• Why we use the cursor

  Hi all

  I would be grateful someone right me if I'm wrong. I ask the question below just for my purpose of learning.

  Question - Why do we use the cursor?

  Response Cursor is used to treat several lines in PL/SQL.

  Or

  Is used to treat a set of records from one or more tables, you can write a cursor on the table using select statement and then you can browse through all these a Recordset, and perform your required operations.

  Question - When we use Procedure and Function when?

  Response

  When you want to run a series of DML statements then do like us and when we want to return a single value, then we use the function.

  Much has been written on this subject.  Start by finding some of them:

  https://www.Google.com/#q=when+use+procedure+function+Oracle

  read some of them and then ask a more specific question

  Procedures are not just for the DML; There are a lot of things in addition to DML you can do in the procedures.  For example, you can send e-mail messages, or can read and write files.

  The second half of your response, 'when we want to return a single value, then we use the function', is the right of bascally.  In particular, when you want to return a value that will be used in a SQL statement, you use a function.

  Functions in the pipeline are a special case.  A lot of what you read or you say about 'functions' means implicitly 'no Pipeline functions.

  You'll have best results if you start a separate thread for each separate issue.  This issue is completely separate from the question on procedures

  You're right that the sliders are a way to process the rowsets, which can contain 1 line or several lines.

  Yes, you can use a slider to manage the rows one at a time.  Do not forget that it will be less effective than the manipulation of all at once, so don't use a cursor to do something that can be done in a single SQL statement.

• When to use the cursor for loop and the cursor (open, fetch, close)

  Hello world
  I have a small doubt about when to use the cursor for loop and when to use the cursor for loop and the cursor (open, fetch, close).
  Well, I'm not the difference between implicit and explicit cursor. So please tell me how I got to know, what to use and when?

  All SQLs are analyzed, stored and executed as cursors. Thus, you will always use a cursor.

  The problem is that languages, such as PL/SQL, provide different interfaces to interact with the SQL cursor. As the ref, the slider interface, the interface DBMS_SQL slider interface and so on.

  Each of these interfaces offers different features. For example, using the interface DBMS_SQL allows binding dynamics and dynamic recovery. The Ref Cursor interface allows your code PL/SQL pass a handle to a reference pointing to the SQL cursor, to an external client. Etc.

  The fundamental reason for the use of an explicit cursor interface is mainly that you own and manage bulk made extraction output provided by PL/SQL cursor.

  With a cursor FOR , the motor loop of PL/SQL optimize the loop by extracting block a 100 lines both. However, you cannot access this collection in bulk directly inside the loop.

  With an explicit cursor interface, you specify the size of the extraction in bulk via the clause LIMIT , and you set the variable of collection to use. This allows you to use the collection directly variable inside the loop.

  However, the need to do - code manually in bulk collection - rarely occur in the daily programs in PL/SQL. A line of treatment is both slow and not well fits. And even if your bulk code collects lines, these lines must still be processed one at a time in your code. It is much more efficient and scalable rather write SQL code, and make the engine SQL the line of treatment for you.

• Satellite A100-549: BSOD after I used the recovery from another PC

  Hello.

  Had a few probs with my laptop and decided to recover it using another pc recovery disc.
  I get the laptop is a Toshiba a100-549. Unfortunately for some reason I can't disks that were originally with her.

  The opertaing system is Windows xp. The disks I got with a Vista.
  It loads OK but goes to a blue screen after 30 seconds and restarts. Is there a reason for this and can I do.

  I think I may need to get your hands on a good drive and load it on again.
  Someone at - it copies of drives for this laptop and able to send me their. I'll gladly pay for them...

  Colin

  Hello

  Don t user recovery drive to another PC, because it won't work.
  You can use a clean Windows OS disk or the Toshiba recovery disc.

  Why? Because the recovery disk contains an image. The image is a package containing a Windows OS, drivers and other software.
  If you want to use the recovery from another PC disk then all the drivers, tools and software distributed for this PC will be loaded on your Toshiba laptop.
  This can cause the BSOD!

  So if you n t have the Toshiba recovery disc then you should use MS Windows CD!
  Toshiba drivers can be downloaded from the Toshiba page!

  It seems the upgrade from Win 7 to win 10 Home edition, in navigation or by using a Microsoft Office program, the windows Explorer.

  When you move the cursor with the touchpad and then listen to select a link, function etc. anywhere on the screen/page.

  The screen will decrease in size to the left or right of the screen or reduce to the taskbar.

  Clues, there is problem Win 10 or touchpad.

  Thank you

  I think I solved the problem because now I think.

  To check the HP site looking for updates to Win 10 and none were found.

  But then I changed my version of Windows to win 8 then rechecked updates and there is an update for the touchpad dated March 2016.

  Downloaded and installed, and everything seems OK so far.

  Thanks again.

• Point display XY graph using the cursor data

  Hello all, I use XY graph to display amplitude v/s time. During the vi execution, data are continuously plooted on chart until the user stops the vi. I want to add a feature, such that, during the execution of the vi, when the user clicks on the chart to the situation with the cursor, it should show corresponding value of time and amplitude of this point. I mean the value of the axis corresponding to the category axis not the cursor position. When you use the position of the cursor, it is ok with the x axis, but it shows the cursor position for y axis (as property said), and I want datavalue said not not the position y axis.

  I hope it's clear with the question. I would like to have a few examples... for y = x graphic below, you can see cursor x = 4.4 and y = 6.8, how to view corresponding datapoint which must be y = 4.4

  When creating (or even after you've created), choose "align on the" plot 0.

  Do not let it be 'slide free.

• How to choose the maximum value in a column of a table by using the cursor and iteration

  Hello everyone
  I have a table loan_detail
  and a column inside loan_amount
  now I want to take the values in this table with the cursor, then using iteration that I want to take a max value of him using this slider
  Here is my table

  LOAN_AMOUNT
  
  100
  200
  300
  400
  500
  5600
  700

  I could make using the concepts of single loop, but when I tried to do by using the slider I wasn't able to do.
  Concerning
  Prost

  You can get the maximum value for a particular column in SQL, PLSQL needn't; Always avoid PLSQL so you can do it in SQL. But always as an example:

  declare
  number of Temp: = 0;
  Start
  for news in some loan_amt of loan_detail
  loop
  If (temp
  end if;
  end loop;
  dbms_output.put_line (temp);
  end;

• Problems to use the cursor to select the format of pdf text precisely

  When you try to select a bit of text that is in a text (as opposed to a text box) on a form object, the cursor highlights several other items of text on the page.

  I'll try to reproduce it below:

  It is just the nature of the documents in pdf format, or is this something that can be avoided.

  I made sure to give each its own name text object, but the problem persists.

  Let's say that I tried to highlight all the end of this sentence.

  Note that the other texts are selected as well.  This would happen in a form when I would try to select only the text: "the end of this sentence."

  Its not impossible to select the text I want in acrobat, but it seems to be very sensitive on the forms. Just to have the cursor slightly outside the central axis of the text, and half of the shape is selected.

  Is it possible to make it more like the text in a text field?

  Thank you!

  Nope!

  It's just the way it is.

• Cycling pictures using the cursor.

  Hi, I am a complete newbie to flash (it took me 10 minutes just to find out where to put actionscript code lol). In any case, I'm doing a flash where you can scroll through the images using a scroll bar. These are images of a face of people of 13 angles from 90 degrees to the left, looking at the Center, right 90 degrees. I want to be able to turn the face using the slider. What I'm trying to do is similar to another thread, I read (but not exactly the same goal) so I took the code from there just to started get me. Currently when I test the movie face moves backward (looping) and the scroll bar does not interact with the images/images. This is the code that I have 1 image 1 layer. I know that this code can be completely wrong for what I wanted to do since I pulled it of someone elses project.

  function f (mc:MovieClip, x 1: number, y1:Number, x 2: Number, y2:Number) {}

  MC.m =(Y1-Y2) /(x1-x2);

  MC.b = Y1 - mc.m * x 1;

  }

  f(mc_slider.mc_handle,mc_slider.mc_rail._x,1,mc_slider.mc_rail._x+mc_slider.mc_rail._width-mc_slider.mc_handle._width,mc_frame000._totalframes);

  {mc_slider.mc_handle.onPress = Function ()}

  this.startDrag (width of false, mc_slider.mc_rail._x, this._y, mc_slider.mc_rail._x + mc_slider.mc_rail. _ - mc_slider.mc_handle._width, this._y);

  clearInterval (current);

  Current = setInterval(dragF,50);

  }

  {mc_slider.mc_handle.onRelease = mc_slider.mc_handle.onReleaseOutside = Function ()}

  this.stopDrag ();

  clearInterval (current);

  }

  function dragF() {}

  frameNum = Math.round(mc_slider.mc_handle.m*mc_slider.mc_handle._x+mc_slider.mc_handle.b)

  trace (mc_frame000 + "" + mc_slider.mc_handle.m + "" + mc_slider.mc_handle.b +"" + frameNum)

  mc_frame000.gotoAndStop (frameNum);

  }

  And this is the code that I put in the symbol for the slider-

  This.PERC = 0;

  {handle.onPress = function ()}

  this.startDrag(true,0,0,rail._width,0);

  {this.onEnterFrame = function ()}

  perc=Math.round(this._x*100/rail._width);

  }

  }

  handle.onRelease = stopDrag;

  handle.onReleaseOutside = stopDrag;

  Any help would be appreciated, thanks!

  Thus, faces is not set on the timeline that contains this code (at the time where the trace() function).

  Click on an empty part of the scene (or behind the scenes) and then click on your movieclip of faces on stage.  in the properties panel, on the left side, type 'faces' without the quotes.

• Counter trigger using the output of another counter

  Hello

  I want to configure my USB-6221 Panel in the next mode

  1 Counter0: Generates impulses in continuous mode.

  2 Counter1: Fires by the impulse of Counter0 (rising edge) and generates a train of 128 pulses with a certain frequency.

  3 DigitalInput: Using the impulses generated by the meter read 128 digital input values

  Cnt0: _____|______________|______________|______________|_________

  Cnt1: ______|||||||||||| _________|||||||||||| _________|||||||||||| __________|||||||||||| ___

  DigIn:___xxxxx___xxxxx___xxxxx___xxxxx___

  The problem is: I can't seem to trigger the Cnt1 using the output of Cnt0.

  If I connect using the Cnt0InternalOutput: I get the error: this connection is not supported by the Board of Directors

  If I connect the trigger for a PFI (e.g. PFI5) I get the error: some resources used Cnt0 (I see no reason why by ok).

  I tried for awhile to do in a different way (I completely mixed my vi) but I did not.

  If anyone has any suggestions please shear them.

  Thank you

  Ignore my previous post.

  A mistake is this sample clock: finished sample doesn't seem to work with shutter release in this configuration.

  In any case, I found a way to get around and reach my final goal (the object) with a bath other counters and configuration of digital input.
