Table sorter with onActionleadselect(null)

Dear Friends
I am able to sort the table..but if want to use onActionLeadSelect(null) in the modify view of my webdynpro..I cant get the column id if i use onActionLeadSelct(null)
i tried to display the column id but it is null;
if i use onActionLeadSelect(null) in modify view. Is it possible to sort the table?
i need to use onActionLeadSelect(null) in my webdynpro?
IS there any relation betwen them
In ActionLeadSelect i have tried to use
wdContext.<node table name>.<currentresult>.<getColumnFieldData>
i am getting some column data in my Action lead....
Will there be any impact on my sort method
Thanks in Advance

Dear friend
I have sorted the columns using TableSorter class
i am able to sort the table........
But my requiremnent i need to use the OnActionLead Select(null) in modify view
if i use onActionLeadSelct(null)...I need to get the table s column field value and use to cretae in modify view
if i use OnActionLeadSelcct then the sorted icons are not visible and also table is not sorted if i click on the column header of the table.....
Can we use onActionLeadSelect(null) in modify view...
and also tablesortAction both

Replace default table sort with order by on the view object

The Jdeveloper help for af:table says:
If the underlying model is not a CollectionModel , the Table automatically examines the actual data to determine which properties are sortable. Any column that has data that implements java.lang.Comparable is sortable. This automatic support cannot be nearly as efficient as coding sorting directly into a CollectionModel (for instance, by translating the sort into an "ORDER BY" SQL clause), but is sufficient for small data sets.
I have a database table with varchar2 columns that can contain string, date or number values. So in the af:table I want to sort the columns either in string, date or number order.
I tried creating a sort listener and in that listener set the view object order by clause and execute the query, but it does not affect the row order - it is always sorted as a string. I assume that the collection is doing its sort after I do the query, and overwriting the query order. I have tried disabling the sort in the listener by setting the sortcriteria to null but it has no effect.
Can anyone suggest how to stop the default sort re-ordering the rows, or else how to code sorting directly into the CollectionModel as suggested in the help.

By running in debug I discovered that when you click on a column heading to sort by the column values it actually sets the order by clause on the view object and executes a query. The help says that the default sorting is not as efficient as setting the order by clause - perhaps the help is out of date because default sorting does set the order by clause.
This means that you cannot do a column sort on a transient attribute. The attribute being sorted on must exist in the table/query.
The easiest solution is to override the setOrderByClause method on the view object. The string parameter is the column to order by eg "COLUMNA". If this column holds date values I can change it to something like "TO_CHAR(TO_DATE(COLUMNA,'DD-MON-YYYY'),'YYYYMMDD')". For numbers I do "LPAD(COLUMNA,10,'0')".
This works OK.

Pivot table sorting with month_id and average column in BI publisher temp

In my project we are using the Oracle BI analysis for creating reports in BI publisher.
At first we are creating the report in OBIEE answers then using it as data model in BI Pub.
My reporting table holds data like below:
Month_Name Year Month_Id Compensation Emp ID
JAN 2011 1000 50 1234
FEB 2011 1001 60 1235
We need to show the data in pivot format i.e period(concated month+year) in column and comepsation values as measure and emp id in rows.I also need to show percentage i.e sum(Compensation/no of selected of periods).
For average in OBIEE pivot i have create one calulated item. But I can't sort the data(for periods with the month_id) as its spillting the average column also.
How can i sort it? like JAN2011 FEB2011 MAR2011 in pivot
also in BI pub this calculated item not showing correct value.
Please help.

Hi,
You can achieve this requirement by sort order column based on the month number and year you can sort this criteria column.also by using time_key,if the time_key is in sequence.
mark if helpful/correct...

Table sorting with pagination

Hi,
I have implemented pagination for the table. I have start,previous,next,last buttons in the bottom of the table. It is working fine.
Generally if i click on column for sorting it will sort the columns in which where we are.(Suppose if we are in second page, it will sort the rows only in 2nd page as i am using range paging for VO.)
But,instead of sorting rows on the specific page client is asking me to do the sorting on all rows in the table and display it accordingly.
Here i m not able to sort the rows in the sort listener.
Let me explain u with example.
I have 2 columns in the table name,age. and displaying 5 rows per page. and rows are like A,B,C,D,E in first page and F,G,H,I,J,K are in 2 nd page..
Name| Age
A
B
C
D
E
now if i click on column Name for sorting for desc it gives E,D,C,B,A ,for ASc it gives A,B,C,D,E ...
But for me if i click on desc the rows should be in the order of K,J,I,H,G,F..
After ascending
Name| Age
A
B
C
D
E
After descending
Name| Age
K
J
I
H
G
F
Here is the my code for pagination on click of pagination buttons : Just am setting scroll range for the VO terator..
JUCtrlRangeBinding staffView = getStaffView();
int prePage =staffView.getIteratorBinding().getNavigatableRowIterator().getRangeStart() / RANGE_SIZE + 1;
ViewObject vo = staffView.getIteratorBinding().getViewObject();
vo.setAccessMode(vo.RANGE_PAGING);
staffView.getIteratorBinding().getNavigatableRowIterator().scrollRange(RANGE_SIZE * (this.pageNumber -prePage));
any idea about how to implement sort accordingly for table?
Hope you understand ,you problem..Let me know if any questions..
Thanks..

let me give it a hit: Can you try setting the query execution mode to database just before you start sorting ?

Hi to all,
i've solved, is very simple using decode inside the select:
SELECT
ID,
FK_HTMLDB_ITEM, DECODE(FK_HTMLDB_ITEM,1,HTMLDB_ITEM.DATE_POPUP(3,rownum,VAL,'dd-mon-yyyy'),2,HTMLDB_ITEM.TEXT(3,VAL)) VALORE
FROM TESTID
my table is:
CREATE TABLE "DEV"."TESTID"
( "ID" NUMBER NOT NULL ENABLE,
 "FK_HTMLDB_ITEM" NUMBER,
 "VAL" VARCHAR2(4000 BYTE))

SRM MDM, Error, "Table with Code 'null' does not exist in repository"

Hi experts,
We has SRM MDM scenario, while doing OCI settings, we are able to connect with MDM repository but getting follwoing error message in portal, "java.lang.IllegalArgumentException: Table with Code 'null' does not exist in the repository 'Repository' or is one of the system table (e.g. Workflows) that is not exposed in repository schema"
Can You please suggest,
Thanks and Regards,
Munish

Hi everyone,
Sudhanshu and Anshuk:- Thanks for your response, let me try and explain the real scenario in details:-
We have deployed the SRM-MDM Catalog Search UI in Portal.
We tried accessing the http://<Portal Host>:<Portal Port>/SRM-MDM/SRM_MDM
Then we got a screen (Search UI App screen), where in we have provided the MDM Server name, then the MDM Server Password, then presses the Connect button, then below this, it displayed the Repository name created in the MDM. We have selected the Repository, then provided the Credentials of a User (Name: T_CORP) in MDM which has "Catalog Manager", and the "UI Configuration Manager" Roles. Please note that these Role names were created by us in MDM. Is it the right procedure or do we have any standard Roles delivered by SAP in MDM to map? If any standard Roles are available, where we need to check these.
Once the Credentials of MDM User is provided, and then selected the "Login" button.
Then we are getting the below error.
"java.lang.IllegalArgumentException: Table with Code 'null' does not exist in the repository 'Repository' or is one of the system table (e.g. Workflows) that is not exposed in repository schema"
Please clarify; we are not configuring any values in iViews. Where we need to do this, I mean name of the iView, and what values do we need provide generally? We are just running the Search UI App application; I don't think it is an iView, because the URL shows the Application name details, etc...
Please guide us, how to fix this Error.
Thanks and Regards,
Munish

Need help using GO URL to display table view (with sorting, pagination)

I'm trying to use the GO URL to get to a table view with the sorting and pagination functionality intact, but I don't want all the other links and input fields of a dashboard.
Is this possible?
I'm trying to consume table view report in an IFRAME within my web application using the GO URL, but without any luck.
For proof of concept, I'm trying to extend Sample Lite\KPI\Sample PKI which I can display as a dashboard in my IFRAME, but I would like the table view with the column sorting and pagination functionality intact without the dashboard links and fields up at the top.
I'm new to Oracle BI, specific explanation and step by step examples would help me tremendously.
I am on Oracle 11g v11.1.7.0 on RH linux.
The GO URL I am using:
http://myserver:port/analytics/saw.dll?Go&NQUser=username&NQPassword=password&Path=/shared/Sample%20Lite/KPIs/Sample%20KPI&ViewName=Table
Thanks.

Help with basic ABAP code (merge internal tables, sort of...)

Hello,
Can someone please help write some basic code for a Basis guy with limited ABAP knowledge?
Should be some easy points for an experienced ABAPer!
I have identicaly structured internal tables I_A and I_B and I_C which have already been filled by function models I called.
How will I code the following?:
I want to read all the data of I_A into a new internal table I_MASTER (structured the same as I_A,I_B and I_C).
Then I want to read I_B and:
1)Update I_MASTER with NEW records
2)Update existing records if the value of field MYFIELD in I_B is smaller than the value of MYFIELD in I_MASTER.
Then I want to read I_C and:
1)Update I_MASTER with NEW records
2)Update existing records if the value of field MYFIELD in I_C is smaller than the value of MYFIELD in I_MASTER.
Let me know if I can provide anymore information.
Thanks in advance for you help!

EPMA 11.1.2.1 (Interface Tables) Working with Shared Upper Level Members

Hi Everyone,
I am building a hierarchy with interface tables in which I specify a shared member. In the interface table, I assign a null datastorage and a 0 for the ISPrimary to designate the shared member. The stored member has a datastorage of storedata and an ISPrimary of 1. The sort order for the shared member is set at 999999 and the sort order for the stored member is 6.
We have an org hierarchy that goes Division->Business Group->Department. Please reference the member that is highlighted for the two questions I have below.
I just made up some hierarchy names and placed in parenthesis what the member name would look like in our real hierarchy.
Example Hierarchy:
Organization
|--Main_Hierarchy
|--|--Division1 (DV_XYZ)
|--|--|--BusinessGroup1 (BG_ABCD)
|--|--|--|--Department1 (DP_1234)
|-Alternate Rollup
*|--|--Division2 (DV_ABC) [stored]*
|--|--|--BG_123
|--|--|--|--DP_9999
|--|--|--|--DP_9876
|--|--Research Division (DV_ZZZ)
*|--|--|--Division2(DV_ABC) [shared]*
I have 2 issues with this setup.
1) When I run an import into the shared library, I see the shared member with children underneath it (the same children that are under the stored member) Is this supposed to look like that, or is there an additional configuration that I need to make? When I look in the application library, I see it correctly with the shared members having no children, but the shared library shows the shared members with children.
2) When I run a deploy to the application, the application library shows the hierarchy correctly, but Planning and the Essbase Outline reversed the members (The stored member comes in as shared and the shared member comes in as stored in essbase and planning, but the application library shows it the correct way). Just wondering if someone could suggest a starting point for me to try and troubleshoot this issue.

Is this an essbase only application? It seems like the property is defaulting to stored and then flipping the initial stored member to shared because Essbase isn't interpreting the deployment correctly. I would try using ShareData as the datastorage property (I think that is the correct spelling). Also, I believe the correct way to set IsPrimary is Y/N and not 0/1.
If that did not work I would try the following in this order:
1 - I would first extract the dimension in question using the file generator and confirm that the properties are indeed correct.
2 - If they were correct. I would toggle the dimension from shared->local->shared. EPMA is still a little nutty and this will fix a fair amount of issues as it will 'refresh' the application's version of the dimension. I would then deploy
3 - deploy from EPMA->Planning only (no essbase creation), then deploy to essbase separately after ensuring the property represents itself in planning. If it is essbase only - create the outlnie instead of refresh.
4 - create a duplicate app in EPMA and deploy the copy of the app - and see if it has the same problem
Try that and see how it goes.

Custom table model, table sorter, and cell renderer to use hidden columns

Hello,
I'm having a hard time figuring out the best way to go about this. I currently have a JTable with an custom table model to make the cells immutable. Furthermore, I have a "hidden" column in the table model so that I can access the items selected from a database by their recid, and then another hidden column that keeps track of the appropriate color for a custom cell renderer.
Subject -- Sender -- Date hidden rec id color
Hello Pete Jan 15, 2003 2900 blue
Basically, when a row is selected, it grabs the record id from the hidden column. This essentially allows me to have a data[][] object independent of the one that is used to display the JTable. Instinctively, this does not seem right, but I don't know how else to do it. I know that the DefaultTableModel uses a Vector even when it's constructed with an array and I've read elsewhere that it's not a good idea to do what I'm trying to do.
The other complication is that I have a table sorter as well. So, when it sorts the objects in the table, I have it recreate the data array and then set the data array of the ImmutableTableModel when it has rearranged all of the items in the array.
On top of this, I have a custom cell renderer as well. This checks yet another hidden field and displays the row accordingly. So, not only does the table sort need to inform the table model of a change in the data structure, but also the cell renderer.
Is there a better way to keep the data in sync between all of these?

To the OP, having hidden columns is just fine, I do that all the time.. Nothing says you have to display ALL the info you have..
Now, the column appears to be sorting properly
whenever a new row is added. However, when I attempt
to remove the selected row, it now removes a seemingly
random row and I am left with an unselectable blank
line in my JTable.I have a class that uses an int[] to index the data.. The table model displays rows in order of the index, not the actual order of the data (in my case a Vector of Object[]'s).. Saves a lotta work when sorting..
If you're using a similar indexing scheme: If you're deleting a row, you have to delete the data in the vector at the INDEX table.getSelectedRow(), not the actual data contained at
vector.elementAt(table.getSelectedRow()). This would account for a seemingly 'random' row getting deleted, instead of the row you intend.
Because the row is unselectable, it sounds like you have a null in your model where you should have a row of data.. When you do
vector.removeElementAt(int), the Vector class packs itself. An array does not. If you have an array, when you delete the row you must make sure you dont have that gap.. Make a new array of
(old array length-1), populate it, and give it back to your model.. Using Vectors makes this automatic.
Also, you must make sure your model knows the data changed:
model.fireTableDataChanged(); otherwise it has no idea anything happened..
IDK if that's how you're doing it, but it sounds remarkably similar to what I went thru when I put all this together..

Table Sorting: How is firstVisibleRow being affected?

Dears,
I'm confused at table sorting using Tablesorter.java.
When sorting, how does Tablesorter affect the firstVisibleRow of the table?
In the "[Working with tables|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/90ac0015-d1c5-2a10-d788-aed89990811d]" sample SDN provided, when press "sorting asending" or "sort descending", the table's first visible row changes automatically.
I didn't understand why firstVisibleRow changed to be so. And I don't know how the firstVisibleRow will change to be.
I checked the code of Tablesorter, and I also tried to debug into it, but didn't find any track.
Any word is appreciated. Thanks in advance.

Table sorter

Hi,
 i have to implement a table sorter in one of my webdypro application. I have done all the steps mentioned in one of the blog and have also imported TableSorter.java class. i am getting sorting icons in column headers. but on clicking icon nothing happens...i think there is some problem with the java class which i have imported. So can anybody provide the code of tablesorter.java class.
Thanks in advance,
 Reena

Alter Table Add column not null default value

I want to add two columns to a table with not null and default as 0 for both columns
Can i write the whole in one statement or do i have to split statement
I tried this, but didn't work
alter table DWSODS01.DWT00301_ORD_DTL_OMS add (
COMB_ORD_FLG NUMBER(5,0) default 0 not null,
COMB_ORD_NO NUMBER(12,0)
default 0 not null);
How can i modify the code?

The site is wrong and makes up its own terminology as it goes along.
If the value for clustering factor approaches the number of blocks in the base table, then the index is said to be clustered. http://www.oracle.com/pls/db112/search?remark=quick_search&word=clustered+index
There is no create clustered index in Oracle.
- Clustering factor affects the efficiency of an index.
- There can be clustered tables that you can create indexes on.
- An Index Organized table is a similar concept to the Microsoft SQL Server clustered index, but it isn't the same thing at all.
