Updating Multiple Rows in a DTO

I am trying the edit multiple rows. I followed the instruction in the below link.
http://www.oracle.com/technology/products/jdev/tips/mills/JSP_Multi_Row_Edits.html
But Instead of using view object i used CMP-DTO-SessionBean for my application.
I am thro till the form update. but i am not able to update the table .. Could somebody suggest me what is should do in addition to this to update my DTO which will udpate my table.
I am submitting the code below and also the code in the session bean to update one row which is working for me.
MultiRowEditAction.java

//The changes Flag
private boolean mHasChanges = false;
EjbNmpurenqLocalDTO nmpurenq = new EjbNmpurenqLocalDTO();
protected void processUpdateModel(DataActionContext actionContext)
DynaActionForm updateForm = (DynaActionForm)actionContext.getActionForm();
UpdateRowBean[] updatedRows = (UpdateRowBean[])updateForm.get("Row");
java.util.List origRows = (java.util.List)DCUtil.findSpelObject(
actionContext.getBindingContainer(),
"showPEbyParty1.rangeSet");
for (int i=0;i<origRows.size();i++ )
String theRowKey = updatedRows.getRowKeyStr();
JUCtrlValueBindingRef oldRow = (JUCtrlValueBindingRef)origRows.get(i);
if (oldRow.get(JUCtrlValueBindingRef.RANGESET_ROW_KEY_STR).equals(theRowKey))
this.updateIfRequired(oldRow,"itemrate",updatedRows[i].getitemrate());
this.updateIfRequired(oldRow,"suprmrks",updatedRows[i].getsuprmrks());
protected void validateModelUpdates(DataActionContext actionContext)
if (isDirty())
actionContext.getBindingContainer().getDataControl().validate();
setDirty(false);
private void updateIfRequired(JUCtrlValueBindingRef baseRow, String attr, String newValue)
Object baseAttrValue = baseRow.get("attr");
if ((baseAttrValue == null && (newValue == null||newValue.length() == 0))
||((baseAttrValue != null && baseAttrValue.equals(newValue))))
// no need to push the change
return;
baseRow.put(attr, newValue);

  • How to update multiple rows in one query using php

    i am new to this can any one help me how to update multiple rows at a time i am doing an school attendance page

    Often the situation is such that you have multiple courses across a range of dates.So students may take more than one course, and you need to track attendance for each course date. The following graphic demonstrates this:
    In such a situation, you need four database tables as follows:
    students (student_id, student_name, etc.)
    courses (course_id, course_name, etc.)
    students_courses (student_id, course_id)
    attendance (student_id, course_id, dater)
    A fifth table may also be needed to define the dates of courses, but you may also be able to build this array programmatically by using PHP's robust date functions, which can give you, for instance, all the Tuesdays and Thursdays between a start date and end date.
    The students_courses table simply keeps track of which students are taking which courses, so it has just two columns for the primary keys of both of the main tables. The attendance table is similar, but it also includes a date field. The following view of the attendance table demonstrates this:
    So if David's solution does cover your needs, consider yourself lucky, because this could quickly grow from a beginner-appropriate project to a moderately advanced one.

    All i want is that when users click on SUBMIT button values of point column in s_lessons(database table) be updated by new entries from user.
    i did my best and result with that code is :
    You  have an error in your SQL syntax; check the manual that corresponds to  your MySQL server version for the right syntax to use near ' lid=888,  sid=860935422, term=902' at line 1
    I would appreciate any idea.
    with prior thanks

    Go to the Row Properties, and in the Visibility tab, you have "Show or hide based on an expression". You can use this to write an expression that resolves to true if the row should be hidden, false otherwise.
    Additionally, in the Matrix properties you should take a look at the filters section, perhaps you can achieve what you wish to achieve through there by removing the unnecessary rows instead of just hiding them.
    It's only so much I can help you with the limited information. If you require further help, please provide us with more information such as what data are you displaying, what's the criteria to hiding rows, etc...

  • Update multiple rows based on two columns in same row

    I have a 1000 rows in a table I would like to update with a unique value. This unique value is a cocatenation of two columns in teh same row.
    Each row has a (i) date and a (ii) time and a (iii) date_time column. I would like to update the date_time (iii) column with a cocatenation of the (i) date and (ii) time columns.
    I know how I would update a single row but how can I update multiple rows with a cocatenation of each of the two columns - i.e put a different value into the date_time column for each row?

    Here are two ways to do this. Thanks to ranit for the table creation script, which I adapted.create table test_x
    as
    select 1 id, 'A' name, to_date('2012-12-20','yyyy-mm-dd') old_date

    USING (
      select 1 id, to_date('12/7/2012','mm/dd/yyyy') new_date
      from dual UNION ALL
      select 2 id, to_date('12/9/2012','mm/dd/yyyy') new_date
      from dual UNION ALL
      SELECT 3 ID, TO_DATE('12/5/2012','mm/dd/yyyy') NEW_DATE
      FROM DUAL
    ) n

    WHEN MATCHED THEN UPDATE SET OLD_DATE = n.NEW_DATE;Second method using UPDATE:UPDATE TEST_X SET OLD_DATE =
      CASE WHEN ID = 1 THEN TO_DATE('12/7/2012','mm/dd/yyyy')
           WHEN ID = 2 THEN TO_DATE('12/9/2012','mm/dd/yyyy')
           WHEN ID = 3 THEN TO_DATE('12/5/2012','mm/dd/yyyy')
      END
    where id between 1 and 3;
    You probably don't want to use these methods.*
    You say the "user" will enter these values. Will he always enter exactly 3 values?
    The "user" will enter values into a screen I suppose. What language is the user interface programmed in?

  • BC4J datagrid to update multiple rows

    Hi,
    How do we update multiple rows at a time in a BC4J JSP with Struts. I intend to have a datagrid control on a JSP so that users may update multiple rows at a time and click 'Update' once.
    There is a possible (workaround) solution using struts nested tags but one would lose the benefits of JBO tags on using struts tags (e.g Calendar control would not be visible for Date input).
    Any implementation suggestions?

    Ashish

    Does the database only contain data where there are events on a given 15-minute time slot?

  • Update Multiple Rows using Row Selector

    Hi,
    I want to update multiple rows using a tabular form with row selector, and an item in another region of the page, using an update expression and a button.
    The syntax would be like this:
    update MY_TABLE set UPDATABLE_COLUMN = :P10_NEW_VALUE where {row selector = true}
    What is the syntax for the WHERE clause, anyone knows? In the manual there is no information at all for doing this.
    PD. I added the row selector after creating the form, so I don't have any wizard-created MRU processes in the page.
    HTMLDB version is 1.6

  • Updating multiple rows in a table in ADF

    Hi
    How do we update multiple rows in a table.
    Onclicking a update button the changed rows must be updated.

    Hi Prince,
    currently I am selecting one row from the table and rendering a region at the top of the table and capturing the user entered data with the following code:
    ViewObjectVOImpl vo = getViewObjectVO1();
    Row CurrentRow = vo.getCurrentRow();
    //After this I perform the checks like user entered value is not null or check input as per business logic.
    if(CurrentRow.getAttribute("attributeName") ==null){
    //Add what message you want to display
    //Add other business logic.
    After making all the checks, i commit it.
    getOADBTransaction().commit();
    Now in my new page I am capturing the user input in the table itself like an excel sheet. Suppose there are ten rows in my advanced table on my page, and each row has one editable field. I have one save button at the bottom of the table.
    Now on clicking the save button I have to capture the user input, check whether there is any null value and if all the entered data is correct then only I should commit it.
    Can you please let me know how we can accomplish that.

  • Updating multiple rows with different values

    Hi!
    I have a problem. I need to update more then 1000 rows with different values. How can I do it?
    For exsample i have table:
    id; color, date,
    1 red
    2 green
    3 white
    I need to update date field.
    Update table
    set date='01.02.03'
    where id=1
    Update table
    set date='01.03.03'
    where id=2
    Maybe there is way how to update multiple rows at one query?
    Sorry for my bad english.
    Thanks!

    Hi,
    You can try this
    UPDATE TABLE SET DATE = CASE
                        WHEN ID = 1 THEN TO_DATE('01-02-03','DD-MM-RR')
                        WHEN ID = 2 THEN TO_DATE('01-03-03','DD-MM-RR')
                        ENDcheers

  • Trouble updating multiple rows in table using subquery

    Hi everyone, I'm having trouble updating multiple rows with a subquery. Here's the setup:
    create table mytable (
    col_a number primary key,
    col_b number,
    col_c number,
    col_d number);
    insert into mytable values (1 ,1,1,15);
    insert into mytable values (2 ,1,2,7 );
    insert into mytable values (3 ,1,3,11);
    insert into mytable values (4 ,1,4,23);
    insert into mytable values (5 ,1,5,14);
    insert into mytable values (6 ,2,1,50);
    insert into mytable values (7 ,2,2,41);
    insert into mytable values (8 ,2,3,13);
    insert into mytable values (9 ,2,4,12);
    insert into mytable values (10,2,5,19);
    insert into mytable values (11,3,1,10);
    insert into mytable values (12,3,2,92);
    insert into mytable values (13,3,3,81);
    insert into mytable values (14,3,4,17);
    insert into mytable values (15,3,5,66);
    insert into mytable values (16,4,1,54);
    insert into mytable values (17,4,2,41);
    insert into mytable values (18,4,3,22);
    insert into mytable values (19,4,4,24);
    insert into mytable values (20,4,5,17);For this example, using an update statement (or merge if that's better), say I want to set the values for col_d where col_b = 3 equal to the values for col_d where col_b = 1 and col_c equal each other. Results should look like the following after the update:
    col_a col_b col_c col_d
    1     1     1     15
    2     1     2     7
    3     1     3     11
    4     1     4     23
    5     1     5     14

    18    4     3     22
    19    4     4     24
    20    4     5     17I can see it right there at my fingertips using this query, where I want to set b_col_d = a_col_d, but I'm missing something, as this query returns too many rows when used in the update statement.
    select * from (
      select col_a as a_col_a, col_b as a_col_b, col_c as a_col_c, col_d as a_col_d
      from mytable
      where col_b = 1
      ) a, (
      select col_a as b_col_a, col_b as b_col_b, col_c as b_col_c, col_d as b_col_d
      from mytable
      where col_b = 3
      ) b
    where a.a_col_c = b.b_col_cupdate mytable set column_d = (select ??? where exists ???)
    Can someone help me get there? I'm using 10GR2.

  • CMP update multiple rows

    Hi,
    Is there a way to update multiple rows when using CMPs.
    For example I can update multiple rows by this method.
    while (condition)
    cmp = cmpHome.findByPrimaryKey(key);
    cmp.setValue(newValue);
    Rather than this method is there a way that I can update many rows just as normal sql update.
    thanks in advance,
    chamal.

    If you want to concatenate Acol column with sysdate for 605 and 608 ....i think you need to code less (of what you have posted)
    UPDATE TEST
    SET TEST.ACOL =  TEST.ACOL || ' ' ||sysdate
    where
    test.acol in (605,608);--I don't know why you want this , Just given the suggestion as per the requirement.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           

  • Update multiple rows involving spatial data

    Hi,

    Thanks

    Hadi,
    There are a number of things wrong with the second item. First up you most likely will return more than one row, which is not allowed as the = expects only one item.
    Here is what I would use, which will update everything that meets the requirements, and ignore the rest:
    UPDATE (
    SELECT /*+ bypass_ujvc */
    state, store_id, store_state
    FROM temp, us_states
    WHERE sdo_inside(temp.geom, us_states.geom) = 'TRUE')
    SET store_state = state;
    With the /*+ bypass_ujvc */ you're telling the db to not worry about requiring a "unique join view condition" -- which roughly mean "trust me, my rows are key preserved." This is important since there is really no "hard" key-based relationship to tie the two together.
    However, unless you really think there are stores that border on two states, this will run much quicker with an anyinteract comparison.

  • Want to update multiple rows of the report but getting a bug.

    hi,
    I am trying to update multiple rows of a report.For that I have created a teport with dynamic checkbox generated using ---HTMLDB_ITEM.CHECKBOX(1,utt.trouble_ticket_id) " "----.Checkboxes are rendered perfectly on the report.
    but when I tried to update the selected rows of the report as given in the documentation
    begin
    :P16_priority:=htmldb_application.G_F01.count;
    for i in 1..htmldb_application.G_F01.count
    loop
    update umanage_trouble_ticket set severity =:P16_priority where
    trouble_ticket_id = htmldb_application.G_F01(i);
    end loop;     
    end;
    I found that all the rows are updated.not only selected rows.
    and the count it gives =no of rows returned + no of rows selected.
    Please help me regarding this.
    thanx.
    BHARAT

    Hi Bernhard,
    I think that u didnt get y problem.
    When I take the value from "htmldb_application.g_f01(i)" then it should return id's of rows that are checked but when I do that it returns id's of all the rows.So I am not able to update only checked rows.
    from id's of rows i mean value provided when generating checkboxes through query.
    htmldb_item.checkbox(1,trouble_ticket_id) " "
    I am approching to the solution as specified in the documentation. "Adding check boxes to each row in a report".
    but still cant find any solution.
    thanx that u showed some intrest in my problem.
    If u can get the solution reply soon.
    Regards

  • Updating Multiple Rows With A Sequence

    I'm trying to update multiple rows of data in one column based on if its date is greater than a certain date. Starting with the lowest date from those dates I'll give it a 2000 and every ascending date from that point will be another number in sequence (2001, 2002, 2003, etc.).

    I would use a counter and start at a specific number. Then I would try to keep updating with this number and incrementing each time. The part I can't quite grasp is how to use this number with the lowest record and apply this sequence to each date that ascends from there. What I was going to try to come up with is something like:
    DECLARE
    counter := 2000;
    BEGIN
    loop
    update table_name
    set column_name = counter
    where date > specified date;
    counter := counter + 1;
    end loop;
    This is my first thought but I couldn't see a way to just update the first one that is greater than the specified date and then keep cycling through the dates until the last date(most recent). I know I would need a loop but what can I set that loop to so it would know when to stop. I could use a variable I know is less than the total amount that need to be altered.
