• 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.

• by the way the variable counter between the loops

  I have a question about the passage of a variable counter between different events / while loops and seen an increase in value regardless of the loop is initiated.

  The fundamental problem is that I write file names unique to data collected on a spectrometer, and I would value at the end of the name of the file to increment every time that I collect the data. There are several different ways that I can collect the data, and I'd like the counter to increment when the collections is triggered. The attachment shows essentially what I'm trying to accomplish. Represent it buttons collect two different types of data I collect my instrument, but the counter variable is not passed correctly between the two loops. Is it possible that I can get the incrementing counter so that the two loops read the same value of counter?

  Thanks for your help.

  I can't look at your code since I'm on a phone. But you should really only have / need a structure of the event in a vi. The only exception I can think of is one to manage the events of the user and the other for GUI events. But even in this case there is no reason that I can think to need two.

• LabVIEW parallel for loop and OpenMP

  Hello:

  It's just a curious post, I just learned about OpenMP and I found that OpenMP helps you to parallelize loops in c about the same way that you can use the loop For parallel in LabVIEW.

  The loop For Parallel LabVIEW is being implemented under the hood using OpenMP? Or is it just a coincidence?

  No, it is not implemented LabVIEW parallel for loop under the hood using OpenMP. You might be interested to read this article on modern developments in the LabVIEW compiler architecture. Specifically, in this case, it's the DFIR technology discussed here that facilitates parallel for loop transformations.

• Cursor for loop and IN LOOP

  Hi gurus,
  
  I'm going to the table like this:
  
  TEST

  NO      PK
  VALUE

  And I wrote a test cursor procedure to retrieve values such as:
  

  CREATE OR REPLACE
  PROCEDURE test_proc_cursor
    (
      p_no OUT test.no%TYPE,
      p_value OUT test.value%TYPE)
  AS
    CURSOR proc_cursor

      dbms_output.put_line(p_no||'       '|| p_value);
    END LOOP;
    CLOSE proc_cursor;
  END test_proc_cursor;

  But, my question is, I have used the simple LOOP in the cursor. Anyone can write the same logic of cursor with all IN LOOP and LOOP FOR it please

• loop () and functions

  Hello
  I'm having a hard time getting past this little problem. I know its possible, but I hit a mental void.
  
  Here's the scenario:
  I have 14 items that I want to spend on the screen with an interpolation function. IM using a loop for () to invite each object, but I'm stuck here. I don't know how to call each object of this loop with a function.
  
  

  Sketchsta,

  > OMG!
  > Do you know what the problem was? ... you will laugh!
  > I had my randTime Math.round Math.random instead of variable... =)

  Heh, I saw that too, but failed to point this out in my follow-up
  suggestion). Oy. Glad you taking!

  > I thought actually separate topic of X and Y variables.
  > I guess that I expected it would generate a new number when

  The way in which your original code has been written, it wouldn't. You put
  the value of randPos once, then passing that as a parameter (a single
  parameter) to another function. As soon as you set the value of randPos, it
  only has the value we have. Until you set it again, what is happening on the
  next iteration of the loop for () (after the two your _x and FLF properties)
  were already interpolated).

  Cool. Even easier then.

  It is not necessary.

  Luck of the draw!

  > What are the benefits of coding in this way?
  > In addition to the code hints thing!

  In my view, indicators of code is useful and a good enough reason. Another
  advantage, in AS2, is improved at compile time error messages. If you type a
  variable number (because it is supposed to be a number) but accidentally
  Set it to a string (or some other type of data), the compiler is more likely to
  do you know that. It is not perfect, but it helps.

  In AS3, typing strongly has even more benefits, because it helps to reduce
  the overload of the RAM of your SWF file. This is because as the AVM2 (ActionScript Virtual
  Machine 2) Flash Player 9 and higher is smart enough to not ask the
  memory each strongly typed object needs. Otherwise, as in AS2, each new
  object instance needs enough memory to manage everything that type * could * be.

  It is logical, and here's why. Variables are declared inside the
  your function explode(), i.e. that explode() function made their home.
  The main scenario does not see these variables and can't nor any other
  object outside the service. Scope does not work in this direction: only
  from outside to inside. Which means, you can declare a variable in the main timeline
  and 'see' inside explode(), but not vice versa. It's
  why I added the third variable to sparkF().

  No, not pathetic. Do what works, right? This is the way of Flash (and I have
  means that with affection for Flash). But it is often easier to change one
  some numbers somewhere, having to keep moving symbols of trial and
  error.

  Hello

  Simply create a TYPE for strong cursors, returning the specified columns. For genereic, or the low sliders, there is a TYPE integrated, namely SYS_REFCURSOR.

  Try this:

  CREATE OR REPLACE function test_f(p_DEPTNO  in emp.DEPTNO%type)
    return SYS_REFCURSOR
    as
       REF_C     SYS_REFCURSOR;
  BEGIN
       OPEN  REF_C  FOR   SELECT  *
                           FROM    EMP
                    WHERE   DEPTNO = P_DEPTNO;
       RETURN REF_C;
  END;
  

  You don't want to close the cursor service.

  Always format your code.

• For loop and access objects by the instance name.

  Hey guys,.

  What I'm trying to do should be very simple, I want to make several non-visible movieclip objects using a loop for.

  Here is what I currently have...

  for (var i: Number = 1; i < 8; i ++) {}

  high [i] .visible = false;

  }

  I have therefore 8 movieclip objects that have names of "high1" instance, "high2", "high3" and so on until 8

  What is the syntax correct for this line of code to make this work?

  high [i] .visible = false;

  Thank you.

  You can use string to instances of the target values, if you use the support rating:

  for (var i: Number = 1; i<8;>

  This ["high" + String (i)] .visible = false;

• Variable binding in the procedure and function

  Hello
  
  I started reading ORACLE 11 g R2 PL/SQL programming doc and I'm stuck to bind the variable. I just copied the example in the books and found error-
  
  First of all, I wrote the procedure below and compiled with - success
  

  CREATE OR REPLACE PROCEDURE FORMAT_STRING ( string_in IN OUT VARCHAR2) AS
  BEGIN
   string_in := '[' || string_in || ']';
  END FORMAT_STRING;

  Then I wrote below function and also compiled successfully-

  create or replace function join_strings  (str1 varchar2, str2 varchar2)
  return varchar2 is
  begin
    return str1||' '||str2||'.';
  end;

  Later, I wrote the code below in the SQL Editor and found the ORA-00900 error. Please help me to understand.

  variable session_var varchar2(200)
  call join_strings ('I Love','you') into :session_var;
  call format_string(:session_var);

  variable session_var varchar2(200)

  If you want to do it in PL/SQL, you can use an anonymous PL/SQL block like that.

  set serveroutput on
  declare
    session_var varchar2(200);
  begin
    session_var := join_strings ('I Love','you');
    format_string(session_var);
    dbms_output.put_line(session_var);
  end;
  /
  

  If you want to run directly in SQL Plus you can do

  var session_var varchar2
  
  exec :session_var := join_strings ('I Love','you')
  
  exec format_string(:session_var)
  
  print session_var
  

• CURSOR for loops or an associative array

  I just want to know the advantages and disadvantages of the CURSOR for loops. As a general rule, what guys do you prefer: associative array with CURSOR for loops?
  
  
  If you use the CURSOR for loop, is it not difficult to debug?
  
  PL/SQL Developer, I do not see what values are stored in the CURSOR for loop (in SP master_proc below) as
  There are no variables to watch. Not sure if the TOAD can show these values
  
  If I had used an associative array (master_proc2 below), I can see the values stored in the table by clicking on "show Collection"variable in PL/SQL developer.

  Thank you Tubby. If you are faced with a situation where you MUST use a loop. Then you would go to associative arrays rather than CURSOR FOR loops. Right?

  Doesn't happen too often, but if/when then I would do as I said in my first post. Use the transformation, the collection table in BULK and FORALLs.

  If we use your example posted, I would NOT spend a single table (in a loop mode) value I would be transmitted in the OVERALL picture and treat it with FORALL.

  So, I would still use neither of the approaches that you mentioned.

  A parallel FOR loop has an overhead for parallelization (split the problem, then go back the results, etc.). If the code is very fast, the overhead is proportionally larger. If the Subvi takes a long time to complete, the overhead of parallelization is insignificant. It is often not worthwhile to parallelize the loops with a very simple and fast code.

• parallel processing: for loop taking place

  Hallo,

  I have a loop 'for' runnin on this system: LabVIEW2009, windows7, intel i7.

  I wonder if and how I can tell to LabVIEW that he would be allowed to run different iterations of the loop at the same time (concurrently) on my processor with 8 cores.

  Now, it will execute the next iteration when it ended the previous, even one so is there no dependencies in iterations.

  I want to give a 'ownership' of the loop, which means that it can be "unfolded" for parallel execution.

  Thank you

  pop up on for loop and select "configure interation Prallelism."

  Activate it.

  Wire a certain number to the new 'P' of entry to specify how many processors to spread it everywhere.
