better option than a loop of validation?

I am running 11.2.0

I'm looking at the setting of a sql statement, and the issue was raised as to the max inserts by transactions in 11g, and if it is greater than 1000.
I have not yet found a solid answer, but I thought that 10g was higher than 1000.

In any case...
My first thought was to implement a loop of validation on every 1000 lines, because that's how things were handled in the past.
But I found an article that talks of redo logs and performance and how it is a horrible practice to do the validation loop.

What I did find is what is the best methodology by doing this?

My scenario could meet as much as 20 000 inserts at the same time.

Thank you.

There is no limit. So yes it is greater than 1,000

Insert directly in select

My scenario could meet as much as 20 000 inserts at the same time.

Here is an example on a database of development of the small insertion of 1 million lines in less than 10 seconds

SQL> create table t (n number, a varchar2(50), b varchar2(100), c varchar2(200));

Table created.

SQL> set timing on
SQL> insert into t
  2  select level, rpad('a', 50, 'a'), rpad('b', 100, 'b'), rpad('c', 200, 'c')
  3  from dual connect by level <= 1000000;

1000000 rows created.

  • Insert (ignore duplicates) have a better performance than the merger?

    Insert (ignore duplicates) have a better performance than the merger (insert if not duplicated)?

    Well, it isn't that much of a performance issue if you need to insert in respect of business rules (your unique index), is it?
    In any case, the MERGE statement is quite effective. You also have the option to INSERT NOT EXISTS, or as I said above the ERRLOG option...
    But as already said earlier, hard to say which option will be faster without knowing anything of your system (application, OS version,...).

  • What makes "new queue path" to write to the File.vi worksheet? I need a better explanation than what is given.

    You are looking for assistance.

    What makes "new queue path" to write to the File.vi worksheet?  I need a better explanation than what is given.

    Thank you.

    You can call this function without wiring to a path of the input file.  If this is the case, the function prompts the user for input file using a pop up dialog box.  If a file is selected and you press OK, it is the path of the file that is out of the function as the new path of the file.  If you press the button cancel instead of OK, the "not a path" constant is the new output file pathname.  If the function is called with a wired file path entry dialog box appears, the same path of file entry becomes the new output file path.

    Glad that RIM is not a car manufacturer...

  • Is it a restoration better program than on my Toshiba w/Vista, XP restoration program has given more options to restore date?

    My last laptop has XP, this Toshiba Satellite L355 S7905 restore that does not offer the calendar pop-up bit to choose several dates and times. When I tried to restore everything on to recover the change in mouse pad, only restore points were last year and the same or previous - year date, but the time AFTER I would accidentally made the mouse pad change. I save to an external drive HP but do not know how to restore that. The restore/backup program always wants me to back up to CD. I did it at first, until he got to need too much CD to copy everything. Y at - it a program that gives points to restore most recent that this program Vista OS, and if I can replace the one I have with a better program?

    Hello

    Did you make a backup image or backup of the data on external hard drive?

    Backup and restore of Windows Vista application is integrated applications and cannot be replaced by any other program. However, you can use your favorite search engine to search for any other Microsoft backup and restore application.

    In order to restore the backup to a disk external I suggest you to follow the steps and check if it helps:

  • Can I trust this site to clean my registry? __ou, is there a better option?

    I found this link on other sites more than three times.

    She claims to clean my registry and make my computer more fast (in fact, I got a laptop).

    Can I trust her?

    Here is the link:

    If you really want to do a scan of the registry (which is not really necessary), http://download.cnet.com/ccleaner/?tag=mncol CCleaner is the BEST.

    Mr. teen geek did not recommend me this link as mandatory or similar incentives.
    Yet the link is neither Microsoft or a partner, I doubt the recommendation.
    I won't make any registry cleaner way, but given that others can visit this page and read the answer, in my view, an explanation of your part is in order.
    Thanks for your quick response.

    CCleaner is a good program.

    BUT its primary pupose is not like a registry cleaner.
    And I still say let this part of the program alone, do other more knowledgeable posters here too.

    http://www.SnapFiles.com/reviews/CCleaner/CCleaner.html

    CCleaner is a tool to clean your system from temporary and unnecessary files that accumulate over time. This includes also rather a cleaning of the traces of Internet and PC use as browser cache, files recently used, websites visited and more. You can select the items you want to clean and also specify cookies that should not be deleted.

    "In addition, the program comes with a scanner to register for references not valid (advanced users) and options to start cleaning automatically or the command line. (Slim version, no toolbar")

    Its main objective, explained above, is good enough to use.

    See you soon.

  • Loop of validation software license

    So this is about the 5th time I've completely uninstalled, deleted all files from Adobe, then run Adobe Creative cloud cleaning with absolutely no progress.  I download the software creative cloud let him do is setting up and downloading thing and when he finally I get a creative cloud window that has just a rotation inside circle.  Start (Windows 7 Ultimate) Task Manager and stop the process Adobe CEF Helper.exe * 32.  Suddenly, I get a login screen that I can enter my info in.  Type in and everything looks good and I'm able to download for Photoshop beginners.  Wait until it has finished and install and then I launch.  Now it turns on and says I have version of evaluation but 90 days remaining, click the connection option and he thinks about it for a minute and then opens a new box that says software license validation.  Cannot get past this step at all, just guard verification then closing then popping up.  I tried the suggested fixes that say to remove the opm.db file of /Application Support/Adobe/OOBE, but everything that is me to sign again.  All advice to get this software to the top and the work would be greatly appreciated!  On a side note, Acrobat DC works very well and never request a secondary connection, or validation, it even automatically log on my account with a list of all my files.

  • Playback options - play once, looping or just continue to play

    When I hit the space bar hiding it in about 10 seconds of video and then especially just a loop, but sometimes he will continue to play the clip in place. Is there a way to define what is happening? In the Preview tab, I loop options and to play once but do not just continue to play the full scenario.

  • Creating a DVD with camera HDD as source - better items than first pro + yet?

    Hello

    I recently received a request to transfer the video to a basic SD HDD camera that creates files encoded to mpeg - DVD and I leaned in some options to do so.

    There is one thing I need to clarify a bit of everything, and I hope someone here can help.

    In Premiere Elements the dvd creation and video editing is in the same program, and it seems to me that after mounting and press on create disc, there is a process of encoding taken to create vob files.

    In the Premiere Pro / again workflow, however, it seems that Premiere Pro first encodes mpeg compatible dvd, and then after importation do files again it is possible that again also transcodes the mpeg files to make them go up a dvd.

    Which if true, would make the worst material quality target in this workflow compared to first elements.

    If so far, I have concluded that given the source that I use for video, it seems I want to get the best output quality by using items first that

    Prempro/still.

    My observations are correct in this case?

    Now, I know I could probably set the encoder settings so that the files do not match a dvd disc, but I prefer the approach where I just say "4.7 GB dvd" to avoid transcoding in Encore and figures the encoder to what compression to use.

    I don't know where to stop, but I see that it should have been earlier. Still, if others have similar questions, they have a few comments to fall back on.

    What you describe, I think that PrE will work fine. However, still can do the same thing, if used correctly. Pre has just done the same behind the scenes and will actually run faster. It's like having a really good Adobe Dynamic Link built in. Account only, which might swing my vote to pre, with the description of your project. Now, done correctly, the resulting video DVD will have only a small difference - the burn speed is automatically configured in pre. This will NOT affect the quality, but could play a role in the gameplay on various set-top players.

    Regardless of your choice of authoring software, use better blank media you can. It boils down to Verbatim or Taiyo Yuden. There are other Virgin Media, Falcon, that gets good reviews from a respected here, contributor Jim Simon. I have yet to try it, but just on the REB.

    Good luck

    just wonderning which access method is more intensive CPU, supposed to leave we got 2 the same rank sources and make joing via merge join Cartesian and then case is nested loop.
    I know that nl can be CPU due to the tight loop access, but what abour MJC?
    I can see bufferd sort but not sure is that cpu friendly?
    Concerning

    The simplest answer I think is "it depends on the situation." Two of them could be disaster in different situations. Nested loops are suitable for a type of join and Cartesian for another.
