Definition of Table stamp using a tabular presentation


I have a form of Tabluar (update only) where 2 columns can be updated on
a table, something like:

Employee (table)
emp_name varchar2
Status char (1)
Modified_By varchar2

If the columns emp_name or status is changed, I want the Modified_By define
for this line.

Sounds easy, but I only know how to use the automatic treatment of the form of tables.

Thanks for any help.

The best sollution to use the trigger somethink like him:

-This generation of trigger id (PK), stamp date of creation and editing and creation of stamp as to who.
WE employee

-insertion, you can omit but it is very useful for
If: NEW. EM_ID is NULL then
end if;
: NEW. CREATED_BY: = nvl (v ('APP_USER'), USER);

: NEW. LAST_UPDATED_ON: = SYSDATE; -It is also useful
: NEW. Modified_By: = nvl (v ('APP_USER'), USER);

  • Changing the definition of table PS_TXN use SECUREFICHIERS

    Fusion Middleware Version:


    JDeveloper Build JDEVADF_11.

    Project: Custom Portal Application WebCenter integrated with ADF custom workflows.

    During our ADF application performance tests, we noticed that a lot of contention on the LOB segments for the table PS_TXN (supports transactions State passivation/activation).

    Movement of the LOB segment to use Oracle SECUREFICHIERS, most other tweaks to the definition of the table showed significantly reduce the contention as providing a much higher throughput for read and write operations.

    To implement these changes, we would like to modify the ADF internal script that creates the table in the first place rather manually, dropping the table or by using the online table reorganization.

    This approach is documented, and suggests that this can be done my edit script "adfbc_create_statesnapshottables.sql" located under the directory MIDDLEWARE_HOME/oracle_common/sql $.  We tried it, but after letting off the table in a test environment, ADF is re - create the table using the original definition when the application is done after the operation first move.

    The same scenario can also be found under $MIDDLEWARE_HOME/oracle_common/modules/oracle.adf.model_11.1.1/bin however edit this file also makes no difference.

    Does anyone know what script ADF uses to create the table, or if this is now coded in a class file or some other mechanism?

    Automatic creation of table PS_TXN is hardcoded in the oracle.jbo.pcoll.OraclePersistManager class. Have a look at the statements at the end of the OraclePersistManager.createTable () method (in line 904 according to my decompiler). Other SQL statements (for example to drop the table, to the updates/insertions/deletions in the table, etc.) are defined inside the class oracle.jbo.pcoll.TransactionTableSqlStrings. You can find these classes within $MIDDLEWARE_HOME/oracle_common/modules/oracle.adf.model_11.1.1/adfm.jar.

    If your database is not Oracle, but DB2 or MS SQL Server, then you should look at the classes oracle.jbo.pcoll.pmgr.DB2PersistManager and oracle.jbo.pcoll.pmgr.SQLServerPersistManager respectively.

    You can override the default value PersistManager (create a new class that extends oracle.jbo.pcoll.OraclePersistManager and override/change the createTable() method), and then specify the new class in the AOS "jbo.pcoll.mgr" configuration property CreateTable() method has a package-level visibility, it would be very easy to do. This approach is delicate and the efforts needed to make does not, in my opinion. If I were you, I would be to pre-create the necessary tables in PS_TXN updated the manually.


    PS Scripts SQL "adfbc_create_statesnapshottables.sql" aims to be used by advanced users who want to create their paintings previously manually. These scripts are not used by the infrastructure when it automatically creates the necessary tables.

  • Tabular presentation - PK_DISPLAY with name

    Hi all

    Request Express

    I have setup an example on

    Workspace: BRENTDEMO

    user: demo


    On page 2, I have a dynamic action

     jQuery.each($('input[name="f03"]'), function() {
         alert('Name = ' + $(this).val());
         var deptno =$(this).closest('tr').children('td[headers="DEPTNO_DISPLAY"]').find('input[name="f02"]').val()
         alert('deptno = ' + deptno);

    If you use firebug on the page, the DEPTNO_DISPLAY column has no name/id associated so obviously that this action will not warn the correct value.  How I would go about assigning an id/name of the DEPTNO_DISPLAY column to retrieve the value.  I want to get this value it is because I have a how to remove custom that needs the PK ID.  (Not in this application example).

    I tried to make the column DEPTNO_DISPLAY a text field (changing names in dynamic action).  However, it gives an error message of "current version of the data in the database has changed since the user initiated the update process. version of current line identifier = "6FC404C2EDDB998C91CD7473B6DDA6A5" line application version identifier = "D3B1B18D31905688985A3EA6D5F82FB2" (line 1).

    On page 3, I tried to adjust the sql query to read

    apex_item.text(10,deptno) as deptno_with_name
    from "#OWNER#"."DEPT"

    With dynamic Action

     jQuery.each($('input[name="f03"]'), function() {
         alert('Name = ' + $(this).val());
         var deptno =$(this).closest('tr').children('td[headers="DEPTNO_WITH_NAME"]').find('input[name="f10"]').val()
         alert('deptno = ' + deptno);

    This allows all work fine, except when a validation fails on the page.  If you set Dname null and try to send the page, the following error message is displayed in the form of tables:

    error report:

    ORA-01403: no data found

    ORA-06510: PL/SQL: not supported by the user-defined exception

    Now, if you are populating Dname with what either, and you're trying to send the page again, you receive the following error message:

    Current version of the data in the database has changed since the user initiated the update process. version of current line identifier = "A884FA378C851786DDFE3A33709CB23C" line application version identifier = "6FC404C2EDDB998C91CD7473B6DDA6A5" (line 2)

    I tried searching forums and I believe that page 3 does not work because the mixture of apex_items and a Query (updateable report) "SQL" does not work.  Please correct me if that's wrong.

    Does anyone have a solution on how I can retrieve the value of DEPTNO? Is the best solution to use a tabular presentation manual?  If more information is needed, please let me know.

    Thank you


    What about just using the text() td value?

    The javascript code for your dynamic action reads as as follows, and the alert shows what is desired:

     jQuery.each($('input[name="f03"]'), function() {
         alert('Name = ' + $(this).val());
         var deptno =$(this).closest('tr').children('td[headers="DEPTNO_DISPLAY"]').text();
         alert('deptno = ' + deptno);
  • Try to use the plugin to watermark on a tabular presentation

    Hi all - I'm currently running Application Express

    If I create a basic form I can select my watermark in the list of menu drop-down ' view as ", but this option is not available for me in my tabular presentation. I'd like to be able to get this to work so that a user could see the watermark on all entrable lines in tabular form.

    Is this just a limitation of the APEX and if so are there ways around that?

  • How to use a Select list on a second primary key column in a tabular presentation?


    I created a tabular presentation located on the details page of the user (form), that allows to manage roles for this user.

    The shape of table contains 3 elements:
    -> a checkbox
    -> user (PK) column is hidden, and its default value is generated by a function pl/sql (to submit the time), which refers to the element to username.
    -> the role of the column is displayed as a named select list LOV: add you a line, choose a role, submit, etc..

    But my ROLES table (not created by me...) contains 2 columns: USER and GRANTED_ROLE.
    The USER is the primary key, but a user can have multiple roles (= one line per role).
    GRANTED_ROLE is the second primary key, so that we can differentiate between one line of another.

    At the moment my tabular form has only one primary key (USER), so the GRANTED_ROLE can display as a list select.
    But, for this reason, in my opinion, remove the button do not work: all the lines of the user have the same key, so when I select a few lines to remove these, all lines in the form of tables are deleted.

    I don't know how my button Delete could recognize the subkey to remove only selected rows...
    Or maybe I should use a different type of region?

    Thanks for your help!

    In the process of ApplyMRD, try to specify the 'secondary key' column in the section "Source: Multi line Update and Delete"to the second column key in tabular form.»

  • Tabular presentation - column to turn it off (with picture) based on another value of the column

    Hi all

    I haven't worked much on tabular forms and JS. I'm looking for help in this regard.

    I'm working on a tabular presentation. with several editable fields... I need to disable a column (just for this single line), which contains an image, based on a field of LOV (static) list) (Y/N). The image column must be disabled if the value is N.

    My SQL for the report is something like this: (will keep things simple)





    (case when STATIC_LIST = "Y" THEN ' < a title = "Edit SAMPLE TBL" href = "f?) p = & APP_ID.:10: & APP_SESSION.:NO:P10_EMP_ID, P10_EMP_NAME :'|| EMP_ID | «, » || EMP_NAME | "" "> < img src =" "#IMAGE_PREFIX #SAMPLE.gif" border = '0' (> < /a > ' other ' ' end) as disable_col, "


    of sample_table

    I scoured the topics in this forum. Most of them were made using the table ID f_001, f_002.

    I tried to follow the same path by inspecting the item but the disable_col does not have any ID.  Let's say, f_003 is for the static list and f_004 is assigned to dept_name.

    I tried dynamic actions, but it did not work. Read in a topic that dynamic action does not work on tables. So I chose this approach. Is there a simpler way to solve this?

  • Get the selected value of a select list item in a tabular presentation.

    Hi, I have a tabular form and I'm trying to get the selected value of a select list item and store the selected value in a page element hidden elsewhere on the form of tables, so I can use this value.

    I already have something similar to the input on the tabular presentation elements.

    Get the initial values
    var line = $x_UpTill (this.triggeringElement, 'TR');
    numberOfItems var = $(' input [nom = "f12"]', ligne) [0];

    numberOfItems = 123456.123

    What I want to do is soemthing similar as above but capture the value of a select element in tabular form. I thought I could do something like:

    Get the selected value
    var line = $x_UpTill (this.triggeringElement, 'TR');
    numberOfItems var = $('selected [name = "f08"] .val ()', line) [0];

    But this method leaves the as undefined var numberOfItems.

    Please help me to find a way to identify the item 'select' in the tabular form called "f08" and get this value.

    I am a newbie to jQuery selectors etc...

    Thank you.

    Strange that you do not get an error when you run your 2nd selector.
    In any case for this kind of thing, see the HTML code of your tabular form and tell us what triggers, the element can be useful. Or better create an example at
    In any case, I see two errors:
    (1) is there any html element "not selected" instead, the LOV in the APEX element has the select tag
    (2) you can not write a. val() inside a selector that you must place it after your selection.

    So I'd like to rewrite your code to:
    var line = $x_UpTill (this.triggeringElement, 'TR');
    numberOfItems = $("select_[nom_="f08"]",_row).val () var [0];

I can't use a contextual list in this case, because it only returns a single value. I can get it works without problem on page elements.

    How can I go on the field reference record current in the form of my popup window?

    You can pass the names of items in a table for the popup and use some JavaScript to assign values to these elements by using something like

  • Tabular presentation displays lines not (although it should be)

    HI -.

    I have a page that contains a tabular presentation, which I call in an iframe. Frame recharge parent the tabular presentation when an item on a jquery tree is selected (settings for the new page).

    I open a page of the child who doesn't have any line in, choose 'Add new lines', then back to the parent page and select another node in the tree. Loading of the page of the child, but no data is displayed in my tabular form - even if there is data. I get a header and the line of paging only. If I click on the button "next" pagination, refreshes the page of the child and the data is displayed as I hope.

    I think that paging is being upset in some sort of page being refreshed by the parent to halfway between the creation of a new line and saving it.

    How can I say specifically the page re - load with regular pagination values? Or I'm doing something too hard?

    Thanks in advance - I would be recognizing all of the ideas, we're really stuck!


    Looks like you need to reset pagination when you click on the tree to recharge your tabular presentation, you can do this by putting "RP" in the URL that you call, here the section in the doc that explains the syntax of the URL:

    Then look at this description of URL:

    f? p = App:Page:Session:Request:Debug:ClearCache:itemNames:itemValues:PrinterFriendly

    ... you need to get PR in the position where it says ClearCache, for example (assuming that your tabular form is on page 10):

    f? p = & APP_ID: 10: & SESSION. : RP

    I just want to mention that when you use 4 APEX, you can actually refresh regions in a table through dynamic actions, without iFrames.
