How can i programatically update row

hi All,
i have created a AgencyApproval view object that contains attribute like(agencycode,approve_status,approve_by,approve_hier)
i have drag drop this vo as ADF table and select only agencycode and approve_status and not select approve_by and approve_hier field.
now i want when i update approve_status filed and press commit button approve_by field value programatically handle. and update.
by default approve_by column contain 'nul' but when i change into approve_status field that contain previous value'N' to 'A'l

You already did it.
protected void prepareForDML(int i, TransactionEvent aTransactionEvent)
            if (i != EntityImpl.DML_DELETE)
                     ViewObjectImpl vo = (ViewObjectImpl)this.getDBTransaction().findViewObject("payemptaskVo");
                     Row row = vo.first();// assumed that the data you want to access exist in the first row
                     setAttribute ("hier", row.getAttribute("hierarchy");
                   super.prepareForDML(i, aTransactionEvent);
        }

How can I use multiple row insert or update into DB in JSP?

Hi all,
pls help for my question.
"How can I use multiple rows insert or update into DB in JSP?"
I mean I will insert or update the multiple records like grid component. All the data I enter will go into the DB.
With thanks,

That isn't true. Different SQL databases have
different capabilities and use different syntax, That's true - every database has its own quirks and extensions. No disagreement there. But they all follow ANSI SQL for CRUD operations. Since the OP said they wanted to do INSERTs and UPDATEs in batches, I assumed that ANSI SQL was sufficient.
I'd argue that it's best to use ANSI SQL as much as possible, especially if you want your JDBC code to be portable between databases.
and there are also a lot of different ways of talking to
SQL databases that are possible in JSP, from using
plain old java.sql.* in scriptlets to using the
jstlsql taglib. I've done maintenance on both, and
they are as different as night and day.Right, because you don't maintain JSP and Java classes the same way. No news there. Both java.sql and JSTL sql taglib are both based on SQL and JDBC. Same difference, except that one uses tags and the other doesn't. Both are Java JDBC code in the end.
Well, sure. As long as you only want to update rows
with the same value in column 2. I had the impression
he wanted to update a whole table. If he only meant
update all rows with the same value in a given column
with the same value, that's trivial. All updates do
that. But as far as I know there's know way to update
more than one row where the values are different.I used this as an example to demonstrate that it's possible to UPDATE more than one row at a time. If I have 1,000 rows, and each one is a separate UPDATE statement that's unique from all the others, I guess I'd have to write 1,000 UPDATE statements. It's possible to have them all either succeed or fail as a single unit of work. I'm pointing out transaction, because they weren't coming up in the discussion.
Unless you're using MySQL, for instance. I only have
experience with MySQL and M$ SQL Server, so I don't
know what PostgreSQL, Oracle, Sybase, DB2 and all the
rest are capable of, but I know for sure that MySQL
can insert multiple rows while SQL Server can't (or at
least I've never seen the syntax for doing it if it
does).Right, but this syntax seems to be specific to MySQL The moment you use it, you're locked into MySQL. There are other ways to accomplish the same thing with ANSI SQL.
Don't assume that all SQL databases are the same.
They're not, and it can really screw you up badly if
you assume you can deploy a project you've developed
with one database in an environment where you have to
use a different one. Even different versions of the
same database can have huge differences. I recommend
you get a copy of the O'Reilly book, SQL in a
Nutshell. It covers the most common DBMSes and does a
good job of pointing out the differences.Yes, I understand that.
It's funny that you're telling me not to assume that all SQL databases are the same. You're the one who's proposing that the OP use a MySQL-specific extension.
I haven't looked at the MySQL docs to find out how the syntax you're suggesting works. What if one value set INSERT succeeds and the next one fails? Does MySQL roll back the successful INSERT? Is the unit of work under the JDBC driver's control with autoCommit?
The OP is free to follow your suggestion. I'm pointing out that there are transactions for units of work and ANSI SQL ways to accomplish the same thing.

How to find newly updated rows in a table

Hi..
How to know newly updated rows in a table.
Thanks in advance
pal

Or other good thing would be to add LAST_UPDATED column to your table, that can reflect the time the row gets updated.

How can I label my rows on numbers so I can keep a running count? Dave

How can I label my rows on numbers so I can keep a running count?
i would like to number from 1 to 150 by highlighting and use a function command
Dave
               Name               Address          Email
Ex      1
          2
          3
          4
          150

Add a column to the left of column A (it will become column A).
Assuming you want to start with the first "name" in Row 2 (and NOT number the header row):
Two methods:
1.
In cell A2, enter =ROW()-1
Grab the Fill Handle (small circle, bottom right of the selected cell) and drag down to fil the formula into the rest of the cells in the column.
If the formula is placed in ALL non-header row cells in the column, it will automatically fill into any rows added to the table.
If rows are inserted or removed, numbers below the inserted/removed row will be automatically adjusted.
2.
In cell A2, enter a 1
In cell A3, enter a 2
Select both cells.
Grab the Fill Handle and drag down to the rest of the cells in the column.
These are fixed numbers. They will not be automatically filled into new rows added to the table, nor will they automatically update when rows are inserted into the table or removed from the table.
To add more numbers, select the last two cells currently containing numbers, drag the Fill Handle down.
Regards,
Barry

How can I programatically identify PDF files with embedded images?

Our company has 27,266,949 .PDF files that we're planning to compress in order to save server space.
We don't want to compress any of the .PDF files that have embedded images as to not alter the image's state.
How can we programatically create a list to exclude from the compression process?

Ah, see told you we were new to this and no, my taxs already have enough digits to the balance.
Ok, so based on that, we should be able to use the preflighting tool to identify the PDF’s with images, factor them out, and then continue with lossless compression on the remaining balance.
That will give us the compression we need to save space, but also allow us to stand in the court of law (if the scenario was to ever occur) and proclaim that none of our medical images have ever been altered by compression.
Sound like a reasonable plan?

HT1338 i have apps to be updated but when i try to update them a message pops out saying "You have updates for other accounts, please sigh in with the other id". Can some one help me how can i still update the same with the new apple id ive created.

i have apps to be updated but when i try to update them a message pops out saying "You have updates for other accounts, please sigh in with the other id". Can some one help me how can i still update the same with the new apple id ive created. As i dont have the access to the earlier id anymore.

You cannot. The apps are assigned to that Apple ID and there is nothing you can do to change that. You could choose to download them again with the new Apple ID, any paid apps will need to be purchased again.
Hope that helps.

How can I remove updates from my I-pad

How can I remove updates from my I pad

What updates ?
If you mean from the Updates tab in the App Store app then you can't - any updates that you've downloaded will disappear off that last in 30 days. If you don't want to install an app update then as far as I know they can't be removed from the Updates tab.
If you want to got back to a previous version of an app then do you have a copy of that previous version anywhere ? If you do then you can delete the app from your iPad (which will also delete its content) and sync back the previous version.
If you mean an iOS update that you've installed then you can't, downgrading the iOS version isn't supported by Apple.

How can I add a row into a JTable with JButton

Hi all. I have the following code:

    private String columnNames[] = {"�� ", "��", "��", "��", "��", "��",

    private ArrayList data;
    public FoundersTable(){
        data = new ArrayList();
    public int getRowCount() {
        return data.size();
    public int getColumnCount() {
        return columnNames.length;
    public String getColumnName(int colIndex) {
        return columnNames[colIndex];
    public Object getValueAt(int rowIndex, int columnIndex) {
        return ((ArrayList)data.get(rowIndex)).get(columnIndex);
    public void setValueAt(Object value, int rowIndex, int columnIndex) {

        data.remove(index);
        fireTableRowsDeleted(index, index);

        data.clear();
        fireTableRowsDeleted(0, 0);
    public boolean isCellEditable(int rowIndex, int columnIndex) {
        return true;
}Now in my MainJFrame class I have one button for additing and one button for removing a selected row. How can I add/remove rows with this two buttons.
Thanks

No my question is how can I add and remove rows WITH buttons My point was the code is the same. You use the addRow(...) method. Why did you write an addRow(...) method if you aren't going to use it?
I don't understand your problem. Do you not know how to write an ActionListener?

I bought pages ages ago using an iTunes account that no longer works as the email address has been closed down. How can I now update my Pages app, if it asks me to sign in using this now defunct email address?

I bought Pages ages ago using an iTunes account that no longer works as the email address has been closed down. How can I now update my Pages app, if it asks me to sign in using this now defunct email address?

All apps are always tied to the account from whaich they were purchased and will always have to be updated using that account.
Just because the e-mail account is shut down, has nothing to do with the itunes account. Why did you create a new account? Why not just change the e-mail associated with the old account?

Thanks - I tried to with my new Apple ID - as I had to update the software, although it warned me I'd lose content on my iPad. But I did the update, it took 30 minutes, but then did not work, as my iPad still has the older version of the software. What went wrong there?

How can I control updating in Oracle ADF

I have been using Oracle Forms for many years and am trying to learn Jdeveloper and Oracle ADF. In Oracle Forms, we base all of out blocks on views and control all updating in on-insert, on-update, and on-delete triggers. How can I control updating in Oracle ADF in a similar manner?

ADF 7 wrote:
SELECT * FROM Table WHERE lastupdTimestamp = (SELECT MAX(lastupdTimestamp) FROM Table)lastupdtimestamp - holds and date an time of an records when it last updation takes place in table.
lastupdtimestamp is a column in my table.And how will this make sense in the scenario I've described, where UserA does an update before UserB, but commits the update after UserB's commited update? And add UserC and UserD and a 1000 more users to this scenario where concurrent updates happen.
What actual time does this lastupdtimestamp contain and represent? And why? How is that lastupdtimestamp used in business logic and processing? Or is it just a silly-bugger-let's-add-somekind-of-time column to that table that essentially meaningless?
Not saying that one should never add such a timestamp based column. Simply that one needs to understand WHAT it contains and it needs to be SENSIBLY used within the data model.
However, in my experience such columns are often slapped on afterwards, never featured in the actual data model designed, and is then used without a second though that the database and its data is a multi-user and multi-process system. And things happen at the same time. And things overlap (serialisation is the exception - not the rule).

How can I add new row/column into existing jTable?

Hi add!
Can you help me how can I add new row/column into existing jTable?
Tnx in adv!

e.g
Create two buttons inside the Table ( "Add New Row" ) and ("Add new Column")
their handlers are:
add new row:
//i supose u already have
DefaultTabelModel tablemodel = new DefaultTableModel(rowdata, columnNames);
//and
   JTabel jtable = new JTable(tablemodel);
// Handler (row)
jbtAddRow.addActionListener(new ActionListener(){
   public void actionPerformed(ActionEvent e) {
      if(jtable.getSelectedRow() >= 0 )
          tablemodel.insertRow(jtable.getSelectedRow(), new java.util.Vector());
       else
            tablemodel.addRow(new java.util.Vector());
    });to add new columns its the same but inside actionPerformed method:
ask for e.g "Whats the name for the new column"
then,
   tablemodel.addColumn(nameOfColumn, new java.util.Vector());   Joao
