primary and foreign keys just to make sure I had followed the procedure correctly. Once again

  the test was successful, but when I repeated the test on another instance, the same problem persisted, in other words, no arrow (relationship) between tables.

  Any idea?

  This could be due to a lack of privilege on the instance? If Yes, what should be granted in what about roles?

  Thanks in advance

  I think that what you see is that not all databases have foreign keys - applications hard-coding relationships vs let the database to handle this.

  Connect to this instance different oracle and browse the tables affected - have FK constraints defined on them?

• I need to stop a download of the query, I thought a stand-alone application but turns require a higher level (FCPX) as a 'parent' and I do not who have, or want to buy.

  I need to stop a download of the query, that I thought a stand-alone application but turns require a higher level (FCPX) as a 'parent' and I do not have that, or I want to buy it.

  Motion IS a stand-alone application. It is mainly designed to make effects for Final Cut Pro X, but it is not necessary to have with FCPX nor is it necessary to have FCPX to create projects for other purposes. When you open the query, simply select project of work outside the FCPX motion. You can save regular projects of Motion anywhere on your system.

• 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:

• BULL, INSERTION IN THE PARENT TABLE AND THE CHILD TABLE

  Hi all
  
  We use bulk insert to improve performance. How to use this concept when I insert the records parent in table parent and child?
  
  example... I have a procedure that accepts the array of student objects
  
  each student object is defined as *(student name, student age, course_object_array) *.
  
  the 3rd element course_object_array is defined as *(coursename,course fee,facultyname) *.
  
  a student can be associated with several courses
  
  Now, I have to insert the data into two tables namely students (studentname, studentage and student_number)
  courses (course_id, coursename, fees, facultlyname, student_number)
  
  I use sequences to fill the columns student_number and course_id.
  
  If I use bulk insert, and insert all the records in the parent table how do I the association for each record of a child. How will I know what child folder must be associated with which of the parents?

  Hi thanks for the reply Solomon.

  I actually know about the bulk collect and for all...

  Have you read that FOR ALL with in fact BULK COLLECT? It will allow you to bulk insert via for ALL with VOTING student_numbers attributed to each student placed in a collection. Then, you will use this collection collection of course list to fill the RACE table.

• Stand-alone table in the repository

  Hello world!!
  
  I'm creating a repository with Administration Oracle BI tool. I have a problem with a table which does not join another repository, the description of the error is:
  
  "15013 logical table, xxx.yyy, do not adhere to any other logical table.
  
  Why is not possible to have a stand-alone table in a repository?
  
  Thanks in advance!
  Jorge.

  You must have at least one other table attached to it... Since it is the '' possible more little star. '' If you need a stand-alone table, you create an alias of the table in the physical layer, bring together both by their PKey and then you're fine.

• Create a parent child

  in collaboration with JDev12.1.2.

  I have a view object that is based on a query. I then another editable view object from an entity. 2 then have a link with a field view id. The VO being the parent and the VO entity based application shall name a child and having a 0.1 - 1 ratio. How can I display a table with each row in the table parent with a child, even if the child does not yet exist. I don't want to have to go and click a button create/insert for each record in the table.

  I was finally able to get it figured out. I had to get rid of my request based on VO and create 2 entity with an association to the entity objects. I then created a VO using the 2 entities and the Association. Then when I created a table of the VO it displays blank fields for the (child table) that you could call it. Then to commit it inserted records children if I entered what anyone in the fields. I had a problem with them not fixing is not the ID that connected the 2 entities, but I managed to fix that in the file VORowImpl of java.
