  11.1 and especially you have virtual column

  SQL> create table t
    2  (
    3     a number
    4   , b number
    5   , c generated always as (a+b) virtual
    6  );
  
  Table created.
  
  SQL> insert into t (a, b) values (1, 2);
  
  1 row created.
  
  SQL> select * from t;
  
           A          B          C
  ---------- ---------- ----------
           1          2          3
  

  Before that, a front insert - trigger

  SQL> create table t
    2  (
    3     a number
    4   , b number
    5   , c number
    6  );
  
  Table created.
  
  SQL> create or replace trigger t_default before insert on t for each row
    2  begin
    3    :new.c := :new.a+:new.b;
    4  end;
    5  /

• Sequence by select Help please:

  First of all, I'm rather at this new and need help please.

  I created the following sequence:

  CREATE SEQUENCES SQ_CASE_NUMB

  MINVALUE 1

  INCREMENT BY 1

  START WITH 1

  And from this sequence select it below:

  SELECT TO_CHAR (SQ_CASE_NUMB. NEXTVAL)

  | | To_char (SYSDATE, "fm/MM/yy")

  Case_NUMB

  OF THE DOUBLE

  Result:

  Case_NUMB

  08/01/14

  08/02/14

  08/03/14

  Can I combine the sequence 'create' and 'select '? Or should I create a function?

  What is the best option please?

  It depends on what you're trying to reach.  What you use the sequence for?  Primary key?  Experiment?  fun?

  Best option can be answered only if you provide the object...

  BTW - the select query above works, but it does not mean that you should use...  The best thing to do (if you use it as a primary key) is to create a trigger like this:

  create or replace

  TRIGGER "insert name here".

  BEFORE INSERT ON table_name

  FOR EACH LINE

  BEGIN

  SELECT sequence_name. NEXTVAL INTO: DOUBLE NEW.pkcolumn_name;

  END;

• Help, please! to stop the animation of a symbol of the stadium or anover

  I'm not a specialist of jquery, but I had to deal with it. And have some expirience... But I can't do a basic thing along the busy, I guess. So, help me please!))

  I need to stop certain symbols of the child of the chronology of the symbol of the parent (or stage). The chronology of the scene, I have trigger. Currently, all child clips must stop as a...

  I'm trying to insert into the shutter button, copy the following code:

  (child clips names: 'stan', 'bizan', 'bak')

  var stantostop = sym.$("stan");
  stantostop. Stop();

  var bizantostop = sym.$("bizan");

  stantostop. Stop();

  var baktostop = sym.$("bak");

  stantostop. Stop();

  and I'm sure, I'm doing something wrong (!), cause, nothing changes.

  If you can't help, please advice me some source with many examples of typical operations and commands like this! So thank you for reading!

  Hi, Strashevsky-

  You don't need to refer to the object jQuery if all you want to do is stop the timeline.  You can simply do:

  sym.getSymbol("stan").stop ();

  OR

  var stantostop = sym.getSymbol ("stan");

  stantostop. Stop();

  Hope this help get you pointed in the right direction!

• Should not hide or get rid of front loader bar. Help, please

  [b] OK, why not work?

  Trying to do a

  Navigation bar button, of preloader for abour my page with an element of the picture.

  Not on the charger page pre bar works, it doesn't disappear. [/ b]

  [pre] s [color = blue] iteLoader.loadMovie("AboutMe5.swf",4);

  Frame_movie._alpha = 100;

  loadingBar._alpha = 100;

  loadingBar._xscale = 1;

  loadingBar.onEnterFrame = function()

  {

  kBytesLoaded = this._parent.siteLoader.getBytesLoaded () / 1024;

  kBytesTotal = this._parent.siteLoader.getBytesTotal () / 1024;

  percentage = Math.round (kBytesLoaded/kBytesTotal * 100);

  This ._xscale = percent;

  If ('percentage' == 99) {}

  loadingBar._alpha = 0;

  Frame_movie._alpha = 0;

  delete this.onEnterFrame;

  }

  [/ Color]

  } [/pre]

  [b] the navigation bar has the following script [/ b]

  [pre] [color = blue] Button_AboutMe.onRelease = function() {}

  unloadMovie (4);

  loadMovie("AboutMe_Loader.swf",4);

  } [/ Color] [/pre]

  [b] the loaded movie is just like the script [/ b]

  [color = blue] stop (); [/ Color]

  [b] now, I added this script in the final AboutMe5.swf file to try to hide the bar but does not work, also tried using different layers and the unloadMovie (4); script. It did not work.

  [/ b]

  [pre] [color = blue] unloadMovie (4);

  loadingBar._alpha = 25;

  Frame_movie._alpha = 25;

  SiteLoader._alpha = 10

  loadingBar._alpha = 1;

  This ._alpha = 1;

  Frame_movie._alpha = 1; [/ Color] [/pre]

  [b] now Frame_move is a mov (and I tried the button) and the laoding bar is a mov file. I can do these melted by adusting the alpah, but this only works on the film. I can't trigger it with the line.

  [/ b]

  [color = blue] [pre] if ('percentage' == 99) {[/pre] [/ Color]}

  Ive tried with and without the single and double quotes. and plan.

  tried to replace the percentage with

  This ._xscale

  loading bar

  Nothing works.

  It seems to be the case of script that is the problem do not trigger the ADF or gettig the front loader quite red.

  Help, please

  THANK YOU VERY VERY MUCH

  Finally got it work.

  What on earth we were doing wrong all this time?

  Could you explain to us who know so what Im doing next time rather than cut and paste your script please. Think others benefit from it.

  the script work is

  Stop();

  siteLoader.loadMovie("Aboutme5.swf",4);

  Frame_movie._alpha = 100;

  loadingBar._alpha = 100;

  loadingBar._xscale = 1;

  loadingBar.onEnterFrame = function() {}

  kBytesLoaded = this._parent.siteLoader.getBytesLoaded () / 1024;

  kBytesTotal = this._parent.siteLoader.getBytesTotal () / 1024;

  If (kBytesLoaded > 1) {}

  percentage = Math.round(kBytesLoaded/kBytesTotal*100);

  This ._xscale = percent;

  If (percentage > = 99) {}

  Frame_movie.swapDepths (this._parent.getNextHighestDepth ());

  Frame_movie.removeMovieClip ();

  This._parent.nextFrame ();

  loadingBar.swapDepths (this._parent.getNextHighestDepth ());

• lost or stolen iPhone. It is w / 'Find my iPhone', later received email that it has been found. No call and impossible to recover, now phone is in offline mode. I am leasing through the iPhone upgrade program. Help, please.

  6 sec more lost/stolen iPhone. Turned on the 'lost' Mode and displays the number to call if found on-screen. It is w / "Find my iPhone", went up, no response from any home in the area. Later received an email that it was found, still no call to the number on the screen. Several unsuccessful attempts to get it back, now the phone is in offline mode and says that the history of the site is not available. I left a note on all the doors in the place indicated on the "find my iPhone" describing my phone lost and left a number to call. I am leasing through the iPhone upgrade program. Help, please.

  There is no way to locate now, unless the one who found it exerts a force on you contact on this number you posted

  The good news is, since you have find my iPhone, they will not be able to reuse the phone even if they are trying to restore. Unless they know your password, or you have a valid proof of purchase AGFI won't be deleted.

  So if the person who found the phone knows about it, he or she would rather go back because it would be of no use to them.
