• ADF: How to manage the value zero when downloading the csv file

  Dear all,

  I'm new in the ADF and use 12.2.1. I am downloading of data in the database using af table: inputfile and CSVParser class. Data download correctly in the database where all columns are met, but whenever the csv file has value null (empty) in his column, then CSVParser class does not recognize it and get the next value of columns and assign the previous column. I also tried another one that uses a different class to download date but not get success.

  For Ex:

  ID name Dept

  1 abc Dept1

  2 cde Dept2

  3 Dept3

  In example above two first line are perfectly inserted in the table while the third line Id goes to ID column, due to the value of the column name is null class CSVParser does not recognize it and put Dept3 in the name column.

  Please help how to handle this.

  Thanks in advance.

  Kind regards

      br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
      String line = "";
      while ((line = br.readLine()) != null) {
           String[] csvCols = line.split(",");
           // do somethinig smart with csvCols
      }
  }finally{
      if (br != null) try{br.close();}catch(Exception ex){br = null;}
      if (is != null) try {is.close();} catch(Exception exxx){is = null;}

  Hi Joseph,

  What is the file format of the file you are trying to download?

  This problem normally occurs when the Media player could not play the file downloaded or not supported.

  Method 1:

  Step 1: Here is the list of the formats supported by Windows Media player file:

  Information on the types of media files that supports Windows Media Player:

  http://support.Microsoft.com/kb/316992

  Note: See if the file format is in this list, if it is not there, you may need a third-party codec that can read the file.

  Step 2: For more information about codecs, see article given:

• How to download the Csv file with column headers

  Hi all

  This is pavan, using Apex version 4.2.3

  
  

  I am trying to download the csv file I followed this link , and I'm able to download excel with headers, when I try to download with headers of this error "'ORA-01858: a non-digit character was found here where was waiting for a digital" I searched in google but could not find the right solution, "

  
  

  can anyone help on this please.

  Thanks in advance,

  
  

  Kind regards

  This article is 6 years old.

  You should study the solutions that are available for APEX 4.2: data loader or the 'Excel2Collection' plugin (which also manages the CSV files).

  Data Loader

  It is a wizard that generates an Assistant for your application.

  Excel2Collection

  You will use the Excel2Collection (in a single process) to convert the BLOB in a Collection

  Then, in a 2nd address), you just do a "INSERT...". SELECT statement.  Add ' where seq_id > 1 "for files with a header.

  MK

  PS - Use the "EXECUTE IMMEDIATE" article is not necessary.

  I load this XML data file into a single table using an external Table. Could someone help me please with coding.

  Thank you

  Reva

  Could you please help me how to insert my XML content into that.

  Same as before, try a plain old INSERT:

  insert into xml_pecos

  values)

  XmlType (bfilename ('XML_DIR', "test.xml"), nls_charset_id ('AL32UTF8'))

  );

  But you'll probably hit the same limitation as with the binary XMLType table.

  In this case, you can use FTP to load the file as a resource in the XML DB repository.

  If the XML schema has been registered with the hierarchy enabled then the file will be automatically inserted into the table.

  Could you post the exact statement that you used to save the scheme?

  In the meantime, you can also read this article, I did a few years ago, it covers the XML DB features that may be useful here, including details on how to load the file via FTP:

  https://odieweblog.WordPress.com/2011/11/23/Oracle-XML-DB-a-practical-example/

• Load the XML file into oracle using sql loader

  Hello
  
  I'm trying to load an xml file into a table using sqlldr.
  I have a table as follows:
  

  CREATE TABLE xmlloadtable
  ( id number,
   data_xml XMLType
   )
    XmlType data_xml STORE AS CLOB;

  I have a control file that I know is perfectly false:
  

  LOAD DATA 
  INFILE '/home/oraread/'
  INTO TABLE xmlloadtable 
  (
  id,
  data_xml 
  )

  I googled for the file control and tried in different ways, but of no use.
  I want to load the entire xml file into the table.
  Can someone help me with the correct control file. Any help is appreciated!

  Try this

  LOAD DATA
  INFILE '/home/oraread/'
  INTO TABLE xmlloadtable
  (id,
   file_name          filler,
   data_xml          lobfile(file_name) terminated by eof
  )
  

  You can add the file as a column name field to your table between the id and xml column and remove the word to fill in the .ldr file if you need to keep the name of the file

• Problem with the date when you load the XML file into Oracle Database 10g

  Hi all
  
  I have the interface as shown in the screenshot below. In this document, among other things, I am mapping to an element XML file representing a date to an Oracle table column defined as DATE. The source and target columns are highlighted in the screenshot.
  
  ! http://img223.imageshack.us/img223/1565/odiscr275.jpg!
  
  When I run the interface, I get the following error message:
  
  java.lang.IllegalArgumentException to java.sql.Date.valueOf(Date.java:103)
  
  I guess that this is the conversion of the date!
  
  I already tried to replace SRC_TRADES. DEAL_DATE with TO_DATE (SRC_TRADES. DEAL_DATE, ' DD/MM/YYYY') on the implementation tab. This feature was not recognized when I executed the interface, so it did not work! The value of date in the XML file is in the format DD/MM/YYYY .
  
  I guess that Date SQL Oracle functions do not work in the implementation tab. Could someone let me know:
  
  1. what the Date Conversion function I could use instead?
  2. where can I find a reference to the methods/functions that I use in the implementation tab (if such a reference exists)?
  
  See you soon.
  
  James

  Hello.

  Try changing the area of execution at the staging area. Once you change it, write in the map box just SRC_TRADERS. DEAL_DATE. When you use TO_DATE, the source field typu should be varchar2, no date (as it is in store for your data source)

• Question to load the XML file into Oracle via ODI: LKM and IKM adjustment

  Hi all
  
  I am currently building an ODI interface to upload my file system XML local in a 10 g to Oracle database.
  
  I received the error message shown in the screenshot below:
  
  ! http://img529.imageshack.us/img529/3491/odiscr175.jpg!
  
  The main problem I have is, I don't know all what LKM or IKM assign.
  
  Can someone offer any assistance/advice?
  
  Thanks in advance.
  
  James

  James
  You must select the LKM SQL for Oracle (or LKM SQL for SQL) and then within Oracle to integrate Oracle the IKM incremental update or append IKM SQL command.
  Reading XML, you can just use the standard SQL KMs. (when writing, there's a little more necessary artifice, and this can be done by using specific IKMs)
  Hope this helps
