Loading MAT data files

Hi,
I am using Mathscript window to load MATLAB mat-file.  After the confirmation of when the file is loaded, I find the variable src1 to be empty.  It should contain a field of data.  I have attached the dta file for your evaluation.  Please advise what I am doing wrong.
Regards,
Duc

Hello Duc,
Unfortunately, your .mat file contains a structure, which LabVIEW MathScript does not currently support.  We are aware of this limitation and hope to offer support in a future version.  As a workaround, you can save your data as separate variables instead of a cluster (e.g. src1_RangeMin, src1_RangeMax, etc.)

  • How to load unicode data files with fixed records lengths?

    Hi!
    To load unicode data files with fixed records lengths (in terms of charachters and not of bytes!) using SQL*Loader manually, I found two ways:
    Alternative 1: one record per row
    SQL*Loader control file example (without POSITION, since POSITION always refers to bytes!)<br>
    LOAD DATA
    CHARACTERSET UTF8
    LENGTH SEMANTICS CHAR
    INFILE unicode.dat
    INTO TABLE STG_UNICODE
    TRUNCATE
    A CHAR(2) ,
    B CHAR(6) ,
    C CHAR(2) ,
    D CHAR(1) ,
    E CHAR(4)
    ) Datafile:
    001111112234444
    01NormalDExZWEI
    02ÄÜÖßêÊûÛxöööö
    03ÄÜÖßêÊûÛxöööö
    04üüüüüüÖÄxµôÔµ Alternative2: variable length records
    LOAD DATA
    CHARACTERSET UTF8
    LENGTH SEMANTICS CHAR
    INFILE unicode_var.dat "VAR 4"
    INTO TABLE STG_UNICODE

    ) Datafile:
    001501NormalDExZWEI002702ÄÜÖßêÊûÛxöööö002604üuüüüüÖÄxµôÔµ Problems
    Implementing these two alternatives in OWB, I encounter the following problems:
    * How to specify LENGTH SEMANTICS CHAR?
    * How to suppress the POSITION definition?
    * How to define a flat file with variable length and how to specify the number of bytes containing the length definition?
    Or is there another way that can be implemented using OWB?
    Any help is appreciated!
    Thanks,
    Carsten.

    Hi Carsten
    If you need to support the LENGTH SEMANTICS CHAR clause in an external table then one option is to use the unbound external table and capture the access parameters manually. To create an unbound external table you can skip the selection of a base file in the external table wizard. Then when the external table is edited you will get an Access Parameters tab where you can define the parameters. In 11gR2 the File to Oracle external table can also add this clause via an option.
    Cheers

  • SQL*Loader Sequential Data File Record Processing?

    If I use the conventional path will SQL*Loader process a data file sequentially from top to bottom?  I have a file comprised of header and detail records with no value found in the detail records that can be used to relate to the header records.  The only option is to derive a header value via a sequence (nextval) and then populate the detail records with the same value pulled from the same sequence (currval).  But for this to work SQL*Loader must process the file in the exact same sequence that the data has been written to the data file.  I've read through the 11g Oracle® Database Utilities SQL*Loader sections looking for proof that this is what will happen but haven't found this information and I don't want to assume that SQL*Loader will always process the data file records sequentially.
    Thank you

    Oracle Support responded with the following statement.
    "Yes, SQL*LOADER process data file from top to bottom.

    Hi Cesar,
    I don't know if you have found a solution, but attached is a DLL built in VC that will read the text out of a file into a TestStand variable. The attached sequence file \SequenceFile1.seq contains a step type that is set to call the DLL responsible for reading the file. It reads the file specified under Step.FilePath and stores the data in Step.ReadData. Please let me know if this works for you. I have attached the source as well.

    Hello Priya
    If u r loading thru flat file
    1. Check the correct path in infopackage
    2. Check if it is opened,if it is then close it and run package again
    If loading thru R/3
    1. Check DS is not opened in change mode
    2. Check if RSA3 is able to extract data...if it is then check in RSA7 and chk IDOC status...
    3. Are you running init..then make sure no document is posted in R/3 side...
    Thanks

  • SQL Loader - CSV Data file with carraige returns and line fields

    Hi,
    I have a CSV data file with occasional carraige returns and line feeds in between, which throws my SQL loader script off. Sql loader, takes the characters following the carraige return as a new record and gives me error. Is there a way I could handle carraige returns and linefeeds in SQL Loader.
    Please help. Thank you for your time.
    This is my Sql Loader script.
    load data
    infile 'D:\Documents and Settings\user1\My Documents\infile.csv' "str '\r\n'"
    append
    into table MYSCHEMA.TABLE1
    fields terminated by ','
    OPTIONALLY ENCLOSED BY '"'
    trailing nullcols
    ( NAME CHAR(4000),
    field2 FILLER,
    field3 FILLER,
    TEST DEPT CHAR(4000)
    )

    You can "regexp_replace" the columns for special characters

  • SQL Loader: Multiple data files to Multiple Tables

    How do you create one control file that refrences multiple data file and each file loads data in a different table.
    Eg.
    DataFile1 --> Table 1
    DataFile2 --> Table 2
    Contents and Structure of both data files are different. Data file is comma seperated.
    Below example is for 1 data file to 1 table. Need to modify this or create a wrapper that would call multiple control files.
    OPTIONS (SKIP=1)
    LOAD DATA
    INFILE DataFile1
    BADFILE DataFile1_bad.txt'
    DISCARDFILE DataFile1_dsc.txt'
    REPLACE
    INTO TABLE Table1
    FIELDS TERMINATED BY ","
    TRAILING NULLCOLS
    Col1,
    Col2,
    Col3,
    create_dttm sysdate,
    MySeq "myseq.nextval"
    Welcome any other suggestions.

    I was thinking if there is a way to indicate what file goes with what table (structure) in one control file.
    Example ( This does not work but wondering if something similar is allowed..)
    OPTIONS (SKIP=1)
    LOAD DATA
    INFILE DataFile1
    BADFILE DataFile1_bad.txt'

    Hello Soma.
    How many records exist in your 700 MB CSV file? How many do you expect to process in 10 minutes? You may want to consider performing a set of simple unit tests with 1) 1 record, 2) 1,000 records, 3) 100 MB filesize, etc. to #1 validate that your shell script and control file syntax function as expected (including the writing of log files, etc.), and #2 gauge how long the processing will take for the full file.
    Hope this helps,
    Luke

  • SQL Loader reads Data file Sequentially or Randomly?

    Will SQL Loader loads the data read from file Sequentially or Randomly?
    I have the data file like the below
    one
    two
    three
    four
    and my control file is
    LOAD DATA
    INFILE *
    TRUNCATE
    INTO TABLE T TRAILING NULLCOLS
    x RECNUM,
    y POSITION (1:4000)
    so my table will be polulated like
    X Y
    1 one
    2 Two
    3 Three
    4 Four
    Will this happend sequentially even for the large data sets? say i have from one to one million datas in my data files.
    Please clarify.
    Thanks,
    Rajesh.

    SQL Loader may read the file sequentially, but you should not rely on the physical ordering of the rows in the table.
    It looks like that's what you were hinting at.

  • How to batch load multi data files  to several tables

    Hi,
    One customer have such data structure and have large number of data(arround 10 Million). I think it's proper to convert them to data that SQL loader can recognize and then insert into Oracle 8 or 9. The question is how to convert?
    Or maybe to insert them one by one is simpler?
    1: Component of Data
    The data file consists of nameplate and some records.
    1.1 Structure of nameplate
    ID datatype length(byte) comments
    1 char 4
    2 char 19
    3 char 2
    4 char 6 records in this file
    5 char 8
    1.2 structure of each record
    ID datatype length(byte)
    1 char 21
    2 char 18
    3 char 30
    4 char 1
    5 char 8
    6 char 2
    7 char 6
    8 char 70
    9 char 30
    10 char 8
    11 char 8
    12 char 1
    13 char 1
    14 char 1
    15 char 30
    16 char 20
    17 char 6
    18 char 70
    19 char 5
    24 bin(blob) 1024
    25 bin(blob) defined in ID19
    2: data file and table spaces in database
    dataID 1-13 of each record insert to table1,
    14-18 to table2, and 19,24,25 to table3
    Is there a method to convert them to some data that SQL loader can input and then at a whole load into Oracle 8 or 9?
    I've check the Oracle Utilities docs, but did not find a way to load so many data files at a batch action.
    In my view the solution consist in two ways:
    1, Load each of them individualy individually to different tables by some programme. But the speed may be problem because the uninterrupted db connections and close.
    2, Convert them to one or three files then use SQL loader.
    But either isn't much easy, I wonder if there's a better method to handle.
    Many thanks!

    My coworker tried that, but it dragged down portal.
    How about to update WWDOC_DOCUMENT$ table, then use WWSBR_API.add_item_post_upload to update folder information etc.?
    If possible, is there any sample code?

  • Load balance data files

    Hi,
    I have heterogeneous sources (txt,foxpro,ora tables etc) to be loaded to SQL Server, which I've SSIS pkg working fine to load these data sources . I need to do a load balance to check the records in the file to compare it with loaded rec in sqlserver tables.
     Please guide me with the logic to start with, also if there are any generic code available which can be edited to use for load balancing. 
    Thanks
    Neil

    Thanks Ernest,
    I have a business requirement to fail the pkg at error.  Hence I need to count the rows from the source file itself, is this possible, or will have significant impact on performance.
    Hi Neil,
    I would suggest you post the detail error message and elaborate it with more detail. As Ernest's suggest above, we can use "Row Count transformation" which counts rows as they pass through a data flow and stores the final count in a variable.
    For detail information, please refer to the articles below:

    it seems that the target you're loading to is already locked by another load...if it concerns a master data is also possible that the master data is locked by a change run. check your scheduling and make sure you don't load the same target at the same moment...
