• Calculate the maximum value of the sub-table when creating using a structure of case and records the shift

  I have two 1 d arrays that contain cyclical information (a bit like a sine wave).  One that contains information about the position in degrees and another that contains the couple.  I would like to calculate the value of maximum torque whenever the station is within a certain range (for example, 30 to 80 degrees).  The beaches are repeated - that is why it is cyclical.   I use the function "in the range", a structure of the case and the shift records to build a new table with the values that are included in the beach I said - that was easy part (see attached VI).  I'm struggling with a way to calculate a maximum value for each sub-table formed when the values are 'in range '.   Your help is very appreciated.

  vt92 solution worked!  I agree that there should be a simpler solution, but your to works fine.  Thank you very much.

• Calculate the average value

  the data that I measured changed quickly, so I want to get the average value of the data

  Don't tell me to use mean.vi, I already know.

  and I got an idea that is to add data in a table every time, then the sum of all value data and take the line of result by the number of items

  but I don't know how to do this, anyone can build a simple vi to show me? Thank you

  I enclose my vi that uses mean.vi to the average value of calc, you can remove it and help in your path, thank you!

  Do not add your data in a table that grows forever. What a waste of RAM. To calculate the average, you only need to sum and N.

  Here is a simple code to accumulate the sum of the values in a shift register and divide by the number of add operations.

  

• Not able to print the decimal values in a table

  Hi all

  I created an application. Here, I have a table with three columns Col1 and col2 are numbers and col3 is the diffrence between col1, col2.

  I use AJAX and JavaScript to calculate the difference in a dynamic way.

  I am able to print the difference as for example:-1, 2, 1.5-1.5. but not 0.8, 0.8, 0.1 etc...

  If col1 col2 = 1.2 - capable of printing

  If col1 to col2 = 0.2 - error, unexpected token

  

  -Code AJAX:

  Declare  
    p_curr  number;  
    p_prev    number;  
    p_diff number;  
  Begin  
    p_prev    := to_number(apex_application.g_x01);  
    p_curr    := to_number(apex_application.g_x02);  
    
     
    SELECT to_number(p_curr - p_prev) into p_diff  
    from dual;  
    
    -- return calculated value
    sys.htp.p(p_diff);  
  End;
  

  -JavaScript: running the loading of the page

  function f_calulate_duration(pThis) {  
  
    var row_id     = pThis.id.substr(4);  
    var s          = $('#f18_'+row_id).val().replace(/[^\d.-]/g, ''); 
    var curr       = $(pThis).val().replace(/[^\d.-]/g, '');

  ( "CALC_DIFF", { x01: prev, x02: curr }, 
  { success: function( pData ) { 
  $('#f23_'+row_id).val(pData);}}
  );  
  }  
  

  Please suggest the solution to this.

  Thank you

  Dev

  Hello

  I don't get the point to use the expensive AJAX call to the database, instead you can have the same functionality with JavaScript code below.

  function f_calulate_duration(pThis) {
    var row_id     = pThis.id.substr(4);
    var s          = $('#f18_'+row_id).val().replace(/[^\d.-]/g, '');
    var curr       = $(pThis).val().replace(/[^\d.-]/g, '');   
  
  if(!s){
    var s= 0;
    var prev = s;}
  else{
    var prev = s;}
  
  var diff = 0;
  diff = curr - prev;
  var n = diff.toFixed(2);
  alert(n);
  $('#f23_'+row_id).val(n);  
  
  //-- Remove this code
  /*apex.server.process
  ( "CALC_DIFF", { x01: prev, x02: curr },
  { success: function( pData ) {
  $('#f23_'+row_id).val(pData);}}
  );*/

• Calculate the elapsed time between the horodateurs log Table

  Hello

  I'm looking for some codes SQL allows to calculate the elapsed time between the timestamps in a log table.  The log table has some STOP-START operations.

  I just want to calculate the elapsed time between the START and PAUSE of Transactions, as well as START and EXECUTE transactions.

  So, in the example below, the time spent must be:

  START 09:15 break 09:20 (5 Minutes)
  START 09:30 to 09:45 (15 Minutes) FULL

  Total elapsed time for LOG_ID 1234 should be 20 minutes.  This excludes the 09:20 at 09:30 BREAK at the START time.

  LOG_ID	SEQ_NUM	LOG_TYPE_CD	CRE_DTTM
  1234	1	BEGINNING	09-15 - 2013:09:15:00
  1234	2	BREAK	09-15 - 2013:09:20:00

  Hello

  Thanks for posting the CREATE TABLE and INSERT.  be sure to post the results desired from these data.

  Hi thanks for the help...

  The date is a true timestamp.  ...

  Here's a sample of CREATE TABLE and a few inserts.  3 ID transaction, each with a series of journal entries.

  CREATE TABLE 'LOG_TABLE_X '.

  (SELECT 'ID' CHAR (14 BYTES) NOT NULL,)

  ACTIVATE THE "LOG_TYPE_FLG" TANK (4 BYTES) NOT NULL,

  ALLOW "LOG_DTTM" DATE NOT NULL

  );

  ...

  I'm so confused.  Is log_dttm a TIMESTAMP, you said in the story, or is it a DATE, as you say in the CREATE TABLE statement, or is it a VARCHAR2 as Thur INSERT statements?  I'll assume it's a DATE.

  I left out an important step yesterday.  The computation of the last_start, we need to use a CASE statement so that we record only the time of events STRT.

  Here's the revised query:

  WITH got_last_start AS

  (

  SELECT id, log_type_flg, log_dttm

  LAST_VALUE (CASE

  WHEN log_type_flg = "STRT".

  THEN log_dttm

  END

  IGNORES NULL VALUES

  ) OVER (PARTITION BY id - can - be

  ORDER BY log_dttm

  ) AS last_start

  OF log_table_x

  )

  SELECT id, log_type_flg, log_dttm

  , (log_dttm - last_start) * 24 * 60 elapsed

  , SUM (log_dttm - last_start) OVER (PARTITION BY ID.

  ORDER BY log_dttm

  ) * 24 * 60 AS total_elapsed

  OF got_last_start

  WHERE log_type_flg IN ("CMPT", "PAUS")

  ORDER BY id, log_dttm

  ;

  Output of your sample data:

  ID LOG_ ELAPSED TOTAL_ELAPSED LOG_DTTM

  -------------- ---- ------------------- -------- -------------

  1111 PAUS 09-26 - 2013:09:09:58.17.17

  1111 CMPT 09-26 - 2013:10:09:58 1.00.83

  2222 CMPT 09-26 - 2013:12:09:58 180.00 180.00

  3333 CMPT 09-26 - 2013:10:09:42 59.73 59.73

  In Oracle, when you subtract one DATE from another DATE, the result is the NUMBER of days between them.  In the above query, I multiplied the past columns and total_elapsed by the number of minutes per day (24 * 60), to show the time in minutes.

• Add numeric value in the column in the Table

  Hello
  My problem:
  I have a VO with a numeric attribute (Sal). This VO is present in a table in a JSF Page.
  I need to add a numerical value to the value of the column.
  
  I have try it with #{row.bindings.Sal.attributeValue * 2} or #{rank. SAL + 2} or #{rank. Sal.inputValue + 2} but I get an error.
  
  Can someone help me?
  
  Thank you
  
  11.1.3 JDev

  Hello

  one option would be to use a transitional attribute in the VO to calculate math or to fill in the field column of a managed bean. You can point the field for the column to a property of the managed bean (say sumSal). In this getSumSal() method you

  1. use ELContext and ValueExpression ExpressionFactory to resolve the reference #{line} (you can cast oracle.jbo.domain.Row
  2. call the row.get ("attribute_name") to access the value of the field
  3 compute and return the value to display in the table

  Note that using a transitional attribute may be easier to achieve and easier to reuse in other uses of the VO. However, you will have options

• The legacy of values on the expansion of the tables

  Hello

  I have a drop-down list (unlimited package) including rawValue sets/triggers the value field & access to another field of drop-down list (BillStudent) which resides in an expandable row in a table. However, I want all cases/additional lines that are added to the table to inheret the value defined by (unlimited package) when you add more lines.

  What I have right now is this where "Admin_Use = name of the form, table 3 = Table name, Row1 = line Explandable and BillStudent = combo box residing in the line.

  Under the 'exit' event

  If (FlatRate.rawValue == 2) {}

  Admin_Use.table3.Row1.BillStudent.RawValue = 3;

  Admin_Use.table3.Row1.BillStudent.access = 'protected ';

  }

  else {Admin_Use.Table3.Row1.BillStudent.rawValue = null;

  Admin_Use.table3.Row1.BillStudent.access = "open";

  }

  The code works as I want it, for the first existing line. However, when I add another line, the new line does not have the same value as the previous. I want to repeat this value for all new instances added to the table.

  Thank you very much!!!

  J

  Hello

  I think you can get what you want by moving your code from the output event of unlimited plan for the event of Row1 calculate, so it will look something like;

  If (FlatRate.rawValue == '2')

  {

  BillStudent.access = 'protected ';

  BillStudent.rawValue = '3 '.

  }

  on the other

  {

  BillStudent.access = "open";

  BillStudent.rawValue = null;

  }

  Note: The reference to FlatRate maybe wrong according to the structure of your form.

  Good luck

• Going crazy on the values of stale table f *.

  Some seriouse need help now.

  My goal is to build a table whenever a real touch.

  1. create a table based on the values programitlitly beeing past in the table

  2. This should each time when a Boolean value is true.

  3. the table building function should wait 6 s before storing in the table when the value is true

  My problem is that when I press True, and I start changing the starting value (say 0) desired value I want that it either (say 5) before six seconds pass, the value passed to the table after 6 seconds is the starting value of 0 not the value of dessired 5. This value appears the next time that I push the real button.

  It drives me crazy

  And the desired value must come within a structure of sequence because of the structure of the main VI (this is just an excerpt of this cose)

  HELP Please!

  Probably, this should solve your problem.
