The easiest way to do this: set a default value for the sort column in your backing bean.
Example:
     private String sortColumn="firstName";
     public String getSortColumn() {
          return sortColumn;
     <t:dataTable sortColumn="#{yourBean.sortColumn}" ... />On page load, the arrow is set by default to the firstname column.

  • How to get the last inserted record from a table ?

    :-) Hiee E'body
    I work on Oracle 8i and need to get the last
    record inserted in a table.
    I have tried using rownum and rowid pseudo-columns
    but that doesn't work.
    Can you please help me out ?
    :-) Have a nice time

    I'm not sure about 8i features.
    I assume here that you don't have 'Date-Time' stamp columns on the table which is the easiest way to determine the last inserted row in the table.
    If not try the following :-
    select address, piece, SQL_TEXT
    from V$SQLTEXT
    where upper(sql_text) like '%INSERT INTO TABLE_NAME%'
    Substiute the TABLE_NAME with the name of the actual table.
    Have fun.

  • How to get the previous state of my data after issuing coomit method

    How to get the previous state of some date after issuing commit method in entity bean (It should not use any offline storage )

    >
    Is there any way to get the state apart from using
    offline storage ?As I said the caller keeps a copy in memory.
    Naturally if it is no longer in memory then that is a problem.
    >
    and also what do you mean by auditlog?
    You keep track of every change to the database by keeping the old data. There are three ways:
    1. Each table has a version number/delete flag for each record. A record is never updated nor deleted. Instead a new record is created with a new version number and with the new data.
    2. Each table has a duplicate table which has all of the same columns. When the first table is modified the old data is moved to the duplicate table.
    3. A single table is used which has columns for 'table', 'field', 'data' and 'activity' (update, delete). When a change is made in any table then this table is updated. This is generally of limited useability due to the difficulty in recovering the data.
    All of the above can have a user id, timestamp, and/or additional information which is relevant to the data being changed.
    Note that ALL of this is persisted storage.
    I am not sure what this really has to do with "offline storage" unless you are using that term to refer to backed up data which is not readily available.

  • Can you programmatically change the width of columns in a table control\indicator

    Is it possible to programmatically change the width of columns in a table control\indicator ie to fit to width of the data or in my case the header information.

    Create a property node (or reference) and use the 'Active Cell' property to select which column you want to change and then use the 'Cell size'--> 'Width' property to change the size.

  • Get Total of a Column of Advanced Table and use it in Controller in OAF

    I have an advanced table on my custom page. I am calculating total of a column in my footer. I am acheiving this using the standard functionality of advanced table by setting total value property of my column to "TRUE" and displaying the total in the tablefooter components.
    In addition to this I want to retreive the total value from my footer and use it in my Controller for further validations but I am not able to acheive this.
    I tried some code already present in the Community for the same but nothing turned out right for me.
    Can anyone please help me on this.

       Hi there ,
      You can manually add the values of each row of a  column and make use of the value obtained in your controller .
    Here is the logic ,
    1) get the vo instnace attached to that table .
    2) Loop through every single row in the table .
    3) get the value and sum up the value and use it in your controller .
    int fetchRowCount = vo.getFetchRowCount();  
    voRowImpl row = null;  
    int count =0;
    if (fetchRowCount  > 0) { 
    RowSetIterator iter = vo.createRowSetIterator("Iter"); 
    iter.setRangeStart(0);
      iter.setRangeSize(fetchBidderRowCount);
       for (int i = 0; i < fetchBidderRowCount; i++) {
      row = voRowImpl iter.getRowAtRangeIndex(i);
       //use RowImpl getters   10.   
             Number personId = row.getPersonId();
    count =personId+count;         // add each and every value and have in variable
    iter.closeRowSetIterator();

  • Logic to build report to get the stock on a particular date

    Dear Guru's,
    We are trying to build a report for getting the stock on a particular date. It is not possible to copy MB5B that option is ruled out. We have also tried to get the data from MBEWH but that is also  not helping as the table is not updated for all the periods.
    Please advice
    Thanks,
    Sam

    Dear Sameer,
    You can copy MB5B report and can modify as per your reuirement.
    If you want get stock a paticular date.It is hard to get, why because you have to fetch all the Material documents
    and you have to use MBEW table to get the current date stock and you have to do add/subtract from calculated stock.
    Due to this there will performance issues also.
    So try to copy MB5B and change as per your requirement.

  • How to get the number of columns in a result set???

    hi everyone..
    i am trying to establish a servlet applet communication....
    my applet send the sql query to the servlet as serialised string and then the servlet executes the query...
    Since i need to pass the result back to the applet, i thaught of passing the whole reult set to the applet..but that seems to be not possible..
    so i thaught of storing my result set data in a vector and then pass the vector,but the first problem that i came across is that how to get the number of colums in a result set....
    so is there a way to get the number of columns in a result set...???
    and also i would like to know if it possible to send my whole result set to the applet bye serialization or by any method...???
    thanx in advance

    You shouldn't do. It expenses resources (you should always close the ResultSet and the Statement as fast as possible). Simply gently process it into a Collection or Map of DTO's. Those are serializable.

  • How to increase text size of a Column header of table in webdypro

    Hi All,
    Can anybody suggest me how to increase the text size of a column header of table in webdyrpo. I didnt find any option anywhere. can anybody help me out to solve this issue?
    Regards
    Ravikumar

    Hi Ravikumar,
    As Sukanta has suggested create a Simpletype of String Type and Length 40.
    Then create a context for the column header and for its type, instead of choosing
    from the drop down, choose the 3 dots.
    In the window that appears, select Local Dictionary, and Select the Simpletype
    that you have created, from the respective package name. And click OK.
    This will make the text of ColumnHeader of type String and Length 40.
    Hope it helps.
