• 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.

• The function does not properly when you use the shortcut to insert

  Hello everyone. I am using first Pro CC V9.2 on a PC.  I am as well as a Lynda tutorial and told me quite clearly that using the comma key insert a subclip in my sequence.  However, using the shortcut brings in the full clip, not the sub.  I just bring my subclip using a drag and drop, which is really slow me down.  Anyone know what this could be?

• 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.

• 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;

• 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.

• HP laptop, 2000 - 2a20CA: Page of the screen shrinks by using the cursor key

  Laptop HP 2000-2a20CA

  No. B5R61UA

  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.

  HP 2000-2a20CA, running Windows 10 laptop

  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.

• using the button to select distinct values

  I would like to have a button where a user can choose one of four options: 6, 12, 18, 24.  I updated the properties of force and I changed the labels so that it looks only four options are available but it always allows me to choose between 6 to 24 in 1 increments.  I used an indicator to see what data are produced by the control and it shows also from 6 to 24 with increments of 1.  Am just using the wrong control?

  You can use text labels. Right click on the Select button. Right click again and create the visible text display. You can then right-click on the display of text labels and select "edit items". Add as many items as you want and to assign a digital specific to each label, uncheck the box for sequential values.

• JavaScript to set radio button choices using the drop-down list box value.

  I use Adobe Acrobat Pro DC version 2015.016.20039 on a MacBook Pro OS X El Capitan version 10.11.6.

  I have a set of named CitBox radio box choices. I'm defining what choice is selected from out of a drop-down list named AppCitizenship box.  Both of them have six choices with values of 1, 2, etc. (I thought having the same values would make easier the translation from one to the other). Thanks in advance.

  If you used the same values, then it is pretty easy. Just use this code as the validation script custom field drop-down list:

  this.getField("CitBox").value = event.value;

• Using the cursor to another (nested cursors) cursor objects...?

  Now, I'm pretty sure that's not possible, but as a last thought of the station, it would not hurt to ask.
  
  I have a number of fairly complex cursors in PL/SQL (all beautifully packaged upwards), which are used in a number of other different queries for reporting. Because the same cursor is reused several times in different contexts, I want set the cursor once, then use it as a subquery in the other queries. This will also help as if I place the SQL directly in other queries, then it will be necessary propagate the changes to the base query in all other queries which use - and that it will be maintained by a large team that goes forward, it would be wide open to things being missed... (not that I don't trust my colleagues or anything like that...!)
  
  So, in brief and simple terms, if I;
  
  CURSOR curDateList (pi_start_date AS, pi_end_date IN DATE)
  IS
  SELECT pi_start_date + rownum - 1 when
  FROM (select '1' sys.dual connects by level < = (pi_end_date - pi_start_date + 1));
  
  that returns a list of the dates of pi_start_date to pi_end_date, and I want to integrate in another slider like;
  
  CURSOR curEmpWork (pi_start_date AS, pi_end_date IN DATE)
  IS
  SELECT e.employee_id, dl.when, e.work_pattern
  OF e xxx.emp_work_patterns,.
  DL curDateList (pi_start_date, pi_end_date)
  WHERE dl.when = e.roster_date
  ORDER BY e.roster_date;
  
  (Needless to say that queries are much more complex and many!)
  
  I reached the required result by using the pipeline table functions that just open the first cursor and run each line, but am frequently end up using multiple nested functions to achieve and I see marked in this way, then the performance degradation that comes to nest queries within the other runs a lot faster. As a nested query is just a nested cursor, it seems that this is possible, but I'm not only have no chance - I am struggling to find something that says that it of possible or not (which made me think I am barking the wrong tree here!)
  
  Any help would be greatly appreciated.

  No, it is not possible, but have you thought of creating a view instead?

• 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.

  Hi Srikanth,

  1. first create a datablock (better do instead of the table because its only for querying details of table 1 for the period) with table1 as table base and better use order by clause in form as "order to barcode, date, bartime.

  2. create a second datablock with table2 and get this rank on the two table (second block as base table, because here, you should insert/update)

  now on the screen you can see all the data in 2 tables.

  3. fix the button of some process.

  a time-but-press

  Loop

  1 block of travel and take a line

  Find the same block 2

  If code in bars-avail so
  -you want to update
  on the other
  -you want to insert

  end if;

  end of loop

  and 2nd block will be updated / inserted as u desire, and finally, you can save the second block.
