  • How to display All the rows in a Table

    Hi All,
    Our requirement is, we need to display all the records of an VO in a table. We should not have navigation bar with previous and next. Runtime only will come to know how many records the VO has. Is it possible to achieve our requirement using setNumberOfRowsDisplayed() method in OATableBean ?

    Do u want to do it declaratively or programmatically.
    Declaratively You can set no of rows property of table bean. If u want to set it programmatically then u can do it as discussed in the thread..

  • How to display all the rows in a report

    How will it be possible to show all the rows in a report, in a table view , other than modifying the table properties for each report individually ?
    Is there some setting, so that for all tabular reports, all the rows will be displayed in one page?

    <DefaultRowsDisplayedInDelivery>2000</DefaultRowsDisplayedInDelivery>
    <DefaultRowsDisplayedInDownload>64000</DefaultRowsDisplayedInDownload>

    Hi,
    To display all the questions in a page instead of in a dialog, you can achieve it by using such an URL:
    http://yoursite/Lists/survey1/NewForm.aspx?IsDlg=0
    You can add a hyperlink with this URL into a page of your site, then you can navigate to the questions page by clicking this hyperlink.

  • How to display all the surveys using content query web part

    Can you please tell me how to display all the surveys using content query web part in more details? I also created a subsite and multiple surveys in that site. Then, I inserted a Content Query Web Part and select the List Type to be "Survey",
    however, it returned nothing. Did I miss anything?

    Hi,
    OOTB Survey List does not contain any
    Content Types and it has the following structure:
    Response entry is represented by
    List Item
    Response entry consist of questions and answers, where Question correspond to
    Field and Answer to Item value respectively.
    For querying Survey List via CQWP  the following properties could be used
    BaseType 
    <Lists BaseType="4">
    ServerTemplate
    <Lists ServerTemplate="102">
    Example
    To retrieve all the responses from Survey lists, specify List Type property as shown on picture

  • Display all the rows in the table with Varray

    I created two Varrays
    CREATE TYPE phone_varray AS VARRAY(3) OF NUMBER(10);
    CREATE TYPE email_varray AS VARRAY(3) OF varchar2(30);
    CREATE TABLE ee
    (id number(2),
    phone phone_varray);
    now i inserted some rows into ee table and displayed it as:
    SELECT e1.id,e2.COLUMN_VALUE"PHONE NO" FROM ee e1,TABLE(e1.phone) e2;
    ID PHONE NO
    1 1111111111
    1 2222222222

    4 2222
    4 33334
    5 1111
    5 2222

    Then i altered the table with email_varray
    desc ee;
    Name Null? Type
    ID NUMBER(2)
    PHONE PHONE_VARRAY
    EMAIL EMAIL_VARRAY
    I updated some rows:
    update ee e1 set email=email_varray('aasda') where id=4;
    and when i try to display the table data by:
    SELECT id,e2.*,e3.* from ee e1,TABLE(e1.phone) e2,TABLE(e1.email) e3;
    it only displays the rows that contain all the details like
    ID COLUMN_VALUE COLUMN_VALUE
    4 1111 aasda
    4 2222 aasda
    4 33334 aasda
    and not all the rows that are in the table which have id and phone and email as NULL
    need help to display all the rows in the table.

    will this work for you ?
    SELECT e1.id,e2.COLUMN_VALUE as PHONE_NO, null as email FROM ee e1,TABLE(e1.phone) e2

  • How to show all the rows of a report in one page

    My report has 30 rows, by default it just show 15 rows. I want to show all the rows just in one page, without cliking link or arrow to see the left.
    In the Layout and Pagination:
    Report Template: template: 15. Standard Report (PPR)
    Pagination Scheme: Row Ranges X to Y (no pagination)
    Display Position: Bottom - Right
    Number of Rows: 1000
    Number of Rows (item) 1000
    Maximum Row Count: 1000
    How to fix it?
    Thanks.
    Jen

    Ok, I think I got it. I needed to blank out Number of Rows(item), Maximum row count and only populate Number of Rows. I was sure I did that before and it didnt work.
    Do you think that the Sessions in Apex can cause unexpected results? I have found that when I make changes I have to log all the way out of Apex, close my browser and reopen everything to ensure that my change took. Does anyone else have this issue? I can move this into a different thread if need be.
    Thx!

  • How to show all the rows in PRint html option in obiee 11g

    Hi ,
    I am facing a issue in obiee 11g(windows 2003 server). I have 2 environments (SIT & dev)
    In dev I am not facing any issue but in SIT when i print the report in html only 1-25 rows are displayed.
    What should i do to see all the rows
    Thanks in advance
    Abdul

    Hi,
    In your Dev Server its configured on instanceconfig.xml file that why are getting the all rows with setting pdf/print control properties.
    1. Change instanceconfig.xml file in <biee11g_install>\instances\instance1\config\OracleBIPresentationServicesComponent\coreapplication_obips1 as following
    <Views>
    <Pivot>
    <!--This Configuration setting is managed by Oracle Business Intelligence Enterprise Manager-->
    <DefaultRowsDisplayedInDelivery>75</DefaultRowsDisplayedInDelivery>
    <!--This Configuration setting is managed by Oracle Business Intelligence Enterprise Manager-->
    <DefaultRowsDisplayedInDownload>2500</DefaultRowsDisplayedInDownload>
    <!--This Configuration setting is managed by Oracle Business Intelligence Enterprise Manager-->
    <DisableAutoPreview>false</DisableAutoPreview>
    <MaxVisibleColumns>5000</MaxVisibleColumns>
    <MaxVisiblePages>2500</MaxVisiblePages>
    <MaxVisibleRows>500000</MaxVisibleRows>
    <MaxVisibleSections>5000</MaxVisibleSections>
    </Pivot>
    <Table>
    <!--This Configuration setting is managed by Oracle Business Intelligence Enterprise Manager-->
    <DefaultRowsDisplayedInDelivery>75</DefaultRowsDisplayedInDelivery>
    <!--This Configuration setting is managed by Oracle Business Intelligence Enterprise Manager-->
    <DefaultRowsDisplayedInDownload>2500</DefaultRowsDisplayedInDownload>
    <MaxVisiblePages>2500</MaxVisiblePages>
    <MaxVisibleRows>500000</MaxVisibleRows>
    <MaxVisibleSections>5000</MaxVisibleSections>
    </Table>
    </Table>
    </Views>
    3. Note the new elements added are the following to both <Pivot> and <Table>, the Pivot part controls Pivot view, and Table part controls Table View, my testing was done with Table View.
    <MaxVisiblePages>2500</MaxVisiblePages>
    <MaxVisibleRows>500000</MaxVisibleRows>
    <MaxVisibleSections>5000</MaxVisibleSections>
    4. Restart Presentation Server from EM, then run your request, do pdf export to verify.
    Note:
    When a table or pivot table includes a large number of rows, a set of buttons can be displayed under the view. You can use the following buttons to page through the rows in the view:
    •First 25 Rows — Displays the first 25 rows of data for the view. The number that is used for the First, Previous, and Next buttons is specified by the Rows per Page field in the "Table Properties dialog: Style tab".
    •Previous 25 Rows — Displays the previous 25 rows of data for the view.
    •Next 25 Rows — Displays the next 25 rows of data for the view.
    •Display maximum (500) rows per page — Allows you to display as many as the maximum number of rows per page at one time temporarily. The default is 500. The administrator can specify a different maximum value that is displayed on the tooltip for the button using the MaxVisibleRows element in the configuration file.
    For more Refer my blog post
    http://obieeelegant.blogspot.sg/2011/09/unable-to-export-all-rows-from-request.html
    Note: this same thing you can also configure your UAT/Prod Server. then its will automated so you no need to configure each report.its will affect all the pivot/table view
    also its noted as a bug in obiee11g(11.1.1.3/5) and its fixed in obiee11.1.1.6.0 and above version
    FYI:
    Thanks

  • How to show all the rows in a report

    Thanks,
    Jen

    Jen,
    I'm guessing you are using Application Express,...
    Go to the region where the report is located, go to report attributes. In the "Layout and Pagination" section there is a setting called "Number of Rows". Change the setting, and that's it.

  • How do you make the rows in a JTable uneditable.

    Hi
    Does anyone knows how to make the rows in a JTable uneditable.
    --kirk                                                                                                                                                                                   

    Hi,
    implement a TableModel, e.g AbstractTableModel and use it to initialise
    your table. (JTable aTable = new JTable(myAbstractTableModel))
    And if you want your table to be editable implement isCellEditable() in your table model, and let it return true. If not let it return false, or don't implement it att all.
