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

    I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
    If you are young work to Learn, not to earn.
    Solved!
    Go to Solution.

    What about:
    OpenFile ( your file );
    cnt = 0;
    while ((br = ReadLine ( ... )) != -2) {
    if (br == -1) {
    // I/O error: handle it!
    break;
    cnt++;
    CloseFile ( ... );
    There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
    After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
    Proud to use LW/CVI from 3.1 on.

  • How to find the original lengh of a VARCHAR2 field

    Hi all...
    How to find the original lengh of a VARCHAR2 field. If i use, length function, it is
    giving the length of the feild, not the orginal length of field value.
    How to find the actual length of the field.
    Thanks in advance
    pal

    > How to find the original lengh of a VARCHAR2 field.
    Why?
    And where? A varchar2 in SQL or a varchar2 in PL/SQL? Varchar2 arguments have no explicit size in parameter signature for a procedure or a function.

  • How to find the number of occurance of a string in text field of Infopath form?

    Hi All,
    In Infopath text field, How to find the number of occurrence of a particular string in that field?
    Thanks in advance!

    You can check to see if it contains a string once by using the contains function, but there isn't a very clean way to do what you want. If you wanted to guess at the maximum number of occurrences, then you could:
    Box A has your initial. Set Box B to do a concat of string-before and string-after of Box A where it copies Box A minus the string we're looking for. Then we have Box C that does the same thing to Box B. Repeat as many times as you see necessary.
    Example:
    String: "1"
    Box A - "123451234512345"
    Box B - "23451234512345"
    Box C - "2345234512345"
    Box D - "234523452345"
    etc.
    We then have a field that has nested ifs looking backwards from Z -> A looking for a non-blank. Based on that, we return the number of occurrences. Again, this isn't clean, but it will work if you think there's a predefinable maximum.

  • How to find the number of records per months  in cube

    Hi,
      how to find the number of records per months for my all cubes?
      Can i use the ListCube transaction to find totl number f records per cube monthwise ?
    Jimmy

    Hi,
    Here is a program to generate no of records and list of ODS and Cubes in Active version.Schedule this program in background and create a cube to load this information and schedule to the data from the file generated by the program. Schedule this all per you requirement.
    1.Copy the code into your Z<programname> from Se38.
    2.change the FILENAME in CALL FUNCTION 'GUI_DOWNLOAD' in the program to the location from where you can pick the information to load data to cube(eg Application server).
    3.Save program.
    4.Schedule the program in background as required
    5.Create cube with infoobjects to hold no of records and Infoprovider name
    6.Load this cube based on event after the program job is done.
    Hence you can report on this cube to see no of records in  CUBE or ODS in your box.
    Please find the code below.

  • How to find the number of records in ods?

    how to find the number of records in ods?
    Pls suggest the solution apart going to the table of ods and seeing the number of records.
    Is there any program or function module to see the number of records in ods?
    For eg: SAP_INFOCUBE_DESIGNS is a program which gives the detail (number of records) of infocube.

    Hi,
    I was looking at this and found the following tables that may be of help.
    One of these tables will include a summary of the record count of all the tables in your system based on the last time each table had it's database statistics calculated:
    DBSTATTADA
    DBSTATTDB2
    DBSTATTDB4
    DBSTATTDB6
    DBSTATTINF
    DBSTATTMSS
    DBSTATTORA
    We run on an Oracle database so the table record counts can be taken from DBSTATTORA. Type in AZ in table selection field in SE16 to restrict the output to ODS (or DSO) tables only.
    The record count is at the time indicated in the timestamp field. Obviously this is not real time but should not be too out of date - if it is you may be having performance issues and should get your DBA / Basis to run a full refresh of DB stats.
    Hope this helps, alhtough not real time the table should give you a decent indication of the size of all your ODS objects (or any other table for that matter!)

  • HOW TO FIND THE REQUIRED DELIVERY DATE IN VA02

    hi
    HOW TO FIND THE REQUIRED DELIVERY DATE IN VA02.
    i want to display this field in my report. what is the fieldname and in which table it is ?

    Hi Jyothsna,
    There are 2 dates when you say Requested Delivery Date
    1.  Header level in VBAK-VDATU is the field
    2.  At item level it is in the schedule line. VBEP-EDATU.
    The relationship between item (VBAP ) and schedule line ( VBEP )is 1 to many. But there will be mutiple schedule lines only if you are using the scheduling functionality. Also note to check for confirmed quantity (VBEP-BMENG) to be greater than 0 and use that schedule lines EDATU date as Requested delivery date.
