• The possibility of declaring the variable on request?

  Hello
  
  With the help of Oracle 9i. I'm new to the PL/SQL (coming from c#), I would like to know if it is possible to declare a variable around the where it is used. For example, in the execution of the procedure block, suppose I want to do:
  
  .. existing code...
  
  vTest whole;
  vTest: = 123;
  
  .. existing code (continued)...
  
  In doing so, the procedure could not compile. The only way I know to date is to declare the whole vTest. in the declaration block. Can you please let me know how to declare the variable in the body of the procedure?
  
  Thanks in advance.

  It is technically possible, but I wouldn't recommend it (I personally do not like this approach a LOT).

• Declare the Variable step in a package

  Hello

  Is it obligatory to declare a variable in a package, even when we are refreshing or set the value of this variable in the package? What are the problems that occur in the case where a variable is not declared in the package?

  Please note that I understand that the variable must be romance in the package in case it is not be refreshed or set or incremented but is used by any step in the package.

  Thank you and best regards,

  PV

  Hi PV.

  You must declare a variable, unless it is explicitly used in the package to arm, refreshing or evaluate its value (as you mentioned).

  You must declare also specifically when:

  • You want its value to be passed during execution (runtime scenarios)
  • You want to use in the name of the resource to a data store in a scenario

• declare the variable binding

  I do homework here and ran into the wrong hope that someone here can help
  
  1. I thought that I understand the conscept of variable binding (which I think it is the same concept as the pointer in C/C++ programming), is that correct?

  This is the way of declaring bind variables in SQL * more.

  In a PL/SQL block, you do not use bind variables like SQL * more. You just use normal variables. The PL/SQL engine is smart and sends SQL statements to the SQL engine containing all PL/SQL variables converted to bind variables. If it works transparent in PL/SQL and you don't have to do something more.

• Declare the variable in the loop or abroad?

  What is the smartest, if the statement is a loop much like 100000. Is there a difference?
  
  * for(int i = 0; i < 100000; i++) {*}
  Dim myStr = getSomething();
  *}*
  
  or
  
  Dim myStr = "";
  * for(int i = 0; i < 100000; i++) {*}
  myStr = getSomething();
  *}*

  No, there is no performance difference (that's what you thought, weren't you).

  The basic rule by declaring variables is "the smallest scope possible. So in this case inside the loop for.

  It is not necessary to declare variables in the package specification. In fact, if you declare the variables var1 and var2 in package specifications, they will be different variables var1 and var2 in test_proc.

  Variables used only within a procedure must be declared in the procedure, like var1 and var2 in your example.
  The variables declared in the package body will be global to all, but not visible outside the package.
  Variables declared in the package specification will be visiible outside the package.

  only parameters is fine  ???
  
  i,e var1 and var2 
  

  Sorry, I don't understand the last part of the question.

  Moreover, few matter where you declare a VARCHAR2 variable (not an argument), you must specify the maximum length.
  For example

   var1  varchar2(100);

• How to access the variable in the child video clip

  I have a flash file that uses php to manipulate a database and returns a variable (data_xml) to document data in XML from the database. In this case, as well as others within the parent company. Now, I have a child movieclip that shows analyzed data, but I'm unable to access the variable from the child movieclip. The code associated with this is:

  var myXML:XML = new XML();
  var myXML = XML (event.currentTarget.root.data_xml);

  and I get the following two errors that point to the second line as the problem:

  1151: there is a conflict with definition myXML in the internal namespace.

  WARNING: 3596: duplicate variable definition.

  I unchecked automatically "declare instances of the scene" because I have seen the one proposed for the 1151: error, but I still have not the same two errors.

  Can anyone help? Thank you!

  You've declared the variable twice. Variable can be declared only once in any scope. So, your code should be:

  var myXML:XML = new XML();
  myXML = XML (event.currentTarget.root.data_xml); Note there is no before var

• where and how to declare global variables

  I am creating a Flash multiple-choice quiz. I created a clip named mc_Quiz. This clip contains a layer of action and an object layer. THW action layer contains 1 keyframe with code (code of a button that moves to the next section).
  
  The object layer contains 11 contains keyframes 10 the KeyFrames
  a single movie clip question, (mc_Q1 through mc_Q10) and a btnNext to move to the next section. The video clips in question (e.g., mc_Q1) contains a "btnCheck" button and the code to check the answer.
  
  The 11th framework contains a film click that contains an input text box 'userName', a 'score' of the user's dynamic text box and a submit"" button. Not yet submit the information anywhere, I do it so that when I click on the "present" enter key 'Please enter your name' if it is empty. " And if it is not empty, it will be 'Thank you.'
  
  What I have to do is to have the 'btnCheck' to add 10 points for each correct answer to a variable. Then place this total in the 'rating' dynamictext box when the user moves the frame 10 to 11. I don't know where declaring the variable and how to add the variable every time the correct answer is given.
  
  How this is done?
  
  Here's something that does not work.
  
  First image of "mc_Quiz":
  
  Stop()
  var advanceNext:Number = currentFrame;
  static var; userScore:Number;
  btnNext.addEventListener (MouseEvent.CLICK, nextQuestion);
  
  function nextQuestion(evt:MouseEvent):void {}
  gotoAndStop(advanceNext ++);
  }
  
  
  
  As part of "mc_Q1".
  
  Stop()
  messageBox.text = ""; Clears the response area
  var correctAnswer:String = "Holy"; Good response for comparison games
  var userAnswer:String; with the value of the radio button group.
  var rbg:Object = rbA.group; Get the name of a group from the first button ragio.
  
  
  btnCheck1.addEventListener (MouseEvent.CLICK, checkAnswer1);
  
  function checkAnswer1(evt:MouseEvent):void {}
  userAnswer = String (rbg.selectedData);
  If (userAnswer == correctAnswer) {}
  messageBox.text = "Yes", + userAnswer + ' is CORRECT! ";
  userScore = score.value + 10;
  rbA.enabled = false;
  rbB.enabled = false;
  rbC.enabled = false;
  rbD.enabled = false;
  }
  else {}
  messageBox.text = "your answer is INCORRECT.";
  rbA.enabled = false;
  rbB.enabled = false;
  rbC.enabled = false;
  rbD.enabled = false;
  }
  }
  
  In fact, I have no idea where to declare the variable or how to add 10 points when I select the right answer. It seems to me that I have to some how change this variable within the function of the button.
  

  AS3 does not directly support global variables, like its predecessors, but there are ways around it. Without going through the overall road, to communicate from a child object to a parent the normal approach in AS3 object would (literally)...

  MovieClip (this.parent) .totalScore += 10;

  Alternatively, you can create a world class and use that. If you save the following in a file named "global.as" in your class path (or file that your project is the folder), you can use the variable in a global sense, while importing the class where it is needed:

  package
  {
  public const global: Object = new Object();
  }

  Use it in the Flash file...

  global import;

  global.totalScore = 0;

• Cannot declare a variable CNiTimer in a header file * view.h

  It cannot declare a variable CNiTimer in a header file * view.h?

  I run a MDI VC2005 project with extention of studio OR measure. I have check the project example of "TemperatureSystemSDI.2005." It works very well.

  But when I use the following statements in * view.h, compilation, errors are reported:

  Code:

  Class CVAView: public CFormView
  {...

  public:
  CNiTimer * m_pTimer;

  ...

  }

  Error:

  ERROR C2143, C4430.

  At the first beginning, I assume that the error might occure when the failure of the header file include. But when I include the following headers, there are still compilation errors.

  Code:

  #include "NiGraph.h".
  #include "NiSlide.h".
  #include "NiTimer.h".

  This time, compilation errors are:

  Error C2440, C2548, C2143, C4430, even more than the cases do not include those headers.

  I don't know what the problem is. I just declare a variable of CNiTimer! Could you please help me.

  Add #include 'NiUtilityComponent.h' or use the Studio remove measure class library Wizard (in the Measurement Studio in Visual Studio menu) to add a reference to the library of utility classes. Files * Component.h aggregate all the necessary header and library includes a library for C++ Studio action.

  If this does not work, please attach your project and we will take a look.

  The collections have some counts; scalars don't.

  l_numbers is a collection, so you can see the number of items contained in it like this:

  DECLARE

  List_of_numbers_t TYPE TABLE IS NUMBER;

  l_numbers list_of_numbers_t: =.

  list_of_numbers_t (1,2,3);

  BEGIN

  DBMS_OUTPUT. Put_line (l_numbers. (COUNT);

  END;

  /

  l_numbers (1) , however, is just a scalar NUMBER, you can't use COUNT on it

  In other words, l_numbers (1) is the number 1, so we can not say

  DBMS_OUTPUT. Put_line (l_numbers. (COUNT);

  for exactly the same reason that you can't say

  DBMS_OUTPUT. Put_line (1. (COUNT);
