• Code to get the data in the child table in composite SOA using the IOM APIs

  Hi all
  
  I am a new bie to IOM. I have a query related to obtaining data in the child table using the API of the IOM in the task of embeded java SOA composite.
  
  I've created a workflow that has a form of child of providing service of slef. I created a composite SOA custom also approval. In the composite approval I have embedded java code and I want to get the values entered in the child form using the API IOM inot the java code embeded in composite SOA.
  
  I tried gettting the child form data by using getChildAttributes(), but I'm getting the following exception.
  
  The local Exception stack:

  Please suggest me if I'm following the correct procedure of the child form data or if we can use another approach.
  
  Can we get the data using formInstanceOperationsIntf.getProcessFormChildData ().
  
  Thanks in advance for the help.
  
  Thank you
  PT

  When you're in approvals, there is no form of process data. Process form data would come only when approvals are completed. If you want to read data from the child form of the DataSet (i.e. the form object as in OIM9.x) you can use the RequestService on the id of the request and read the data. Or another approach would be to the child the dataset data value in the payload of the request and read the XML payload in the composite.
  Let me know if you need more information about the second approach. As for the first approach, search through the forums here and you should find my previous posting on how to reach child dataset values using the ask service API.

• How to load the child table by using a simple slider...?

  How can I loa the child table by using a PL/SQL block cursor...
  
  for example, I have a table of the source called method
  
  EmpNo, empname, deptid deptname
  
  and I have 2 tables of taget... EMP and Dept.
  
  EMP
  ===
  EmpNo, empname, deptid
  
  Dept
  ====
  deptID, deptname
  
  
  Here, I want to load method for emp data and... Dept where dept does not contain data in double...
  
  For now... I used the cursor and in the same cursor, I'm loading data first dept table and then to the emp table.
  I use for dept, exceptional setting, which will manage a PK constraint violation error by doing nothing...
  
  in this way, there will be no duplicates... but it is not advisable because I 15,00,000 lines in the method table.
  
  Is there another way to do it?

  OK, I'd probably go with the method two insert, but as an alternative, here's a way to do it in a single insert:

  create table emp_info as
  select 1 empno, 'a' empname, 101 deptid, 'aaa' deptname from dual union all
  select 2, 'b' empname, 201 deptid, 'bbb' deptname from dual union all
  select 3, 'c' empname, 101 deptid, 'aaa' deptname from dual union all
  select 4, 'd' empname, 101 deptid, 'aaa' deptname from dual union all
  select 5, 'e' empname, 301 deptid, 'ccc' deptname from dual;
  
  create table emp (empno number primary key, empname varchar2(3), deptid number);
  
  create table dept (deptid number primary key, deptname varchar2(3));
  
  insert all
    WHEN rn = 1 THEN
         into dept (deptid, deptname)
         values (deptid, deptname)
    WHEN rn > 0 THEN
         into emp (empno, empname, deptid)
         values (empno, empname, deptid)
  select empno, empname, deptid, deptname, rn
  from   (select empno,
                 empname,
                 deptid,
                 deptname,
                 row_number() over (partition by deptid order by empno) rn
          from   emp_info);
  
    8 rows inserted
  
  commit;
  
  select * from emp;
  
       EMPNO EMP     DEPTID
  ---------- --- ----------
           1 a          101
           3 c          101
           4 d          101
           2 b          201
           5 e          301
  
  select * from dept;
  
      DEPTID DEP
  ---------- ---
         101 aaa
         201 bbb
         301 ccc
  

  You must test these two methods to see which is more efficient.

• Records in the Child Table to return DBAT connector deletion and addition

  I'm trying to add a record of the child to a resource DBAT (11.1.1.5). The structure of the Table is set up like this:

  OIM_USR

  Usr_key	First name	Last_name

  OIM_ROLE

  USR_KEY	ROLE_KEY

  Where OIM_USR is the parent, and OIM_ROLE is the child that can store multiple values per user.  The problem arises when there is already an existing value in the child table. Consider the following example for instance

  OIM_USR

  Usr_key	First name	Last_name
  45	John	DOE

  OIM_ROLE

  USR_KEY	ROLE_KEY
  45	2454
  45	4453

  If I add another line to the role of the identity UI table Edit tab added resource role, but IOM is remove the previous two lines and then adding them back. We know that it is because the source OIM_ROLE table contains a timestamp of creation triggered update time when a row is added. If I add a line to OIM_ROW then all three are getting updates for a reason any. We can also see the history of resource shows three updates. Inserting a record of the child should not call the process of update tasks. I've attached a screenshot of the history of the resource.

  In addition, I upped the DBAT Connector logs and he showed a trace of remove:

  DELETE FROM OIM_ROLES WHERE OIM_ROLES. USR_KEY =?

  Why he deletes all children lines before an insertion?

  I think you use OOTB DBAT connector without modification. I think that's how its design to add/change/delete files. For child process also updated form, we follow the same approach.

  Are you facing any functional problem in connector DBAT to reach your use cases?

• IOM 11 GR 2 - Entilements are removed if the child tables are not met.

  Hello experts,

  I use the OOTB DBUM connector.

  When a user has certain rights assigned to IOM (db, db roles privileges) need to be addressed in the child tables before any account update otherwise they are deleted/revoked.

  In other words when the update of a parent account attribute, I need also to populate child tables with payments already assigned, so I leave them blank, all payments will be deleted: empty child tables means "remove all rights", instead, I don't want to change the right assignments.

  How can I do this?

  Fixed by the creation and use of a new form of resources.

• 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.

• How to find the child tables

  Hello
  
  y at - it (quesry) way to find the list of children tables for a given table.
  
  tried to interview user_constraints and USER_CONS_COLUMNS, but not be able to find a way.
  
  Thank you

  Hello

  You can use the query as follows - it will list the children tables and the FK name for table HR.JOBS:
  Select
  a.Owner, a.table_name, a.constraint_name
  sys.all_constraints a.,
  (select master, constraint_name from sys.all_constraints where owner = * 'HR' * and table_name = * "JOBS" * and constraint_type in ('P', 'U')) b
  where
  a.CONSTRAINT_TYPE = 'R' and a.r_constraint_name = b.constraint_name and a.r_owner = b.owner

  If you do not need name FK, then put separate:
  Select
  a.owner, separate a.table_name
  sys.all_constraints a.,
  (select master, constraint_name from sys.all_constraints where owner = 'HR' and table_name = 'JOBS' and constraint_type in ('P', 'U')) b
  where
  a.CONSTRAINT_TYPE = 'R' and a.r_constraint_name = b.constraint_name and a.r_owner = b.owner

• Insert correctly last record to the child table in the multi user environment.

  Hello
  I have the following situation.
  
  Two Tables
  Table1 has a primary key named ID column
  Tabel2 contains a column named table1_id, this is a foreign key to table1.
  
  I have a tabular report that contains an add record button and a button submit to table1. (this table has other columns that require attribution)
  
  I want to insert a record into table2 automatically whenever the user presses submit.
  
  I have a query like this to get the last record in table1:
  

  SELECT MAX(id) 
    FROM table1

  and I would use it in a submit after procedure like this:
  

  DECLARE v_id NUMBER;
  
  BEGIN
  
      SELECT MAX(id)
        INTO v_id
        FROM table1
  
      INSERT
        INTO table2(table1_id)
      VALUES (v_id);
  
  END;

  The thing that worries me, is that the application that I use is a multi user environment. I'm afraid that if two or more people use as MAX recording is not the right one.
  It's a legitimate concern?
  If so, is there a best way to do this kind of thing.

  Ben:

  The triggers are usually avoidable IMO. But, there is always a but, you already use triggers elsewhere in your application, and probably your form the apex uses the routines of APEX MRU for DML and thus leaves the trigger as the only viable option to achieve what you're trying to do.

• 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);
