• What happens when you enable paging in the range?

  Hi all
  
  Recently, I started tuning VO potentially able to return a lot of data. Explore the documentation I've read on the beach of paging:
  section http://docs.Oracle.com/CD/E16162_01/Web.1112/e16182/bcadvvo.htm#BCGHDDAD "42.1.5 scroll efficiently with large result sets using range paging"
  
  Section "42.1.5.3 What happens when you enable paging in the range" tells us that the thrust is enveloping the original query to produce a Top - N query like this

  The actual query produced to wrap a base query of:
  
  SELECT EMPNO, ENAME, SAL FROM EMP
  
  looks like this:
  
  SELECT * FROM (
    SELECT /*+ FIRST_ROWS */ IQ.*, ROWNUM AS Z_R_N FROM (
      SELECT EMPNO, ENAME, SAL FROM EMP
    ) IQ  WHERE ROWNUM < :0)
  WHERE Z_R_N > :1

  Oracle, told us http://docs.oracle.com/cd/B19306_01/server.102/b14200/statements_10002.htm#i2171079
  >
  Use the ORDER byclause order the rows returned by the statement. Without an order_by_clause, there is no guarantee that the same query that is run more than once will retrieve the lines in the same order.
  >
  
  So, it seems that we can ignore certain lines of original request?
  The example below illustrates this situation.

  SQL> 
  SQL> create table tst(
    2    id    number
    3   ,name  varchar2(100)
    4  )
    5  /
   
  Table created
  SQL> insert into tst(id,name) values(1,'Name1');
   
  1 row inserted
  SQL> insert into tst(id,name) values(2,'Name2');
   
  1 row inserted
  SQL> insert into tst(id,name) values(3,'Name3');
   
  1 row inserted
  SQL> insert into tst(id,name) values(4,'Name4');
   
  1 row inserted
  SQL> SELECT 'Page1', ID, NAME FROM (
    2    SELECT /*+ FIRST_ROWS */ IQ.*, ROWNUM AS Z_R_N FROM (
    3      SELECT ID, NAME FROM tst order by dbms_random.random
    4    ) IQ  WHERE ROWNUM < 3)
    5  WHERE Z_R_N > 0
    6  union all
    7  SELECT 'Page2', ID, NAME FROM (
    8    SELECT /*+ FIRST_ROWS */ IQ.*, ROWNUM AS Z_R_N FROM (
    9      SELECT ID, NAME FROM tst order by dbms_random.random
   10    ) IQ  WHERE ROWNUM < 5)
   11  WHERE Z_R_N > 2
   12  ;
   
  'PAGE1'                                  ID NAME
  -------------------------------- ---------- --------------------------------------------------------------------------------
  Page1                                     1 Name1
  Page1                                     2 Name2
  Page2                                     3 Name3
  Page2                                     2 Name2
  SQL> SELECT 'Page1', ID, NAME FROM (
    2    SELECT /*+ FIRST_ROWS */ IQ.*, ROWNUM AS Z_R_N FROM (
    3      SELECT ID, NAME FROM tst order by dbms_random.random
    4    ) IQ  WHERE ROWNUM < 3)
    5  WHERE Z_R_N > 0
    6  union all
    7  SELECT 'Page2', ID, NAME FROM (
    8    SELECT /*+ FIRST_ROWS */ IQ.*, ROWNUM AS Z_R_N FROM (
    9      SELECT ID, NAME FROM tst order by dbms_random.random
   10    ) IQ  WHERE ROWNUM < 5)
   11  WHERE Z_R_N > 2
   12  ;
   
  'PAGE1'                                  ID NAME
  -------------------------------- ---------- --------------------------------------------------------------------------------
  Page1                                     4 Name4
  Page1                                     2 Name2
  Page2                                     3 Name3
  Page2                                     2 Name2
  SQL> 

  In the first query, we lost name4 in second name1.
  
  Who can shed some light on this?
  Everything is so sad I think, and I should wait for unpredictable data? Or the internal mechanisms are not as described in the documentation and everything works well?
  
  Thank you very much.

  So what is your question? Without a deterministic order by, the top - N query used by the pagination of range feature will not do what you want. It can skip lines. It can reproduce lines on several pages.

  The documentation is correct; things are working properly. The other thing that should be obvious is that if the records are inserted in the game of records and committed between your look a page 1 and page 2, the specific records that appear on page 1 page vs 2 could change.

• Lately when I use the mouse the words text scrolling and copy on top of itself a million times. This happens when I am on line reading something to say on the MSN homepage.

  Lately when I use the mouse the words text scrolling and copy on top of itself a million times. This happens when I am on line reading something to say on the MSN homepage. Sometimes I can click off on the side and separates the text and I can read it but when I use the scroll of the mouse or even the scroll bar on the sideit happens again and again.

  Hi Jaynebasye,

  1. This only happens when you are on the MSN Web site?

  2. did you of recent changes on the system?

  Method 1:

  You can try to change the scroll settings and check.

  For more information, see the following article

  Change the settings of the mouse

  Method 2:

  Step 1:

  You can also check if the problem occurs in safe mode with network.

  Startup options (including safe mode)

  Start your computer in safe mode

  Step 2:

  If you do not experience the problem in safe mode with network, then perform a clean boot.

  A clean boot to check if startup item or services to third-party application is causing this issue.

  You can read the following article to put the computer in a clean boot:

  How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

  Note: Make sure that you put the computer to a Normal startup once you are finished.

  Hope this information is useful.

• What happens when you insert/modify/delete a row in a table - concepts

  I am trying to understand the below concepts regarding the internal concepts (for example, undo and redo)

  (1) what is happening in the database when you insert a row in a table?

  (2) what is happening in the database when you update a row in a table?

  (3) what is happening in the database when you remove one line in the table?

  I have read the oracle documentation and mistook the redo and undo behavior. It would be great if someone explains the concept in a simple way.  I'm a novice programmer to understand database concepts. Any help would be much appreciated.

  INSERTIONS and deletions are handled the same way.  The cancellation of an INSERT is a DELETE.   The cancellation of a REMOVAL is an INSERT.

  Therefore, the generation 'Cancel' for INSERTION is less than that of a DELETION (because the cancellation of a DELETION is to reinsert the line - the value of each column in the row must be captured in the undo).

  If restore you an INSERT, then Oracle executes effectively a DELETE tablename WHERE rowid =... rowid_that_was_inserted.  A cancellation for an INSERTION is 'rapid '.

  If restore you a DELETION, then Oracle executes effectively an INSERT tablename values (col1, col2, coln).  The cancellation of a DELETION takes more time because Oracle would have to re-enter the values.

  Remember that Oracle also captures the redo to undo it (and do it again for the price drop if you do a restore).

• What exactly happens when you change the name of the computer, and it asks you to restart?

  What exactly happens when you change the name of the computer, and it asks you to restart - relating to the registration and identification of network?  Specifically when a computer isn't yet in one area but is still in a working group.  Y at - it show any PC by informing other computers it's name has changed?

  Computers into working groups are actively seeking each other, so if you rename a computer, it will not be shown anything. The restart is to erase the name of origin since the system cache, he will think that it's always the old name until the reboot takes place. Work computers is simply 'shake hands' with each other whenever they need to communicate.

  Computers that are part of a domain are created a 'computer' account that is assigned a random password that changes every 30 days by default automatically. These computer accounts work almost identical to an Active Directory user account, which means that they are not proactive they simply cached credentials with their permissions to provide if / when requested by heritage in the environment.
  Users and computers Active Directory accounts are stored in the NTDS. SAID the database, the backbone of an AD environment. When a computer name changes in one area, it takes the PC restarted simply for the PC. The change of name in Active Directory will replicate throughout the environment based on the settings of replication of this environment.
  I'm too simplify all this, but the general concept is there.

• What happens when you reinstal XP OS with the cd that takes me to service pack 2 and I'm at service pack 3

  I bought TurboTax and downloaded, but can I have downloaded previously because I was unable to install due to the previous installation.  After that 2 hours of phone support with TurboTax including screenshare, they stated that the problem lies in the registry. It was damaged and I had to reinstall my OS.

  What happens when you reinstal XP OS with the cd that takes me to service pack 2 and I'm at SP3?

  I finally found my OS reinstall CD, but it's waaaay above my comfort level... what I do now.

  Frankly, if TurboTax is causing this much trouble, I would use another company as the income tax act.

  Of course, you can reinstall Windows. It's a shame, if that's the only way to solve this problem. :-(
  For later use, it is sometimes necessary to download the installation file, physically disconnect from the Internet, set up a clean boot (using msconfig startup diagnosis), reboot and THEN install the large program (and then undo the clean boot, reboot and re-connect to the Internet).

• How can I get data from each associated XMLnode in movieclips separated when you click a line in the combobox

  How can I get data from each associated XMLnode in movieclips separated when you click a line in the combobox?

  A sample of XML is like this:

  <>planter

  < Lauvtre >

  < Botanisk_navn > Acer campestre < / Botanisk_navn >

  < Norsk_navn > Naverlonn < / Norsk_navn >

  Gronn < Farge > < / fan >

  H4 < Herdighet > < / Herdighet >

  < Hoyde > 10-15 m < / Hoyde >

  < / Lauvtre >

  I have a combobox where it shows the botanical name and the Norwegian name. But the rest of the info in movieclips seem separate.

  Someone has an idea how to do this? Can I use the trace function maybe? Here is my AS3 code so far:

  var loader: URLLoader = new URLLoader();

  loader.addEventListener (Event.COMPLETE, onLoaded);

  list.addEventListener (Event.CHANGE, itemChange);

  function itemChange(e:Event):void

  {

  your. Text = list.selectedItem.data;

  TB. Text = list.selectedItem.label;

  }

  var xml;

  function onLoaded(e:Event):void

  {

  XML = new XML (e.target.data);

  var it: XMLList = xml. Planter.Lauvtre;

  for (var i: uint = 0; i < il.length (); i ++)

  {

  list.addItem ({data: it.}) Farge.Text ([i]) + "\n"+ it.» Herdighet.Text ([i]) + "\n" + it. Hoyde.text ([i]),

  label: it. Botanisk_navn. Text() [i] + "\n"+ it.» Norsk_navn. Text() [i]});

  }

  }

  Loader.Load (new URLRequest ("lauvtre.xml"));

  Thank you!

  Rheus.

  I don't know what you're trying to do.  but, if you want to fill one combobox with the botanical names and when one is chosen, the other use of logins:

  var loader: URLLoader = new URLLoader();

  loader.addEventListener (Event.COMPLETE, onLoaded);

  list.addEventListener (Event.CHANGE, itemChange);

  function itemChange(e:Event):void {}

  var selectedObj:Object = a [list.selectedIndex]

  trace (selectedObj ['fan'], selectedObj ['Botanisk'], etc);

  }

  var xml;

  var a: Array = [];

  function onLoaded(e:Event):void {}

  XML = new XML (e.target.data);

  var it: XMLList = xml. Lauvtre;

  for (var i: uint = 0; i

  list.addItem({label:il[i].child('Botanisk_navn').toString()});)

  a [i] = {'Fan': it [i].child('Farge').toString (), 'Herdighet': it [i].child('Herdighet').toString (), "Hoyde": he [i].child('Hoyde').toString (), 'Botanisk':il[i].child('Botanisk_navn').toString(),'Norsk_navn':il[i].child('Norsk_navn').toString()};}

  }

  }

  Loader.Load (new URLRequest ("test.xml"));
