After update triggers using

Hello world

I'm writing a tirgger update of a column in the second table when a column in the first table updated with a value greater than zero (0). I look at many examples of tirggers after update but can't find how to declare keys in the first table to the second for the update. My trigger is similar like below

CREATE OR REPLACE TRIGGER EMP_ADD_TYPE

AFTER UPDATE

OF YADT

ON PREMIERE_TABLE

REFERENCING NEW AS new OLD IN the old

FOR EACH LINE

DECLARE

BEGIN

If: new.yadt! =: old.yadt

then

Update seconde_table set abat1 = 'X' where second_table.empid = first_table.empid;

end if

END EMP_ADD_TYPE;

Column EmpID is key in the two table and similar.

Thanks for your help...

Hello

Try it below:

CREATE OR REPLACE TRIGGER EMP_ADD_TYPE

AFTER UPDATE

OF YADT

ON PREMIERE_TABLE

REFERENCING NEW AS new OLD IN the old

FOR EACH LINE

DECLARE

BEGIN

If : new.yadt > 0

then

Update seconde_table set abat1 = 'X' where empid =:old.empid;

end if;

END EMP_ADD_TYPE;

  • Problem after update 2.0

    I've just updated today. Subsequently, I made a minor change to an existing Muse site, and it will not be rendered in Chrome.  It is agreed so far in IE, Firefox and Safari, but very slow to load.  The two error Windows Chrome as follows:

    "Object has no method"Muse brochure"[object Object]" and "Spry is undefined.

    The site is blurred and an album and slideshow are missing.  Maybe more, but it is difficult to distinguish what is there and what isn't.

    I use export HTML with Amazon Cloudfront.  Is there any solution for this?

    You must re - download ALL the files and folders exported from 2.0 the first time you download after update or use the new built-in FTP download.

    The new built-in FTP download it will automatically and then it will automatically generate and download only the changed files. Try manually assumes that the files have changed and need to be downloaded is very questionable.

  • I can record is more than all of the new bookmarks after update to Firefox 40.0.2. I have over 1000 bookmarks and also use xMarks.

    I can record is more than all of the new bookmarks after update to Firefox 40.0.2.
    I have over 1000 bookmarks and also use xMarks.
    I tried to remove 5 bookmarks and save a new bookmark, but it does not work.
    When I click on the bookmark star, stars in the bookmarks folder jumps, but does not record, it does not offer the possibility of filing in the subfolder right it me and the star is not awarded (there should be one filled with stars when the Web site is updated bookmark)

    Thank you for your help. I tried the maintenance of places without success. I have disabled xMarks, but it made no difference, I couldn't save all new bookmarks. I went on the site help above and deleted the "places.sqlite" file and recreates a new file, but it didn't work. I uninstalled Firefox full using IOBit Uninstaller and reinstalled, but I found this program does not delete the profile folder (used to have a checked during uninstall of Firefox, but it seems to have disappeared in the latest versions). The problem persisted.

    Finally, I took a screenshot of all my addons. Then, I uninstalled Firefox again, then delete the entire folder profiles (located very usefully described in the second link above https://support.mozilla.org/kb/Bookmarks+not+saved#w_fix-the-bookmarks-file )
    I reinstalled Firefox, reinstalled xMarks and connected and transferred all my favorites, I reinstalled all my previous addons and ALTO - it now everything works perfectly!

  • After updating to release 21.0, I'm more able to join a meeting by using Microsoft Lync 2010 online if Firefox is set as my default browser.

    After updating to release 21.0, I'm more able to join a meeting by using Microsoft Lync 2010 online if Firefox is set as my default browser. I am invited to "Join the meeting using your web browser" or "download and install Lync participating." None of these options work. Join using web browser results in a command prompt to install missing plugins, but then no appropriate plugins can be found. Try to install Lync Attendee fails because Lync 2010 is already installed.

    I also tried to install the beta version of Firefox 22.0, but the problem persists.

    Hello ScottRey, please try this: enter about: config in the firefox address bar (confirm the message information where it appears) and search for the preference named plugins.load_appdir_plugins. Double-click it and change its value to true (a restart of the browser may be needed later for the change to take effect). some information on the issue are explained in http://www.ghacks.net/2013/05/15/why-you-may-have-lost-access-to-plugins-or-extensions-in-firefox-21/

  • After update to FF12 - use of the cpu, slower and unresponsible

    Nothing new - he had year ago and I couldn't fix it. Now, the issue is back. Firefox after about 10-20 minutes starts to work slow awfuly. Like, goes to a small number of new tabs makes good unresposnible a few seconds, the browser does not respond to what that it either, typing is 'invislbe' and only appears after a few seconds, then there frozen again for a while, as all scripts on the newly opened site needs good two seconds for himself. At that time, the uses of FF upward at more than 25% of my CPU (AMD Phenom 955 BE - 4 hearts, 3.2 GHz with 8 GB DDR3 RAM). And it also affects the whole system - everything is "stuttering" FF is doing. And it appeared that after the upgrade of FF11 to FF12 - similar thing that's happened in the last year, when I had to completely re - install the whole browser after update. And now, I'm new here, too tired to even think of clear all, completely new installation FF and import all the stuff.

    I tried to reinstall soft, started in Mode safe mode with disabled modules (same thing, after some time, the "suttering" occurs), clear memory cache, re - install Java (which seemed to help a little). Any ideas what the hell is wrong? I don't want to create a new profile and move everything - I want my current profile over to work as it should. I'm really tired of who - I am also using Opera and Chrome (I am a developer web, so I need them), but I like FF the more, but with this problem occurring over and over again after a while, I really think to give up Firefox.

    My problems were related to the addon of all in a sidebar. Which have been set by the last update.

  • By using the system restore before computer restart after updating Windows 10...

    I chose to try the upgrade of Windows 10 on my laptop primary.  Because of the long installation times, I started late in the evening then followed finishing (or almost) the update the next morning.  Until I sat down to 'start' I spoke with a friend who had just completed an installation of two heavy day of problems.    Although I am good enough to solve computer OS and software installation problems, I was very reluctant to go forward.   After serious soul searching I elected continue to use Windows 7, I don't really like.

    That's why I chose to use the system restore before restarting my computer needed complete Windows Update 10.  I chose the previous restore point before the update of windows 10 and ran through the entire procedure and then restarted the computer after the restore point.

    Everything worked fine and I was able to do the foregoing... Except that I can't do updates of security that have been uninstalled.   The Windows Update screen repeat "you must restart your computer...". "with the reboot by holding the active button.

    This window doesn't go away even after reboot, and I can not "check for Updates".

    Does anyone have any suggestions on how to reset this program if I can do all the updates except Windows 10 security.

    Thank you for any assistance.

    By using the system restore before computer restart after updating Windows 10...

    Sorry, System Restore does not cancel the major updates, that's why a lot of automatic updates delete all system restore points. The tool that is appropriate in this case would be a restore Image. If you have not created an image before the upgrade, then you are out of luck.

  • after update of cc, I can't use photoshop cs6 without logging in cc.  Is there a way to get around this?

    after update of cc, I can't use photoshop cs6 without logging in cc.  Is there a way to get around this?

    I do nothing stored on the cloud, all work is local and I do not have to be connected.  It also seems to make Photoshop a LOT slower.

    Hello Christy,

    If it's a standalone Photoshop CS6 (ie you have a serial key) there is no need to connect to the desktop creative cloud application.

    If you have downloaded the 'previous Versions' CS6 creative cloud desktop application so you will need to stay connected on the creative cloud desktop application.
