Button in a table row to get value of a column.

Hello,
I am following [this thread|Re: Problem with getting table element's table row] to get the value of a column up on button click (the button is in the same row).
Here is the code in wdDoModify ()
if (firstTime)
          IWDButton button = (IWDButton) view.getElement("TableCellEditor");
          button.mappingOfOnAction().addSourceMapping("ScheduledCourses", "row");
Here is the code in the button action()
public void onActionRegisterStudent(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, com.gfc.hr.training.wdp.IPrivateCourseRegistrationCompView.IScheduledCoursesElement row )
    //@@begin onActionRegisterStudent(ServerEvent)
     wdContext.nodeScheduledCourses().setLeadSelection(row.index());
    //@@end
The context node for the table is "ScheduledCourses"
When I click the button, I get an exception....
com.sap.tc.webdynpro.services.exceptions.WDIllegalArgumentException: Parameter ScheduledCourses not found

Hi Srinivas,
Assuming you have a node 'ScheduledCourses' with two attributes 'courseId' and 'courseName' and you want to display the 'courseName' on click of the button placed in a particular row of the table, please try the following (Most of them you have already done, if i am not wrong. I am listing the entire steps so that you can check whether you have missed any thing).
1. Place a Table UI element and bind the datatsource property to the node 'ScheduledCourses'
2. Insert a new column in the table and for the column insert a table cell editor and select 'Button' from the list.
3. select the button(table cell editor) and create an action for the button. While creating an action create a parameter with name 'courseElement' and type as IPrivate<ViewName>.IScheduledCoursesElement (Interface representing element of ScheduledCourses node)
3. In wdDoModifyView() write the following code
    if(firstTime){
         IWDButton button=(IWDButton)view.getElement("Button1");
         button.mappingOfOnAction().addSourceMapping("nodeElement","courseElement");
Here "Button1" is the id of the button inserted in the table column. The string "nodeElement" should be written as such and "courseElement" is the name of the parameter which we have created for the action of the button.
4. Now in the action created for the button try to print the courseName as shown
wdComponentAPI.getMessageManager().reportSuccess(courseElement.getCourseName());

Get Row reference in advanced table to set the value of custom column

Hi,
I have a requirement to add a new column PHP Amount in Manage Charge page which is a entry page where all the charges are entered for a PO. This region is based on Advanced table.
As per requirement, Newly created column should populate the value of the existing column (Amount) or vice verse i.e. value entered in amount column should be set to PHP Amount column for a particular row. and the value entered in PHP amount should be stored in the custom table.
I have added the column via personalization and setting the view attribute in extended controller as this column is not the part of the database table on which the VO is based upon. Also added a PPR event in process request function in controller. And getting the reference of the row in processForm Request's PPR event and invoking the method defined in my custom AM for getting and setting the columns values . Here i can't extend the root AM as the Page have LOV columns so i have created my custom AM and adding it dynamically in controller.
Here is the complete code

I m not able to set the PHP Amount column value entered in Amount column. But i am able to set the Amount column value to PHP amount column.
I m not getting the Row Reference in case PPR event triggered in PHP Amount column . It is giving Null reference in case of PHP Amount.
I don't know what i m missing ..Can anyone help me here..
Thanks in advance
Renu

but using second way you will not be able to save those record in database, to save in database you have to override setter method also
Code will be like this -
    public String getBillRemarks() {
       return getSuppNmTrans(); // This is first Column Value
       // return (String) getAttributeInternal(BILLREMARKS);    }
    public void setBillRemarks(String value) {
       //Setting First Column Value in Second
       setAttributeInternal(BILLREMARKS, getSuppNmTrans());
But i suggest you to use valueChangeListener on first field to set value in second one

Satheesh Variath, I just had to make some corrections from your script to get the correct answer:
CREATE
VIEW vw_Comp
AS
SELECT
TOP 1 t.IDNO,t.name,t.[Date],t.Price1,t.Price2,
CASE
WHEN t.Price2
> LAG(Price2,1)
OVER (PARTITION
BY name
ORDER BY IDNO)
THEN 1
WHEN t.Price2
< LAG(Price2,1)
OVER (PARTITION
BY name
ORDER BY IDNo)
THEN -1
ELSE 0
END
AS Comp
FROM
@T t
ORDER
BY DATE
DESC
The adjustments: the selection of the most recent comparison (Top 1) and the use of the function LAG (instead of LEAD) to get the previous value of the column.

Quering table names containing a value in any column

I searched a bit around this forum and found a solution for how to query the list of all tables
select table_name from user_tables;
However, I do not know how to do this -
I want to find the list of all table names where any of the fields in these tables should have the value containing a number in it.
Say for example I have a database containing many tables Students, Teachers, Principals and many other such 100+ tables. I want to find the list of all tables names which contain the word "ohn" in any of their fields. The string "ohn" MAY be in Employees table under First Name field as John and in Teachers under Nick Name field as Johnny, etc.
So, I do not know what are the columns/field names. I only know that the value of any of these columns will contain the string "ohn" (like '%ohn%'). Now, how do I write a query for this which will give me the table names?
Please assist!

Well, this is by no means production code, but it should help you along the way to what you need.
create table test_1
column1 varchar2(100)
create table test_2
column1 number,
column2 varchar2(100),
column3 varchar2(100)
insert into test_1 values ('THIS WILL HAVE MY STRING WITHIN IT');
insert into test_2 values (1, 'WILL NOT QUALIFY', 'NEITHER WILL THIS');
commit;
declare
l_search_string   varchar2(100) := '%MY STRING%';
l_count           number;
begin
for everything in
select
    ' with data as (select :x as search_string from dual) select count(*) from ' || table_name || ' where ' || replace(search_string, '-', ' like (select search_string from data) or ') || ' like (select search_string from data) ' as sql_string, table_name
from
    select
      substr(MAX(SYS_CONNECT_BY_PATH(column_name,'-')), 2) as search_string, table_name
    from
      select
        row_number() over (partition by table_name order by 1) as rn,
        table_name,
        column_name
      from dba_tab_cols
      where table_name in ('TEST_1', 'TEST_2')
      and   data_type in ('CHAR', 'VARCHAR2', 'NVARCHAR2', 'NCHAR', 'CLOB')
    group by table_name
    start with rn = 1
    connect by prior table_name = table_name
    and rn = prior rn + 1
loop
execute immediate everything.sql_string into l_count using l_search_string;
if l_count > 0
then
    dbms_output.put_line(everything.table_name || ' has ' || l_count || ' rows ');
end if;
end loop;

Get the model when clicking a button on a table row

I have a SAPUI5 table binded with the simple model. I'm printing the data using Table control of SAPUI5. I'm binding the name field with the name column of the table control and on the next column I have a button. When you press this button I'd like to perform some operation on the model (read) however I can't figure out a way of getting the instance of the model in the callback function for the button.
Here's the JSBin to reproduce the problem.

Awesome.

How to get value in previous column and another row from Matrix with Custom Code?

I want to calculate the value of tb_Open and tb_Close. I try to use custom code for calculate them. tb_close is correct but tb_Open is not correct that show value = 0 .
This is example report:
* I have 2 Dataset , Dataset1 is all data for show in my report. Dataset2 is only first Open for first month
* First value of Open is item field in Dataset2 and this value only for first month (january). But for other month Open value get from Close in previous month.
Detail for Red number:
1. tb_Open -> tb_Close in previous month but first month from item field in Dataset2
expression =FormatNumber(Code.GetOpening(Fields!month.Value,First(Fields!open.Value, "Dataset2")))
2. tb_TOTAL1 group on item_part = 1
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)))
3. tb_TOTAL2 group on item_part = 3 or item_part = 4
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)) + ReportItems!tb_TOTAL1.Value )
4. tb_TOTAL3 group on item_part = 2
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)) - ReportItems!tb_TOTAL2 .Value)
5. tb_Close -> calculate from tb_TOTAL3 - tb_Open
expression =FormatNumber(Code.GetClosing(ReportItems!tb_TOTAL3.Value,ReportItems!tb_Open.Value))
My custom code:
Dim Shared prev_close As Double
Dim Shared now_close As Double
Dim Shared now_open As Double
Public Function GetClosing(TOTAL3 as Double,NowOpening as Double)
    now_close = TOTAL3 + NowOpening
    prev_close = now_close
    Return now_close
End Function
Public Function GetOpening(Month as String,NowOpen as Double)
    If Month = "1" Then
        now_open = NowOpen
    Else
        now_open = prev_close
    End If
    Return now_open
End Function
Thanks alot for your help!

I need to change the name to a different name for keys that are different. For same keys, the name must be same.
Here I need to rename the 'a' to different name, but make sure that the 'a' that have 2 as the key have same name .
Similarly, i've to rename the 'b' to different name , but make sure that the 'b' that have 5 as the key have the same name.
How can I achieve this in sql? I dont know how to use cursor and complex queries, as i'm new to SQL.
Please help
Thanks,

Set the color of a row depending the value of the column in JTable?

Hi All,
I have a JTable that add rows when the user clicks on the button. In this way there can be any no. of rows in my table. My table contains five columns. When a new row is added , it is added with new data each time. Also the data of the rows keep on changing time to time.
My problem is that when the data value for the third column comes out to be -ve then color of the row should be red and if its value is +ve then the color of the row should be green.
I have tried for this in the way but it is not working properly.
public Component prepareRenderer(TableCellRenderer renderer,int rowIndex, int vColIndex)
     Component c = super.prepareRenderer(renderer, rowIndex, vColIndex);
if(change<0 && rowIndex<table.getRowCount() )
          c.setForeground(Color.red);
          c.setFont(new Font("TimesRoman",Font.PLAIN,11));
else if(change>0&&rowIndex<table.getRowCount() )
c.setForeground(new Color(20,220,20));
     c.setFont(new Font("TimesRoman",Font.PLAIN,11));
return c;
where change is the value of the third column.
Any help is highly appreciated.
Thanx in advance.

Why do you have 3 postings on this topic all made within minutes of each other? (see [url http://forum.java.sun.com/thread.jspa?threadID=574547&tstart=0]here and [url http://forum.java.sun.com/thread.jspa?threadID=574543&tstart=0]here).
If you created a post by mistake then make a comment in the posting so people don't waste there time attempting to answer an old post.
where change is the value of the third column.How do you know "change" is the value of the third column? Did you use a System.out.println(...) to verify this.
A better approach is to use:
Object o = table.getModel().getValueAt(row, 2);
Then convert the Object to an int value and do your testing. This way you are guaranteed to be testing against the correct value.

Make 1 row turn into X rows, based on value X in column?

Hello everyone, got a question for you! I've got a table as follows:
ITEM_NUM,IN_STOCK
1001A,2
1001B,1
1001C,2
1001D,3
I'd like to get the following output:
1 1001A
2 1001A
3 1001B
4 1001C
5 1001C
6 1001D
7 1001D
8 1001D
So each row gets repeated for as many times as it has for the in_stock value. And down the left side, we get rownum.
I can do this with PL/SQL code (a cursor to get both columns, and for each row, run a loop to place these into a collection). But if there's a way just to skip the loop and write a query, I'd rather do this!
Thanks!

Dynamically adjust table row height based on data in column

Hi all,
I'm using JDeveloper 11.1.1.5.0 and have a requirement for a table to adjust the height of its rows depending on the data in the columns. One of the columns in the table is a rich text description field and I have the 'rows' property set to 13. This field could have twenty lines of text/images or just one. The users would like the page to show all twenty lines of text without having to scroll but the table has the same height for all the rows (that I set to 13) and provides a scroll bar when the data exceeds this size. My users do not like to scroll, and want the height of each row to be determined by the data in it. I looked at a few options and also did a search online, but was unable to find anything to fulfill this requirement. Do you know of how I could change the height of each row in the table so that it fits the data that it holds?
I have an example of my table at: <b>Table with Set Row Height</b>
As you see, the picture has to be scrolled so that the whole picture is visible. The user requirement is to adjust the row height to show the full picture. Ideally the next two rows would shrink, but that would be a nice to have.
Thanks in advance for any pointers or help.

Hi Frank,
Thank you for replying to my question, I truly appreciate your help.
I tried to use the autoHeightRows to adjust the height of my rows but was unsuccessful. If I understand the autoHeightRows property correctly, this is used for setting the height of the whole table. If this is incorrect and it can be used for setting the height of individual rows in the table, please correct me. I have the 'Rows' property of the richTextEditor set to 13 and this is the height that I would like to make dynamic based on the data.
My users requirement is for the height to be big enough for the data in each row of the table (the table has a description column and the height of each row should be determined by the data contained in it). I updated my <u><b>Screen Shot</b></u> to show the desired layout and what is currently being generated though ADF (http://www.flickr.com/photos/87583386@N05/) .
I have three rows in the example (in actuality these are around 50) and the text in each row can vary. The users would like to see the full text/image in each row without having to scroll each row. Currently my table is within Panel Box, which is inside a PanelGroupLayout-Scroll which is in a PanelStretchLayout. I tried to put the table by itself with the autoHeightRow modifications you suggested but thsi did not help either. I am using JDeveloper 11.1.1.6.
Is this possible with an ADF Table? If it is, is the autoHeight property the only one that I am setting incorrectly? If not, is there another component I can use to get the desired functionality? My users are very strict about this requirement and will not accept the application without this.
Thanks,

Input field validation in a Table based on the value of other column

Hi all
I have a table with 2 columns. column1 is of text view and column2 is Input field.
The user should not be allowed to enter a value in the column2 ( input field) greater than the value populated in column1(textview).
So for Eg; if the column1 is populated with value 100, The user should not be able to enter a number greater than 100 in the column2 input field.
Please let me how this can be achieved.
I appreciate the help.
Thanks

Hi,
Let me make sure u r working with table control.
First u have to create a event(VALIDATE) to do the validation.
Inside the event,
1. First get the current index where user has pointed the curson
2. Once u get the index read the internal table with index value.
3. Now u can compare the col1 and col2 values and populate the error message.
1. DATA : lo_elt TYPE REF TO if_wd_context_element,
l_index type i.
lo_elt = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
CALL METHOD LO_ELT->GET_INDEX( RECEIVING MY_INDEX = l_index.
above code should be written inside the event.
Thanks,

Choosing LOV in the table row , clears the rest of the columns

Hi. I am on Jdev 11g R3
I have a table with several editable columns. One of the columns is LOV
I put some data in the NON lov field.
Next I choose the value from LOV. As soon as I choose the value in LOV - the rest of the fields get cleared and appears empty.
I can solve it by setting "autosubmit=true" on each column, but I wander if there is an option to preserve column values without "autosubmit"
Please advice

Which version is 11g R3?
I only know abpout 11g R1 (11.1.1.0.0 - 11.1.1.7.0) and 11g R2 (11.1.2.0.0 - 11.1.2.4.0).
Where does the LOV store it's selected value?
Does this happen if you set the LOV to autoSubmit="true"?

Update a table based on Min value of a column of a Another Table.Pls Help.

Dear All,
Wishes,
Actually I need update statement some thing like below scenario...
Data in table is like below:
I wrote a query to fetch data like below ( actually scenario is each control number can have single or multiple PO under it ) (i used rank by to find parent to tree like show of data)
Table: T20
Control_no        P_no Col3
19950021     726473     00
19950036      731016     00
19950072     731990     00
                 731990 01
19950353     734732     00
                 734732 01
19950406     736189     00
             736588     01
             736588     02
             736588     03
Table : T30
Control_no      P_no              col3
19950021     726473
19950036     731016
19950072     731990
             731990
19950353     734732
              734732
19950406     736189
              736588
              736588
               736588
Now requirement is I need to update Table T30's col3 (which do have values in T20 but not this table) in such a way that , It should take MIN (COL3) from T20 and then update that value to related Col3)
Better I can explain through below new data format in T30 after update:
After update it should like:
Table : T30
Control_no       P_no    col3 (this is updated column)
19950021     726473   00 -- as this is min value for Pno 726473 belongs to Control NO 199950021 in Table T20 above
19950036     731016   00 -- as this is min value for Pno 726473 belongs to Control NO 199950021 in Table T20 above
19950072     731990   00 -- see here..both Pno should updated as '00' as MIN value col3 in Table T20 related to this
             731990      00     record is '00' (out of 00,01 it should select 00 and update that value here)
19950353     734732      00 -- same again both Pno should updated as '00' as MIN value col3 in TableT20 related to this
             734732      00     record is '00' (out of 00,01 it should select 00 and update that value here)
19950406     736189      00 -- As there is single col3 value in T20, 00 should be updated here.
             736588      01 -- Here it should update col3 as '01' since for this pno(736588)
             736588      01 -- Here too it should update col3 as 01 per requirement ,minimum value of this pno in T20
             736588      01 --     same here too.. Sorry if my post formatting is not good...
Hope i am clear in my requirement..(update T30 col3 based on min value of col3 of related records)
Please suggest some update sql for this...(ideas would be great)
I am using oracle 10 g version soon will be migrated to 11g..
Regards
Prasanth

hmm..thanks for your suggestion hoek..
so any ideas about my requirement...I would suggest spending a bit more time trying hoek's suggestion regarding {noformat}{noformat} tags instead of repeatedly asking for more help.

Get value based on column names for custom metadata field of Webcenter Content

In UCM, I created a custom metadata field of type Text. I then enabled optlist in that field. I populate values to the optList, I am using a View. The View has three columns. Let us call them ID, Key, Value. OptList displays the Keys in its list. I then create a Content (Content ID: MyContent) in Webcenter Content and choose values from OptList for my new metadata field (MyField).
From Webcenter Portal, I am populating a selectOneChoice with values of MyField in the Content ID: MyContent. Remember from previous step, the values populated in selectOneChoice is the list of values selected from optList field MyField. This optList is in-turn populated from View. After the user selects a value in selectOneChoice, in Javascript, I need to alert a message in this format "value chosen - corresponding value from View of optList that populates MyField"
I think an example will be useful:
Here is a View that I created in Configuration Manager applet in Admin Applets of Webcenter Content:
ID | State | Capital
1 | North Carolina | Raleigh
2 | California | Sacramento
3 | Illinois | Chicago
Then, I create a Custom Field (Name: MyField). MyField is an optList the values are populated from View created above. The internal value and display value are both State. Then I Check-In a new content with Content Id: MyContent. For MyContent, I select these values from OptList for MyField: {North Carolina, Illinois}.
In my Webcenter Portal application, I create a Content Presenter Taskflow. I configure it as a single item content presenter. I assign MyContent as Content Id. Then, in templateView, I get all values of MyField in MyContent and display them as selectOneChoice. I created a javascript function that would get the value that user selected in selectOneChoice. In the View created in Webcenter Content's Configuration Manager (above), there is a value corresponding to each value displayed. So, for the selected value, I need to get the corresponding Capital and display it in my alert message.
From Javascript, how can I get the value of Capital, given I have the value of State.

Hi.
The idea to achieve your requirement is next:
Create a helper manage bean that will be call as Map access: #{stateUtil['Calofironia']} (it will return Raleigh). This value will be get calling GET_SCHEMA_VIEW_VALUES IDC service using RIDC in your manage bean.
Pass the result of #{stateUtil['statename']} to your JavaScript function using <af:clientAttribute.../>
I hope this information help you.
Regards,
