How to retrieve a single value to an XMLTYPE

• Retrieve a single value from a file .lvm

  I have a large batch of files of worksheet whose name is a timestamp. I am writing a program that will get the value of a specific cell (the same cell in each file), coupled with the timestamp and each of them as a pair of coordinates, then save in a master spreadsheet. The goal is to extract a point each of the 700 files I and compile them into a single file.

  However, I've never used Labview to read the files before. I saw some stuff on how to read an entire worksheet in a table, but I was wondering if there was a way to say to Labview to look into a file and extract a single value. I open .lvm in Excel files, so, in my mind, I would be taking, for example, cell D2. Is this feasible? Should I read the entire worksheet in an array and use the index to pick it up on the table? If I do, how I would specify cell J2 as an array index (I have no experience with the berries in Labview either). In addition, if you have any tips on how to record easily 700 pairs of coordinates, that came together in the order, to a single spreadsheet, that is my next task.

  Essentially- I need to extract a single value of a spreadsheet in, ideally, the simplest possible. In addition, pointers on how to save the numbers gathered at each iteration of a while loop to a single worksheet are welcome.

  Thanks in advance for the help!

  FYI I have LabView v8.6

  You can't say LabVIEW to 'out' a specific 'cell' more you can tell Notepad to do. the .lvm files are just text files. When you open them in Excel, the column separator (default tabs) show to put the values in columns. In LabVIEW measurement file VI reading to read .lvm files. It creates the dynamic data, wrong data type that is next to useless. You will need to convert this type of data in a table by using the function convert of DDT. Or, you can use the VI read spreadsheet file. This will give you a table directly. You can just remove the specific item using the table to Index.

• How to write a single value in an excel spreadsheet

  Hello

  I use an excel spreadsheet, as if it were an external code module. He does a lot of calculations, all I do is write an individual value, let calculate what it should only then read a return value from this.

  I already have a structure able to read a table, but could someone help me with a piece of code that could write a single value?

  (To read a value unique too may be practical)

  Also, I have the new LabVIEW 2009, so while a fancy to drop some code here as one. PNG, it would be nice to see if this new feature works!

  Thank you, Alec

  Try this. There are 2 point methos (get) and point (put) to read and write the value respectively to a cell in excel.

  Good luck

  I'm guessing it's a bug fixed when Oracle 10.2 is released. I can reproduce your lack of results on 10.1.0.4 and as shown in my post above, it works correctly on 10.2.0.4.

  Here is a modification of the script that shows what is happening that I have that debugging. (It took me a bit to realize the difference that it wasn't what I was expecting)

  declare
     p_response_doc XMLTYPE;
     l_new_doc      XMLTYPE;
  begin
     p_response_doc := XMLTYPE('
  
  
  
  1163
  1103
  
  
  ');
     SELECT p_response_doc.extract('/*/*/*/CompliantOrgs','xmlns="http://www.example.org/ComplianceServices"')
       INTO l_new_doc
        FROM dual;
     dbms_output.put_line(l_new_doc.getStringVal());
     dbms_output.put_line('before loop');
     FOR r_rec IN (SELECT value(t) val
  --   FOR r_rec IN (SELECT extractvalue(value(t)
  --      , '/CompliantOrgs'
  --      , 'xmlns="http://www.example.org/ComplianceServices"' ) val
        -- BULK COLLECT INTO l_nm_array
        FROM TABLE(
          XMLSequence(
            p_response_doc.extract('/*/*/*/CompliantOrgs','xmlns="http://www.example.org/ComplianceServices"')
            )
          ) t
     ) LOOP
        dbms_output.put_line(r_rec.val.getStringVal());
  --      dbms_output.put_line(r_rec.val);
     END LOOP;
     dbms_output.put_line('After output');
  end;
  

  10.2.0.4 on this product

  1163
  1103
  
  before loop
  1163
  1103
  After output
  

  It produces on 10.1.0.4

  1163
  1103
  
  before loop
  1163
  
  1103
  
  After output
  

  As you can see, Oracle is to detach (well technically not add) the space of default names to the nodes retrieved. To compensate, you need to change your loop to look like

     FOR r_rec IN (SELECT extractvalue(value(t)
        , '/CompliantOrgs') val
  --      , 'xmlns="http://www.example.org/ComplianceServices"' ) val
        -- BULK COLLECT INTO l_nm_array
        FROM TABLE(
          XMLSequence(
            p_response_doc.extract('//CompliantOrgs','xmlns="http://www.example.org/ComplianceServices"')
            )
          ) t
     ) LOOP
  

  so extractValue does not expect the namespaces associated with the nodes.

  I would suggest you document it so that you know why things break if you upgrade to 10.2 or later at some point in the future.

• Best practices for retrieving a single value from the Oracle Table

  I'm using Oracle Database 11 g Release 11.2.0.3.0.

  I would like to know the best practice to do something like that in a PL/SQL block:

  DECLARE
    v_student_id    student.student_id%TYPE;
BEGIN
    SELECT  student_id
    INTO    v_student_id
    FROM    student
    WHERE   last_name = 'Smith'
    AND     ROWNUM = 1;
END;

  Of course, the problem here is that when there is no success, the NO_DATA_FOUND exception is thrown, which interrupts the execution.  So, what happens if I want to continue despite the exception?

  Yes, I could create a block nested with EXCEPTION section, etc, but it seems awkward for what seems to be a very simple task.

  I've also seen this handled like this:

  DECLARE
    v_student_id    student.student_id%TYPE;
    CURSOR c_student_id IS
        SELECT  student_id
        FROM    student
        WHERE   last_name = 'Smith'
        AND     ROWNUM = 1;
BEGIN
    OPEN c_student_id;
    FETCH c_student_id INTO v_student_id;
    IF c_student_id%NOTFOUND THEN
        DBMS_OUTPUT.PUT_LINE('not found');
    ELSE
        (do stuff)
    END IF;
    CLOSE c_student_id;   
END;

  But it still seems to kill an Ant with a hammer.

  What is the best way?

  Thanks for any help you can give.

  It depends on what you want to do.

  You expect only 0 or 1 rank. SELECT INTO waiting for exactly 1 row. In this case, SELECT INTO may not be the best solution.

  What exactly do you do if you return 0 rows?

  If you want to set a variable with a NULL value and continue the treatment, Frank's response looks good, or else use the modular Billy approach.

  If you want to "do things" when you get a line and 'status quo' when you don't get a line, then you can consider a loop FOR:

  declare
    l_empno scott.emp.empno%type := 7789;
    l_ename scott.emp.ename%type;
  begin
    for rec in (
      select ename from scott.emp
      where empno = l_empno
      and rownum = 1
    ) loop
  l_ename := rec.ename;
      dbms_output.put_line('<' || l_ename || '>');
    end loop;
  end;
  /
  

  Note that when no line is found, there is no output at all.

  In short... you can't.  The channels are channels, and SQL and PL languages dictate that the string literals are provided within single quotes.

  I don't see how trying to retrieve more than 200 records of employees in the select statement means that you must get rid of the quotes.

• How to retrieve a value of page element in another page?

  Hello
  
  How to retrieve a value of page element in another page?
  
  say P55_COURSES_TO_EVALUATE is my name of the page element, and it is a selection list. Based on the value selected in the next page I see the details of the selected value shd and for that I need P55_COURSES_TO_EVALUATE value in the following page. How to do it? When I try to retrieve the values it simply returns nothing.
  Pointers would be really useful.
  
  Thanks in advance.

  Hello

  Could you please how you try to use it?

  If you set the value to the P55_COURSES_TO_EVALUATE element and submit the page, the value is stored in session state.
  Then you can use this element in any page as

  :P55_COURSES_TO_EVALUATE
  

  You cannot access page value in javascript/jQuery to other pages like

  $v('P55_COURSES_TO_EVALUATE')
  document.getElementbyID('P55_COURSES_TO_EVALUATE')
  $(#P55_COURSES_TO_EVALUATE)
  

  Because the item is not on the other pages. In javascript from other pages, you can use

  var a = '&P55_COURSES_TO_EVALUATE.';

  You can change your current password as follows:

  1. click on start.
  2. type the three letters cmd in the search box.
  3. press on Ctrl + Shift + Enter
  4. click on "run as Administrator".
  5. type the following command and press ENTER after each:
  NET user "user %%nom" 123456

  Now the password is 123456. While dealing with accounts and passwords: having a single admin account on a PC is about the same as having a unique key for your car. What happens if you lose? He lost? Break it? A robust Windows Setup requires at least the following:

  • Two admin accounts fully tested, with their passwords to record on paper.
  • A password key file. Click Start / Help, then search for help on "password". Follow the instructions to create a key on your USB flash drive file so that you'll never find yourself in this uncomfortable situation.
