How to lock a specific record

Let’s say I need to lock a specific record from a form so nobody could even select this record from database.
How do I do this?
Thank you in advance

Add a default_where property for your block that will eliminate this record from being selected.
For example:
set_block_property('emp','default_where','ename!='SCOTT');

Does anyone know how to lock a specific application, such as e-mail in Ipad?

I have my company email in my Ipad and I want to lock it in order to prevent whoever uses my Ipad to login to my email. Does anyone know how to lock a specific application or it cannot be locked?

There is a somewhat clunky way to do it. First, go into your mail (Settings - Mail/Contacts/Calendars) and turn off (dont' disable) any accounts you don't want to be seen. Then go into Restrictions - Accounts and select "Don't Allow Changes." This will prevent anyone from turning the mail back on. When you're ready to turn it back on, go into Restrictions and either Disable Restrictions or go into Accounts and select Allow Changes.

How can I update specific records in a tabular form

I have a form with two blocks. One is a "simple form" and the other block is "tabular".
In the "tabular form" I have some data (codigo, descripcion, importe)
I want to update the item "importe" acording to specific values given in the "simple form". What I don4t know how to do is tell the form which record I want to update.
Hope to be clear.
Versnica

Versnica,
as i understood u got two blocks and u need to update that record in second block which value matches to block one .
eg
u can "A" item in values "Value1" in block 1 and there is record in block two with item "B" has same value "Value1". then u can use
procedures like NAME_IN(<<item A>>) = NAME_IN(<<item B>>) then update the record in second block .
see whether it helps for not ? otherwise u can send me forms on [email protected] so that i can have a look .

How to lock a table/record from being read

Hi,
We are facing a problem executing a backend operation due to the presence of 2 JVMs.
We have a set of batch jobs that needs to run on a daily basis. We are using a flag in a table to check if any job is currently running, based on which the job is kicked off.
The problem comes up when the 2nd JVM tries to read the same data present in the table and kicks off the job, which it shouldnt.
Currently this is how i am implementing it:
SELECT COUNT(1) into l_status FROM Log_Table
where job_status is NULL
FOR UPDATE;
IF (l_status = 1) THEN
UPDATE Log_Table
SET Job_Status = 'In_Execution'
WHERE Job_status = NULL; -- Only 1 rec will contain this field as NULL
END IF;
COMMIT;
l_status decides whether the job should run or not.
SELECT..FOR UPDATE does not stop the 2nd JVM from reading the data (or will it?). The 2nd JVM will just wait for the lock to be released, execute the UPDATE without knowing the current value of Job_Status and then start the batch job. Correct me if my knowledge of SELECT FOR UPDATE is wrong.
What can be done to completely avoid the 2nd JVM from intervening?
Solutions would be much appreciated.

I have dealed with your problem. Please checkout thread Is it possible to pevent select operation on a table?

How to lock a specific map with a password in FINDER?

I don't use a password on my mac because you have to fill it out the whole time for ridiculous reasons. But I have one map, with all my financial numbers and invoices, that I want to secure with a password.
How to do that?
I already tried some things but can't figure it out.
Thanks in advance!

not sure what you mean by a map here. if you use a blank admin password (a mistake IMO), pretty much your only option is to create an encrypted disk image using disk utility and put whatever you want protected inside. when the image is unmounted, the only way to mount it is by entering the password you set at the image creation time.

How to Copy the specific record of one table to other table(same structure)

Hello,
i have develop a form and some buttons on it. Suppose that Form is based on TABLE_1, which has the fiollowing structure.
( Bill_No Number(5),
Bill_Date Date,
Bill_amount Number(6),
Description Varchar2(60)
My requirement is when i save the any record and after that i want to copy all the contents of that record to Table_2.
On the form there is a button named as Let say "Copy current Record to Table_2". So when i press the button, the record is copied from Table_1 to Table_2.
(Note: - Table_2 has the same structure as Table_1.)
Please help me to solve this problem.
Thanks in advance.

i would prefer a pure database-solution, means put a database-trigger BEFORE INSERT FOR REACH ROW on your table 1 and do the insert there.
If you do it in PRE-INSERT-Trigger in forms it will work for data entered via forms-application, but what happens if data is inserted via a different frontend?
CREATE OR REPLACE TRIGGER TRG_TABLENAME_BRI
BEFORE INSERT
ON TABLENAME
FOR EACH ROW
BEGIN
-- Do your insert here
INSERT INTO TABLE2 (
    COL1,
    COL2
) VALUES (
    :NEW.COL1, -- (or OLD.COL1)
    :NEW.COL2 -- (or OLD.COL2)
END;

How to display/navigate to specific record in a table with more then thousand records

Hi,
there is a task that I do not know how can be resolved.
There is a query that returns around 1 - 2 thousand records. And all those records have corresponding weight assigned.
After query executing it is necessary to navigate to the records with the highest weight assigned. It can be first record, it can be a record at the end or in the middle of the row set from thousand records.
I have used "DisplayRow"=selected or the code below, but it does not work properly ... when the record that we navigate is in the middle of record set from 2000 records, then users have to scroll down to it.
And I need to position to that specific record after query is executed.
So I used the code below:
public void onButtonClicked(ActionEvent actionEvent) {
DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iterator = bc.findIteratorBinding("ViewVIIterator");
        Row row = iterator.getCurrentRow();
        String bestPosition = (String)row.getAttribute("BestPosition");
        iterator = bc.findIteratorBinding("DetaillVIIterator");
        ViewObject vo = iterator.getViewObject();
        vo.setWhereClause(some_conditions);
        vo.executeQuery();
        RowSetIterator rowSet = iterator.getRowSetIterator();
        Key key = null;
        while (rowSet.hasNext()) {
            row = rowSet.next();
            if (row != null && ((String)row.getAttribute("weight")).equals(bestPosition)) {
                key = row.getKey();
                Key rowKey = row.getKey();
                ArrayList tableRowKey = new ArrayList();
                tableRowKey.add(rowKey);
                this.getRangeTable().setScrollTopRowKey(tableRowKey);
                break;
After the code above I getting the row selected or set as a current, but in case of 2000 records, when my record is in the middle of this record set, I need to scroll down to this record to see it.
And I wanted that I will be navigated to my record with records above and below.
What am I doing wrong above?
Thanks
Alexander

Hi Timo!
thanks for the reply.
version info:
Oracle JDeveloper 11g Release 2 11.1.2.3.0
Studio Edition Version 11.1.2.3.0

1. sorting order is already applied and we to position to a specific record in af:table.
From another side the task can rephrased: I need to position to a specific record and I need to be able to show 500 records before and 500 records after.
So where clause can be like:
:bestPosition > position - 500 and :bestPosition < position +500.
2. I tried to apply your second approach and found that record is selected, but I need to scroll to it down. It happens when first 20 records are displayed in af:table and my record is 480 records below ...

I'm not sure what's happening with your app. I wrote on up to see if it could handle the CTRL-C. Seems to work fine. Do you have any other JMenuItems with the same accelerator?
import java.awt.event.*;

public class Copy extends JFrame {
     public Copy() {
          this.initMenuBar();
          this.setSize(400, 300);

          this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     private void initMenuBar() {
          JMenuBar menubar = new JMenuBar();
          JMenu edit = new JMenu("Edit");
          JMenuItem copy = new JMenuItem(new CopyAction("Copy"));
          edit.setMnemonic(KeyEvent.VK_E);
          copy.setMnemonic(KeyEvent.VK_C);
          copy.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_C, InputEvent.CTRL_MASK));
          edit.add(copy);
          menubar.add(edit);

So, is there any method to solve it?
Thanks a lot.
