  • How do find no data in the table

    Hi all

    I have 250 table in my diagram and when I query like this

    Select * from object where type_objet = 'TABLE' and owner = 'MATTELLI.
    order by object_name CSA


    Some tables have no data in it. How to find the tables that not have data or records

    Thanks and greetings
    Srikkanth.M

    Hi Srikkanth,

    First of all, if you are only interested in object TABLE type, so you should better use dba_tables instead of dba_objects.
    Then, assuming that your statistics are up to date, it would look like:

    SELECT *
      FROM all_tables
     WHERE owner = 'MATTELLI'
      AND num_rows > 0
     ORDER BY table_name ASC
    

    Otherwise, you can go with a subquery and a 'select count.

  • 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

  • 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.

    A.
