Triggers on key substitution and modification date

What is the best practice to create a trigger on the surrogate keys and modification date?

You create each trigger individual on all the tables again a sequence on surrogate keys and a update trigger date change = sysdate?
Is there a better way to do it for a large number of tables?

Is it better to use before the update or after the update on the triggers in this case?

Depending on what you mean by "new sequence", Yes. Each trigger can only be triggered by actions on a single table.

Is there a better way to do it for a large number of tables?

You need a trigger for each table. If they are very similar, you could wirte a script to generate the triggers, but it's pretty easy to copy and change the names of table and sequence.

Is it better to use before the update or after the update on the triggers in this case?

BEFORE is better.
You probably want the triggers to fire before INSERTION, too, not only the UPDATE.

  • OS 6.5.1 setting of false creation/modification dates

    Just updated to 6.5.1 this morning and suddenly, all files in all directories have been updated with incorrect or false creation and modification dates. Using this one/mult shared defining where we rsync files between local system and the ReadyNAS, we have huge problems that all the files are in conflict. It also seems the files are updated with a user/group of root/root when each file should be owned by our own users.

    Help?

    It seems that the culprit was the Amazon Cloud Drive sync. I think that the reason 6.5.1 exposed the question was it introduced the 'support for two-way synchronization with accounts Amazon Cloud Drive' email release notes I got from Netgear.

    So, if you use the synchronization of Amazon Cloud Drive, I suggest not upgrading to 6.5.1 until you have disabled it. All then maybe after you upgrade, don't turn it back on? I'm not sure. I don't need to use it, so I'll leave it off.

  • I want out emails in folders of ordinary files, but when I drag-and-drop, the "modification date" gets changed. How I can still see the date?

    To archive my e-mail files until I decided to switch to Thunderbird, I create regular folders in windows and drag and drop emails to outlook express in the appropriate folders. The "update" column displays the original date of the email... which is what I want to do with Thunderbird. In my view, that he treats it as a new file created today... that is not good for my archiving system of these professional work files that I need to find often in approximate date.

    I understand the forum that it is by default in Thunderbird. There is an add-on that can do what I'm doing?

    Thank you in advance,
    Netwon

    I think the reason what OE is the original date because each message is stored in a single file, while TB stores all messages in a folder in a file, an mbox file. Thus, when you save a message as a single eml file, its 'modification date' corresponds to the eml file date was written in the mbox file.

    You can find the ImportExportTools add-on useful because it allows you to add the date of the e-mail eml file name when enamel is exported ("Save selected messages" of the message right-click menu).

  • How to display the version number of the application and the date of the last

    At the Express request User Guide under the heading "Application définition Attribute" description for the Version is as follows:

    Version includes the version number of the application on a page. You can also automatically link the version at the time of last modification by using the following format masks:

    YYYY. MR. DD

    MM DD. AAAA

    DD. MM. YYYY

    I have attempted to use various forms of alternative channels to display this information on a page without success, here are some of the things I've tried:
    and VERSION.
    and version.
    & APP_Version.

    And how would you present and the version number for the date of last modification date?

    Thanks for any help
    Ben

    The substitution of the #APP_VERSION model # seems to only be supported in Page header and footer definitions, not the body. (There are a number of restrictions where work substitutions, which are not well documented).

  • Date of creation and the Date of importation

    When you import photos or video in the Photos to a folder, the application uses the date of importation of integration rather than the original creation date.  The result is that imports are all presented together under "Today."  Many photos and video taken on different dates, so I would only they listed according to date of creation rather than be grouped under the date of importation.  I went 'View' and checked "date of creation".  Photos don't work with "SORT" because it is always grey.  Any help would be greatly appreciated!

    If you look in the window of Photos photos and videos are sorted by date with the oldest items at the top.  This sort order cannot be change.

    In the pictures window, the elements are sorted by the date imported into the library with the oldest at the top.  The sort order cannot be changed here either.

    So, you can use a smart album to include all your photos in the library and then sort them one of these ways:

    The smart album could be created to this criterion:

    that would include all the photos in the library.  Now you can sort them as you like.  Just make sure that the date is early enough to catch all the photos in the library.

    Moments in Photos are new events, i.e. groups of photos sorted by date of catch.

    When the iPhoto library has been migrated first to the pictures there is a folder created in the box titled iPhoto events and all migrated iPhoto events (which are now Moments) are represented by an album in this folder. Use the Command + Option + S key combination to open the sidebar if it is not already open.

    NOTE: it has been reported by several users that if the albums of the event are moved in the iPhoto Library folder in the sidebar, they disappear.  It is not widespread, but several users have reported this problem.  Therefore, if you want to if ensure that you keep these event albums do not transfer out of the iPhoto events folder.

    Is there a way to simulate events in pictures.

    When new photos are imported in the library of Photos, go to the smart album last import , select all the photos and use the file menu option ➙ New Album or use the key combination command + N.  Call it what you want.  It appears just above the folder to iPhoto events where you can drag it into the events in iPhoto folder

    When you click on the folder to iPhoto events, you will get a window simulated of iPhoto events.

    Albums and smart albums can be sorted by title, by Date, with the oldest first and by Date with the most recent first.

  • File modification date/time problem

    Hello

    I'm trying to use file of a file modification date/time to fix a system of synchronization between a blackberry and a PC. However, the date/time of the file is not updated as I expected.

    The following occurs:

    -Using a program, a file is modifidied to make more than 100 bytes.

    -> When checking for windows Explorer (using the mass storage mode to access the file) the change date is updated

    -Using the same program, the file is changed to be the shorter of 50 bytes.

    -> When checking for windows Explorer, the change date is NOT updated

    -Using the same program, the file is modified to be more than 20 bytes.

    -> When checking for windows Explorer, the change date is NOT updated

    -Using the same program, the file is modified to be more than 100 bytes. It is now longer that he has never been.

    -> When checking for windows Explorer, the change date is updated

    The code that updates the file is basically something like this:

    FileConnection connection = (FileConnection) Connector.open (fileName, Connector.READ_WRITE);        {if (!) {(Connection.Exists ())}
    Connection.Create ();
    }
    OutputStream out = connection.openOutputStream ();
    Output PrintStream is new PrintStream (out);.
    output.println ("a lot of text ');

    Various printlns... followed

    output. Close();
    out. Close();
    Connection.Close;

    I use a v4.5.0.55 8310 platform, 2.7.0.68.

    BlackBerry JDE 4.5.0.7

    Any ideas what's wrong?

    Kind regards

    Anders

    Yes, delete the file is kind of a workaround. Last updated date/time will be correct. Created date/time will be of course lost, however, since the time created is generally much less important that her last updated date/time is better.

    I ended up doing the following whenever I change a file of Java code:

    FileConnection connection = (FileConnection) Connector.open (fileName, Connector.READ_WRITE);

    {if (Connection.Exists ())}

    Connection.Delete ();
    }
    Connection.Create ();

    Thank you

  • Modification date instead of the date of Capture in grid mode

    I noticed that in Grid mode (expanded cell information) Lightroom see the change date instead of the date of Capture. How can I fix this?

    Sigh, metadata of image are such a mess, with different programs and operating systems using similar labels for different areas. I suspect what is happening with your images is that some of them didn't have not a metadata field "capture date".  If you download one of the suspicious images on Dropbox and post the link here, I can verify this.  (This is probably the most effective way to solve your problem, rather than a long exchange of posts.)  Also, note that the Date change is not as known as the Date of Capture.

    Gory details:

    The EXIF: DateTime of metadata fields (Exiftool called EXIF:ModifyDate) and XMP:ModifyDate are shown in LR in the metadata > Panel EXIF as "Date Time".  It is a metadata field defined as LR image manipulation programs whenever they change the image or its metadata.   This metadata field is not the same as the last modification date/time indicated by Mac Finder or Windows File Explorer - who is a field maintained for all files automatically by the operating system.

    The time, that the image was captured by a digital camera stores, EXIF:DateTimeOriginal and XMP:DateCreated. These fields are displayed in the form of 'Capture time' in the LR metadata > by default, and as a 'DateTime Original' Panel in the metadata > EXIF.

    When an image is missing EXIF:DateTimeOriginal / XMP:DateCreated, then for its 'Date of Capture' inside, LR 5.6 uses EXIF:DateTime / XMP:ModifyDate (if present), otherwise it uses the date of last modification of the file system.  (Versions prior to 5.6 had a different behavior, buggy).

    AZEL,

    Can you give us more details about your current environment?  What is the size and the data store space used? Do you have any storage of additional network attached to the host (for backup purposes)?

    My assumptions of your post do you have 1 stand-alone host with ESXi 4.1 aready installed and you also have a local data store on the same host, but you want to re - install ESXi 4.1 while keeping the contents fo the data store.  Is this correct?

  • How to use the find method to search for character format substitutions and FMP?

    I strongly suspect that I should be able to use the find method to search for paragraph substitutions and format as these options are available in the Find dialog box. However, because of the excruciating Extendscript documentation from Adobe, I not was able to find the key pieces of information that I need. I found these constants:

    • Constants.FV_FindPgfFormatOverride
    • Constants.FV_FindCharacterFormatOverride

    But he has literally no information about them. It is not yet a definition, so I'm actually just a guess. However, I think that I need to somehow use these constant within the parameters of the Find method. Any ideas on how to do it?

    You're right, there are still some bugs to work out of the documentation, although it has already improved since I started w / Extendscript last summer.

    Find two constants must be defined as the ival for a PropVal FindObject, for example:

    var myDoc is app. ActiveDoc;

    var docStart = myDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;

    tloc var = new TextLoc(docStart,0);

    var findParams = AllocatePropVals (1);

    findParams [0].propIdent.num = Constants.FS_FindObject;

    findParams [0].propVal.valType = Constants.FT_Integer;

    findParams [0].propVal.ival = Constants.FV_FindCharacterFormatOverride;

    myDoc.Find (tloc, findParams);

    Depending on what you're trying to accomplish, you can also take a look at the property FormatOverride of the Doc, bmp and item objects.
