How can I get record count with a query?

In Client/Server pplication,the client send a query to server.
How can server get record count by oracle call interface?
Is it need execute "select count(*) from ...."?

Yes.
Either that or increment a counter for each record fetched and
loop round until you hit the last record.
The first method would be more efficient on large datasets.

  • How can I get Record Count in JDK1.3 version

    Hi,
    I am using a JSP page which communicates with the database and fetches a query using a record set.
    How can I display 10 records per page using JDK1.3.
    Lets say the query fetches 15 records.I want the first 10 records to be displayed and a "Next" link at the bottom which when clicked should show the remaining 5 records.
    Could anyone help me regarding the above issue.

  • I purchased an ablum thru itunes on my phone and it says i purchased the songs on itunes but when i go on my music it says i have to repurchase all the songs how can i get the songs with out havin to pay again

    Whether you can redownload music depends upon what country that you in. If you are using your computer's iTunes then does music show in the Purchased link under Quicklinks on the right-hand side of the iTunes store home page (on your phone you might be able to redownload media via the Purchased tab in the iTunes store app) ? If music shows there, but not that album, then check to see if it's hidden : http://support.apple.com/kb/HT4919
    If you aren't in a country when you can redownload music and it's still on your phone then you should be able to copy it over from the phone via File > Devices > Transfer Purchases.

  • How can I get the variable with the value from Thread Run method?

    We want to access a variable from the run method of a Thread externally in a class or in a method. Even though I make the variable as public /public static, I could get the value till the end of the run method only. After that scope of the variable gets lost resulting to null value in the called method/class..
    How can I get the variable with the value?
    This is sample code:
    public class SampleSynchronisation
         public static void main(String df[])
    sampleThread sathr= new sampleThread();
    sathr.start();
    System.out.println("This is the value from the run method "+sathr.x);
    // I should get Inside the run method::: But I get only Inside
    class sampleThread extends Thread
         public String x="Inside";
         public void run()
              x+="the run method";
    NB: if i write the variable in to a file I am able to read it from external method. This I dont want to do

    We want to access a variable from the run method of a
    Thread externally in a class or in a method. I presume you mean a member variable of the thread class and not a local variable inside the run() method.
    Even

    could get the value till the end of the run method
    only. After that scope of the variable gets lost
    resulting to null value in the called method/class..
    I find it easier to implement the Runnable interface rather than extending a thread. This allows your class to extend another class (ie if you extend thread you can't extend something else, but if you implement Runnable you have the ability to inherit from something). Here's how I would write it:
    public class SampleSynchronisation
      public static void main(String[] args)
        SampleSynchronisation app = new SampleSynchronisation();
      public SampleSynchronisation()
        MyRunnable runner = new MyRunnable();
        new Thread(runner).start();
        // yield this thread so other thread gets a chance to start
        Thread.yield();
        System.out.println("runner's X = " + runner.getX());
      class MyRunnable implements Runnable
        String X = null;
        // this method called from the controlling thread
        public synchronized String getX()
          return X;
        public void run()
          System.out.println("Inside MyRunnable");
          X = "MyRunnable's data";
      } // end class MyRunnable
    } // end class SampleSynchronisation>
    public class SampleSynchronisation
    public static void main(String df[])
    sampleThread sathr= new sampleThread();
    sathr.start();
    System.out.println("This is the value from the run
    method "+sathr.x);
    // I should get Inside the run method::: But I get
    only Inside
    class sampleThread extends Thread
    public String x="Inside";
    public void run()
    x+="the run method";

    read it from external method. This I dont want to do

    Your main thread continues to run after the sathr thread is completed, consequently the output is done before the sathr thread has modified the string. You need to make the main thread pause, this will allow sathr time to run to the point where it will modify the string and then you can print it out. Another way would be to lock the object using a synchronized block to stop the main thread accessing the string until the sathr has finished with it.

  • How can I get a count of objects in the near cache? (Extend client)

    Hi,
    I'm trying to figure out how to get the count of objects in my near cache (from c++ client). Knowing the size of the near cache is a key factor when optimizing configurations for performance.
    However if I call size() on the cache handle I get the count of objects in the cache (ie the cluster). How can I get a count of objects in the near cache?
    Thanks
    Rich Carless

    H Rich,
    It may not be ideal, but I think you may be able to infer the size by using the HeapAnalyzer (http://download.oracle.com/docs/cd/E15357_01/coh.360/e15728/classcoherence_1_1lang_1_1_heap_analyzer.html) facility, specifically the "class" based HeapAnalyzer. Its Snapshot representation http://download.oracle.com/docs/cd/E15357_01/coh.360/e15728/classcoherence_1_1lang_1_1_class_based_heap_analyzer_1_1_snapshot.html provides a mapping between class name and ClassStats (http://download.oracle.com/docs/cd/E15357_01/coh.360/e15728/classcoherence_1_1lang_1_1_class_based_heap_analyzer_1_1_class_stats.html) which provides information on how many instances of a given class type are in memory. Note the reported counts are process wide but if your key or value type are distinct you may be able to infer your answer. I realize this is rather complex, my only other suggestion would be to just make some guesses on size and see how they effect performance.

    How can I get wireless printing with my ipad?

    Best way is to use an AirPrint compatible printer:

    If your printer is not AirPrint compatible, you might want to take a look at Printopia.

  • I downloaded garage band on my iPad ages ago but now it just says waiting and when I click on it it just says "retry" and does nothing. I've spent literally ages making songs (I've got like 20 ). How can I get it back with all my songs still there?

    I downloaded garage band on my iPad ages ago but now it just says waiting and when I click on it it just says "retry" and does nothing. I've spent literally ages making songs (I've got like 20 ). How can I get it back with all my songs still there?

    Thanks for that. Much more constructive than the last comment. It's only the restriction code I can't recall, not the access passcode. So I can currently access the device, just not age restricted content. Does that's make a difference? I also wondered if anyone knew how many attempts you get to try to get it right. Now tried 21 times and so far nothing bad has happened but I am concerned I'll eventually be completely locked out of the device. That doesn't seem in the spirit of things though. Surely it's foreseeable that a child could repeatedly try to guess the code so I can't see that it would be right to lock the device down completely in that circumstance, particularly if the access code is being typed in correctly every time.
    Thanks

    How can I get my ipad2 with os5 to Kodak wireless printer esp9.

    Airprint won't work with the Kodak printers because Kodak does not support Airprint.  You'll need to check in the App store to see if Kodak makes a printing app for the iPad.  Otherwise, there are a number of third party printing apps.  People have used Printopia, Print n Share, and Print Central with good results.

  • How can i get records of all text messages

    How do you get records of all your texts? Everyone tells me to go to text usage for my number but it does not show up. Any ideas? I need them like now

        Hey there Amanda_x,
    I've heard your cry for help and I am here to assist. Are you looking just for the numbers that you've texted and received texts from? Or are you looking for the actual text message conversation?
    If you are just looking for the numbers that you've texted and received texts from you can retreive that information through My Verizon. Once you are signed in as the account owner you would click on "view my usage" under Manage My Account. From there you can click on Breakdown of Recent Activity and from there you can view the messaging log for your line.
    If you are looking for previous text messages that may have been deleted. That cannot be retreived through My Verizon.
    Verizon Wireless is only able to provide an average of the last 3-5 days of content, but never more than ten days from the date and time the message is delivered.  Only messages that are received may be available. We also must receive a message with your consent and have it notarized and submitted by an attorney or law enforcement official.  You can have those documents faxed to (847) 706-7276.
    Let me know if you have any additional questions.
