Typed tables is treated in the same way as a relational table?

I'd like to know if the internal struct of oracle treats a typed table (table that contains object) in the same way of a relational table. For example, if I insert an object (that contains the atribute name as varchar2) into a typed table, and insert a regular register (name as varchar2) into a relational table, theoretically the execution time for both inserts must be the same? Thanks.

> I have written my comments from my experience.
I have used nested table with more 10+ levels with
more than 400+object types for our projects.
As you know bench mark is not done for 1 table or 1
object, it is done with major project usage .
In which case you're not benchmarking a specific feature, but the overall design of the system.
I too am using object tables for specific Oracle applications. And the advantages that this provide significantly outweigh the cons - and a single such application process in excess of a billion rows per month per object table per month.
> If you think Object is faster than relational tables
in oracle then JAVA MUST BE FASTER THAN 'C' Language.
Where did I say that object tables are faster than relational tables? How about trying to read what I said and then trying to understand what I conveyed?
I said that
a) objects tables are marginally slower than relational tables
b) this performance difference cannot be used as the primary deciding factor on whether to use object tables or not
As for your analogy that then "Java must be faster than C" is not relevant. Comparing apples with bananas. C is not C++. Java p-code is not machine code. So your analogy is meaningless and does not prove anything. Fact is that the speed of any programming language depends on numerous factors - and not just the language itself as you're are implying with this flawed analogy.
Besides, trying to compare ADTs in Oracle to Java Classes, is silly. These are different tools intended for different usage.
Bottom line - saying that ADTs and object tables in Oracle is "Bad" based purely on a marginal performance difference is idiotic. The design of the system and requirements of the system dictates the tools that are needed. And one of those tools can be and will be ADTs and object tables in certain cases.

  • Query for retreiving table names that have the same data

    Hi,
    Does anybody know how to retreive all the table names that have the same data in their respective tables but i dont know the table names or its fields. Is there any possible query to perform this action???

  • How to get BufferedImage to treat zero in the same way as MemoryImageSource

    Hi!
    I was wondering if there is a way for BufferedImage to treat the value zero, i.e. 0, the same way as MemoryImageSource. After some testing I have found out that if the integer array that is used by MemoryImageSource contains a zero pixel value, it is treated as no value and the given background color to drawImage is used. When using BufferedImage, with type TYPE_INT_RGB, the zero value is treated as black.
    The problem is that I need to replace my MemoryImageSource instance with a BufferedImage to handle dynamic update better and I do not want to redesign the whole pixel array. Is there a way to get BufferedImage to treat 0 value pixels the same way as MemoryImageSource, i.e. treat them as no value and use the background color.
    Would really appreciate some help!
    Best regards
    Lars

    Have you tried using an ARGB image type instead of RGB? Then you can set the alpha of pixels you want to be transparent to zero.

  • Table is not in the same position form 1 page to next

    Hi,
    Following my earlier posts regarding my website and the lack
    of text. I thought if I created a new index page with text and and
    enter site button this would go some way to sorting out the
    problem. The problem now is that the indes page table is not in the
    same plase as the tables on the other pages. Any assistance on
    getting these lined up would be much appreciated.
    The URL for my site is:
    http://www.martingreshoff.co.uk
    The code for my new index page is as follows:

    What are these (on the linked page)?
    <a href="#" onMouseOut="MM_swapImgRestore()"
    onMouseOver="MM_swapImage('Image8','','Resourses/Images/Gallery
    Free
    Second.jpg',1)"></a><a href="#"
    onMouseOut="MM_swapImgRestore()"
    onMouseOver="MM_swapImage('Image9','','Resourses/Images/Gallery 3
    Fitted
    second.jpg',1)"></a><a href="#"
    onMouseOut="MM_swapImgRestore()"
    onMouseOver="MM_swapImage('Image10','','Resourses/Images/Gallery 4
    Box
    Second.jpg',1)"></a>
    If you had a menu row at the top of the table on this page,
    like you do on
    the other pages, the table would be in the same place. Just
    put an empty
    row up there....

  • What is the right  way to display a table in Java web dynpro using a node.

    Hi experts,
      I am trying to show a node of cardinality 0...n as a table in an adobe form in Java web dynpro. But its not showing it properly. Can anybody please tell me what is the right way to display a table on adobe form using a node of cardinality 0...n or 1...n in Java Webdynpro.  In ABAP webdynpro, we can drag and drop a node of cardianlity 0...n or 1...n to  show as a table and it works fine. Is the same possible in Java webdynpro also. Please help.
    Thanks and Regards.
    Vaibhav Tiwari.

    Please refer to my post.. you will get the answer
    Dynamic Table -  same data repeating in all rows
    Special care should be taken in designing the context for table attribute.
    The attribute type singletone also plays a important role. I have this doubt from the beginning when you have reported this problem for the first time but finally you marked it as solved so i thought there might be some other issues but again when you reported that again i did some analysis.
    Now coming to final solution :
    For designing a table in adobe interactive form you have consider following
    You have to design the view context upto three level, I am explaining you the properties
    PDFDataSource (Parent Level1) - Cardinality 1:1 - Signetone -True - This is assigned to datasource
    TableList (Parent Level2) - Cardinality (1:1) - Signetone -True
    TableWrapper(Parent Level3) - Cardinality (0:n) - Signetone -True
    TableData (Parent Level4) - Cardinality (0:1) - Signetone - false (This is the main point)
    Then under TableData value node, you have to put all your table attributes.
    This Value Node name can be anything but hierarchy should be same as I have mentioned above.
    Please try out these steps and get back to me if you have any doubt.

    That is a quirk of Pagesthat  it applies only one record per page.

  • Want the mouse behave the same way as a tab key

    Hello,
    I am using abap webdynpro. one of my requirements to automatically put the user in insert mode on numeric fields.  That is when the user clicks in a numeric field we want the field to be highlighted.  As soon as the user types something in the field we want the field  to be cleared so that the user overwrites the data.  Basically we want the mouse behave the same way as a tab key.  highlight the field and clear it as soon as you start typing. 
    is this possible?

    As mentioned this is not possible.
    however, I would be wary of trying to overcome a standard functionality "deficiency " like this by implementing an island. If you take this path - all your custom applications will behave differently from the SAP standard ones - which is not really an ideal situation.
    Instead, add your concern to the sticky at the top of this forum - the functionality to "clear" a field (or select all on field on entry which is what is happening with the tab selection) might be added in future releases.
    I think however, that you'll find that the "select all on tab" behaviour is an browser "functionality" rather than anything specifically that SAP has implemented - if you try using a different browser, you may not find the same thing happening (although with the browsers I've checked it does).
    The same thing happens with any HTML forms - just try yourself. e.g.[external site with details on HTML forms and input fields|http://www.w3schools.com/html/html_forms.asp]

  • Can't iPhone have Thai keyboard the same way as the PC keyboard?

    I been using iPhone since 3GS, 4, and now 4S.
    I been using WhatsApp communicating with my friend and family a lot.
    Since I'm from Thailand, I use Thai keyboard in WhatsApp most of the time.
    iPhone Thai keyboard is very difficult to type.
    Can't iPhone have Thai keyboard the same way as the PC keyboard?
    iPad already has it.  Why can't iPhone has it?
    Many Thai people feel the same way as I am.
    Many iPhone user in Thailand jailbreak their iPhone because they want the keyboard the same way as PC keyboard.
    All iPhone user must use the keyboard everyday to communicate.
    Imangine that Thai people have to use the keyboard everyday and having a hard time using it.
    Please consider giving Thai people the keyboard that we can use with ease.

    To turn on Thai keyboardin your iPhone with iOS4.0.2++, follow the steps below.
    1. Go to settings
    2. Select General
    3. Select Keyboard
    4. Select International Keyboards
    5. Select Add Keyboard...
    6. Search for Thai
    This should add Thai keyboard to your iPhone.
    In order to use Thai keyboard during text SMS/MMS,
    Tap and hold on the lower left where there is a "Globe" like icon. You should see a small window with a selection of keyboards available. Without letting go, run you finger (still holding to the globe like icon) to Thai and you should be able to start typing in Thai.

  • I do not see where to enter IP addresses in the Open VPN setup. Also, how can I set it up so that I can choose different servers in the same way as I can currently choose them with my VPN app but for PPTP?

    I think I have it working on my iPhone 5. But, I do not see how I can control the exit point that I would like for the VPN. Are all the exit points shown in the VPN setting now going to work with Open VPN, or do they remain PPTP? If I am reading correctly, they look like they remain PPTP. If I cannot control the exit point for open VPN, which exit point is the default in the profile you provided me?I note that Open VPN Connect does not work with any of the new 64 bit devices like the iPhone 5S, the iPad Air, and the new iPad MIni. Is there any chance that you guys will come up with an update for your app so that open VPN can be made to work on all iOS devices? That would be nice, particularly if the Open VPN Connect app does not give me a choice of exit points.Thanks,
    I do not see where to enter IP addresses in the Open VPN setup. Also, how can I set it up so that I can choose different servers in the same way as I can currently choose them with my VPN app but for PPTP?
    Just a quick note to tell you that Open VPN has updated their app so that it is compatible with 64 bit ARM devices like the iPhone 5S, the iPad Air, and the iPad Mini Retina.That does not resolve the problem of how to easily choose among the various possibilities for the exit server. We need to find an easy way to choose.

    Thank you for trying the new Firefox. I'm sorry that you’re unhappy with the new design.
    I understand your frustration and surprise at the removal of these features but I can't undo these changes. I'm just a support volunteer and I do not work for Mozilla. But you can send any feedback about these changes to http://input.mozilla.org/feedback. Firefox developers collect data submitted through there then present it at the weekly Firefox meeting
    I recommend you try to adjust to 29 and see if you can't make it work for you before you downgrade to a less secure and soon outdated version of Firefox.
    Here are a few suggestions for restoring the old design. I hope you’ll find one that works for you:

    HI Martin,
    i am not realy sure what you want!?!?
    i think you want to display only a part of the values you read from XYZ
    so what you can do:
    write all the values in an array.
    the size of the array is the max. value of the slide bar
    now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
    the other option is to use the history function of the graphes

    I can save a cropped image or an adjusted image. Thanks, Lily A.

    Hi Matt, thanks for your reply.  Have realised that Zoom in Iphoto is just  a viewing tool and not an editing tool.
    Was creating beautiful abstractions by zooming in and wanted to create a new image of the result.   Have since discovered that cropping after zooming takes me a little way to where I want to go but it isn't the same effect.  Will perhaps have to try to create it when actually shooting.  Am doing a photoshop course in February and maybe will learn a bit more then, too.  Am pretty much an amateur just finding my way.
    Thanks again,
    Best, Lily
