Refreshing only the single row of ADF Table

Hi All,
I have a webcenter application where the ADF Applications has been deployed.Now the Data is coming onto the ADF Tables from a webservice.In that particular table i need to refresh only the single row(whichever selected by the user to edit ) or even a particular field with the updated values as well as need to validate and to create a message box saying about the errors if the validation goes wrong.
Please suggest!!

Hi,
if "updated value" mean that the value got changed on the middle tier (not the browser client) then the update requires the table to be partially refreshed. If the user edits a row and in this row has dependent fields, then this can be achieved by partially refreshing the column. Note that ADF Faces tables don't refresh just one cell

I can only freeze the third row of Numbers, not all three

I am trying to freeze all three header rows on my numbers spreadsheet, but only the third one freezes. The top two do not freeze.

Hi dennis,
I don't understand what you are trying to describe. Perhaps a screenshot. Cmd-option-4

Make only the new row in a table editable and other rows display mode.

Hiii all,
I am working on the component GSWISET, there is a table view for substitutes, the requirement is to show all the rows in the table view in display mode. Whenever the user clicks the button (Add employee), a search popup triggers and the user selects an employee from that and it will come as a new row in the table view. Here I need to be able to make only the new row editable and all the other rows in display mode.
Could you please suggest a way to achieve this. Thanks for your time..

Hi,
Try with the code below in.htm page

IF controller->view_group_context->is_view_in_display_mode( controller ) = abap_true.

Insert only the updated Fields

I have a log table based on the master table. The master table have 50 fields. Any update in the master data has to be logged in a new table. So the master table will have only the last updated data.
Any change in the master table to be inserted in to a logged table. I need to insert only the updated fileds not all the fields.
How to write insert statement in forms 6i for inserting to a logged table where only the changed fields.
INSERT TO EMASTER_LOGTABLE
(ECODE,
ENAME,
EDEPT,
ETRADE
VALUES
(:ECODE,
:ENAME,
:EDEPT,
:ETRADE
Row will be inserted in to the EMASTER_LOGTABLE with the updated field only not all the field except primary.

Hi!
Whats about a new idea?
Create a new table:
create table EMASTER_HISTORY (
EMP_CODE        number(6), --> i don't know yours
CHANGED_COLUMN varchar2(30) not null,
CHANGED_USER    varchar2(30) default user not null,
CHANGE_TIME     date default sysdate not null,
OLD_VALUE       varchar2(4000),
NEW_VALUE       varchar2(4000) )
storage ( your storage );In your form create a pre-update-trigger on your block like:
declare
l_item varchar2(30) := get_block_property ( 'your_block', first_item );
l_data_old varchar2(4000);
l_data_new varchar2(4000);
begin
loop
if
   get_item_property ( 'your_block.' || l_item, item_type ) in ( 'BUTTON', 'IMAGE' )
then
    null;
elsif
    get_item_property ( 'your_block.' || l_item, database_value ) != name_in ( 'your_block.' || l_item ) OR
     ( get_item_property ( 'your_block.' || l_item, database_value ) is null AND name_in ( 'your_block.' || l_item ) is not null ) OR
     ( get_item_property ( 'your_block.' || l_item, database_value ) is not null AND name_in ( 'your_block.' || l_item ) is null )
then
    l_data_old := get_item_property ( 'your_block.' || l_item, database_value );
    l_data_new := name_in ( 'your_block.' || l_item );
    insert into test.emaster_history ( emp_code, changed_column, old_value, new_value )
    values ( :your_block.emp_code, l_item, l_data_old, l_data_new );
end if;
exit when l_item = get_block_property ( 'your_block', last_item );
l_item := get_item_property ( 'your_block.' || l_item, nextitem );
end loop;
exception
when others then message ( l_item || ': ' || nvl ( error_text, dbms_error_text ) );
end;So, for every updated item in your form you will have a record in EMASTER_HISTORY with timestamp
and you're able to read the history of data in every column in your emp_master table.
Addition:
The only disadvantage is, non database items may will be logged too.
This because i don't know a "clean" item property to find out, if a item is a database item.
The item property column_name is not required and could by null alltough the item is a database item.

64-bit driver only returns first row of table

I have a C++ application using ADO (the MSADO COM components) and the Oracle OLEDB provider for database access. The application works fine on a 32-bit computer using the 32-bit Oracle client and driver. However, when I run a 64-bit build of the application, running on a 64-bit computer (Windows Server 2008 x64), using the 64-bit Oracle client and driver, a SELECT operation returns only the first row of the table.
Note that this is only happening with the ActiveX ADO components. ADO.NET is not having a problem.
In both cases I am connecting to the same database, which is Oracle 10.2 (32-bit) running on a different server. I have tested with Oracle client 10.2.0.4 and 11.1.0.7 and got the same result in both cases.
I have reproduced the issue with a simple table (one column, NVARCHAR2(255)) and simple code.
In the code, I execute "select count(*) from tablename" and get the correct record count (more than one record). But when I then open the recordset ("select columnname from tablename"), ADO reports EndOfFile after I have read the first row and called MoveNext on the recordset.
My Oracle knowledge is limited so I don't know if there are driver properties I should be checking.
Anyone have ideas?
Thanks in advance.

For 10.2 it's fixed in 10204 Patch 21 and higher.
For 11.1 it's fixed in 11107 Patch 12 and higher.
Cheers,
Greg

Display only the result rows only by using condition or any other way

Hello Everybody,
I've a web report where I want to diplay ony the result rows and don't want to display the detail rows at all. I could hide the detail rows but these rows still appear without any value in the key figure fields.
I tried to revove the characteristic field from the drilldown but it doesn't show the report correctly. Then I tried to write a condition to filter the detail rows but this condition doesn't apply to the result rows so this effort also didn't work for me.
Is there anyway we can display the report with only the result rows ? I've already tried to find out a solution on SDN but couldn't get the solution eventhough I found many posts on this kind of requirement.
Any help would be greatly appreciated.
Thanks
Alok

Please explain when you say
"I tried to remove the characteristic field from the drill down but it doesn't show the report correctly"
What is problem there? What result do you get. If possible please provide details of columns layout and few numbers

Only the top row of buttons works on the aluminun wireless keyboard

After returning my first wireless keyboard for not pairing with my iMac (which has all the right tech specs) I exchanged it for a new one. Initially, I was able to type letters and numbers only and many of the keys were not doing the task they were supposed to--the F12 keys ejected CDs and the eject button did nothing. I went to the Apple icon and downloaded all of the new updates that showed up, restarted my computer and then suddenly, the eject button worked! But, when I tried to type letters and numbers, nothing happened. My computer recognizes it and the top row of buttons works just fine.

the same has happend to me, it's a new wireless keyboard, and from the moment i paired them only the to row (f1,f2....eject) buttons are working.
what am i to do

How to Fix the 1st row in Table

How to Fix the 1st row in Table
In EP, one of the page we are getting out put in the table format. It's working fine, but as per the new requirement we have to fix (freeze) the first row of the table. (.i.e. whenever I click the page down button first row should be visible in the table). Can you help regarding the above issue?
For Example: in Table having 6 rows. In 1st row display Year Month and 2,3,4---etc Rows will display Quantity. Click on Page down Button in Table we are able to staring 2row. First was a movie up. So End user canu2019t find which year/moth under the Quantity is available.
So I have to fix in 1st row. Click on page down button table 1st row is fixed but comes to another Quantity Records.
It is Possible in Table? If possible please tell me.
Regards
Vijay Kalluri

Hi KalluriVijay
I don't think there is direct availabe method available to fix the row. However, there are two ways using which you can achieve the requirement:
To go ahead with the custom table. This way you can set your own properties for the table. However, this may impact performance handling large data.
Second option is to use other features of NW04s (Not available in NW04) like Table Popins using which you can achieve something similar.
For Table Popins refer [TablePopin|http://help.sap.com/saphelp_nw70/helpdata/EN/23/5e9041d3c72e7be10000000a1550b0/frameset.htm]

How to get only the changed rows in h:dataTable

As klejs said, set the valueChangeListener attribute to each of the input fields. Have a method in your backing bean which would
1) get the index from the component id
2) get the object and the above index from ArrayList
3) check if the old Value is different from the new value. If yes, set some boolean flag in that object to true indicating that the row is modified.
Sample code below. Please feel free to add checks if you need.
     public void updateDirtyFlag(ValueChangeEvent valueChangeEvent){
         if(valueChangeEvent.getOldValue()==null && valueChangeEvent.getNewValue()==null){
                 return;
         if(valueChangeEvent.getComponent().getId()==null){
             return;
      //Extract the index from the component id in the getId method
         int idVal=getId(valueChangeEvent.getComponent().getClientId(FacesContext.getCurrentInstance()));
         ArrayList dataList=getData(); // data from session or request scope
          if((valueChangeEvent.getOldValue()==null && valueChangeEvent.getNewValue()!=null)
                 || (valueChangeEvent.getOldValue()!=null && valueChangeEvent.getNewValue()==null)){
             if(dataList!=null && idVal<dataList.size() && idVal>-1){
                 YourBaseValueObject pojo=(YourBaseValueObject)dataList.get(idVal);
                 pojo.setUpdateFlag(true);
         else if(valueChangeEvent.getOldValue()!=null && valueChangeEvent.getNewValue()!=null && !valueChangeEvent.getOldValue().equals(valueChangeEvent.getNewValue())){
             if(dataList!=null && idVal<dataList.size() && idVal>-1){
                 YourBaseValueObject pojo=(YourBaseValueObject)dataList.get(idVal);
                 pojo.setUpdateFlag(true);
     }HTH.

How to Control the width of the Filter row in Table View

Hi !
I have a Table View with filter='application'. The filter works fine but I am not able to control the width of the columns of the tableview .
On filtering, if there are not items in the table view the columns shrink to the minum width....and it looks very odd.
Can you help me how to control the width of the Filter-Row in Table Veiw.
Thanks and Best Regards,
Bindiya

Hi Raja,
"FIXEDCOLUMN" did not help in the width of the column, but it just showed all the rows merged in the column.
I have a cloumn called "COUNTRY" and its width is set to "20". The Filter of the column "COUNTRY" is a dropdownlist whos value is update with new values.
On filtering if there is any row visible then the column width is adjusted to the maxmimum length of the dropdownlist ( this is because of the "EDIT" attribute in column definition ). But if there is no rows visiblel for the selected filter value then the filter row shrinks to the width = "20" and the dropdownlist is not visible completely.
Need to know how to control the width of the FILTER column.
Thanks and Best Regards,
Bindiya

af:table, only the first row of the table is effect

Hi experts,
I have an issue about using the <af:table, needs your help:
1.The default selected line is the first line of the table(This should be ok).
2.Only the first line can react to my manipulate, such as select one line and click delete button.
3.While choosing the other line-->click the command button, the page will be refreshed and the selected one will turned to the first line. (Now the selected row, will be the first row). And will do nothing ,and has no action with the command button.
I have an page OVS_Server.jspx, parts of it is :
<af:table value="#{backVS.serverList}"
var="row" rows="20"
emptyText="#{globalRes['ovs.site.noRows']}"

One JavaBean OVS_Server.java,and part of it is :
public class OVS_Server {

public void onSelect(SelectionEvent selectionEvent) {
selectedServer = (VirtualServer)serverListTable.getSelectedRowData();
public String deleteAction(){
if (selectedServer!=null) {
deleteServerOper.execute();
return "deleteServer";
Would anyone show some lights on it?
Thank you very much.

Thank you for your reply!
But the example you mentioned also has the issue like one of the comments :
"Hi, on selecting the first row it displays the correct value, when navigating to another row still it displays the old value and not fetching the new selected row, actually I can see this on your sample screen shots... is there any way we can fix??"
Is there any resolution?

Can one retrieve only the Nth row from a table?

Hi,
Can anyone explain the execution order of the below query to fetch the nth row data.
SELECT * FROM t1 a
WHERE n = (SELECT COUNT(rowid)
FROM t1 b
WHERE a.rowid >= b.rowid);
Thanks,
Satya.

If you're interested in a more efficient way to get the Nth row of the table, in order by ROWID:

Perhaps you should change that to 'tremendously more efficient'?
Ran some tests of the two using a table that contained 50+ thousand records created from ALL_OBJECTS
CREATE TABLE EMP_ALL_OBJECTS AS SELECT * FROM ALL_OBJECTSThen ran your query (modified for the new table) for r_num = 10000. It returned immediately and used 925 consistent gets.
Ran the original query (modified for the new table) for '10000 = '. It took 3 minutes and used 24189252 consistent gets.
Thought maybe it was a fluke so ran the orginal query for '1 = '. It took the same 3 minutes and used 24189253 consistent gets.
Maybe someone else could try to reproduce these results?

Looks like the original query is doing a probe of the entire 2nd table for each row of the 1st table - almost a CARTESIAN result. It takes the same time no matter which record you are looking for.
