• only the update by removing for cursor loop

  Hello

  I have the cursor for loop below update a flag. Need to convert the single update by removing the loop.

  po_date po_number BLACK flag

  123 123 - 1 12 December 2015

  123 123 - 2 December 15, 2015

  123 123 - 3 December 21, 2016

  Result

  =====

  po_date po_number BLACK flag

  123 123 - 1 12 December 2015 MUL

  123 123 - 2 15 December 2015 MUL

  123 123 - 3 December 21, 2016

  So, if there are several BLACK for a PO_number, then Mark flag = "MUL" for the two records which are min as the max po_date.

  I'm in select * from alm_po_quotes

  loop

  Update alm_po_quotes

  flag of the value = 'MUL '.

  where po_number = i.po_number

  and

  po_date < (select MAX (po_date) in the alm_po_quotes where po_number = i.po_number);

  end of loop

  Please notify.

  Thank you

  In your update, simply add the clause as below

  -Statement to merge

  MERGE INTO alm_po_quotes apq

  USING (SELECT MAX (po_date), mxpo_date,

  APQ.po_number

  Of alm_po_quotes apq

  GROUP BY apq.po_number

  ) q1

  WE (apq.po_number = q1.po_number

  AND apq.po_date<>

  UPDATE SET apq.flag = 'MUL '.

  ;

  -Update statement

  UPDATE alm_po_quotes apq SET apq.flag = 'MUL '.

• Avoid calling the procedure in the cursor loop

  Hi all
  
  The following example of procedure the procedure written in cursor loop, is called each time until the end of the cursor loop...

  procedure proc_main is
  DECLARE
   cursor c1 is 
      select e.empno empno
             ,e.ename ename
             ,d.dname dname
             ,d.loc   loc
      from emp e,dept d
      where e.deptno = d.deptno ;
   
  BEGIN
    for i in c1 LOOP
     proc_test(i.empno,i.ename,i.dname,i.loc) ;
     end loop;
  END;
  -----------
  
  PROCEDURE proc_test (p_empno,p_ename,p_dname,p_loc) is
  ---
  ---
  begin
   select * into v1,v2,v3 ..
    from temp_tab
     where col1 =p_empno
      ----
      ----
  
  end;

  What would be the alternative methods to write the procedure above instead to call the procedure inside the cursor for loop
  My idea is to use collections... could you give me the code example using collections to meet the above criteria
  
  Thank you

  The ideal would be to collect all SQL logic and put as much of it in a single SQL statement as possible. It would be also great to determine what is the final outcome of the process and use it as a starting point for your SQL. For example, if the desired result is to upgrade the salaries of the employees where they have an entry in table x, you might find that you can avoid needing to separate the logic between multiple, i.e. instead of procedures

  procedure proc_main is
  DECLARE
   cursor c1 is
      select e.empno empno
             ,e.ename ename
             ,d.dname dname
             ,d.loc   loc
      from emp e,dept d
      where e.deptno = d.deptno ;
  
  BEGIN
    for i in c1 LOOP
     proc_test(i.empno,i.ename,i.dname,i.loc) ;
     end loop;
  END;
  -----------
  
  PROCEDURE proc_test (p_empno,p_ename,p_dname,p_loc) is
  ---
  ---
  begin
   select * into v1,v2,v3 ..
    from temp_tab
     where col1 =p_empno
      ----
      ----
  
      UPDATE
          emp e
      SET
          sal = v2
      WHERE
          e.empno = p_Empno;
  
  end;
  

  You may simply have

  procedure proc_main is
  BEGIN
  
      UPDATE
          emp e
      SET
          sal = ( SELECT
                      t.new_sal
                  FROM
                      temp_tab t
                  WHERE
                      t.empno = e.empno
                 )
      WHERE
          EXISTS
              (   SELECT
                      NULL
                  FROM
                      temp_tab t
                  WHERE
                      t.empno = e.empno
              );
  
  END;
  

  Even if your logic is more complex, you are likely to find that you can merge several of the statements that you could be running in a loop and replace that loop with a join.

  Given the particular structure of what you posted if, instead of calling the procedure in a loop, you can simply move the cursor c1 as a parameter to proc_test that is

  procedure proc_main is
  
      lc_c1   sys_refcursor;
  
  BEGIN
  
      OPEN lc_c1 FOR
      select e.empno empno
             ,e.ename ename
             ,d.dname dname
             ,d.loc   loc
      from emp e,dept d
      where e.deptno = d.deptno ;
  
     proc_test(c1) ;
  
  END;
  -----------
  
  PROCEDURE proc_test (p_Cursor sys_refcursor) is
  
  begin
  
      LOOP
          FETCH ....
  
          ...DO SOMETHING...
  
          EXIT WHEN p_Cursor%NOTFOUND;
  
      END LOOP;
  
      CLOSE p_Cursor;
  END;
  

  But I highly recommend that you consider trying to merge as much of your SQL before considering the approach of cursor.

• Possibility to use the Enum control as an index for the loop entry For

  Hello world

  I'm curious to know if an ENUM type could be an index entry for a loop For (in fact, I tried in labview but it did NOT work).

  I use Enum to my two configurations (only two elements), but sometimes I need to run the two together.

  I wonder if it has a good structure to manage it, or simply replace ENUM with table.

  Thank you

• TestStand blocks by "for each" loop

  TestStand crashes from time to time for unknown reasons. We believe that 'foreach' loops could be the reason. By replacing the "for each" loop with a loop and iterate using the index, the problem is solved.

  Is this a known problem in Teststand? Is it possible that this is resolved in Teststand 4.1 (we use 4.0.1)?

  Kind regards

  This looks exactly like a previous problem (98902) report, which has been fixed in 4.1.

• Why loops run after that assignment of processors for timed loops?

  I have 256 call loops of two frames in my code. When I execute the code without affecting processors only 128 call loop runs at the same time, however when I attribute a different processor to each of them (0-255) then only 4 runs at the same time. Why is this? How can I make all run simultaneously?

  Attached: two snapshots of the code. 1 shows a small portion of the call loops, and the other is the part of code that communicates with an FPGA VI which controls the status of the outputs (using a CRio-9066.) For call loops, the small Sun icon is a Subvi, which generates values for the time delay dt call loops.

  doug333 wrote:

  They run on the computer VI and I don't know how many processors available I!

  Windows?  If this is the case, don't bother with call loops.  They add overhead and you're very unlikely to get something from him.  Even basic affinity rarely helps.  Normal just use While loop with a ms funtion in here waiting.

• write 1 d digital table in a binary file and start a new line or insert a separator for each loop writing file

  Hello:

  I'm fighting with digital table of 1 d writeing in a binary file and start a new line or insert a separator for each loop writing file. So for each loop, it runs, LABVIEW code will collect a table 1 d with 253 pieces of a spectrometer. When I write these tables in the binay file and the following stack just after the previous table (I used MATLAB read binary file). However whenever if there is missing data point, the entire table is shifted. So I would save that table 1-d to N - D array and N is how many times the loop executes.

  I'm not very familiar with how write binary IO files works? Can anyone help figure this? I tried to use the file position, but this feature is only for writing string to Bodet. But I really want to write 1 d digital table in N - D array. How can I do that.

  Thanks in advance

  lawsberry_pi wrote:

  So, how can I not do the addition of a length at the beginning of each entry? Is it possible to do?

  On top of the binary file write is a Boolean entry called ' Prepend/chain on size table (T) '.  It is default to TRUE.  Set it to false.

  Also, be aware that Matlab like Little Endian in LabVIEW by default Big Endian.  If you probably set your "endianness" on writing binary file as well.

• Any built-in support for cursors on the graph and trend curves

  Hello

  I went through the documentation to verify that no support exists to draw trend lines and using the slider on the axis (bargraph) but could not find anything related to it. Can you please confirm if there is any built-in support for cursors/trend lines in the component ojchart (bar graph) of the current version of JET.

  Thank you

  Subhash

  Hi Adoni,

  Due to the large number of possible algorithms, we do not provide built in calculation for trend lines. Our goal is rather to ensure that the user can display trend lines what they calculated, with the right amount of interactivity support. We have a very basic demo of this feature in the Cookbook: Oracle JET - graphics - Custom graphics: trendline. In this demonstration, we recommend using reference objects, rather than additional series, because the objects of reference do not allow a user to interact with the individual points or use features such as selection or drilling, which would be undesirable for a trend line.

  On the second question, could you give more details on this cursor you are referring? We have two ways to use our zoom and scroll feature:

  • Preview: Oracle JET - graph - Zoom & scroll: the time axis
  • Simple scrollbar: Oracle JET - graph - Zoom & scroll: categorical axis

  Thank you

  On the one hand, you will leave this function in the first round,
  because you return the result inside the loop. Return immediately leave him
  function. On the other hand, I am tempted to move on to something more like
  this:

  for (var i = 0; i)<_item.cats.length; i++)="">
  iCat var = item.cats ;

  I had really bad luck to get for each to work the way I think that it
