• Filter for table data, the range of data obtained and defined 2D

  I produce data of an ultrasonic sensor at 1 K Hz, and there is a lot of data (data points range of 0 to 10). However, in some cases when I know that the data should be about 7 (for example) I get outliers (about 9 and 10). Is it possible to define a filter for data in the defined range.

  I averaged the data to get an average value, and outliers are distorting. In the worst case, my outliers are 30 to 40% of the data generated. I created a filter to sort the data and, taken from the lowest value. I stop the loop when data reaches a value greater then 9. But this seems to take a long time (because the loop checks for each data point and there are 1000s of them).

  Is there a better way to filter data and define a predefined table range to collect?

  I enclose my filter.vi... and a set of samples of my previous data. The ranges of data of 10-8 and would like to have the range 7.5 to 8.5 to consider. The sensor records tension here and the problem can be solved by installing a different type of sensor, but if a filter in LabView can due it, the sensor that we use now is absolute.

  I am in kind of emergency, my design in unfinished because of this problem, if someone can find some time to share some suggestions, I will be grateful.

  Thanks in advance.

  See attachment.  I have incorporated the data you've posted in the vi.  It doesn't seem like any data were less than 8.7 or so, so I modified the scope so it would be a few points on average.  Some games were completely out of reach while the average came back like NaN (not a number) due to a division by zero.

• How to define the range of data to a strict typdef through the control reference

  Hello world

  I'm trying to define the range of data to a strict typdef through the reference of the order, when I do, I get an 'error of property node.

  Try to set the original control (type-def) and not its instances... to open the reference of the original type-def command, use 'Open VI reference'.

• How to filter for a range of dates calendar events in OS10

  In earlier versions of BlackBerry, I used blackberry.find.FilterExpression to filter the events calendar for a specific range of dates.

  However for BlackBerry OS10 I scoured the web to find a way to do it. I found:http://developer.blackberry.com/html5/apis/blackberry.pim.calendar.calendarfindoptions.html

  I also googled a lot of other sites, but I am unable to understand how to use CalendarFindOptions to refine the calendar of events of a specific timetable. For example, the current week or the next 7 days.

  I found this code example...
  Function listEvents (limit) {}
  Calendar var = blackberry.pim.calendar;
    var CalendarFindOptions = calendar. CalendarFindOptions;
    var findOptions = {}
  'Sort': [{}
  "fieldName": CalendarFindOptions.SORT_FIELD_SUMMARY.
  'desc': false
  }],
  'detail': CalendarFindOptions.DETAIL_AGENDA,
  'limit': limit
  };

  But unable to find examples how adequately limited by date?
  I'm guessing that something like this:
  'Start': new Date (' January 1, 2013, 13:00 "): CalendarFindOptions.SORT_FIELD_START.
  'end': new Date (' January 1, 2013, 16:00 "): CalendarFindOptions.SORT_FIELD_STOP.

  But it is an assumption and does not work I can find no example of how do

  Any help would be appreciated

  See the example for pimcalendar on Github:

  Hi gurus

  I'm stuck with a scenario and your employees need help to solve this problem.

  I have the following table:

  Insertion and table creation

  Union of all the

  Select 300,3, to_date ('2013-03-01 ',' YYYY-MM-DD '), double null

  );

  Query on table

  Select * ident;

  ident_dtl_pk number (5),

  date of effective_date,

  date of termination_date

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

  insert into ident_dtl

  (

  Select 1-ident_pk, 10 ident_dtl_pk, to_date('2013-01-01','YYYY-MM-DD') effective_date, to_date('2013-01-31','YYYY-MM-DD') termination_date of double - to agreement_id = 100

  Result of the will

  Agreement_Id Ident_pk

  200                                        2

  300                                        3

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

  There is a single entry in ident against agreement_id and Ident_pk and if you can see that ident_pk is also present in the child table. My requirement is that at least 1 effective_date and child termination_date table must be match/equal to the parent table that is ident cov_effective_date and cov_termination_date against the same column of Ident_pk.

  for example:

  See the data in Ident_pk = 1, a = cov_effective_date 13/01/01 and its cov_termination_date = 13/01/31 and in the details table against column Ident_pk = 1, you can find that at lease 1 combinaisondes date match against Ident_pk = 1

  If you see Ident_pk = 2, then you can't find all the effective_date and termination_date against its corresponding cov_effective_date and termination_date Ident_pk...

  Same as 3

  -----------

  Summary is that there are date range in the ident against agreement_id and Ident_pk table and at least a range of dates even should be exist in detail table is ident_dtl against Ident_pk and if not then show that agreement_id and Ident_pk .

  I made this task using PL/SQL, but I think that there is a way to do the same task in SQL. Guide and if you have any questions then please let me know. Thank you

  Hello

  To be considered as a football game, the same line in ident_dtl must have effective_date and termination_date correspondence?

  If so, a solution is:

  SELECT i.agreement_id

  i.ident_pk

  Ident I have

  LEFT OUTER JOIN ident_dtl d.ident_pk d = i.ident_pk

  AND d.effective_date = i.cov_effective_date

  AND d.termination_date = i.cov_termination_date

  WHERE d.ident_pk IS NULL

  ;

  Another pure SQL approach to such problems is to use an EXISTS subquery.

• Extend a range of dates

  I have the following query, which works without problem. This will expand the range of dates, proof of identity, in a list of dates for me:

                       - date_1
                       + 1);

  Thank you.

  Hello

  Here's one way:

  WITH   cntr          AS
  (
       SELECT     LEVEL - 1     AS n
       FROM     (
                SELECT  MAX (date_2 - date_1)     AS max_dif
                FROM    table_x
            )
       CONNECT BY     LEVEL <= 1 + max_dif
  )
  SELECT       x.j_id
  ,       x.date_1 + c.n
  FROM       table_x  x
  JOIN       cntr        c  ON  c.n <= x.date_2 - x.date_1
  ORDER BY  x.j_id
  ,            c.n
  ;
  

  If you do any filtering, it may be more effective to do this first. Start the WITH clause with a subquery that performs filtering, then use this result placed instead of your full table in the view online within the cntr as well as in the main query.
  For example:

  CREATE TABLE  table_x         AS
           SELECT 123 j_id, TO_DATE('01/01/2012', 'DD/MM/YYYY') date_1, TO_DATE('31/01/2012', 'DD/MM/YYYY') date_2
              FROM   DUAL
              UNION
              SELECT 456 j_id, TO_DATE('01/02/2012', 'DD/MM/YYYY') date_1, TO_DATE('29/02/2012', 'DD/MM/YYYY') date_2
              FROM   DUAL
  UNION         SELECT 999,          TO_DATE ('01/01/2013', 'DD/MM/YYYY'),     TO_DATE ('31/12/2013', 'DD/MM/YYYY')     FROM dual
  ;
  
  WITH     filtered_data     AS
  (
       SELECT     *
       FROM     table_x
       WHERE     date_1     < TO_DATE ('01/07/2012', 'DD/MM/YYYY')
  )
  ,        cntr          AS
  (
       SELECT     LEVEL - 1     AS n
       FROM     (
                SELECT  MAX (date_2 - date_1)     AS max_dif
                FROM    filtered_data
            )
       CONNECT BY     LEVEL <= 1 + max_dif
  )
  SELECT       f.j_id
  ,       f.date_1 + c.n
  FROM       filtered_data  f
  JOIN       cntr              c  ON   c.n  <= f.date_2 - f.date_1
  ORDER BY  f.j_id
  ,            c.n

  is it possible to achieve through sql query in oracle
  Thanks in advance for all friends to help him

  Hello

  Something like this (assuming that the dates are originally VARCHAR2s):

  SQL> var dt_start varchar2(10)
  SQL> var dt_end varchar2(10)
  SQL> exec :dt_start := '12-01-2011'
  
  PL/SQL procedure successfully completed
  
  SQL> exec :dt_end := '14-04-2011'

  RESULT
  -----------
  31/01/2011
  28/02/2011
  31/03/2011
   
  

  If the dates are already of the date data type, simply remove the to_date function.

• SQL to generate the intervals from date of 6 months each, between two date ranges

  Hi all
  
  I looked in the forums, if someone uses CREATE_CHUNKS_BY_SQL for dates, but no luck.
  I want to update a table using pieces of dates.
  I need to generate date ranges to divide them by pieces.
  
  I have a table where I know that max (sales_date) and min (sales_date).
  Lets say max (sales_date): min (sales_date) 01/01/2008: 31/10/2010
  
  I want to break in intervals of 6 months (180 days) as below:

  chunk_id     start_date     end_date
  --------     ----------     --------
    1          01/01/2008     06/30/2008
    2          01/07/2008     12/31/2008
    3          01/01/2009     06/30/2009
    4          01/07/2009     12/31/2009
    5          01/01/2010     06/30/2010
    6          01/07/2010     10/31/2010

  He didn't exactly finish end of the month. Basically, I need these beaches of dates at apart 180 days.
  
  I appreciate if someone can throw some ideas on this.
  
  Thank you
  Raj.

  Hi, Raj,

  Sorry, it is unclear what you are asking.

  To generate a list of dates starting with min_sales_date and including all the 180 days after that up to (but not beyond) max_sales_date:

  WITH     got_params     AS
  (
       SELECT     DATE '2008-01-01'     AS min_sales_date
       ,     DATE '2010-10-31'     AS max_sales_date
       FROM     dual
  )
  SELECT     min_sales_date + (180 * (LEVEL - 1))     AS grp_start_date
  FROM     got_params
  CONNECT BY     LEVEL <= CEIL ( ( (max_sales_date - min_sales_date)
                                  + 1
                         )
                       / 180
                       )
  ;
  

  Output:

  GRP_START_D
  -----------
  01-Jan-2008
  29-Jun-2008
  26-Dec-2008
  24-Jun-2009
  21-Dec-2009
  19-Jun-2010
  

  December 16, 2010 is 180 days after June 19, 2010, but it is not displayed, because is after max_sales_date, which is 31 October 2010.

  I hope this helps you.

• New in MapPoint. Can help you with the selection of a range of data?

  Hello

  I just open MapPoint 2013 as import data, select a radius from a given location and export data.  That's all I need of MapPoint to manage but can't seem to find a small tutorial on how to on this subject.

  I tried flying by the seat of my pants, so to speak and have selected a range of 70 minutes, but the output file shows only 96 files when I know that many more within a radius of driving I've selected.  Bugs appear to be associated with zip codes.  For example, in the Excel file there are no addresses (records) but only zip codes and a list indicating the number of organizations within each zip.  I want real organizations in a range of one hour.

  PROFILE of column

  I havets is of type VARCHAR2. I know that again I can partition as Oracle convert internally to varchar2 in number when the data is inserted. But the INTERVAL is not possible.  However, so could you please suggest how RANGE partition on PROFILE?

  It's the NUMBER with decimals. Could you guide me please?

• Catch the range of Date values

  Hi, guys.
  
  I need to check the date range that my product was available. You can use as a basis the values in the table below, but this structure can be modified to add all the things that could support the solution:
  
  ID_PRDCT DT_STRT DT_END
  1 20/01/25 12/01/12
  1 01/23/12-27/01/12
  1 26/01/30 12/01/12
  1 28/01/12-21/04/12
  1 20/04/12-25/05/12
  1 24/05/12-28/05/12
  1 26/05/12 05/29/12
  1 01/07/12-03/08/12
  1 01/08/12-16/08/12
  1 18/08/12-30/08/12
  1 01/12/12-31/12/12
  
  In this case, the result of my date range should be:
  
  1 20/01/12-29/05/12
  1 01/07/12-16/08/12
  1 18/08/12-30/08/12
  1 01/12/12-31/12/12

  Hello

  An the Heres how:

  WITH     got_new_grp          AS
  (
       SELECT     id_prdct, dt_strt, dt_end
       ,     CASE
                WHEN  dt_strt <= MAX (dt_end)
                          OVER ( PARTITION BY  id_prdct
                                 ORDER BY      dt_strt
                           ROWS BETWEEN  UNBOUNDED PRECEDING
                                  AND      1          PRECEDING
                         )
                THEN  0
                ELSE  1
            END     AS new_grp
       FROM    t
  )
  ,     got_grp          AS
  (
       SELECT     id_prdct, dt_strt, dt_end
       ,     SUM (new_grp) OVER ( PARTITION BY  id_prdct
                                     ORDER BY          dt_strt
                         )         AS grp
       FROM    got_new_grp
  )
  SELECT       id_prdct
  ,       MIN (dt_strt)     AS grp_dt_strt
  ,       MAX (dt_end)     AS grp_dt_end
  FROM       got_grp
  GROUP BY  id_prdct
  ,            grp
  ORDER BY  id_prdct
  ,            grp
  ;
  

  This assumes dt_strt<= dt_end="" on="" every="">
  If you would care to post CREATE TABLE and INSERT statements for your sample data, then I could test it.

  You cannot use LAG or LEAD to see where each new group starts, because the order of the dt_strt is not the same as the order of the dt_end. In other words, if you ORDER BY dt_strt, two adjacent lines could be in the same group regardless of their values, because a previous line can have a dt_end, and as a result this line would be overlapp both of them. Similarly, if you ORDER BY dt_end, no matter what two adjacent lines contain, whether they are in the same group if som rank later has a sufficient dt_strt in advance.

• How to get the number of days in a month of belonging to a range of dates

  Hi, I'm going crazy around a problem, I have 2 dates and one month I wanto to retrieve the number of days belonging to the months that fall within the range.
  
  for example:
  
  month of January 2011. begin_date = January 11, 2011, May 30, 2011 end_date result is 21
  month of January 2011. begin_date = December 11, 2010, result of end_date, January 10, 2011 10
  month January 2011 .begin_date = 2 February 2011, end_date may 25, 2011 result 0
  month of January 2011. begin_date = January 3, 2011, January 5, 2011 result DATE END 3
  
  and so on...
  
  I appreciate any suggestion
  Thank you
  
  
  Andrea

  Something like that... ?

  SQL> with t as
    2  (select  to_date('11/01/11','dd/mm/yy') from_dt,
    3           to_date('30/05/11','dd/mm/yy') to_dt,
    4           'Jan-11' mnth from dual)
    5  select least(last_day(to_date(mnth,'Mon-yy')),to_dt) -
    6         greatest(to_date(mnth,'Mon-yy'),from_dt) cnt
    7  from t  ;
  
         CNT
  ----------
          20
  

  If 0 is also expected...
