Querying Detail Master form

Hai All,
Can anyone suggest me how to get the Find window option based on the Detail block.
Presently I am creating a view based on the required column from the Master and the detail block, creating a find window based on this view, from that I am tracking the header Id and getting the required master detail information.
Is there any othere way to directly query the detail block from the find window and get the Master Detail Relation.
Thanks In Advance........

hello
here is the solution,i hope this might help u.
go to the code of your button and change write the following
go_block('name of your master block');
execute_query(no_validate);
and in the object navigator make the first item in the master
block that it should be displayed in the canvas and it must be a
navigable item too.not a display item.
thank you

  • How to query the master block based on one of the values in detail block

    Hi,
    In version 6i forms, I have a field in data block which is not set as a database item. I am using that field to store a value from detail block. If I want to query the form using that field (which represents one of the values from detail block), how do I do that? Any pointers?
    TIA,

    Do you want to query a master, which contains a specific detail? If so, here's an example how you could do it with a PRE-QUERY-trigger:
    DECLARE
      vcQuery VARCHAR2(4000);
    BEGIN
      IF :MASTERBLOCK.THE_DETAIL_SEARCH_ITEM IS NOT NULL THEN
        -- Build up an exists Sub-Query
        vcQuery:=' MASTERBLOCKID IN (SELECT FK_TO_MASTERBLOCK FROM DETAILTABLE WHERE DETAIL_COLUMN=''' || :MASTERBLOCK.THE_DETAIL_SEARCH_ITEM|| ''')';
      END IF;
      SET_BLOCK_PROPERTY('MASTERBLOCK', DEFAULT_WHERE, vcQuery);
    END;

  • Restricting Query in master detail situation

    I got two tables and three forms 1)master-detail 2)a selection form based on detial table.
    When we enter data in master form i.e deptno want to open a selection form with restricting query only to those records that is entered in master from.
    I want to know how to restrict data in selection form.Bit confusing,
    Thank You,
    Zubyr

    add a parameter to your detail form, and set the default-where property of your block.
    you can reference parameters directly in the where clause of the block:
    deptno = :parameter.deptno
    call your detailform from the masterform with a paramlist
    declare
    xParamlist paramlist;
    begin
    xParamlist := Get_Parameter_List('PARAMLIST');          
    IF (id_null (xParamList)) THEN
    xParamList := create_parameter_list ('PARAMLIST');
    ELSE
    destroy_parameter_list (xParamList);
    xParamList := create_parameter_list ('PARAMLIST');
    END IF;
    Add_Parameter(xParamlist,'EMPNO',TEXT_PARAMETER, :master.deptno);
    call_form('detailform',NO_HIDE,NO_REPLACE,NO_QUERY_ONLY,xParamList);
    end;

  • ADF Master Detail entry form issue

    Hi All,
    I am new to JDeveloper and I am creating a Master Detail entry form. I have separate buttons to create master records and detail records in Master and Detail sections respectively. After completing data entry in Master portion, when I hit the create button to create a line in detail, it removes data from the last field of master which is a "description" field. I haven't write any custom code yet. How can I fix this?
    Help will be appreciated.
    Thanks,
    CAH

    Hi,
    Thanks for your reply and links to the tutorials.
    I have changed the default binding to CreateInsert from Create. Unlike in the sample application in the links, my form is editable at both the levels. Apart from the clearing out the description field, it clears out the list items I have defined at Detail level when I create second or greater record. It works fine for the first record at Detail level. And as I mentioned, I have not written any custom code anywhere.
    Any clue will be a great help.
    Thanks,
    CAH

  • Master Detail Java Form

    Where can i find any source code of master detail java form without using BC4J?

    Gawish,
    JSP and Applets are kind of exluding the other. If you don't like to use BC4J, you can use all kind of technologies like EJB or POJOs. ADF will work the same for the two technologies when building user interfaces. See otn.oracle.com/products/jdev for tutorials and how-to.

  • Master form detail table delete and save all

    I use jdeveloper 10.1.2 with jheadstart 10.1.2 I have a problem about delete and save in master detail.I create 1 master form ,1 detail table and 1 detail form in jheadstart.I want to delete details when I pressed delete button in master and I want to save all changes when I pressed save button.But delete and save are only work for master.So my detail data cant delete or save.What can I do for this problem?Thank alot.......

    To delete the details when you delete the master, it is easiest to define the foreign key in the database with CASCADE option instead ogf RESTRICTED.
    I cannot reproduce your issue with Save not working. Can you reproduce this using the HR schema?

  • Pagination for Master Form, Detail Table

    Hi,
    I am using JDev11.1.2.1.0
    I am creating a page having master detail relationship (master as a form and detail as a table). On click of First, Prev, Next, Last pagination button of master should change the data and refresh child table data.
    So created a Master VO & Child VO joined with View Link and dragged into page as Master form, Detail table. But during pagination, NEXT works once, then it seems to stop there. LAST works and FIRST & PREVIOUS seem to both go to the first record.
    Can anyone suggest me when I went wrong.

    Yes Frank, its st. forward use case. I tired with master table with detail table works fine but master form with details table behaviors differently.
    Below snippet of code in JSPX page master form detail table as shown below :
    <af:panelFormLayout id="pfl6">
    <af:panelLabelAndMessage label="Name:" id="plam1">

  • Is it possible to create a Master-Master-Detail JClient Form?

    Hi,
    I've been trying to create a Master-Master-Detail JClient Form, where both master-values will be displayed in a seperated drop-down-list.
    First I've tested this with a single Master-Detail (is it correct, that a single drop-down-list, working as master will not work with LoV-Binding!?) - However, the combobox-model must be set to Navigation-Binding...
    After adding another combobox (the second master), and testing the result, it seems that the detail-table only corresponds to the selection of the first master.
    The problem with LoV-Binding was, that the drop-down-list starts with the value at ID '0' (which doesn't exists) instead of '1'...
    The Question is, how can I create a Master-Master-Detail JClient Form!?
    thanks,
    hubi

    Hi,
    I've been trying to create a Master-Master-Detail JClient Form, where both master-values will be displayed in a seperated drop-down-list.
    First I've tested this with a single Master-Detail (is it correct, that a single drop-down-list, working as master will not work with LoV-Binding!?) - However, the combobox-model must be set to Navigation-Binding...That's true for navigation as you want to use the Combo as the navigator for the Master VO iterator. Lov Binding is used to "update" certain attributes based on selection. You are trying to drive the detail rowset for a selected master and NavigationBinding is the appropriate binding for this purpose.
    After adding another combobox (the second master), and testing the result, it seems that the detail-table only corresponds to the selection of the first master.That's the behavior you get from the default data model.
    The Question is, how can I create a Master-Master-Detail JClient Form!?First you need to create a ViewUsage structure that implements Master-master-detail. This is not allowed by Bc4j wizards. However you can create such a structure at runtime by using createViewLink method on the ApplicationModule to link the "second" master with the detail (same VO as the first Master's detail).
    Assuming both the comboboxes are bound to individual Master VOs using NavigationBinding, you should now be able to traverse the details using both ComboBoxes (which represent the master).

  • Master detail report/form FK problem

    Anyone...anybody!!!
    I'm using APEX 4.0.1... and Oracle 10g.
    I have two tables that are linked with FK in the detail table
    Master table
    ID_ENDURGR     NUMBER --PK populated with a trigger
    KT_UMSAEKJANDI     VARCHAR2(10 BYTE)
    TIMABIL     NUMBER
    NUMER_UMSOKN     NUMBER
    HEILDARKOSTNADUR     NUMBER
    Detail table
    ID_EIGENDUR     NUMBER --PK populated with a trigger
    KENNITALA     VARCHAR2(10 BYTE)
    EIGNARHLUTI     NUMBER
    KOSTNADUR_VINNA     NUMBER
    ENDURGR_ID_FK     NUMBER -- FK on ID_ENDURGR in the master table
    If I create a application with a master detail page using the wizard, pages with a report and a tabular form are created. This works fine and the FK field in the detail table is automatically populated with the PK from the master table.
    If I create an application with a blank page an on that page create a region > form > master detail > same tables >use existing triggers > default > Edit detail on separate page ... three new pages are created: Report, master form and a detail form.
    If I create a new detail record with this application the FK field is not automatically populated.
    Why? What am I doing wrong?
    The trigger on the detail table:
    create or replace
    TRIGGER "bi_RSK_541_EIGENDUR"
    before insert on "RSK_1018_EIGENDUR"
    for each row
    begin
    if :new."ID_EIGENDUR" is null then
    select "RSK_541_EIGENDUR_SEQ".nextval into :new."ID_EIGENDUR" from dual;
    end if;
    end;
    Do I need to add something here... or what?
    Please help.

    Hi,
    Because you're using a composite key with more than 2 columns you'll need to create a view of each table with a ROWID column and use those as your primary keys. Either that or add a new column to the table for each entry.

  • Problem in query detail block

    hello all,
    i have a form having master and detail block. in master we have store_cd and location code(primary key in master table),
    based on that detail recrds fetch in detail block. perfectly fine. but when i query within detail block records then it show no record found. please tell me what can be wrong.
    detail table primary key is (store_cd, location_code and storage_co) , in realtion i mentioned

    Thanks
