Can ROWID change after UPDATE?

Normally I go no deeper into Oracle than a few basic SQL statements but now I have a problem which I feel must have a simple solution.
I want to be able determine which rows have been updated (or inserted) since my last query. I thought ROWID would do this and by retaining the highest value returned in the previous query (prevROWID) I could used WHERE ROWID>prevROWID but I'm not certain that it ROWID is altered on changes that have occured on INSERT.
Is there a simple solution?
I'm using OLE DB provider to access Oracle which may limit my options.

If I could I would. Unfortunately access to the database is restricted and placing a trigger on all the tables I need to interrogate is a definite no no. This was my original recommendation but it was blown out. Thanks for you prompt reply.

My solution would be:
- Add a DATE-field to the row
- Create a TRIGGER on the table that sets this field to the SYSDATE after every update and insert.
Now you can use this field in your query.<HR></BLOCKQUOTE>

    Is that really a problem?  the second item has has the same PR number. but if you look at the technical structure of the purchase requisition table, then this table does not have a header table and no item table, it is just one table --> EBAN
    if you create a second item, then you have the same PR number but different item number
    otherwise
    you have a different PR number but same item number.
    It is really just one field which is different.
    And 06608 message prevents the change of the item which is already used in a PO.

  • UDF in documents lines that can be Change after adding the doc.

    Dear all
    How can i create a UDF in documents lines that can be change after adding the doc? He need to mark some of the lines to already audit or not audit and the date of the action.
    Kind Regards
    Margarida

    It also depends on what documents you are wanting to add these comments to. On documents such as the A/R Invoice/ Delivery, and A/P Invoice/ Goods Receipt PO you cannot change the UDFs on the line item after the document is added (regardless of whether the document is closed). Sales Orders/ Quotes and Purchase Orders line item UDFs can be changed as long as the line hasn't been closed (or partially received/delivered/invoiced).
    Hopefully that makes sense. I could give more of an explanation if I knew what documents you were wanting to add these line item comments to.

  • Language change after update to Lightroom 3.2! Help asked!

    I use Lightroom from the first version and love to work with it. I always work with the English version of it - for several reasons - even when my Windows XP version is in Dutch.
    By upgrading to Lightroom 3.2 I selected the English language. After the update my version of Lightroom 3.2 however was in Dutch. I tried to change that to English following the help file, but that does not work
    This unwanted change gives me a lot of trouble now as I normally import my pictures with a filename in the date-number format. But the date format in the Dutch version is day-month-year, as I however want to use - and used for over 50.000 pictures!!! - the year-month-day format. I had no trouble with it in Lightroom 3.0. My trouble began after updating to Lightroom 3.2.
    Can anyone help me here, as I cannot import pictures I made in the right format now!!!

  • Can't open after update to v 30.0

    I run Windows 7 and can't open Firefox after updating to v 30.0. I have uninstalled and reinstalled several times with no success. I do, however, show: firefox.exe*32 in the processes section of the task manager. No browser opens and the only way to "kill" it for the uninstalls I have done was to "End Process"; right clicking on the icon in the task bark and clicking the X didn't do a thing.
    Anyone else having this issue?

    It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.

  • Screen brightness not changing after update to windows 10

    Hello, After updating to windows 10, I am no longer able to adjust the screen brightness at all.  It is stuck on the brightest setting at all times; which is inconvenient when I am on battery power and need it dimmed. The f2 and f3 buttons are not working to adjust the brightness, and I am unable to change it in power/power plan settings. I attempted to search for a possible missing driver that I had maybe lost upon updating, but there are yet no drivers for my product on the HP website for this purpose. Any help on this matter is extremely appreciated, as it is rather frustrating that I can't change my screen brightness. Thanks.

    How about using the snipping tool to create an image of what you do see and posting it here.  The snipping tool is what I used to create the image that I posted.  What version of Windows 10 is installed?  I upgraded to Windows 10 Pro on the Omen 15 and have the Enterprise version on one of my desktop systems. I have not yet used the HOme or Education versions, so I do not yet know which features they lack. 

  • Hda and hdb changes after updating

    Hello,
    i've reinstalled my "main computer" a few weeks ago after using it for a year or so with OpenBSD. The System is an old IBM Server which i got used a year ago.
    I've installed archlinux on an SCSI disk which hangs on an onboard-LSI-Controller.
    There is also a bit SATA-Disk which hangs on an PCI-addon-SATA-Controller with an SIL chipset.
    Yesterday i've updatet my System with pacman -Syu, and shut it down yesterday evening. This morning my system won't boot, fsck said "Bad Superblock" or so on sda3 which contains my / filesystem. After a few tries i found out that sda which was my scsi system disk and sdb which was my "big" sata drive switched the letters, so after changing the letters in the fstab, everything works fine now, but i'm a bit confused, as i had never such an issue after updating before.
    Is this perhaps a bug that i should post anywhere? Or have i missed a threat or a news anywhere that announced this behavior?
    Thanks a lot!

    The advice these days is to use uuids which are unique to each volume to avoid these types of problems. the wiki on fstab tells you how. No idea why you experienced this though.

  • Can't publish changes after updating to '08

    I just updated to iLife '08 and was able to publish, though none of the new material came through. Does anyone have suggestions?

    If you are publishing to .Mac, iWeb '06 published to Finder/Go/iDisk/My iDisk/Web/Sites/iWeb and iWeb '08 publishes to Finder/Go/iDisk/My iDisk/Web/Sites.
    Go to Finder/Go/iDisk/My iDisk/Web/Sites and see if your new folder is there. Double click the index.html file to launch your site from .Mac to make sure all is well.
    The URL to get to your updated site will now have the format ....

  • IPod Touch name change after updating to 3.1.1

    After upgrading from 3.0 to 3.0.1 itunes changed the name oftouch the touch. Why, and is there a way I can change it back?

    I experienced the same bug. What is double irritating is that after restoring the name of the iPod, backup in iTunes was starting from scratch, invoking an entire fresh and very long backup of the iPod.
    The 3.1.1 update process was for me the most bug-ridden update yet (and I'm updated from 3.x).

  • Language Changed after update

    I've seen some really competent people in this forum and I decided to submit my problem.
    I've just updated my phone software with the nokia utility software but now the language is changed. I can only choose between English, French and German on both menu and writing.
    The problem is that I'm Italian, the previous software version was italian and of course I've bought my Nokia 6680 LEGALLY here in Italy (in a "nokia point" by the way).
    I can easily manage an english language phone, of course, but some of my friends will have some hard time translating my english, T9-provided short messages.
    Phone details:
    Model: 6680
    Type: RM-36
    Code: 0520999
    FCC ID: PDNRM-36
    Any suggestion?

    If you lost the language, it was still an unauthorized/illegal import, as the update updates the phone with those languages that were put on the phone when the phone was manufactured.
    In other words, the "nokia point" got that phone from somewhere else than ordering it from Nokia directly (otherwise they would have gotten devices with Italian that retained Italian after using NSU).
    You could go back there and ask them to fix the phone, or give you a new one with Italian.
