• How to select the last 20 transactions in a table

  Hi guys,.
  I have a table named INOUT with following columns
  
  EMPLOYEECODE VARCHAR2
  DATE OF THE RESPONDENT
  
  
  each day employees now their me 'in '. then entered came and came in this table. If we want to select the last 20 EMPLOYEECODE in this table that make their selves 'in '. How to choose that? just 20 last employees who traded. Help, please

  Hello

  This is called a Query Top - N , you want to choose elements of N (N = 20, in this case) from the top of a sorted list.
  Here's a way to do it:

  WITH     got_r_num     AS
  (
       SELECT       emloyeecode
       ,       MAX (intime)     AS latest_intime     -- If wanted
       ,       RANK () OVER (ORDER BY  MAX (intime)  DESC)
                      AS r_num
       FROM       inout
       GROUP BY  employeecode
  )
  SELECT     employeecode
  ,     latest_intime          -- If wanted
  ,     r_num               -- If wanted
  FROM     got_r_num
  WHERE     r_num     <= 20
  ;
  

  That actaully could take more than 20 people: If there be a tie, it includes any person who is entitled to be in the top 20. If you want exactly 20 people, then add the columns of tiebreaker to analytical or use ROW_NUMBER instead of RANK ORDER BY clause.

• How to identify the last instance of a dynamic table row

  Hi all

  I'm trying to figure out how to create an action for my form in Livecycle Designer ES2, which will affect the last instance of a dynamic table row. I have a table with a repeatable row where the user will enter information about a part purchased and I have buttons that allow the user to add and remove the lines. I need to create a line extra addition button which will add a new instance of the repeatable table line (this is not a problem) and disable and change the background color of the first cell in the row added. The problem I have is how to have an action that affects the last instance of a line.

  If anyone knows how to do this in Javascript, I would appreciate some advice/help.

  Hello

  I think that it is beyond providing an action. You will have a need to write JavaScript directly.  When you call the addInstance method it returns the new line, if you can do something like;

  var line = Table1._Row1.addInstance ();

  line. TextField1.border.fill.color.value = "255,0,0";

  line. TextField1.access = 'protected ';

  To find the last line and do the same thing, you can do something like;

  var line = Table1.resolveNode ("Row1 [" + (Table1._Row1.count - 1) + "" "]" ");

  line. TextField1.border.fill.color.value = "255,0,0";

  line. TextField1.access = 'protected ';

• Need to retrieve the last line/record in a table

  Hello
  
  I have a requirement like getting the ending balance of the last record in the table and the same insertion in the opening balance of the immediatetly created the next record.
  
  In simple terms, I need to extract a value from the last line of the recording.
  
  For example, I use the query below
  
  Select rownum emp, empno, ename
  where rownum = (select count (rownum) from emp);
  
  But, the above query does not return all of the recording.
  
  Therefore, need help on this.
  
  Kind regards

  Hello
  Strictly speaking there is no such LAST or FIRST folder until that order you them.
  But check the following:

  SELECT * FROM emp MINUS
  SELECT * FROM emp WHERE rownum<=(SELECT count(empno)-1 FROM emp);
  

  Kind regards

• How to view the last element in a dynamic table 1 d

  Hello..

  I want to display the value of the last element in a dynamic array 1 d... / I mean... If I stop the vi race, I need to display the last element of the array... How can I do this?

  and is it possible to use a button to start the vi... instead of using the Run button on the face before of the vi?

  An array of index!.  Size of table allows to determine the size of your array, subtract 1, that feed into the terminal array of Index index.

  You start the VI running somehow.  It can be assigned to run when opening.  Assuming that what you want is a way to type values in a front panel, press a GO button you created on the front panel, then have the real part of the VI to run.  You can use a structure of the event.  Or put a while loop at the beginning with a small wait next statement which basically just asks the GO button.  When you press this button, the Boolean value true stops the whole loop and allows the program to move on the main body of your program.

• Select the last 50 closed records

  The research of a statement select simple sql which selects the latest 50 records closed in the database.
  
  I found some help out there who have an example like:
  
  SELECT RecordID, closed_date
  (SELECT RecordID, closed_date, RANK() over (ORDER BY closed_Date DESC) date_rank
  FROM table1)
  WHERE the date_rank < = 50;
  
  Only problem is, this is to select something like 4000 recordings, and many of them are not yet closed.

  I think that you need to retrieve the records that are only closed in the first place.

  Try this,

  SELECT RecordID, closed_date
    FROM (SELECT RecordID,
                 closed_date,
                 ROW_NUMBER () OVER (ORDER BY closed_Date DESC) rn
            FROM table1
           WHERE closed_date < SYSDATE)  --Notice this.
   WHERE rn <= 50;
