Master detail form can not insert foreign key

Hello

I Master detail form, in the data block master, I Header_ID primary key and it is generated through trigger on the main table and this field is found in the data block but is hidden on the Web, this Header_ID is a key in another table, on the form, I created the main form and has also created the good relationship. now, when the new record is inserted, the Header_ID in the main table is filled properly while in the secondary table that goes with the NULL value. I have no idea how to solve this problem, any help will be appreciated

Rather than use a database trigger, select INSERT before triggering in the basic data block to fill the HEADER_ID.

In the before INSERT trigger, you'd have a line like:

select seq.nextval into :MASTER.HEADER_ID from dual;

When you do this in the before INSERT trigger will fill the element in the block MASTER that feeds in turn the question into the DETAILS or blocks.

  • I have some problems with a ONE_TO_MANY relationship, can not insert the record

    I have some problems with a ONE_TO_MANY relationship:

    Imagine the following entities:

    -J' have an operational entity with a relationship to workers one_to_many something like:
    @SecondaryKey(relate = Relationship.ONE_TO_MANY,
        relatedEntity = Worker.class)
        private Set<String> workers;
    -The category of workers is a simple annotated entity.


    Now, I want to do the following and I get the error:

    -Create a bunch of tasks
    -Insert tasks into the entitystore
    -create a set containing all the tasks of primary key
    -involve workers to tasks
    -Insert the task in the database


    The above procedure works fine, but when I try to associate the same set of workers with another task I get an exception like:
    com.sleepycat.je.DatabaseException: (JE 3.3.75) Could not insert secondary key in persist#Sample#sample.Task#workers OperationStatus.KEYEXIST

    Can someone please clarify what my problem is and where I should change for this case study work?

    Thank you

    The above procedure works fine, but when I try to associate the same set of workers with another task I get an exception like:

    The table in this javadoc should help. Please think about whether they are 1 of many, many 1 or many is the appropriate link.

  • How to determine the ROWNUM in a Master detail form

    Hello

    I work in a master detail form with controls and information in order of points; I have created a process that allows users to select a product on a tabular presentation ID and the next column is filled automatically with the Product Description.

    To achieve this, I followed some instructions by Denes Kubicek (http://apex.oracle.com/pls/otn/f?p=31517:241), but my case is slightly different:

    < ul > I use a form tabular-created by Wizard, instead of manual tabular form; and < /ul >
    < ul > instead of using another page as a Popup to pass the parameter of the ROWNUM, I use a plugin called "tabular form Super LOV" which is a modified version of Super LOV the SkillBuilders who works on tabular forms. < /ul >

    The product ID is returned in the line by the plug-in; but in the case of the Description of the product, it is always returned in the first row; and my problem is that I don't know how to determine the line where the user clicked to call the plugin.

    I created an example in apex.oracle.com in case someone wants to look at:
    Workspace: ediazjorge
    User name: test
    Password: test
    App name: Sample App
    The app number: 1550

    BTW, I use Apex 4.1.1.00.23 and Oracle DB 10.3.2.

    Thanks in advance,

    Erick

    See what {message identifier: = 10436048}

    OR

    {message: id = 10458307}

    You must use something like below

    //in your case currIndex means the ROWNUM value you have
    $('input[name="f03"]')[currIndex].val('some thing')
    

    And for the jquery selector try this

    $('img[alt="Popup Lov"]')
    
  • Run insert data of time to master detail form

    When I click on the MasterInsert Button and choose the value lov, lov extract data from the database, but

    lov value cannot insert data into the database

    When I click on the Insert button master

    When I choose the value lov, lov extract data from the database

    My requirement is when I select value lov, lov retrieves data from the database when I click on the value of lov masterinsert button may not work as atuosubmit

    Sorry, but you have not answered the questions (and a post should be sufficient to answer three simple questions).

    A class has a name. How should we n´know what the largest number field that we see in the picture is the master lov?

    Why are you trying to use a client/server Listener on the button? If you do not want to display a lov use an inputText or an InputListOfValues.

    If you provide all the information, you can not expect us.

  • Master detail form based on single Table

    Hi all.
    I have a table like

    daily_transaction
    (
    TRANSACTION_DATE DATE,
    LINE_ID NUMBER,
    ITEM_CODE VARCHAR2 (10),
    NUMBER OF BALANCE,
    DESCRIPTION VARCHAR2 (500)
    )

    Now, I want to build form master detail

    master form have only transaction Date all in the form of retail have row id, item, balance, date of transaction, description code

    I join date of the main transaction with the date of the transaction in detail

    now the problem is when I enter two archives in the form and save it, it save 3 record in the table, an empty line except transaction date
    Please guide me how to save two archives:

    Secondly when I update / edit date of master on the date of the operation blank line change, how do I update details form

    In order to perform an update on a view - it must be a "editable view. You try to update the MASTER block (based on the view)? Otherwise, make sure that you change the property update block allowed to 'No' as it is default to 'yes '. If you do not update the MASTER block, make sure that your point of view is "can". Read this article from Tom ask article on editable views. http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:5226026422731.

  • Not getting foreign key fields not filled in datacontrol palette for EJB app

    Hello

    I am quite new FAD and EJB. I developed an application jdeveloper with levels of JSF and EJB. (I use jdeveloper 10.1.3.5)
    For the database to the default human resources database is used. I created the entities for the table EMPLOYEES and DEPARTMENTS.
    I also created a session bean and a data control to the session bean.
    I'm having a JSF page that receives all the details of a new employee and insert into the database (i.e. persistEntity)
    But the constructor used in the data control palette is not filling the MANAGERID and DEPARTMENTID, fields that are
    the foreign key constraints for table and EMPLOYEES by result while trying to make persistent entity
    with automatically filled fields, an error message is thrown.
    If I've used ADF BC instead of the EJB then I could fill all the fields including MANAGERID and DEPARTMENTID.
    Is it possible to have two fields text Manager and Department in the jsf to insert the details of the employee with EJB as a model?.
    If possible how to bind the values of these fields to the entity used in EJB object.


    Kindly need your ideas on this.

    Thank you
    Guna.

    Hello

    How you use MANAGER_ID and department_id fields, they also flush long (or another digital type), or you don't have them mapped to the entity, something like this

    ....
    @ManyToOne
    private Employee manager; // this by default uses the column named MANAGER_ID
    @ManyToOne
    private Department department; // this by default uses the column named DEPARTMENT_ID
    ....
    

    If you have mapped them (which is the right path), when you create an employee, you must set these attributes to the persistence of the entity, using employee.setManager (manager) and employee.setDepartment (department). Then, foreign keys filled automatically by your persistence provider (Toplink).

    If you use data controls, it's a little different process to define the Manager and the Department, but you should take a look at this tutorial http://www.oracle.com/technology/obe/obe11jdev/ps1/ejb/ejb.html, it will answer many of your questions hopefully.

  • master detail forms

    Hi experts,
    Now what I want is that I have two differnet forms in a same canvas and two GEC is referring to the same table. I want that when I'm going to give entry to the first form and after having pressed a button, I'll find the details in the second form.

    The two forms are connected to the same table that is why there is no ship master details of relationship between them.

    can you please suggest something.

    Concerning
    Rajat

    By "form" you mean right blocks?
    Try to make a self-join relationship between the two blocs, but ultimately depends on your data structure, you can and maybe aren't able to use self join, but it is worth the try.

  • can associate US foreign key index?

    Hello
    I've searched and can't find the answer to the foregoing;
    I have a foreign key table constraint; I added an index on that column
    However when I ask the all_constraints under index_name to this foreign constraint, there is nothing. only when I PK/UK I deal see index associated with them;
    then oracle will still associate my index finger with the FK column forced? or I need excplicity pair with the foreign key column? If so, how?
    THX
    Rgds

    When you do "I added an index on that column;" you "associate explicitly" a column with an index.
    You can check this with

    select *
    from all_ind_columns
    

    But there is no direct relationship between a FK constraint and index

  • Join sorted on 2 tables, not a foreign key

    Hello

    I have two tables:

    BookAuthor
    -------------
    number surrogateid
    AuthorName varchar
    number bookid

    Books
    -------------------
    number bookid
    BookTitle varchar
    other columns

    I want to make some kind of query to join on the two tables where the query arguments are: rangefirst and: rangelast for 2 authornames, where I want to catch all bookauthors authorname between implicit, sorted, and then join the table books to fetch the booktitle and bookid and the authorname, and authornames which are the same also sort the product join by booktitle to the Books table.

    I hope it's possible!

    NOTE: there no foreign key relationship, so if a line of BookAuthor bookid value that does not exist in the table of books, I don't want a line into the product.

    And what kind of evidence do I need on each table.

    Thank you
    Andy

    You need clues if your table is large enough and you select only a few records in the table.

    If the create index case bookid on tables.

    Once the data are joined, you have no clue to the order.
