DYNAMIC CHANGE OF TABLE CONTENTS IN WEBDYNPRO VIEW

Hi,
I have a requirement to display a table contents, and there are two buttons, When i select some records and clk on a button i need to delete these records in the database table as well as in webdynpro view.
I am able to delete the records in database but the contents of table in view of webdynpro remains unchanged. Can anyone tell me how to delete the contents in the view also??
Regards
Naveen

Hi Naveen,
You need to Refresh the data you are binding to the table to make the latest data
visible on the screen.
On action of the button you are deleting entries from the database. After this
Fetch data again from the database and bind to the node of the table.
Hope this solves your problem..
Regards,
Ismail.

How to dynamically change the table name inside a view

Hi All,
create table t_auto_feeds
id number,
table_name vachar2(100));
insert into t_auto_feeds values(1,'T_FEED_POSITIONS');
insert into t_auto_feeds values(2,'T_KAP_MTM');
assume there are 100 records on id=1 in T_FEED_POSITIONS and 100 records of id=2 in T_KAP_MTM (id 1 is present only in t_feed_positions & id 2 is present only in t_kap_mtm)
i need to create a view such that it needs to give the count of records based on the id
create or replace view aa_view as
select count(*), id from t_feed_position group by id
union
select count(*), id from t_kap_mtm group by id;
I am getting a proper result when i query the view like select * from aa_view where id=1 but will the other union query seems to be a overhead?. I am having 10 such tables configured for different id in t_auto_feeds.so do i need to put 10 unions or is there a better way to handle this stuff.
I know i can use a PLSQL block and dynamically build view structure, the problem is the view itself is configured in a table , so i cant write a proc for this.. can this aa_view be modified such that it queries only the table(using the t_auto_feeds ) which matches the id rather than the entire list.
Kindly help me in this regard and let me know in case u need any further information from my side.

>
so do i need to put 10 unions or is there a better way to handle this stuff.
>
Yes - you need 10 unions
Yes - there is a better way so that only one of the 10 queries does anything.
You can use SYS_CONTEXT to control the query selection.
Here is an example of using SYS_CONTEXT. Try this code in the SCOTT schema.
create or replace context VIEW_CTX using SET_VIEW_FLAG;
create or replace procedure SET_VIEW_FLAG ( p_table_name in varchar2 default 'EMP')
as
begin
dbms_session.set_context( 'VIEW_CTX', 'TABLE_NAME', upper(p_table_name));
end;
select * from emp where 'EMP' = sys_context( 'VIEW_CTX', 'TABLE_NAME' );
select * from emp1 where 'EMP1' = sys_context( 'VIEW_CTX', 'TABLE_NAME' );
select * from emp2 where 'EMP2' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
exec set_view_flag( p_table_name => 'EMP' );
exec set_view_flag( p_table_name => 'EMP1' );
exec set_view_flag( p_table_name => 'EMP2');
SELECT sys_context( 'VIEW_CTX', 'TABLE_NAME' ) FROM DUAL
CREATE VIEW THREE_TABLE_EMP_VIEW AS
select * from emp where 'EMP' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
union all
select * from emp1 where 'EMP1' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
union all
select * from emp2 where 'EMP2' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
SELECT * FROM THREE_TABLE_EMP_VIEWNote that you set the context for the table you want. This doesn't have to be a table name it could just be flag value
-- use the emp table
exec set_view_flag( p_table_name => 'EMP' );
-- ue the emp1 table
exec set_view_flag( p_table_name => 'EMP1' );
-- use the emp2 table
exec set_view_flag( p_table_name => 'EMP2');

Dynamically changing af:table range navigation

Hi Steve,
I have a requirement of changing range navigation on another variable "items per page" on the table.
1. User can select any number of items to be displayed at a time on page from a drop down with values 10,20,30 etc.
2. I have a valueChangeEvent Bound to this drop down to set the table rows.
public void itemsPerPageValueChange(ValueChangeEvent valueChangeEvent) {
// Add event code here...
if (valueChangeEvent.getNewValue() != null) {
Integer items = (Integer)valueChangeEvent.getNewValue();
getTable1().setRows(items);
This happens fine on the first page i.e. On page display. But say if there are more records then the selected value
in the dropdown, a table range navigation is displayed as expected. Now if i go to next set of records by "pressing next",
and select a larger value from "items per page", the list is not displayed as per the selected value. i.e. if there are 16 records
and i select 20, the display is still displaying the last six records. Only if i click "previous 10" on the table, do i get
20 records and the range navigation for the table disappears.
How can i control this?
1.I mean to always display number of records as selected by the user irrespective of which range of
records he is seeing.
2.To display correct value in "previous" and "next" navigation controls depending on value selected by user from dropdown
Thanks

Get informations whether changes in Table content before store

Hallo,
in my Web Dynpro Application I have a table. If the User changes something in this table I must get the Information in what row the changes are before I store.
Than I have to set a attribute in this row back.
Is there any possibility to do that. I have try to get the Information with the method "isChangedByClient()".
But I need the information at what row is the change.
Is there any Event?
Kind regards
Gunter

Hi Erik,
you are missing the data in the shift register!
You should initialize shift registers when you don't need data from previous runs of the VI…
Or get rid of the shift register when you don't need it:

How to dynamically change the table name for a update statement

Hi All,
I need to update a coulumn xyz in either of tables abc and efg based on some condition.
I wrote a cursor which has union of two queries(one querying abc and other efg)
Now based on some inparameter only one will be executed at a time.
And based on some condition a coulumn xyz needs to be updated which is in either of the table.
As the update condition is same
Update abc/efg set xyz=data where condition
I am looking to initialize a variable like v_tname based on some condition and update like
update v_tname .........
(Exactly that may not be like so, But looking a technique like this)
Please help

If there is only two tables you'll need to update then you are better off using static SQL and implementing something like this instead:
DECLARE
        update_condition        BOOLEAN;
BEGIN
        -- initialize update_condition
        update_condition := <some_boolean_check>;
        IF update_condition
        THEN
                UPDATE abc
                SET    xyz = some_val
                WHERE some_col = some_other_val;
        ELSE
                UPDATE fgh
                SET    xyz = some_val
                WHERE some_col = some_other_val;
        END IF;
END;
/Hope this helps!

Dynamically changing attributes of a field in view container UI element

In the layout of the web dynpro component I have added a view container UI element. I am populating the fields in the view container UI element in methods in component controller using the following code
*--Adding a Checkbox
lv_str = wd_assist->if_wd_component_assistance~get_text( '009' ).
CALL METHOD wd_this->att_wd_handler->add_parameter_field
    EXPORTING
      i_id          = 'CHB_DOWNLOAD_CHECKBOX'
      i_description = lv_str
      i_value       = lv_chb_download_checkbox
      i_as_checkbox = abap_true.
*--Adding a Parameter
    lv_str = wd_assist->if_wd_component_assistance~get_text( '010' ).
    CALL METHOD wd_this->att_wd_handler->add_parameter_field
      EXPORTING
        i_id          = 'CHB_DOWNLOAD_PATH'
        i_description = lv_str
        i_value       = lv_chb_download_path
        i_as_checkbox = abap_false.
Now based on the checkbox selection I want to make the field CHB_DOWNLOAD_PATH mandatory and also on F4 for CHB_DOWNLOAD_PATH I want a method to be called. Where must i write the coding for the above conditions and how? Please help.

hi
In your method there would be a parameter ie ON_TOGGLE where you can write the name of your event .
Whenever your checkbox will be clicked that event wil be called.
You can write your code in that event itself.

Dynamically change table selecting from

in 3.2 on 11g database is there a way to dynamically change the table used in a select statement for an interactive report? I have a series of similar tables, one for each month of the year. I want to click a month on one page and bring up a report from the table for that month. I want to use one page for this report and have all links from previous page link to the same page, just different result based on what month was clicked.
I know I could just setup 12 different reports and conditionally display each region based on a value passed to the that page, but I'd prefer to only create one page & one report on that page.
Thanks for any ideas or solutions.

Your function will have the code dynamically built.. What you do is you build your sql and pass in the table name and any other items that will change based upon your requirements..
here is an example...
function inventory_report (p_State IN VARCHAR2) RETURN VARCHAR2 IS
declare
q varchar2(4000);
begin
q:='   select p.category, ';
q:=q||'       p.product_name, ';
q:=q||'       p.quantity, ';
q:=q||'       p.unit_price ';
-- Here is where we substitute the passed in state name for the data table we extract data from
q:=q||' from ' || V('p_State') || ' p, ';
q:=q||' where p.product_quantity > 0 ';
return q;
end;Thank you,

How to change the images dynamically in a table.

Hai,
How to change the images dynamically in a table based on the condition in webdynpro abap.
Edited by: Ravi.Seela on Oct 13, 2011 2:17 PM

This has been much discussed earlier. Do search posts.
For your scenario i would do the following.
inside your node which is binded to the table, i create a new node image with cardinality 1 ..1 and a attribute called path of type string.
create a supply function for the node image .
Supply method now has a Element (Parent element ) and node.
Based on your record in element, set the right image source to path attribute and bind the node.
This will make sure that the framework calls the image supply function for every row in a table.

Dynamically change the Binding of a view object

I want to reuse a panel several times in my application. The VO has one bind parameter (:1). The same panel should be reused several times with different bind variables.
I found a technical note concerning this issue called: How to Dynamically Change the binding of a View Object to a JClient Panel. This works for JDeveloper 9i but not for JDeveloper 19g. Does anybody know how to dynamically change the binding in JDeveloper 10g

You may use bindRowSetIterator() and pass in a custom fetched ViewObject or a RowSetIterator to the iterator binding that is displayed in your panel.
