• 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.

• I installed a trial of Illustrator from Adobe on my macbook pro. I want to draw a picture using the custom trace button but can not. Does anyone have any ideas how I could track custom?

  I installed a trial of Illustrator from Adobe on my macbook pro. This is the release of 2014 of the adobe Illustrator. I want to draw a picture using the custom trace button.

  I start a new document. Then I place my scanned pencil/color pencil, drawing, in the document. I tried to scan and then placing it as jpeg, bitmap and a tiff file. I tried scanning and place then, in color and in black and white. The scan mode that I use is flat. Adobe Illustrator allows me to select the default button and one of the eleven preset buttons (e.g. photo high fidelity), but cannot me click on the record button custom. The custom trace button is gray while all other buttons are white.

  Does anyone have any ideas how I could track custom?

  Just it trace, and then change the options later. The follow-up is 'live', you can press the buttons and see what happens.

  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.

  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.

  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.

• Where are the pictures stored when taking a picture using the Microsoft Lifecam HD 6000?

  Microsoft lifecam hd 6000 image storage

  Hi all

  Does anyone know where the photo store, after I take photos using microsoft lifecam hd 6000?

  Thank you.

  You can check if the pictues were stored in the folder %Temp%.

  Click on Start and then run.

  In the text box on the run window, type %temp% , and then click OK.

  A folder full of files and other folders will appear.

  You can search by the date field for the day that you were using your WebCam. If the pictures are not saved, you can search for them by name. If you cannot find them by searching, photos no longer on your computer.

  If you want to increase the space available, all the folders and files that you see in this Temp folder are no longer used by Windows XP and can be deleted safely.

  To remove files or individual files, hold your Ctrl key while clicking on each item you want to remove. Release the Ctrl key when you are finished.

  To remove these items, press your delete key or choose file , then delete from the menu.

  Confirm that you want to delete the files by clicking Yes in the window to confirm deleting multiple files that opens.

  After all the files have been deleted, you can close the window and empty your trash, permanently remove the files from your PC.

  To ensure that the pictures of the webcam are saved for next time, you need to manually back up.

  Let us know if that helps.

• Cannot import pictures using the USB cable

  I have a Canon 5 d Mark III and LR 4.3. I normally import pictures using a card reader see However, I'm on vacation and have only the USB cable that connects the camera to my Macbook Pro. I used it successfully in the past to import photos, but I am now getting the following error:

  

  I get this if I select one or more photos (there are about 195 on the map right now).

  Any ideas?

  Often, this error message means that LR cannot write the file to the location you're trying to move/copy it to, usually because your permissions to the folder or drive do not allow writing. Also, make sure that you have property ot the disk/folder.

• 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;

• 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?
