Update JList from database table

Hi! I have a JList that take some value from a mysql table. I want that the JList add or remove value when insert or delete row from db table.
Can you help me?

Well then you need to write the add/remove code of the JList yourself. So when ever you updated the database you update the ListModel as well.
Read the JList API and follow the link to the Swing tutorial on "How to Use Lists" for a working example that dynamically updates a ListModel.

  • Update ztable from database table directly

    hi all,
    can u tell me the possible ways to update a ztable from database table directly.
    i mean is there anyway to update ztable whenever entry is created in database table .
    i dont want to update using insert,modify statements.
    points will be rewarded to all hlpful answers.

    A slightly dirty solution:
    Use SAP functions for reading from CDHEADER and CDPOS tables [with enough filters such that you extract minimum records possible] to read changes to MARA table fields since last run of your program. Use this information to update your ZTABLE. I would recommend having a table maintainance generator on ZTABLE. The actual update should be by a BDC by calling transaction SM30 for ZTABLE maintainance. Now the program may be set up as a batch job running 1ce an hour. You get updates to the extent of 1 hour latency.
    Alternatively, you may look if an opportunistic BADI / user Exit is there alongside MM01/02 transactions - assuming the latter are the only ones updating MARA. In this BADI you may write the code to update ZTABLE- again, look to do it by BDC call transaction sm30 to maintain ZTable. To lighten up the code -load on BADI you may simply raise a custom event and move on. You will configure a job that runs your program when that particular event is raised. This will need the 'burden' of figuring out the changes, though.
    An elegant way would be to fire a MATMAS fIDOC for every change to Material, capture that and turn back the changes to ZTABLE. This will facilitate the delta load.

    Hi
    how to create a external content type for  Read and Update data from two tables in  sqlserver using sharepoint designer 2010
    i created a bcs service using centraladministration site
    i have two tables in sqlserver

    and same time update  in two tables
    adil

    When I try to create an external content type based on a view (AdventureWorks2012.vSalesPerson) - I can display the data in an external list.  When I attempt to edit it, I get an error:

  • Efficient way of updating data to database table

    what is the efficient way of updating data to database table  .
    i have huge amount of data in my internal table  , how to use update statement in this case .
    1. database table having 20 fields  ,
    2. one is key field and suppose 20 th field i want to change  .
    3. I have data for only 2 fields , i.e for ( 1 st and last 20 th field ) .
    i can't use update statement in loop , as it is not good practice(hits database several times ) .
    do it effects all the 20 fields for  particular record .

    Hi,
    Use UPDATE statement , check below description from SAP help.
    UPDATE dbtab FROM TABLE itab. or UPDATE (dbtabname) FROM TABLE itab.
    Effect
    Mass update of several lines in a database table.Here, the primary key for identifying the lines tobe updated and the values to be changed are taken from the lines of theinternal table itab. 
    The system field SY-DBCNT contains the number of updated lines,i.e. the number of lines in the internal table itab which havekey values corresponding to lines in the database table.

  • How to delete a row from database table in facade client

    Hi all,
    I followed the tutorial in creating a persistence entity from database table, then a session facade. Then I followed the tutorial to create a sample client to test the model. In the session facade, I could use persistEntity method to insert a record to the database. I am just thinking of an extension to the tutorial, i.e., being able to delete the record too. So I created a new method removeEntity in the session facade
    public void removeEntity(Object entity) {
    entity=em.merge(entity);
    em.remove(entity);
    em.flush();
    and called it in the sample client. It was executed without any error, but the record in the table still exists.
    I tried to look around for a solution, but I did not find one. Would anybody here please help out? Many thanks in advance!

  • Dynamic record deletion from database table

    Hi,
    I need to delete selected records from database table(dynamic names). Table names are being passed from main program with some of their field names. The record to be deleted from the database table is being decided based on the fields passed for the table and their contains passed from the main program.
    It is not possible to write dynamic where clause for DELETE statement directly.
    So, I created a dynamic internal table and i am trying to fetch all records using SELECT statement(for which we can write dynamic where condition, something like...SELECT...WHERE (itab).  ) which need to be deleted in the iternal table.
    Piece of code :
              CONCATENATE c_im v_tablefield1 INTO v_imprtfield1.
              CONCATENATE v_tablefield1 c_in v_imprtfield1
                       into s_condition separated by space.
              APPEND s_condition TO t_condition.
              PERFORM GET_DYNAMIC_ITAB USING s_flds_agtab-tabname
                                    changing t_itab.
              ASSIGN t_itab->* TO <itab>.
    *Select the data (to be deleted) from the database table
               SELECT * FROM (s_flds_agtab-tabname) INTO TABLE <itab>
                 WHERE (t_condition).
    *Delete the records from the table
               IF SY-SUBRC = 0.
                 DELETE (s_flds_agtab-tabname) FROM TABLE <itab>.
               ENDIF.
    Here t_condition is of standard table of WHERETXT.
    t_condition at the run time before giving dump was:
    SPART IN IM_SPART
    AND KUNNR IN IM_KUNNR
    Here IM_SPART is renge type of SPART and IM_KUNNR is renge of KUNNR.
    I am getting a DUMP:
    The WHERE condition has an unexpected format.
    Error analysis                                                                               
    The current ABAP/4 program attempted to execute an ABAP/4 Open SQL
    statement containing a WHERE condition of the form WHERE (itab) or
    WHERE ... AND (itab). The part of the WHERE condition specified at
    runtime in the internal table itab contains the operator         
             IN (v1, ..., vn)                                        
    in incomplete form.                                              
    How to correct the error
    If the error occurred in a non-modified SAP program, you may be  
    able to find a solution in the SAP note system.                  
    If you have access to the note system yourself, use the following
    search criteria:                                                 
    "SAPSQL_IN_ILLEGAL_LIST"                               
    "SAPLZSD_TAB_REFRESH " or "LZSD_TAB_REFRESHU01 "       
    "Z_SD_REFRESH_AGTABLES"                                
    If you cannot solve the problem yourself, please send the
    following documents to SAP:                             
    I would like to know whether "IN" operator is allowed in (itab) of WHERE clause. While testing I changed the "IN" to "=" specifying a suitable value there. It worked. So please let me know if i can give "IN" operator using renge table in the dynamic where clause.
    Thanking you,
    Surya

    Hi again,  so if you can not use the IN in a dynamic where clause you might be forced to dynamically build the entire select statement,  Here is a sample program which may give you some ideas, notice that we are writing the select statement code, putting it in another program and generating the subroutine at runtime, then call this routine.  I'm sure that this will help you see what you need to do.

  • How to update Records from Internal table to u2018Zu2019 table?

    Hi Friends,
    How to update Records from Internal table to u2018Zu2019 table.
    I have records in Internal table , that records want to update on u2018Zmarau2019 Table.
    ( my internal table & u2018 Zu2019 table structures are same.)
    Thanking you.
    Regards,

    Hi,
    loop at internal table.
    modify <Z- table > from values < internal table Workarea>.
    if sy-subrc = 0.
      COMMIT work.
    else.
      ROLLBACK waork.
    endif.

    If I understand you correctly then I need to first export the xml file using Data-> Load sample XML data and later create template in template.rtf and upload data using APEX in template. In this case I need to create rtf template exactly similar to http://www.uscis.gov/files/form/I-9.pdf.
    I am not sure is there any way to to used existing pdf template or save pdf template to rtf template. Later that template can be used to populate data using APEX.

  • XSD from Database table/view/procedure

    Hi all,
    Does anyone know of a tool or framework which enables generation of XSD's out of a Database table/view/procedure?

    Hi Naval,
    It depends on whether you created a BOL model for your Z-table or not. If you don't have a BOL model, then all you can do is use a value node. In that case, you need to add attribute that you want to show in the value node, read the values from the z-table and add them to the node. You can create method(s) in view implementation class to read values from database table and fill the context node. From where these methods should then be called will depend on your requirement.

  • Delete from database Table

    Hi,
    To delete data from database table using internal table I am using following statement.
    DELETE dbtab       FROM TABLE itab.
    Itab is a sorted table.Just wondering if table type matters while deleting database entries using internal table.which is efficient table type for deleting records from database table?
    Regards

    Hi Nilesh
    The row type of the internal table must be a data object with at least the same length and alignment as the key structure of the database table. The key is read according to the structure of the table line, and not that of the row type. It is a good idea to define the row type with reference to the structure of the database table.
    From SAP Help
    DATA: BEGIN OF WA,
    CARRID TYPE SPFLI-CARRID,
    CONNID TYPE SPFLI-CONNID,
    END OF WA,
    ITAB LIKE HASHED TABLE OF WA
    WITH UNIQUE KEY CARRID CONNID.
    WA-CARRID = 'UA'. WA-CONNID = '0011'.
    INSERT WA INTO TABLE ITAB.
    WA-CARRID = 'LH'. WA-CONNID = '1245'.
    INSERT WA INTO TABLE ITAB.
    WA-CARRID = 'AA'. WA-CONNID = '4574'.
    INSERT WA INTO TABLE ITAB.
    DELETE SPFLI FROM TABLE ITAB.
    Besides, it is so technical what algorithm is run to delete records from the DB table when an internal table is given. If you want you can have a quick test using GET TIME. However, it seems logical that if your internal table is sorted with respect to any index, especially the primary index, of the DB table this may increase performance.
