• PL/SQL fetch statement.

  Hi guys,.

  I am a DBA and I have fair knowledge of PL/SQL. My developer argues me with code where he says he becomes RANK NEXT in each adverse FETCH that he wrote after the first FETCH statement below. He uses a lot these its FETCH to get the row in a cursor that has 17 million lines, too in a loop after extraction, for the first time. My understanding is if extraction is going to give you all of the defined file as returned by the cursor, unless otherwise stated. Please let me know if I'm correct, and how can I make him understand this.

  -Open the cursor

  Open c1;

  
  -Read the column header record then record of first data

  Fetch c1 into Field1, Field2, field3, field4 sphere5.

  -IF found THEN % c1
  -fetch c1 into Field1, Field2, field3, field4 sphere5.
  -END IF;

  -Loop main most project files.

  < < draft_loop > >
  While c1% LOOP

  OK_flg: = TRUE;
  Caution_flg: = FALSE;

  -- NEW INPUT RECORD --------------------------------------------------------------------------------

  IF field2 = n THEN

  -Save data recording N

  rec_serial_no: = TRIM (field4);
  rec_agent: = TRIM (field5);

  -Read the next record

  Fetch c1 into Field1, Field2, field3, field4 sphere5.

  ON THE OTHER

  OK_flg: = FALSE;

  dbms_output.put_line('ERR01:)) Current type is not TYPE = N: line =' | Field1 | ' Type =' | Field2);

  END IF;

  -- SOLD INPUT RECORD ------------------------------------------------------------------------------

  IF field2 = the of ' OK_flg AND THEN

  -Save the file S

  rec_amount: = to_number (sphere5) / 100;
  rec_sold_text: = TRIM (field4);
  rec_sold_date: = to_date (field3, ' dd/mm/yyyy hh24:mi:ss');

  -Read the next record

  Fetch c1 into Field1, Field2, field3, field4 sphere5.

  
  ELSIF Field2 = "C" AND OK_flg THEN

  -Save data file C

  rec_caution_date: = TO_DATE (field3, ' dd/mm/yyyy hh24:mi:ss');
  rec_caution_no: = TO_NUMBER (field5);
  rec_caution_text: = TRIM (field4);

  caution_flg: = TRUE;

  -Read the next record

  END IF;

  My question was however with the FETCH statement. I always thought that, as we open the cursor and then when we fetch we get whole dataset (can be limited to a few lines) and then we iterate through the value until we exhaust all what it several rows.

  A cursor is not a data group. A call to fetch is much more than a simple data extraction.

  SQL is the source code. The cursor is the binary SQL source code and compiled executable version. Want to see how this executable program, aka cursor looks like? See the execution plan. This explains the structure of executing this cursor/program.

  An extraction run this slider. It loads the cursor to run, to find the rows (one or more) and then return rows found in the appellant. This explains, for example, "snapshot too old" - as when the cursor is (yet) run by an extraction, the cursor code cannot find all the lines that the version of the data, the cursor is responsible for finding, has now ceased to exist as the said container version redo buffer has been replaced.

  If the cursor is a dataset that was built, what memory would hold this dataset? How this scale there are 1000's of opening sessions several sliders and each cursor requires a piece of memory of the server for all of its data?

  This is not a method that would be globally, or deliver any kind of performance.

  The best place to perform cursor processing is in the SQL engine. For example, your code example uses a cursor to read. The cursor is driven out of PL/SQL. The output of the cursor moves the engine SQL in variables of fetch in the PL/SQL engine. Then, the code example uses one or more write cursors - return the values of recoveries in the PL/SQL engine to the SQL engine. Data will leave a cursor to another cursor via a detour of PL/SQL. Why? This can NEVER evolve.

  If instead you use a single slider to perform both read and write, the data doesn't have to travel via PL/SQL from reader to writer - as this unique time cursor reads and writes data. And because it's a stand-alone cursor, it can also be run in parallel when it comes for example from large chunks of data via a full table scan.

  Opening a cursor in PL/SQL, browsing this slider in PL/SQL, data retrieval of this PL/SQL cursor - wrong most of the time. It's the 80's style COBOL record-by-record processing. An exception to the rule when it comes to databases, datasets and SQL data processing language.

           END
  WHERE  prov_dec_for_tax IN ('AB', 'NT', 'YT', 'NU', 'NV', 'QC');
  

  Just add several WHEN clauses and include in the list of in WHERE clause.

• read and write cursor properties

  I am trying to copy the property x position of two sliders of a XY Chart to a curve of intensity or vice versa.  I have the index through a list of cursor to deal with two cursors.  I have attached a VI to illustrate the problem. It works well the way the XY graph to the curve of intensity: enter either the cursor on the top graph, move, and it moves to the same position in the graph on the bottom.  If you take a slider on the bottom graph (intensity), it works very well for a slider, but the other curor is moving at x = 0.

  (I should mention, the problem is a little different after the closing and reopening of my VI.  When I first wrote the VI, the sliders in the top graph did not at all when I moved the low graphic cursors.)

  

  Do not lock the cursor in a field, especially if the graph data. Works very well with free dragging sliders.

• TDMS write to the auto folder causes the flicker of the cursor

  I joined a project (8.6 LV) showing this problem.  When writing to a TDMS file in a folder of automatic settlement, the cursor briefly becomes a hourglass.  This behavior is not seen when a folder is not monitored by LabVIEW project through AutoFill.

  Run the VI.

  Toggle "Auto" true and wait 10 seconds to see flicker.

  Toggle the 'automatic' to False and flicker settlement stops.

  -Jason

  Hi Kyle,.

  In the forum you referenced, issue of mvickerman on the flicker of the cursor centered around closing and rinsing of a file.  The real cause is that the file operations are conducted on a file that resides in the LabVIEW project folder was auto.  I started a new thread to document the question more directly where others see a similar problem (writing to a file and see a flicker of the cursor).

  If the flicker that bothers someone, during development, they can stop automatic settlement on the record with the data file or manually include the data at the root of the project file.  Despite what says the solution on this forum, the problem doesn't seem to be the data file being simply in the project, but in a case of automatic settlement.

  As I said there:

  «For the record, I always choose to use automatic settlement files.»  I built the demonstration project to prove to myself that automatic settlement of records caused the problem.  Like most, we build applications (exe) for the customers, and data files are not in the hierarchy of development.  Besides, the customer have usually the LabVIEW project open if they have LabVIEW at all.

  Thus, the problem with deployment. »

  Take care

• When you write a sentence the cursor jumps at the beginning if I type too fast

  If I type too fast or even at a moderate speed my cursor jumps at the beginning or in another part of the sentence.  I type very slowly in order to complete a sentence.

  I'll guess that you are using a laptop with a touchpad? If Yes, go to control panel > mouse and then look for a tab that relates to your touch pad and then see if you can adjust the sensitivity. Chances are that you are hit while you type.

  I hope this helps.

• Firefox has crashed on the desktop. Get only the black screen, taskbar with icons and hourglass cursor of the mouse on the taskbar. Windows 10.

  I tried to restart Firefox, nothing helps. Then I tried to restart my desktop computer Dim screen with taskbar with icons, hourglass cursor that does nothing on tasckbar only. I tried to close everything down and restart - without success. I write from my laptop, the problem is on my desk - Hewlett-Packard, 2-3 years, running windows 10. Only one prior occasion when Firefox crashed. Restart of Firefox took care of the problem and has been fine since.

  Contact a computer repair. It seems that the system files are corrupted.

• All of a sudden, when I try to write, to answer before msg, msg window is empty and I don't see any entrance of typing.

  When I turned on my computer this morning everything was normal. Then, after the use of Firefox by email some time I tried to reply to another email. When I hit the button the screen answer answer did not contain the text of the email that I answered. Also, it does not show the cursor. I've tried several things, including research help files all to nothing does not. So I tried to write a message. Same indication then I tried to type data. Nothing showed on the screen, so I sent it to myself. When I received the note, the text I got tyoed appeared and it looked normal. So I tried to reply to the same message. In its response, mode, the electronic part of the screen was blank, so I typed the text extra, always invisible and sent it. Upon receipt of the message, all the new text is there. Same thing when I try to send a message. All data is invisible on the screen forward, but everything I type in the message is present when I get the message.

  Thanks for the note and the suggestion. I'll save it for "next time" if she comes back. Before the entrance of your note, I tried something.

  A few moments ago, I tried something. I ran the free version of Malwarebytes Anti Malware and found 79 "threats". They have a lot of;
  Pup.Optional.Wajam.A, Pup.Optional.CrossRider.A, etc. Several others with different names after the Pup.Optional... I've quarantined the and again tested the response functions and the attacker. They now work as they are supposed to. It seems therefore that the problem was caused by these UN wanted malicious elements. All were in the library of Thunderbird.

• Text cursor appears everywhere where you click

  Everywhere I click the cursor appears I will write something. Idk if I was doing something or something has changed, but it's a little boring. I can't noticed this before for awhile but today I was. It seems that every time I click at the beginning of a line. I have not changed a thing on my Firefox settings for the longest of time. The only thing I had to do was reset recently how I wanted to search for updates and he even returned to it's setting, I got it on front.

  So is this a part of Firefox which is just now attracts my attention or did something to change?

• Satellite P300 - cursor jumps back

  Hello

  I have a Satallite P300 - 19 p and when I type after some works the cursur jumps to a place randomly in the text that I write. Is very annoying because I have to look at the screen all the time, I tried to type very slowly to see if I tap on a button by accident, but then it never happens.

  If anyone knows if it is a fault, all other computers that I use if I hit a wrong key, I just get a bad character not the cursor jump to a point prior to writing

  Hello

  I think you touch the keyboard as you type and so the cursor jumps to another post.

  Therefore, you must disable the tapping function in the touchpad driver. After that, you can only use the touchpad for moving the mouse but not for the left clicking (tapping) more.
  Check Control Panel > mouse > advanced settings.

  Here, you can disable this feature.

  Check this box!

• Re: Inaccurate cursor when using the stylus on Portege M700 Tablet mode

  Hello

  I was struggling with my stylus for a few months. When I use it, the cursor is just the tip, when I'm in the corners (where the calibration takes place). More central that I get on the screen, more it is. We're talking about half a centimeter, which does not seem a lot, but that can be a real pain if you try to write or draw on the screen.
  The tragic part is that it started AFTER I used the tool of calibration for the first time. If I had known that it makes things worse, I would not have touched him.
  My question is: is there anyone out there with the same problem, or is it unique? If this is the case, I'll have a conversation with my dealer after I go home.

  If it is not unique, how this was dealt with?

  My laptop is a Portege M700, with Windows Vista Business SP1. This issue has been consistent through all kinds of situations, hardware configurations and software content, and the starting point was obviously the calibration.
  I thank in advance anyone who can shed some light on this for me.

  Best,
  Oliver

  You're calibrating with the stylus on an angle?

  Try it with the completely vertical stylus.
