Problem in sorting of table data

Hi all,
I had gone through the PDF given (Developing with tables in webdynpro).
i got struck in creating TableSorter.java file...
can any one tell me how to create that java file in my project and how to send the colum which i want to sort to TableSorter.java
Regards
Padma

To implement it ,create a value attribute say "sorter" of java native type
com.sap.tc.webdynpro.tests.utils.TableSorter. (The package name MIGHT be different.)
In wdDoModifyView,obtaine a refernce to the table objject like
table = (IWDTable)view.getElement("table ui name);
and use
wdContext.currentContextElement().setSorter(
new TableSorter(table, wdThis.wdGet
<action name for sort>Action(), null));
Now inside that action handler,
wdContext.currentContextElement().getTableSorter().sort(wdEvent,
wdContext.node<nodename>());
also chk it

Character problem in toad import table data from excel

Hi everybody,
I want to import data from an excel file to an Oracle table, so I'm using Toad's "Import Table Data" tool for this purpose.
The problem is Oracle doesn't import non-english characters properly.
My database is XE and character set is 'AL32UTF8'.
I searched web, but didn't find the solution.
Please help...

Hi again,
Thank you for your reply Srini, but it is not about Toad.
Character encoding of Excel causes the problem.
I exported an unicode encoded csv file from excel and tried to load data from that file. It worked.
Thanks.

Physical Sort on Table data

Is there a way to sort the records of a table physically?
The order by clause does a logical sort on the table data that is temporary.
Can we sort the records permanently?

In my environment your query is using a [ INDEX FAST FULL SCAN :|http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/optimops.htm#i52044] which is not guaranteed to follow physical ordering:
>
It cannot be used to eliminate a sort operation, because the data is not ordered by the index key. It reads the entire index using multiblock reads, unlike a full index scan, and can be parallelized.

Problem with pl/sql table data type

hai friends,
i have one procedure it has some in parameters and one out parameter which fetches values to front end.
But the out parameter will be pl/sql table data type.
if it is ref cursor
then i declared as
var x refcursor;
exec procedure_name(1,:x);
it is ok.
but for pl/sql table data type is out parameter then what i will do in the prompt .
give me syntax and clarify my doubt.
advanced thanks...
madhava

The SQL*Plus VARIABLE statement does not support user-defined types, hence it cannot support nested tables. It can support cursors because they can be weakly typed (so we can use the one SQL*Plus VAR to hold any shape of resultset). Nested tables are strongly typed; SQL*Plus is a relatively stupid interface and cannot be expected to understand UDT.
So, it you want to use nested tables as output you'll need to code a wrapping procedure that can understand your nested table type and handle it accordingly.
Sorry.
Cheers, APC

Check if your Programm is called at the Sapscript level.
Are you calling the programm from the Sapscript using the PERFORM command? or are these Programm and Sapscript set in customizing?
Using SE16 check the Message Type and see if Sapscript and the programm are connected at all.

Problem in sorting of table

Hi Friends:
    Below are the records in my table:
a...|b|c...... |d.....|e................|f
100||25000|......|0000012998|0002259999
100|*|25000|1405|0000012998|0002251405
100|*|25000|1406|0000012998|0002251406
100|*|25000|1407|0000012998|0002251407
100|*|25000|1409|0000012998|0002251409
100|*|25000|1410|0000012998|0002251410
100|*|25000|1411|0000012998|0002251411
100|*|25000|1419|0000012998|0002251419
100|*|25000|1420|0000012998|0002251420
100|*|25000|1421|0000012998|0002251421
a = client
b= Leg.Dept Code
c= Legacy Product
d= Legacy Location
e= Cost Center
f= Profit Center
Please consider '.' as space.
The problem arises in the sorting of the table records. The first record shown in the record set above has the following entry:
a...|b|c...... |d.....|e................|f
100||25000|......|0000012998|0002259999
This is the default entry that is to be used if there is no Leg.Location (where Leg. Location = *). If there is an entry for the specific Leg. Location, then it should be used prior to using this record.
Problem appears to be that the ABAP program locates this default record prior to encountering the specific record, for example:
a...|b|c...... |d.....|e................|f
100|*|25000|1419|0000012998|0002251419
Because the program encounters the wildcard one first, even if the Leg. Location that the program is searching for is 1419 (which appears in the table, just lower in the listing) the program returns a Profit Center of 2259999 instead of the correct value of 2251419.
Is it possible to change the native sort of this table so that the wildcard entries appear at the bottom of the listing instead of the top? If yes, can it be done permanently.
This would allow the program to encounter the specific entries prior to encountering the wildcard ones.

Problem in sorting Advanced Table

Hi,
I unable to sort the data in advanced table.The data in the table is populated from an external LOV.When i set the initial sort sequence attribute of the sortable column of the table it is sorting in desecnding order by default.How to sort the data in the ascending order.Please help me it is very urgent.
Thanks in advance
Regards
Srikanth

The sorting on the table is done by adding the order by clauase and then re querying the vo.
However here the data is coming from an LOV not from VO.
Hence what you need to do is add the order by clause to the VO of the multiselect LOV.
By making the LOV columns sortable (OR ASCENDING BY DEFAULT) and then sorting them in ascending order, see what comes to the base page?..
IF sorting on lov does not suffices and the need is to provide sorting on the base table is also needed then my suggestion is to associate the same vo of the lov with the advanced table (or put the same query of the lov vo for the advanced table vo)

Dynamic Sort on table control

Hi friends,
I am having a problem when sorting the table control dynamically based on the fields selectd.
sorting is not working, when you select multiple fields ( one numeric field and one character field ) I have written code for handling multiple field sort,gettting field names correctly, everything looks fine but internal table is not getting sorted.
Is it related unicode issue..?
Any help will be appreciated.
Sample code:
loop at tc_control into lc_cols.
case lc_cols-selected.
 wehn 'X'.
 split lc_cols-screen-name at '-' into gv_tabname gv_fieldname.
 move gv_fieldname gs_struc+lv_off(20)
 add 20 to lv_off.
endcase.
endloop.
if ok_code = 'ASCE'.
sort itab by (gs_struc-field1) (gs_struc-field2) ..... ascending
endif.
Thanks in advance
Thiru.p

Hi
Try using an internal table for the field names..
Example
DATA: BEGIN OF ITAB OCCURS 0,
 MATNR TYPE MATNR,
 WERKS TYPE WERKS_D,
 END OF ITAB.
DATA: ITAB_FIELD(30) OCCURS 0 WITH HEADER LINE.
DATA
ITAB-MATNR = 'ABC'.
ITAB-WERKS = 'ABCD'.
APPEND ITAB.
ITAB-MATNR = 'ABC'.
ITAB-WERKS = 'ABC'.
APPEND ITAB.
SORT INTERNAL TABLE
ITAB_FIELD = 'MATNR'.
APPEND ITAB_FIELD.
ITAB_FIELD = 'WERKS'.
APPEND ITAB_FIELD.
SORT ITAB BY (ITAB_FIELD).
LOOP AT ITAB.
WRITE: / ITAB-MATNR,ITAB-WERKS.
ENDLOOP.
Thanks

Sorting WD table

Hi all,
I have a small problem with sorting WD tables.
I have java bean model as datasource for table. In this bean, I have non-string attributes like date, etc. I want to format them, so I've added additional String attribute for every attribute I want to format.
When i'm click to sort (I use standard TableSorter) by some of additional String attribute (column with original attr. is invisible and I put that invisible column name to sortBy method to achieve correct sorting behaviour), I lost ascending/descending icon on that substituted column...
Have somebody solution for this?
Best Regards,
Michal

Hi,
If not how can I turn off sorting on such a columns.
As far, there is no such provision for table columns!. However in ALV, you can use IF_SALV_WD_SORT~SET_SORT_ALLOWED method to set sort on/off for ALV column.

Kiran

Problem in capturing the edited data while the table is sorted

hi,
i am using the TableSorter class provided by the sun tutorials to add sorting capability for my JTable. i need to print on the screen, the value of the cell whenever it is updated. so i am using TableModelListener and its tableChanged() method for this purpose. if i edit the data without applying the sorting then its printing fine. But if i edit the data with table sorted in a particular order by clicking on the table header then the tableChanged method is not being called. So some problem lies in the table sorter which is preventing the call to the tableChanged method whenver table it is sorted. Below is my implementation of JTable.
TableSorter sorter = new TableSorter(new MyTableModel());
final JTable table = new JTable(sorter);
table.getModel().addTableModelListener(new
TableModelListener()
 public void tableChanged(TableModelEvent e)
 int row = e.getFirstRow();
 int column = e.getColumn();
 System.out.println("Row: "+row+" Coloumn: "+column);
);Hope u understood the problem. plzz help
thanx

hi camickr,
However the row number displayed is always the row of
the TableModel before the data has been sorted. this is the feature i am trying for and couldnt achieve it. i do want to print the row of tablemodel before data is sorted but i am getting 0 and -1 as row and column numbers.
I never saw -1 as a column number.
if you have never seen -1 as column number then just compile and run the code given below. I just added a table model listener to the table model to capture data editing. So if u edit any cell without applying sorting then its row and column number is printed properly but if u sort a particlar column and with sorting on if u edit any cell you will get row No. as 0 and column No. as -1. try running below code and please let me know where the problem exists or post your code which worked without any of the above problems.
I believe the code was updated in Feb of this year,
so make sure you have the most recent version.yes i have the latest version of tablesorter.
below is my source code for table sorting just compile and run it

How to re-sort Table data like A-Z and Z-A

Hello Gurus,
How can i re-sort Table data based on last name or first name, once table filled data from backend(i mean, once executed RFC, Table will be filled with data records, after that i want to re-sort table).
Can you provide me code, how to do?
Thanks
Venkat.

Hi Venkat,
For sorting to table columns, you need to pick up the code from here and add into a java file within your development component.
http://wiki.sdn.sap.com/wiki/display/Snippets/TableSorterClassfor+WebDynpro
Then, you can call the constructor of the class and pass the arguments to enable table sorting in your code.
Refer to following blog for execution
http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=(J2EE3417100)ID1078501850DB00490474849923920126End?blog=/pub/wlg/3287
Let me know, if the problem persists.

Problem with sorting and filtering of table

Hello,
using VC 7.1 SP5 I have created [this|http://img232.imageshack.us/img232/2460/screenshotsr0.png] model. The webservice returns a collection of structured elements. The table is meant to display values of top-level attributes. This works as expected.
However, the table cannot be sorted or filtered. What is the reason for this? How can I fix that?
I tried to store the result of the web service in a data bridge. That did not succeed.
Best regards
Alexander

Hi Natty,
How are you trying to sort it?
I want to be able to sort the table by clicking on the table column headers. Furthermore, I want be able to filter the table by using the built-in table feature. However, table sorting and filtering seem to be disabled for this particular table, whereas other tables in my model provide the desired features.
Best regards
Alexander
