How to properly code for exception management?

• FOR exception management loop

  Given the following code:

  for x in my_cursor loop
      begin
          <<stmt_1>>
          <<stmt_2>>
      exception
          when others then
              <<log_error>>
      end;
  end loop;

  Say there are 5 x in my_cursor. On the element x 3, stmt_1 works fine but stmt_2 throws an exception. I would like to restore ONLY the work done on x 3 (in this case, stmt_1), then continue the loop of the next element, x 4. Can this be achieved with a combination of backup/restore point?

  In this particular case, I would suggest that you follow the third example I posted where you stand on the core of your loop in a procedure such that you change only the values of a and b If your insert succeeds, that is

  CREATE OR REPLACE PROCEDURE proc_name( p_x IN NUMBER, p_a IN OUT NUMBER, p_b IN OUT NUMBER )
  AS
    l_tmp_a NUMBER;
    l_tmp_b NUMBER;
  BEGIN
    SAVEPOINT s1;
    l_tmp_a := p_a + p_x;
    l_tmp_b := 1/(6-l_tmp_a);
    INSERT INTO test_tbl VALUES( l_tmp_a, l_tmp_b );
    p_a := l_tmp_a;
    p_b := l_tmp_b;
  EXCEPTION
    WHEN <>
    THEN
      ROLLBACK TO SAVEPOINT s1;
  END;
  

  You can, of course, have the same local variables of the TMP in your original code. Or you could replicate the calculations, i.e.

  for x in 1..5 loop
  begin
    savepoint s;
    insert into test_tbl values(a+x,1/(6-a));
    a := a+x;
    b := 1/(6-a);
  exception
    when others then
      rollback to savepoint s;
  end;

• BlackBerry - how to properly manage a TAP/CLICK in a custom handler

  I need to set up an event of click/tap for a custom Manager.

  The Manager contains a few items, but I need that all respond to the event Manager, so if the user taps/clicks No matter what item in the Manager, the event handler should be called also. What I've done is to attach a changeListener to a NullField which takes the width and height, but the fieldChanged method is never called

  public class TestManager extends Manager{
      private BitmapField _icon;
      private LabelField _lblTitle;
      private NullField nullField;
      public TestManager(Bitmap pIcon){
          super(Manager.FOCUSABLE);
          _icon = new BitmapField(pIcon);
          _lblTitle = new LabelField("This is the title");
          nullField = new NullField(NullField.FOCUSABLE);
          add(_icon);
          add(_lblTitle);
          add(nullField);
              nullField.setChangeListener(new FieldChangeListener() {
  
          public void fieldChanged(Field field, int context) {
              doSomething();
          }
      });
  
      }
  
      public void doSomething(){
      System.out.println("do something!!");
  }
      public void paint(Graphics graphics)
      {
         graphics.setColor(Color.DELIMITER_COLOR);
         graphics.fillRect(0, 20, Display.getWidth(), 50);
  
         super.paint(graphics);
      }
  
      protected void paintBackground(Graphics arg0) {
         arg0.setColor(Color.LIGHTGRAY);
         arg0.fillRect(0, 0, Display.getWidth(), Display.getHeight());
         super.paint(arg0);
      }
  
      protected void sublayout(int width, int height) {
          setPositionChild(_icon, UIFactory.getBestX(10), UIFactory.getBestX(8));
          setPositionChild(_lblTitle, UIFactory.getBestX(60), _topMarginTitle!=0?UIFactory.getBestX(_topMarginTitle):UIFactory.getBestX(15));
          setPositionChild(nullField, 0, 0);
          layoutChild(_icon, width, UIFactory.getBestX(50));
          layoutChild(_lblTitle, width, UIFactory.getBestX(50));
          layoutChild(nullField, width, height);
          setExtent(width, height);
      }
  
        protected boolean navigationClick(int status, int time){
              invalidate();
              doSomething();
              return super.navigationClick(status, time);
          }
  
  }
  

  How can I do this whole handler to respond to a click/tap?

  I use the API 5.0

  Thanks in advance!

  The problem with the help of the NullField of to do, it's that NullField is not programmed to handle any interaction except update.

  If you need to replace navigationClick, like you did for the Manager.  So that it connects to your plumbing FieldChangeListener (which is the right thing to do in my opinion. you must call fieldChangeNotify, for example):

          protected boolean navigationClick(int status, int time) {
                  this.fieldChangeNotify(2);
                  return true;
          }
  

  Now you will replace it in the NullFeld because it gets the focus.  You must make sure that nothing else in the Manager is focusable.

  But you will need some guidance in the manager who is has the focus, so that the user knows - especially for when the user is using the trackpad.  To do this, make a focusChangeListener for the NullField Manager and have the listener code set a flag if the focus was acquired or not and then invalidate() himself.  In object check the flag and if it is set, paint for focus, if not, paint for any developed.

  Come back if this is not clear.

  Byt the way, the sublayout in your manager looks a bit ropey to me, it's especially this:

  setExtent (width, height);

  You really want to show to what extent being large enough to accommodate all your field and no more.

  There are other things that I'm not sure, but if it works for you, then I guess it's OK.

  Good luck

• How do to make the simplest code for dynamic data?

  Hello world!

  I have a JSON file with more than 200 records.

  I want that each record to be active button with unique actions.

  The code is the following:

  $.getJSON ("content.json",

  {function (Data)}

  for (var i = 0; i < 200; i ++) {}

  var s = sym.getSymbol("base").createChildSymbol ("template", "CONT");

  s.getSymbolElement ();

  s.Element.attr ('id', 'symbol' + i);

  s. $("imageholder") .css ({'background-image': "url ('" + data [i].) "}) (image_+_«_'_»)});

  s. $("imageholder") .data ('myIndex', i);

  s.$("imageHolder"). Data('title',Data[i].) (Name)

  s.. Click$ ("imageholder") ("click", Function {}

  If ($(this) .data ("myIndex") == 0) {}

  WB = 10;

  SYM.$("#symbol0"). Show();

  SYM.$("#Symbol1"). Hide();

  SYM.$("#Symbol2"). Hide();

  SYM.$("#symbol3"). Hide();

  sym.getComposition () .getStage ().getSymbol('placer').$("holder").css ({'background-image': "url (" + $(this).data('Large') + ")"});

  sym.getComposition () .getStage ().getSymbol('placer').$("holdertxt").html ($(this) .data ('the kid'));

  If (WB == 10) {}

  sym.getSymbol("#symbol0").$("rect").animate ({opacity:1}, 700);

  };

  }

  ElseIf ($(this) .data ("myIndex") == 1) {}

  WB = 11;

  SYM.$("#symbol0"). Hide();

  SYM.$("#Symbol1"). Show();

  sym.getComposition () .getStage ().getSymbol('placer').$("holder").css ({'background-image': "url (" + $(this).data('Large') + ")"});

  sym.getComposition () .getStage ().getSymbol('placer').$("holdertxt").html ($(this) .data ('the kid'));

  If (WB == 11) {}

  sym.getSymbol("#symbol1").$("rect").animate ({opacity:1}, 700);

  };

  }

  });

  s. $("imageholder") .mouseout ("mouseout/mouseouthandler()", function (e) {}

  If ($(this) .data ("myindex") == 0 & & WB! = 10) {}

  sym.getSymbol("#symbol0").playReverse ("selectend");

  }

  ElseIf ($(this) .data ("myindex") == 1 & & WB! = 11) {}

  sym.getSymbol("#symbol1").playReverse ("selectend");

  }

  }

  });

  s. $("imageholder") .mouseout ("mouseout/mouseouthandler()", function (e) {}

  If ($(this) .data ("myindex") == 0 & & WB! = 10) {}

  sym.getSymbol("#symbol0").play ("selectstart");

  }

  ElseIf ($(this) .data ("myindex") == 1 & & WB! = 11) {}

  sym.getSymbol("#symbol1").play ("selectstart");

  }

  });

  }

  });

  How is possible to place an each command or something else for not writing for each Index and for each function actions?

  Now I'm writing for each function (passing of the mouse, click, mouseout/mouseouthandler()) the actions that each record in the JSON must do.

  Can someone help me?

  Based on your code above, I made the following assumptions:

  1. You have shown the code for two values of i (0 and 1) and want a similar code for the rest
  2. Two managers mouseout/mouseouthandler() in the code above is a typo, one of them is supposed to be a mouseover (according to the description at the bottom). In the solution, I will propose, I guess that one was supposed to be a manager of mouseover
  3. BM is a global variable and values range from 10, 11, 12... 10 + n - 1. Please check the code once though, I think that there is a logical problem with the closure, you create around WB in mouseout/mouseouthandler() handlers. I can't identify the intention if the proposed solution will be based on your code above.

  Another bug in the code is in the way you join managers:

  s.. Click$ ("imageholder") ("click", Function {}) must be changed to: s.$("imageholder"). on ("click", Function {})

  and still other managers.

  You can use the following to simplify your code:

  $.getJSON("content.json", function (data) {
       for (var i = 0; i < data.length; i++) {
            var s = sym.getSymbol("base").createChildSymbol("template", "conts");
            var e = s.getSymbolElement(); 
            e.attr('id', 'symbol' + i); 
            s.$("imageholder").css({ "background-image": "url('" + data[i].image + "')" });
            s.$("imageholder").data('myIndex', i);
            s.$("imageholder").data('title', data[i].name); 
  
            s.$("imageholder").on("click", function (e) {
                 WB = 10 + i;
                 sym.$("#symbol0").show();
                 sym.$("#symbol1").hide();
                 sym.$("#symbol2").hide();
                 sym.$("#symbol3").hide();
                 sym.getComposition().getStage().getSymbol('placer').$("holder").css({ "background-image": " url(" + $(this).data('Large') + ")" });
                 sym.getComposition().getStage().getSymbol('placer').$("holdertxt").html($(this).data('title'));
                 sym.getSymbol("#symbol0").$("rect").animate({ opacity: 1 }, 700);
            });
  
            s.$("imageholder").on("mouseover", function (e) {
                 //Looks like a logical bug, please double check.. I don't know how you are controlling WB from outside
                  if(WB != 10 + i) {
                      sym.getSymbol("#symbol0").playReverse("selectend");
                  }
           }); 
  
            s.$("imageholder").on("mouseout", function (e) {
                 //Looks like a logical bug, please double check.. I don't know how you are controlling WB from outside
                 if (WB != 10 + i) {
                      sym.getSymbol("#symbol0").play("selectstart");
                 }
            });
       }
  });
  

  Another option would be to set up your event handlers in the symbol definition. The advantage is that all instances would automatically inherit the behavior. You just need to understand how to set the code. For example, in your case, you can attach the following click on Manager in the symbol itself imageholder element:

  var i = sym.$("imageholder").data('myIndex');  //You will be setting the data on the instance while creating the instance. Rest of the code can use this as a param
  WB = 10 + i; //Assuming WB to be available, change the logic accordingly
  sym.$("#symbol0").show();
  sym.$("#symbol1").hide();
  sym.$("#symbol2").hide();
  sym.$("#symbol3").hide();
  sym.getComposition().getStage().getSymbol('placer').$("holder").css({ "background-image": " url(" + $(this).data('Large') + ")" });
  sym.getComposition().getStage().getSymbol('placer').$("holdertxt").html($(this).data('title'));
  sym.getSymbol("#symbol0").$("rect").animate({ opacity: 1 }, 700);
  

  The code does not work as it is, but I hope it helps you move forward and you are able to achieve what you wanted. Let us know if you encounter other problems.

• common code in oracle exception Manager

  Hi all
  
  Here is the situation where I'm stuck...
  The current code handles all errors as shown below:
  WHILE OTHERS
  THEN
  IF cur_hdr % ISOPEN
  THEN
  CLOSE Cur_hdr;
  END IF;
  
  IF cur_det % ISOPEN
  THEN
  CLOSE Cur_det;
  END IF;
  
  ECODE: = SQLCODE;
  emesg: = v_trace_str | SQLERRM;
  SM_CONTROL_PKG.
  handle_db_error (v_package_name |) '.' || v_procedure_name,
  emesg,
  v_trace_str,
  (TRUE);
  V_RETVALUE: = 1;
  ROLLBACK;
  end;
  
  
  Now, I was asked to introduce an error more, it is a user-defined error.
  so I defined
  no_detail_for_header_ex EXCEPTION;
  
  In my code, I say,
  Open the cursor in the header
  Open detail slider - there no line
  
  So I say
  v_trace_str: =' no details for header-ERROR '
  Rossanna no_detail_for_header_ex;
  
  But in part, exception management
  I say,
  
  When no_detial_for_header_ex then
  IF cur_hdr % ISOPEN
  THEN
  CLOSE Cur_hdr;
  END IF;
  
  IF cur_det % ISOPEN
  THEN
  CLOSE Cur_det;
  END IF;
  
  ECODE: = SQLCODE;
  emesg: = v_trace_str | SQLERRM;
  SM_CONTROL_PKG.
  handle_db_error (v_package_name |) '.' || v_procedure_name,
  emesg,
  v_trace_str,
  (TRUE);
  V_RETVALUE: = 1;
  ROLLBACK;
  
  
  If you can see, the code is the same.
  close cursors and call the handle_db_error.
  
  I don't want to code the same thing again.
  Here, errors are different, but handled the same way. only the trace_str varies.
  
  I want to write something like
  When no_detial_for_header_ex or other PEOPLE can
  same code.
  
  is this possible with others.
  or any other suggestions.
  
  Thnaks in advance.

  Sure. Just declare the parameters in your cursor, then move them during the call of loop.

  cursor my_cursor (my variable)
  is
  select .... from .... where column = my variable;
  
  for cursor_rec in my_cursor (my value)
  loop
     ...
  end loop;
  

  A google for cursor for loop syntax should clear up any questions. Consider reading the Oracle pl/SQL and documentation.
