Management key id primary auto increment without using triggers
Hi, we have a lot of table in our database with the installation of key ID primary autoincrement than they are in MySQL since we are in the process of migrating to Oracle of MySQL. Now in oracle I learned recently that this application requires the creation of a sequence and a trigger on the id for each table in the type field. We have tables of 30-40 in our scheme and we want to avoid the use of database triggers in our product, as the management of database is out of reach for our device software.What are my options to implement the auto increment id feature in oracle... aside from manually specifying the id in the code and it management in the code that would change many existing insert statements. Some info about our application environment: groovy grails, hibernate, oracle, support for mysql
It is NOT auto-increment, you can avoid manual entry. When executing the INSERT statement, you must use the value of the sequence.

Hi all
for the moment, we are on 11.1.2.1 and one more late upgrade scheduled to 11.1.2.3, use Calc Manager rather than the rules Business (EAS). Therefore, I would like to upgrade to business at Calc Manager rules, but without using EPMA (we would still use the classic Planning Administration). I read several documents and sites, but I was unable to find a way to do... Does anyone have a how or documentation about my problem?
Thank you very much
André
P.S.: Maybe to make it a bit clearer: I won't spend 11.1.2.1 to 11.1.2.2. I would only use Calc Manager instead of business EAS rules 11.1.2.1 and I couldn't find anything that shows how or if it is possible to migrate from the business rules to Calc Manager (without using EPMA).
You can change the method of calculation of the Manager of Calc application. I replied to your message in the Manager area of Calc.

No sequences present in the comparison of two models of auto-increment columns and triggers

Thank you
Hello
No DOF preview is currently generated differences in properties on the auto-increment columns properties page.
However, if you create a sequence with the relevant name (and the user as appropriate) in your physical model Oracle, then its properties will be used instead of the ones on the page Auto Increment, and in this case the DOF preview will include the DDL for changes in its properties, e.g.
FALL OF SEQUENCE "TABLE_1_SEQ".
;
CREATE SEQUENCES "TABLE_1_SEQ."
START WITH 5
INCREMENT OF 10
;
If only the increment "by" is changed, an ALTER SEQUENCE will be generated:
CHANGE THE SEQUENCE "TABLE_1_SEQ".
INCREMENT OF 10

Published by: 841780 on March 4, 2011 04:41Change your cursor for select payroll_id, time_period_id, period_num and remove the "updates". If none of those are the primary key, select the primary key as well. Then set a variable to periods_to_go (payroll_id, time_period_id, period_num), then update the table set nom_de_variable = attribute20 where primary_key = cursor_name.primary_key.

Update field of auto-increment using ASP.
I use Dreamweaver 3 and created dynamic arrays using the tools ASP. I met a wall:
When you create a form to a form, how to configure the form to update an Auto-Increment field in Access?
I have what I think is a good book on Dreamweaver, but this feature is not discussed. If I omit the field of
the form, he leaves the null field and I get a database error, as I expect.
Any help or documentation links will be appreciated.
Joe
As others have said, the database must manage this area and it shouldn't appear on the form on the page in code that performs the actual insertion or update.
Do you a little differently depending on whether you use the wizard insert or create the form by hand and then apply the server behavior insert.
If you use the wizard when you select the fields in the form, make sure that you click the auto increment field, and then click the icon 'less', this it will remove the form and it will not appear in the code generated automatically, leaving MS Access free to manipulate himself.
If you create the form by hand, do not include a form for the field to auto-increment element, then when you apply the Insert behavior it will not appear in the code generated automatically, leaving MS Access free to deal with himself.

No start page, Google rises and there is no way out without using the Task Manager.
I used to get the Google search engine at the start of Firefox, with bookmarks bar in side bars and tool at the top. Now, all I get is a Google search page, with a few buttons on the top like images, etc. There is no way to close the program without using the Task Manager. I downloaded the latest version of Firefox and installed, but the problem has not disappeared. Operating system is Windows XP Professional
Make sure that you run not Firefox mode full screen (press F11 or Fn + F11 to toggle; Mac: Ctrl + Shift + F).
It is possible that the screen is too wide or too high and bars scrolling down.
- Use Restore or expand in the context menu of the taskbar icon to set the focus to the Firefox application if you do not see the window of Firefox.
- Open the system menu of the window of Firefox via Alt + space and see if you can move and resize the window (use the arrows on the keyboard).
If it works, then first close all other open windows of Firefox and then close Firefox via "file > exit/Quit" to save the setting.

A week ago, I unplugged my external Seagate USB drive without using a 'Remove hardware safely' first of my Vista pc. Since reconnecting the drive, I had a series of problems. The drive itself seems to be ok. I am able to read and write to files on the disk. I'm not able to do is the following:
(1) open disk management. It hangs on "Connecting to Virtual Disk Service".
(2) stopping or starting without windows to snap or take an extra long time to stop or start.
(3) failed to start Google Picasa3 or Adoble Photoshop Elements 7. They both hang him. I am able to use other programs such as Microsoft Office, Outlook, Miro, Norton Antivirus.
Points 1 and 2 above work fine if the drive is not connected. I plugged the drive into another computer (Windows 7) and ran Seagate disk checking utility. He came clean back (no bad sectors) so that the drive is NOT corrupted. (Check of the Seagate utility disk hung on my pc Vista.) It seems that something related to the disk under Vista service is corrupted.
I also see "driver has detected an error in the controller on \Device\Harddisk2\DR2." event message for different devices. I also tried a restore to a point just before that the problem occurred.
I don't want to reinstall Vista therefore looking for a solution. Thank you.

Maybe not ideal for designing this, but you can use something like this:
BindingContext bindingctx = BindingContext.getCurrent();
BindingContainer bindings = bindingctx.getCurrentBindingsEntry();
DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
DCIteratorBinding dciter = bindingsImpl.findIteratorBinding("DepartmentsView1Iterator");
ViewObject vo =dciter.getViewObject();
vo.setNamedWhereClauseParam("myDepId",AnyValue);//enter your value
vo.executeQuery(); -

Extracting data from table without refreshment and without using the tab key.
Hi friends,
I have a problem I want to extract data from table without discount in the text field without using the Tab key. When I enter a field value any value then the text corressponding should enter into corressponding textfield without using the Tab key.
for example. When I get back emp_id 101 in a text field then first_name and last_name, address would come in to the text fields corressponding without refresh and use the Tab key.
How can I do that.
Thank you
MauryHi Maury,
I guess it's similar to: retrieving data without refreshing rather than Re: value of a textfield should enter into an another textfield without using the TAB ?
If so, the only change you want to bring on the first is to use the parameter "Onkeyup" instead of "onchange" in the 'HTML Form attributes of the element' element.
Note, however, that the user must move away from the issue at some point (for example, to click on a button), so the onchange will fire anyway.

mobile device of auto incremented field
Hello
my colleague needs to establish a mechanism in the mobile device (client lite oracle) where the primary field of a table is automatically incremented.
According to the documentation in order to make that happen consistently, so that all customers can synchronize correctly without ambiguities, we have created a sequence
through the MDW and attached to the publication. then with synchronization, this sequence has been downloaded to all customers and each has a specified window.
We assume now that we must create the trigger that uses this sequence to provide the correct primary key field.
lets say that the sequence is SYSTEM names. AUTOINCSEQUENCEA
the table is named SYSTEM. TABLEA
and the primary key we want auto incr is named ID.
the trigger that we assume that should look like:
CREATE A TRIGGER SYSTEM. TRIGGERTABLEA
BEFORE INSERTING
ON THE SYSTEM. TABLEA REFERENCING NEW AS OLD new AND old
FOR EACH LINE
BEGIN
Select AUTOINCSEQUENCEA.nextval in: double new.ID;
END;
(1) but if I run this from the msql on the client machine (windows mobile device) returns an error "syntax". How can I create the trigger that I need that uses my sequence in order
to appoint the new values in the primary key (auto incremented field?).
(2) if I can't make it through a normal sql statement then how can I do?
Thank youFinally got the work in the sample. See the example:

I am trying to create a development machine, where we can test the new code without using our physical hardware. I followed this guide to set up a system of simulation. I get to step 3.2 b, but the device does not appear in the DAQ assistant. MAX, the device self test and gites calibrated successfully, and when I open the test panels, I see some sort of signal. I guess that's a default entry simulated since I didn't that device to look for anything? Note that two devices, I am creating the show upward into the devices section and Interfaces, but that, even after running auto calibrate, automatic Calibration date is not yet specified.
When I try to test the device and create a voltage according to the guide, I can't see a device in the creator of data acquisition task.
Steps 1 and 2 of this guide are of course met. Step 3 is not, but this is not surprising because a simulated device is in device in any case manager. Also, I'm not under RT, so step 4 is satisfied.
Someone at - it ideas?
That would be because the PXI-5124 is a digitizer not an analog input device. You must use the NI SCOPE not NOR DAQmx driver
