How to read the size of the array, eliminating empty values

I have an array of size 2 X 10. In the first column, the elements are 10 and in the second column, the elements are only 6. If I use the size of the array and the size of the second column of the index, the value given is 10 which is supposed to be 6. I noticed that it creates null or empty values in the column for the other four. How can I eliminate empty values, and only get the real sze of the column?

The column in the index and use search 1 D table for an empty string.  The result should be the number of non-empty strings.  If the result is - 1, use the actual size of table.

    If you have VI Analyzer installed, you can load the configuration file and look at the section select the Tests. There is a test for the maximum size of front under front-> User Interface. The default value is the resolution of the current monitor of the PC (including multiple monitors). You can change to the desired option.

    Raj,

    Here is the code

    --This is you will create
    create or replace type TYP_PHONES as table of Varchar2(15) ;
    /
    --- This will be your procedure
    create or replace
    procedure give_me_an_array1( p_array in TYP_PHONES )
    as
    begin
    -- Do whatever you want to with the data you get
    for i in 1 .. p_array.count
    loop
    dbms_output.put_line( p_array(i) );
    end loop;
    end;
    /
    

    Tell your guy java to define this table as below

    String[] intArray= {"john","miller","scott"};
    ArrayDescriptor descriptor =ArrayDescriptor.createDescriptor( "TYP_PHONES", conn );
    ARRAY array_to_pass = new ARRAY( descriptor, conn, intArray );

  • How to read the status of User1 DIP-switch with a cRIO FPGA chassis?

    How to read the State of the DIP switches on a FPGA cRio chassis?

    I work with a cRIO 9022... My idea is to put the system in "service" mode with USER1 switch to IT and communicate with the FPGA via the FPGA - GUI (VI) on the host computer instead via the RT module that is used in normal conditions.

    Any ideas? Unfortunately, I don't have an unused channel on the left... .and (as I know) cannot use the interface RS232 of FPGA.

    Many thanks in advance,

    Luke

    Hi, this is the correct information. You cannot read the FPGA of DIP-switch status. The only thing you could do is to use the function of Reading Switch.vi located under the range of functions-> real-> utilities RT time

    It's how you probably know side host RT and not the FPGA.

  • How to read the two columns of data from the Port series

    Hello

    I'm reading two columns of data from the serial port.

    Example:

    52439 52430

    52440 52437

    52209 52214

    51065 51070

    52206 52390

    I use the serial of Visa service and I can read the first column of data from the serial port, but I can't understand how to read the second column.

    I want to both sets of chart data.

    I enclose my VI.

    Thank you for your help.

    The analysis of string function takes a "Format string" on top (with the right button of the function and choose Help, which explains all the entries).  In particular, you can say 'Give me two numbers separated by a tab' and the output will be two numbers (whole or floating, depending on the chosen format).  In particular, %d\t%d specifies a decimal integer, , whole decimal.

    pop up on the wire table refernece and establishes 'control '. Add this control to the icon of the sub - VI decision-making and then wire ref of the appellant to this Terminal VI so the calling VI move the ref to the Subvi.

  • Don't know how to read the results of netstat EI s list? If I received 860592506 bytes sent from 43421482 how to convert MB? And does this mean byte received?

    Don't know how to read the results of netstat EI s list? If I received 860592506 bytes sent from 43421482 how to convert MB? And does this mean byte received?

    Hello

    This shows the total number of bytes transmitted and received via the Ethernet card. This is the total of the amount of use up to this day.

    This includes all the Web sites you have visited and emails you sent, etc..

    You can calculate using one of the following methods:

    Method 1:

    860592506 / 1048576 = 820,72 MB

    Method 2:

    Multiply 860592506 with 9.53674316 * 10 ^-7 that will give us the result in mega bytes.

    860592506 bytes = 820 MB 9MB not, accept my apology for the miscalculation.
    Similarly 43421482 acroos = 40MB
