How to use the trigger to back up the line to another table before update?

I have this table to save the password.

SQL > create table passwd_inv
2 (username varchar (10),)
3 password varchar (10),
4 insert_date date default sysdate);

Table created.

I have this table as a historical table.

SQL > create table passwd_inv_bkup as (select * from passwd_inv);

Table created.

SQL >

SQL > insert into passwd_inv
2 (username, password) values ('scott', 'tiger');

1 line of creation.

SQL > commit;

Validation complete.

SQL > select * from passwd_inv;

USERNAME PASSWORD INSERT_DA
---------- ---------- ---------
March 31, 12 Scott Tiger

SQL >


If I try to update the password for 'scott', in an ideal world, the old value (the entire row) must be safeguarded (insert) of passwd_inv_bkup?


Thank you very much.
create or replace trigger T_PASSWD_INV_BUPADTE
  before update of PASSWORD on PASSWD_INV
  for each row
begin
   insert into PASSWD_INV_BKUP
     (username, password, insert_date)
   values
     (:old.username, :old.password, sysdate);
end T_PASSWD_INV_BUPADTE;

  • How to use the capture and the print button

    I tried to figure out how to use the capture and the "print" button, or add or what you call. I press it and the whole page of a different color changes, so I try to cut the section I want but I don't know how to send it to the printer. Can someone help me with this. I'm not at savvy with tech stuff, but when I find a recipe or something and it doesn't have an option to print a certain area, I can't understand how to use it?

    Thank you

    Andi Starbuck

    That happens to me is, I click and drag to make a rectangle of yellow selection, and as soon as I raise my finger on the mouse button, the part I've selected is captured as an image, a new tab opens and preview before printing, the image display. I can use the installation of the Page or simply print. But if I close the preview, this temporary image vanishes and I'm back on the page where I started. You see something different?

  • Satellite M300 - how to use the recovery disk

    Hello world

    I was wondering how to use the 2 recovery discs that I burned recently if I wanted to fix my USB ports (as seen in my Toshiba M300 - wire to USB ports)

    Any suggestions?

    Hello

    You can use the only recovery disk to reinstall the whole OS!
    This means that the use of the recovery disk will format the whole HARD drive and will set the laptop back to factory settings!

    If you want to use the recovery disk and then insert it into the ODD and the start-up of this disc.
    Then the installation of the OS should move forward and you should follow the instructions on the screen.

  • Pavilion dm4-3090se: how to use the SSD after restoration of the system of Windows backup disks?

    Hello

    After a lot of work, I finally could restore my OS using Windows backup disks that I created a few years back. (The OS has been corrupted when the power has been accidentally deleted from the system and the battery was dead)

    Restoring backup widows put everything on 444 GB C drive.  Nothing I put on the SSD drive d:-20 GB and there is nothing in the tools of HP E: drive - 4 GB

    How can I make use of the SSD drive to help speed up the system?  I see the system starts and runs more slowly now.  I'm ready to blow the current operating system and re-run the Windows backup utility.  But I need to know how to use the SSD during the restoration.

    Any help is appreciated.

    Thank you

    Bob

    Hey @llebrez,

    Welcome to the Forums of HP Support! This is a great place to find solutions and help our community!

    I understand that you have some information about using the SSD in your HP Pavilion dm4 Beats Edition Entertainment Notebook. I'd be happy to help you with that.

    The SSD in your laptop is used for a technology called Intel Smart Response. Intel Smart Response uses the SSD as a type of Cache smart to help load the items faster. The reason why that is not used currently is because the restoration of the system is not designed to use the SSD for intelligent caching and is not able to establish that on its own.

    If you want to configure Intelligent caching on your laptop, you can follow this guide provided by overclock.net: how: implement the Intel Smart Response Technology (SSD caching)

    I hope this helps. If you have more questions that I'm able to answer for you, please do not hesitate to ask.

    Please hold me.

    See you soon.

  • How to use the platform of character even in the same scene several backgrounds without looping the platform of character chronology

    How to use the platform of character even in the same scene several backgrounds without looping chronology of the platform of character? Is it still possible without having to do the scene with another background on another file? To better explain the situation, I have a flash file which has a background and a rig which passes to another context and drilling on another layer and keyframe, but when I go back to the previous background and chronology of this drilling rig repeats, rather than leave, you are doing a new time for this platform. Do I need more than one file?

    In order to reuse assets to animate, you need to duplicate each symbol in the scene who will be the new animation. So, copy and paste the stage on a new layer, right-click on it and select double symbol, then double-click inside the symbol and select each symbol that is going to change, so that the background and the rigging and also select symbol duplicated for those files as well. usually, when I animation I do not use the main platform in the scenes, duplicate as 'Guy1_sc 1', then place it in the scene so that the path I never uses the master file. 'Guy1_sc 2' is a different file. Also if you lipsync and stalled the head separately you will need to reproduce, so, for each scene, is also unique. I hope this makes sense.

  • How to use the same services-config for servers the and remote.

    My flex project works very well using the bottom but when I download my flash on the server I do not work, all the files and related paths are the same execpt remote is a linux server.

    <? XML version = "1.0" encoding = "UTF-8"? >
    <>services-config
    < services >
    < id = 'amfphp-flashremoting-service' service
    Class = "Flex.Messaging.services.RemotingService"

    < / channel-definition >
    < / channels >
    < / services-config >

    I think the problem is the line


    " < endpoint uri = ' http://localhost/domainn.org/AMFPHP/gateway.php "class="flex.messaging.endpoints.AMFEndpoint"/ > "

    but I don't know how to use the same services-config for servers the and remote.

    I'll back up a bit.

    Breakpoint URLS are defined as follows in the services - config.xml:

    https://{server.name}:{server.port}/{context.root}/messagebroker/amfsecure

    The meaning of each of the tokens is clearer when we see them as part of a complete url. If your context root is set to http://localhost , then I have no idea how your application runs in any environment.

    If you leave the server.name and server.port chips in your configuration file, then they will be replaced when executing according to the location from which your application is served. However, the context.root token is replaced at the time of the compilation based on the value that you specify in Flex Builder or when calling mxmlc.

    In order to reuse your file services - config.xml, you must use the same context-root on your development environment and to your deployment environment.

  • With no headphone jack, how to use the iPhone in my car 7

    Okay, so here's the challenge.  I have a power source and a headphone and not Bluetooth.  It works perfectly with iPhones before 7.  But with 7, it isn't possible to use the same configuration I had for years.  I own my car, and I have no interest in buying a new car just to support a new phone.  And since this will be a problem for the years to come if I stay with Apple, I would like to know what are the solutions are available.

    So, how to use the new iPhone 7 while remaining responsible and using my car speakers?  Dongles Bluetooth that I need to reload, it's probably not.

    Thus, looking for ideas that might have people.  I can't be the only one with this concern.

    It's almost a certainty that a third party adapter will appear quickly. The new Macbook has a single port usb - c and people asked the same question, 'how to load and use USB at the same time." There are today dozens of solutions for the Macbook, and then it will be with the iPhone 7. An adapter with a 3.5 mm jack and a port of loading Lightening would be my guess. Kickstarter entrepreneurs are probably already working on it.
