• 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?
  

  Hello

  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

• 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
   )
   ORGANIZATION EXTERNAL
     (  TYPE ORACLE_LOADER

    LOGFILE FILE_TEST:'davep2.log'
    FIELDS TERMINATED BY ',' optionally enclosed by '"' and '"'
    missing field values are null
     (
             my_string char(4000)
             ) )

• Several links in the single column

  Hello

  I have a requirement to display several links in the single column.

  Example:

  Select emp_name emp #, total_days days, col3, col4 from table

  Here, I need to display a link beside the example of days

  If day > 100 then display "101 CH" where 101 days value and CH is the URL link which will open a popup page. I can't have another column for the link that we have already several columns. So I need a way to display the link with the value next to him. How can I achieve this?

  try to put it in the source of the region

  Select emp_name, emp #,.

  -case when days > 100 then days | " http://Google.com" target = "_blank" > popup' another to_char (days) end total_days, "

  col3, col4 from table;

  This should display "101 popup" when the days more than 100, no popup link on days<= 100="" e,g="" "99"="">

  and the value of the column total_days to the "Reporting Standard column" to allow html tags.

  Change the href attribute and formatting to meet your requirement

• Removal of several tables with only loop FORALL

• 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)

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

  13

  1 selected line.

  SQL > select count (replace (field, chr (13))) of t_ext;

  COUNT (REPLACE (FIELD, CHR (13)))

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

  0

  1 selected line.

• Loading external Table with quotes

  Example:

  ----------

  "BMW".

  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 '.

• 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.

• 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;

  OracleParameter retvalMET = new OracleParameter ("value", OracleDbType.Varchar2, 50);

  retvalMET.Direction = ParameterDirection.ReturnValue;

  cmdMET.Parameters.Add (retvalMET);

  cmdMET.ExecuteNonQuery ();

  I got this error:

  ORA-29913: error in executing ODCIEXTTABLEFETCH legend

  ORA-01722: invalid number

  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!

  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?

• The script generation is not supported for Table with XML or UDT column Types

  I get this message trying to generate a script to create a table with an XMLTYPE column.  We use the Oracle Developer Tools for Visual Studio to generate scripts as SQLDeveloper does still not support TFS integration.  He was always pretty easy to generate scripts and maintain control of source code in this way (with the exception of materialized views).  It was great, just right click and generate a script for the project and check it in.  Unfortunately as the adoption of XML grows, we find passage to the SQL Developer more often to perform tasks not supported and then return to the VS IDE to manage source code control.  Free of any chance that it will be supported in the future?

  Yes, our plan is to support several types as time goes by.

  You possibly can speed things along by voting or by filing a request for new feature here:

• primary key for a table with only 1 column

  I create a temporary table in my procedure and there is only a single column in it. I'll eventually use this temporary table in a join. Does make sense to create a primary key for this temporary table? It will make my join run faster? In other words, oracle automatically sorts and keeps the table column is the fact that if a primary key or index is created? I use 10g - 10.2.0.3.0

  The data table is not indexed.

  Oracle will probably make a hash join.
