  I would like to know the difference between same tr_ids create_time, which should give out in hours except Sunday.
  
  For example:
  
  TR_ID: S12344
  1002_Create_time: July 1, 12 PM 10.01.06.657000 (i.e. Sunday)
  1003_Create_time: 12.01.04.188000 AM 6 July 12
  
  1002 create time is 22:00 Sunday.
  
  If the query must exclude only the hours of Sunday which is 10 p.m. to Monday 00 h which is 2 Hrs.
  
  I tried the sub query after doing a search on this forum but I am not getting the desired output.
  

  SELECT count(*) FROM (SELECT ROWNUM RNUM,tr_id,create_time CT_1002 FROM test c WHERE c.tr_id='S12344' and 
  ROWNUM <= (select (cast(a.create_time as date)-cast((select create_time from test b where a.tr_id=b.tr_id and code=1002) as date)) 
  from test a where a.code=1003 and a.tr_id=c.tr_id) + 1) d 
  WHERE to_char(cast((select create_time from test e where e.tr_id=d.tr_id and code=1002) as date) + RNUM - 1, 'DY') NOT IN('SUN');

  Need help to get the desired o/p

  Hello

  If I unederstand the problem correctly, that's what you want:

  WITH       got_extrema     AS
  (
       SELECT       tr_id
       ,       CAST (MIN (create_time) AS DATE)     AS start_date
       ,       CAST (MAX (create_time) AS DATE)     AS end_date
       FROM       test
       GROUP BY  tr_id
  )
  SELECT       tr_id
  ,       start_date, end_date          -- If wanted
  ,       24 * ( ( ( TRUNC (end_date,   'IW')          -- Count -1 day for every full week
                      - TRUNC (start_date, 'IW')
               )
             / -7
                )
              + LEAST ( end_date               -- If end_date is a Sunday
                          , TRUNC (end_date, 'IW') + 6     -- consider it 00:00:00 on Sunday
                   )
              - CASE
                        WHEN  start_date >= TRUNC (start_date, 'IW') + 6     -- If start_date is a Sunday
                 THEN  TRUNC (start_date, 'IW') + 6               -- consider it 00:00:00 Sunday
                 ELSE  start_date
                    END
              )     AS total_hours
  FROM      got_extrema
  ;
  

  I guess that you don't need to worry about fractions of a second. As you did in the code you have posted, I am to convert the TIMESTAMP to date values, because of DATE arithmetic and functions are so much better than what is available for timestamps.

  Basically, it's just to find the number of days between start_date and end_date and multiplying by 24, with these twists:
  (a) 1 day is deducted for each week between start_date and end_date
  (b) if End_date is a Sunday, none of the end_date himself hours are counted
  (c) If start_date is a Sunday, then all the start_date himself hours are counted. Why these hours should be counted? Because 1 day is already being deducted for the week which includes start_date, which contains only this Sunday.

  TRUNC (dt, 'IW') is the beginning of the ISO week containing dt; in other words, 00:00:00 the or before the dt last Monday. This is not the NLS parameters.

  Of course, I can't test without some sample data and the exact results you want from these data. You may need a little something more If start_date and end_date are both on the same Sunday.
  Whenever you have a problem, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) of all of the tables involved.
  Also post the results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.
  Always tell what version of Oracle you are using.

• How to find the difference between two dates in the presentation layer

  Hi gurus,
  
  Hello to everyone. Today, I came with the new requirement.
  
  
  I need to know the difference between a date and the current date in the formula column application presentation layer.by.
  
  
  
  Thank you and best regards,
  Prates

  Hi Navin,

  TIMESTAMPDIFF function first determines the timestamp component that corresponds to the specified interval setting. For example, SQL_TSI_DAY corresponds to the day component and SQL_TSI_MONTH corresponds to the component "month".

  If you want to display the difference between two dates in days using SQL_TSI_DAY, unlike butterflies SQL_TSI_MONTH and so on...

  hope you understand...

  Award points and to close the debate, if your question is answered.

  See you soon,.

• How to find the number of data items in a file written with the ArryToFile function?

  I wrote a table of number in 2 groups of columns in a file using LabWindows/CVI ArrayToFile... Now, if I want to read the file with the FileToArray function so how do I know the number of items in the file. during the time of writing, I know how many elements array to write. But assume that I want the file to be read at a later time, then how to find the number of items in the file, so that I can read the exact number and present it. Thank you all

  Hello

  I start with the second question:

  bytes_read = ReadLine (file_handle, line_buffer, maximum_bytes);

  the second argument is the buffer to store the characters read, so it's an array of characters; It must be large enough to hold maximum_bytes the value NULL, if char [maximum_butes + 1]

  So, obviously the number of lines in your text tiles can be determined in a loop:

  Open the file

  lines = 0;

  While (ReadLine () > 0)

  {

  lines ++;

  }

  Close the file

• To find the first Summit for data channel

  Hey guys,.

  I need a little help. I wrote a script to process some data. Basically, what the script does is calculate the linear accelerations peak, peak of the angular speeds, HIC values and IF. But there is a problem with my script that I need help. In my script, I use the ChnPeakFind command to find the pics in my chains. This command works fine to find the peak value, but what I want to do is find the FIRST Summit in the data, without worrying whether or not it is a maximum. I always encountered data that varies in which my first pic (impact analysis) may or may not be the highest point in the channel. As you can see in the Graphs.png that I have attached, the ChnPeakFind command found the 2nd Summit (red circle #2) in my chain of angular velocity (ARS resulting). But what I report is the first peak value (red circle #1). I've also attached a screenshot of the section in my code where I calculate the angular velocity. The 'i' in the calculation is just the channel group number. In this case, it is 1. Anyone know how to change the code or have another suggestion how to find the first Summit in a channel without having to stop and go to the tab analysis to manually find the pic?

  Thank you!

• How to find the velocity of an incremental encoder

  I use the RE22I encoder which can give up to 8192 pulses per revolution, I have A, B, Z reports that I use an fpga as a controller Please help me.

  How to find the speed of the encoder using these signals I'm going to have a clock in the fpga sysytem will help.

  Start by looking at the information on Wikipedia on the rotary encoders and a book on encoders OR white.  These articles will give you a basic understanding of the encoder and the signals it produces.

  With proper decoding, you can get the direction and momentum of each of the points on your encoder 8192.  If the tree can reverse (same vibration on one point unique all-in-mnearly stationary), full decoding must be used.  If data are only of interest while the tree turns in a direction and speed will not close to zero, a simple decoding can be used.  Decoding of a quadrature encoder is a good way to learn to use a state machine.  Signals A and B can exist in only four possible combinations, but the possible transitions to do interesting things.

  Define DECODING is a purely logical exercise and it is a simple coding in LabVIEW, such as a state machine.  There are examples, Desing Patterns, or project templates (depending on your version of LV) that come with LV to help you get started.

  By using the channels A and B you can update your calculation of velocity 8192 times per turn.  With the help of Z you get only an update by the revolution. You use depends on your application.  The pulse of Z is also useful to define a reference position for the measurement of phase angle.

• How to find the position of the VI icon currently run on the block diagram of the appellant

  Dear forum,

  I am currently trying to use a LabVIEV VI as a simple sequencer: several (very slow) actions must run one after the other. Each action is represented by a Sub - VI, some actions are executed several times. My task is to view the Subvi somehow executing.

  My first intention (just manipulate the icon of the VI running with 'Icon.Get VI as Image data' / 'Icon.Set VI of Image data' invoke nodes) has failed, because it changes all instances of the VI icon. If you use the same VI several times, all these VI icons are changed (see here: http://forums.ni.com/t5/LabVIEW/How-to-change-animate-icon-of-currently-running-VI/m-p/3120754/highl... )

  My current approach is to use an image of the block diagram (with "VI: block diagram: get resized Image ' call method) in a picture of the front panel control and working within this control. But for this I need to know the position of the icon of the VI running. I know that I can assess the limits and Position via the properties GObj, but how to find the VI running (note that a VI can be installed several times on the block diagram, so the name of the VI is not unique)? IMHO the easiest way might be if a VI might find its icon on the block of the appellant diagram itself when it is run...

  It is clear that this position is not yet the position on the photo, but this conversion is a small piece of work...

  Kind regards

• OBIEE 11 g: how to find the 2nd Friday of the month

  Hello

  How to find the 2nd Friday of the month using the current date in obiee 11g.

  Thanks in advance.

  Kind regards

  MIT.

  Hey MIT,

  You can try with something like this:

  TIMESTAMPADD (SQL_TSI_DAY, TIMESTAMPADD (7 + 6-DAYOFWEEK (TIMESTAMPADD (SQL_TSI_DAY, 1-DAYOFMONTH (CURRENT_DATE), CURRENT_DATE))), (SQL_TSI_DAY, 1-DAYOFMONTH (CURRENT_DATE), CURRENT_DATE))

  It can still be improved to probably avoid transformations 1-2, but at least he does.

  You will need to check what return DAYOFWEEK in your environment for Friday (in mine Friday = 6) as if she does not return to Friday 6, you will need to adjust the formula.

  The idea is to find what day is the first day of the month, since then visit the first Friday (or just stay there if the first day is a Friday). This is done by the DAYOFWEEK 6 (first day of the month).

  And now, you just add more 7 days, so that's why there is a 7 + 6 - DAYOFWEEK (first day of the month) to make it easier to read and understand (instead of 13-...).

• How to find the size of the virtual server?

  Hello

  We intend to pass our applications 4 virtual servers has 2 physical servers. In this process, we need to identify the size of the current virtual servers to use as a starting point to configure or add the size in physical server. can anyone provide information on whats stats to be noticed and how to find the size of the current virtual servers?

  Thank you

  Hi Sekhar, there.

  in general, it is a fairly complex task if you want to size the new platform correctly, i.e. not to oversize it and have very low use below, i.e. spend too much on equipment.

  In fact, it's the first thing to consider the level of use of the new platform. Most likely your organization (HW and infrastructure) has targets to a minimum. optimal and maximum usage levels.

  In the case where you do not have this as a starting point, and then you continue with load average and the current peak (CPU, RAM, NW). To these basic lines, you can use the statistics of WLS Admin Console, where the use of CPU and memory statistics are presented since the server was last started. For more detailed statistics, you can use WLDF to capture measures key at regular intervals, and then base your analysis of these data.

  Finally and above all, the size of FS, but I've seen some comments above related to the size of the FS.

  HTH,

  A.
