• External table with the preprocessor file to display the list of files

  Hello

  in my db 11.2.0.2 I would create an external table with script preprocessor to show me the list of files in a directory.

  Preprocessor banally:

  #! / bin/bash

  CD/MyDir

  / bin/ls-l *.txt 2 >/dev/null

  The problem is the file name that contains white space (style windows in a Linux env), for ex:

  -rw - r - r - 1 oracle oinstall 920 9 Jun 17:37 File1.txt

  -rw - r - r - 1 oracle oinstall 72316 Jun 10 10:37 file GC output1.txt

  -rw - r - r - 1 oracle oinstall 72316 Jun 10 10:40 GC file output2.txt

  So I can't use FIELDS DELIMITED BY "". ""

  FIXED size? No, because the file size change the length of the lines.

  I tried to use awk in my preprocessos script, but I have the same problem:

  
  

  / bin/ls-l *.txt 2 >/dev/null | / bin/awk ' {printf "%s %.2d %s %s\n", $6, $ 7, $ 8, $9} '.

  
  

  Any ideas?

• can bind us a single external table with multiple files in OWB 11 g?

  Hello
  
  I wanted to ask if it is possible to link an external table with several source files in same or different places? Or an external table must be bound to a single source file and one place.
  
  Thanks in advance,

  Hello Ann,.

  Can you please help me by telling me the steps to achieve this.

  Right-click on the external table in the project tree, from the menu choose Configure.
  then open right clock the node data files dialog Configuration properties and choose from the menu - Create
  you will get a new record for the file - name of file data property

  Also the link of the OWB user guide

• Several flat_files through the external table with only the common columns of loading

  Hi, I have 50 flat files and each of them have some columns (fields) common and I need to load only the fields that are common to an external Table. Is any chance to do it with education unique external table. Or I need to load all flat_files at separate tables and then with the ETG and UNION load them only one table.

  If the page size for all the files are different, I think that your only option would be to define different external tables and create a view that joins all the.

• External table with mixed columns

  Hello everyone. We use Oracle 11R1. We have an external table pointing to a CSV with 7 columns inside. The file has always column 7 but the column order differs from time to time. Each column has a header that remains consistent. Is there a way to map the column names to the column header, s so that we did not change the definition of the external table every time a new file is available in?

  Thank you.

  Hello

  As John said, you must assign names of columns when the table is created.  I guess you could have a dynamic SQL solution that reads the header you mentioned, uses this information to write a CREATE table, drop the table, and then recreated with the new order of the columns.

  You may have a view that maps the 7 columns in your table of 7 columns in the view.  Which column gets the mapping to that may depend on the header.

  But if I see the file I saw that BMW.

  My question is, in this case the external table loading must fail right? Why is this it is to load data in DB?

  Do you have this file begin life on windows, and then are transferred to * nix to serve an external table?  If so, which explains a lot.  Windows is the standard record delimiter x '0d0a' (Chr (13) 10)  On * nix, it's just x '0A' (10.  When the process of loader is scanning for record delimiter he's just looking for the '0A' x and x'd 0' gets included in the data.

  Two solutions-

  1 - Make sure that the data file is transferred so that the Records delimiters are converted.  It's supposed to to happen with ascii ftp mode, but this week I saw several examples in the House of it does not.

  2. attach your table definition external to seek the delimiter of actual recording instead of the default value of the operating system. == RECORDS DELIMITED BY X '0D0A '.

• Error when calling a procedure using an external table with c#.

  Hello

  I'm developing an application scheduler with Visual Studio 2010 (c#) to start my PL/SQL procedures.

  Everything works fine with each procedure, but one who reads the contents of an external table.

  Strange thing is when I start the same procedure with Toad, I have no problem, but when I run with my c# code:

  OracleCommand cmdMET = new OracleCommand();

  cmdMET.CommandText = 'STG_AE. M_MET_S_EXT_DEFECT ';

  cmdMET.CommandType = CommandType.StoredProcedure;

  con = cmdMET.Connection;

  Thank you!

  I can't understand why it works when I run it with Toad and why I get this error when launching of it with c#... Any advice would be great!

  The error led to think that a string to number conversion fails all by accessing the external table.

  What is the format of numeric fields in the external file?

  I'm guessing that your session NLS_NUMERIC_CHARACTERS setting is defined differently whether you're in your application c# or toad.

  Could check you on both?

• External table with the empty file

  Hello

  My version of db: Oracle 11 g

  I have a csv file that is empty.

  I created an external table the empty csv file.

  When I run:

  Select count (*) in the externaltblname;

  It returns 1.

  It should return 0 to the right.

  In the definition, I specified "SKIP 1.

  But he always returns 1.

  When I use this external table to load into a table target. It loads a single row with null values.

  How to solve this problem. Please advice.

  What works for me is the following (t_ext points to a blank csv):

  SQL > select count (field) in the t_ext;

  COUNT (FIELD)

  ------------

  1

  1 selected line.

  SQL > select ascii (field) in the t_ext;

  ASCII (FIELD)

• JDBC and creation of external tables with positions

  Hello
  
  This could be a trick question or I'm probably going in circles with this one. I know that it is not possible to call the pl/sql command ("together define") using a jdbc connection. Correct me on this one, if I'm wrong ;)
  
  So what I want because I want to run the following using a CallableStatement stmt:

  command prompt
  
  CREATE TABLE 'TEST '. "" TEST_RECEIPT_EXTERNAL ".

  )
  LOCATION

  that gives me the expected error:

  Use a regular statement. There is no reason to DDL like that with a callable statement.

• When to load the external table condition

  
  Hello

  Is my version of db: oracle 11g

  I have a 6 gig csv file.

  I divided it several 15 MB csv files.

  But only the first csv file has header (with column headers).

  I have to load each of these files into a target table.

  I created an external table with jump 1.

  But how can I substitute jumping 1 for other csv files.

  Is there a way I can do it in the external table definition.

  I can't merge the split csv files and run as one big file. So I don't hv this option. Please advice.

  You should be able to use the LOAD WHEN clause to exclude a line based on the contents of a field. Or the other

  WHEN LOAD 1 / 2! = "ID".

  or, if the bonds are quoted,

  WHEN LOAD 1:4! = « « ID » »

  or you can always add a list of fields to your specifications and the names of the fields in the reference LOAD WHEN the condition instead of using an absolute position.

  Don't know if you saw my comments on the use of the tail command before you replied, but if the break-up of the file is part of your project of automated process, and then deleting the header row could certainly be integrated into this process if your on a unix platform and using the split command to split the file.

• field of varchar2 external table storing only 255 bytes (4000 bytes)

  Hi all
  
  I was wondering if someone can tell me what im missing here.
  I have an external table with one column defined as varchar2 (4000 byte). the file contains a line with 255 characters (all the number 2 for simplicity). When I query the table, everything is fine. If I add 1 plus 2 chain (256 characters) it fails. im sure its something stupidly simple, but what am I missing? If he doesn't have to question fine up to 4000 characters?
  
  Thank you
  Dave

  I ran your testcase, thanks for that.
  Make sure you read the SQL and PL/SQL FAQ as well (the first thread sticky on this forum), he explains how to post the code formatted and many other things.

  In any case, the .log file gave me:

  LOG file opened at 07/18/11 20:05:33
  
  Field Definitions for table DAVEP2
    Record format DELIMITED, delimited by 0A
    Data in file has same endianness as the platform
    Rows with all null fields are accepted
  
    Fields in Data Source: 
  
      MY_STRING                       CHAR (255)
        Terminated by ","
        Enclosed by """ and """
        Trim whitespace same as SQL Loader
  

  So, what happens if you create the table as follows:

   CREATE TABLE davep2 (
     my_string         VARCHAR2(4000 BYTE)         NULL
   )

    FIELDS TERMINATED BY ',' optionally enclosed by '"' and '"'
    missing field values are null
     (

• External table Oracle via the Tables API

  Hello world

  I did experiment with the Oracle NoSQL database recently and I became a bit stuck with the new API of Tables. I have so far successfully of the external tables on the data entered using storage techniques 'vanilla' KV and avro (using generic and specific links) scheme, but create API Tables seems to be another matter entirely.

  My question arises in the trainer interface, which has a KeyValueVersion and a KVStore. I can't translate a KeyValueVersion created with the API of Tables in a primary key for recovery (since I don't know what the key generated by the API actually looks like to!) or map it on an avro scheme. The problem seems to be that the Tables API writes data in some format that can be easily translated into a string or an integer (releases from external table lines due to unknown characters if I am trying to retrieve all the values in the database to see what it looks like to), and try to map it to an AVRO map results in the error message 'the data are not as AVRO'.

  Scenario:

  I created a very simple table in the administration tool KV, which consists of a column personId (integer) that is PK, firstName, lastName, emailAddr (all channels) and enter 5 rows with success. What I want to do is to create an external table called person that returns just those 5 values (and brand new I add to the table of course). This means that I have to first understand what the parentKey value must be defined in the .dat file and how to take this key and it becomes a primary key for the recovery of the line.

  Faithful old Google could not find information on how to do this (he was only a thread similar to this with the answer "we'll add it soon"), so I hope that someone here managed to do!

  Thank you

  Richard

  Hi Richard

  I understand the issue you are facing. In the current version (12.1.3.0.9) the external tables feature only works with records of K/V not with the Table model, however, in the next version (which us will very soon be GA) we will support integration of external tables with the data of Table model as well. Please make sure that you have signed up for the announcement of release so that we can inform you of the release. I apologize for the inconvenience, he did to you.

  Best
