How to save modified data

hi!
i'm jus starting to learn swing and i have come at the stage where i double click in a jTABLE n change the data there..but now i need to save all the changes in the table in a database, i have a Jbutton 'Save' but i dunno what to write as from there to save the new data. i've used actionlistener everywhere..
my database is found at a server in another computer and the interface is at client as usual.

Your table data has a TableModel that holds all data. Tou probably want to do something like (in actionPerformed, when the user presses the "store button":):
1. Connect to database
2. Get the model from the table
3. iterate all "rows" in model (a row normally contains several values)
a. fetch "row" from table's model
b. perform INSERT /UPDATE on database
4. Close database connection

  • How can I modify data from a Transparent Table without ABAP code.

    Hi,All
    How can I modify data from a Transparent Table (like TCURR),  and important thing is I want do all that with no ABAP code here. It is like that we always do that in a Oracle database use TOAD or PLSQL third party tools, with no script code here.
    I had fond that there is a way can do that:
    1, type 'se11',and Display Database table 'TCURR', click Contents, then click Execute to display all data
    2, type '/h' and let debugging on
    3, select one of this data then click 'Display',enter in debugging system.
    4, then make a breakpoint in the code. But... display a dialog let I type a 'ABAP Cmnds', I want to know what can be type in for that?
    and, My system is ECC6.
    thank you all

    Hello,
    Your approach (with Vijay's suggestion) MAY work.  However, depending on how tight security is at the company that you are working at you may or may not be able to acutaly change the value of the SHOW field to EDIT.  This will be especially true if you are working in a Production environment.  Vijay's other comment is true as well.  This is not a recommended approach to change data (especially data with a financial impact like TCURR) in a production environment.  The auditors will not be impressed.
    Explore the option of a maintenace view or look at tcode TBDM to upload a file which includes daily rates from providers like Reuters or try tcode s_bce_68000174 which is a maintenance view on TCURR.

  • How to save the data present in TEXT BOX?

    Hi friends i am able to create a text editor in one of my screen but i want to know how to save the data when the text is entered in that text box and retrive when they open the screen?

    Hi ,
    Please check the format below since it is based on a working code
    first you need to create a text in s010 function module...
    there should be some key based on which you plan to save the text..imagine it is Purchase order then..PO+item numner is always unique.eg:0090010(900PO/item10).so in the code you can append these two and they will be unique..so you can always retrieve them,overwrite,save them anytime you need
    **************data declarations
    TYPES: BEGIN OF TY_EDITOR,
    EDIT(254) TYPE C,
    END OF TY_EDITOR.
    data: int_line type table of tline with header line.
    data: gw_thead like thead.
    data: int_table type standard table of ty_editor.
    ****************fill header..from SO10 t-code..when you save you need the unique key..youfill it here and pass it in save_text function module
    GW_THEAD-TDNAME = loc_nam. " unique key for the text -> our unique key to identify the text
    GW_THEAD-TDID = 'ST'. " Text ID from SO10
    GW_THEAD-TDSPRAS = SY-LANGU. "current language
    GW_THEAD-TDOBJECT = 'ZXXX'. "name of the text object created in SO10
    *To Read from Container and get data to int_table
    CALL METHOD EDITOR ->GET_TEXT_AS_R3TABLE
    IMPORTING
    TABLE = int_table
    EXCEPTIONS
    ERROR_DP = 1
    ERROR_CNTL_CALL_METHOD = 2
    ERROR_DP_CREATE = 3
    POTENTIAL_DATA_LOSS = 4
    others = 5.
    IF SY-SUBRC 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
    WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    loop data from int_table and save to int_line-tdline appending it.
    *save the text
    CALL FUNCTION 'SAVE_TEXT'
    EXPORTING
    HEADER = GW_THEAD
    TABLES
    LINES = InT_LINE
    EXCEPTIONS
    ID = 1
    LANGUAGE = 2
    NAME = 3
    OBJECT = 4
    OTHERS = 5.
    IF SY-SUBRC 0.
    ENDIF.
    *To pass to Container
    CALL METHOD EDITOR ->SET_TEXT
    hope that the above sample with helps you solve the problem
    Please check and revert,

  • Dynamically built query on execution How to save the data in Object Type

    Hi,
    In pl/sql I am building and executing a query dynamically. How can I stored the output of the query in object type. I have defined the following object type and need to store the
    output of the query in it. Here is the Object Type I have
    CREATE OR REPLACE TYPE DEMO.FIRST_RECORDTYPE AS OBJECT(

    pkcounty VARCHAR2(100)
    CREATE OR REPLACE TYPE DEMO.FIRST_RECORDTYPETAB AS TABLE OF FIRST_RECORDTYPE;Here is the query generated at runtime and is inside a LOOP
    --I initialize my Object Type*
    data := new FIRST_RECORDTYPETAB();
    FOR some_cursor IN c_get_ids (username)
    LOOP
    x_context_count := x_context_count + 1;
    -- here I build the query dynamically and the same query generated is
    sql_query := 'SELECT pkid as pid ,pkname as pname,pkcity as pcity, pkcounty as pcounty FROM cities WHERE passed = <this value changes on every iteration of the cursor>'
    -- and now I need to execute the above query but need to store the output
    EXECUTE IMMEDIATE sql_query
    INTO *<I need to save the out put in the Type I defined>*
    END LOOP;
    How can I save the output of the dynamically built query in the Object Type. As I am looping so the type can have several records.
    Any help is appreciated.

    What database? Citadel, or something that has an SQL?
    If the latter, use the SQL toolkit. You can get it from NI.

  • How to save the data from AI Read.vi?

    Hi,
    The main target is that testing the strength of a object which is extended by a force. The desired results are
    1. The strength of object under the force(main target, I am trying now);
    2. Displacement of object being extended(I have mimicly done);
    3. Images of deformation of the object extended(I have mimicly done).
    4. The sub procedure will stop when the object under testing is broken. I intend to use the big pulse from force sensor by analizing the data acquired.( it is more difficult if using machine vision).
    What I am mainly trying to do now is implementation of a sub vi to collect the data which is acquired from channel 0 of PCI-6052E which is connected to a force sensor. I have tried to use an existing exam
    ple as attached with some modifications. I have tested the data from the sensor by comparing to measurement by multimeter and it takes sense. But
    1. I still don't know how to save data displayed by AI Read.vi? And use what kind data type could save more memory?
    2. I think that memory management is very important because each points of the result includes its strength, image and displacement. How can I acquire enough significant points for the final results being reliable and save these data down to an array or cluster synchronously? (each sub procedure has no time limited)
    3.Because I think that a continuous data acquisition would occupy ALL CPU TIME and their related images and displacements would have no chance to be taken down by CPU at the same moment. Am I right?--I am sure that it is not very difficult problem but my mind is still in caose and the time is quite limited to me now.
    I am looking for your sugguestion or solution or control philosophy too. You can modify the fi
    le attached if you can. I will learn from your idea.
    Thank you very much for your time and energy!

    Hello;
    Regarding your question on the data type that would use less storage space, the answer is binary type. Actually, you can use another shipping example as start point of your application. The example I'm mentioning is a data logger, that saves binary data to a file on your hard drive. You can find that example at Search Examples->I/O Interfaces->Data Acquisition->Data Logger->High Speed Data Logger.
    Regarding your question about the CPU time, the statement is valid. In case you use a synchronous AI task, the CPU execution will get stuck inside the AI Read.vi untill the buffer is ready to be read. One thing you can do about that is to change the acquisition task to be asynchronous. There is a good example in Labview showing how you can accomplish that.
    You can find the example at Search Examples->I/O Interfaces->Data Acquisition->Analog Input->DAQ Occurrences.
    You can combine both examples to accomplish the task you need.
    Hope this helps.

  • How to save the data that a user has written in a table (front panel) by using a "press button"?

    Hi,
    I have the following situation. I need to be able to save the data I write in a table (front panel) when desired.
    This allows me to modify, add new data, etc in the "Table" when wanted and to SAVE the latest information when wanted.
    I need to save all the table data by using ONLY one button.
    Thanks for the help!
    Kind regards,

    Hi,
    Thanks for the feedback. :-)
    Your answered helped.
    In this case I need to save the Data into an ARRAY.
    Now I have the following issue. I will try to explain:
    Suppose that I have following:
    1. Several GROUPS of Data like this:
        ER-1234
        ER-3245
        ER-4786
        ER-9080
    2. Each GROUP has the following ELEMENTS:
        A, Bi, Pb, Sn, Sn, Cr, Ni, Ca, ...., Al
       So it would be like
        ER-1234: A, Bi, Pb, Sn, Sn, Cr, Ni, Ca, ...., Al
        ER-3245: A, Bi, Pb, Sn, Sn, Cr, Ni, Ca, ...., Al
        ER-4786: A, Bi, Pb, Sn, Sn, Cr, Ni, Ca, ...., Al
        ER-9080: A, Bi, Pb, Sn, Sn, Cr, Ni, Ca, ...., Al
     3. An each ELEMENT has DATA that I need to save, BUT! that I need to be able to get by specifying the group and the element.
        A:
             2,3   2,4    2, 8,   2,8 
             2,2   2,3    2, 7,   2,6
             2,1   2,6    2, 6,   2,7 
             2,5   2,4    2, 5,   2,3
    How can I save the ELEMENT "A" Data with the label of the GROUP and the ELEMENT so that I can recongnize it when I need to get the DATA again?
    Thanks for the help!
    Best regards,
    Amaloa.
