External table-> fetch location?

With the help of Oracle 10.2.0.5

An external table is a construction that gives me access SQL to a file.

Is it possible to know the name of the file somehow inside to select? Like to add a column with the name of the file?

example of Pseudo 
CREATE TABLE EXT_DUMMY
(
    "RECORDTYPE" VARCHAR2(100 BYTE), 
    "COL1" VARCHAR2(100 BYTE), 
    "COL2" VARCHAR2(100 BYTE), 
    "FILE" VARCHAR2(100 BYTE) 
)
ORGANIZATION EXTERNAL
(
    TYPE ORACLE_LOADER DEFAULT DIRECTORY "IMPORT_BAD_FILE" 
    ACCESS PARAMETERS ( 
             records delimited BY newline 
             FIELDS TERMINATED BY ';' 
             MISSING FIELD VALUES ARE NULL 
               ( RECORDTYPE CHAR
               , COL1 CHAR 
               , COL2 CHAR 
               , FILE CHAR FILLER
               ) 
               ) 
    LOCATION ( 'Testfile1.txt, Testfile2.txt' )
)
    reject limit 10
;
The result might look like this:
RECORDTYPE   COL1       COL2      FILE
SAMPLE           DUMMY    DUMMY Testfile1.txt
SAMPLE           DUMMY1   DUMMY Testfile1.txt
SAMPLE           DUMMY2   DUMMY Testfile1.txt
SAMPLE           DUMMY3   DUMMY Testfile1.txt
SAMPLE           DUMMY1   DUMMY1 Testfile2.txt
SAMPLE           DUMMY1   DUMMY2 Testfile2.txt
SAMPLE           DUMMY2   DUMMY1 Testfile2.txt
I would like to know what file is read a certain rank. Maybe I missed an option in the documentation. In this example, I have two different files as the source for the external table.

Another use case could be that:
If I enable a user to switch the external table to a different file
alter table EXT_DUMMY location ('Testfile3.txt' )
. How do know us which file is read during the select on the table? When UserA's select, perhaps UserB just modified the location before that selection has been started. That's why UserA reads in a different file than expected.

Hi Sven,

I don't know how much we can rely on that, but we will consider the following:

create table test_xt (
  rec_id  number
, message varchar2(100)
)
organization external (
  default directory test_dir
  access parameters (
    records delimited by newline
    fields terminated by ';'
  )
  location (
    'marc5.txt'
  , 'test1.csv'
  , 'test2.csv'
  , 'test3.csv'
  )
);

I always thought that the ROWID doesn't hold much meaning for an external table, but...

SQL> select t.rowid
  2       , dump(t.rowid) as rowid_dump
  3       , regexp_substr(dump(t.rowid,10,9,1),'\d+$') as file#
  4       , t.*
  5  from test_xt t
  6  ;

ROWID              ROWID_DUMP                                                FILE#      REC_ID MESSAGE

Seems to work... assuming that the files are always read in the order specified by the LOCATION parameter and the ID generated actually means what I think it means.

    Combination dump files

    Files dump populated by different external tables can all be specified in the LOCATION of another external table clause. For example, data from different databases can be unloaded in separate files, and these files can then be included in an external table defined in a data warehouse. This provides an easy way to aggregate data from multiple sources. The only restriction is that the metadata for all external tables is exactly the same. This means that the game characters, time zone, schema name, table name, and column names must match. In addition, the columns must be defined in the same order, and their data types must be identical. This means that after you create the first external table you must remove it so that you can use the same table name for the second outer table. This ensures that the metadata in two dump files is the same and they can be used together to create the external table even.

  • External table - interprated as link to a file location

    Hello everyone,

    I'm usigng of external tables for the first time. I using DB version 11.2.0.1.0

    I do the following:

    Create the directory:

    create the directory lip_test_dir as ' / daten/file_test/XML ";



    Create an external table

    CREATE TABLE lip_test (clob data)

    REJECT LIMIT UNLIMITED;


    try to select data:

    Select * from lip_test;

    I get the following error:

    Check the log file shows me that the charger open the xml file and tired to open for each line in the xml file, a new file. Messages are looking like this:

    If <? XML version = "1.0" encoding = "UTF-8" standalone = 'no '? > is the first line in the XML file and tries to open it as a file.
    This is repeated for each line in the xml file.

    Can someone explain to my why this is happening. I have queryed www for this, but I don #t know what question exectly, so I found no useful result.


    I tried the following:

    Re-create the table and use a text file "test.txt" as location

    CREATE TABLE lip_test (clob data)
    EXTERNAL ORGANIZATION
    (
    TYPE ORACLE_LOADER
    Lip_test_dir default DIRECTORY
    ACCESS SETTINGS
    (
    FIELDS (lobfn TANK CANCEL BY EOF)
    TURNS COLUMN (data FROM lobfile (lobfn))
    )
    LOCATION ("test.txt")*.
    )
    REJECT LIMIT UNLIMITED;


    In the test.txt file I just put the name of the XML file, so the value of the test.txt is

    2011103052820853_erp2eip_iteminventory_xml. XML


    Subsequently I query the table again:

    Select * from lip_test;

    No error just now came up! and the query shows me all the lines of 2011103052820853_erp2eip_iteminventory_xml.xml.

    I expected to see only the name of the file as it is written in test.txt, bt now I get the result that I expect when I put location (2011103052820853_erp2eip_iteminventory_xml.xml).


    Anyone know why this is happening?

    Thanks a lot for your help!

    Best regards from Germany

    You will need to use the second approach, you mentioned above, with a file "test.txt" separate containing the name of the source.

    My question is - is it possible for me to fix this error at the level of external table definition? Please advice
    			 
    Yes it is possible.  Let's not your date mask.  You're masking for 12-hour format when your data is in 24-hour format.  Change the mask of your date to be "YYYY-mm-dd-hh24. MI.ss ".  Notice the change in "BOLD".

    Pretreatment of an external table - table is empty at the end
     
			 
    Hello

    I'm trying to create an external table that first pre-process a file and then the bed. The problem is that, in the end, the outer table is empty even if the read file is not empty.
    First, the table works gunzip on the 'employees.csv.gz' file located in/export/home/oracle/archives and then bed. The file  employees.csv.gz exists in the specified location. This is the complete script:
    -This Directory keeps the archived files
    CREATE or REPLACE DIRECTORY arch_dir AS 'archives/export/home/oracle/archives";
    -This directory shows where the command gunzip
    CREATE or REPLACE the bin_dir AS DIRECTORY ' / usr/bin';

    )
    )
    LOCATION ("employees_exp.csv.gz")
    )
    REJECT LIMIT UNLIMITED;
    When I choose to  emp_exadata the result set is empty!
    SELECT * FROM  emp_exadata; 
    no selected line
    When I look at the db server in the directory  /export/home/oracle/archives I see no archived file employees_exp.csv. Here is the result of the first three lines:

    bash - $3.2-3 employees_exp.csv head

    The end of the lines in the file line is LF (unix style). The encoding is in ANSI format.
    I tried to experiment around, but cannot view records when I select in the external table. Please help me to solve it.
    I also register the generated log file:

    You need to carefully examine the description of the PREPROCESSOR option in the chapter of the manual external Tables utility.
    

    The first point that applies to your question is that the preprocessor must write its data transformed to stdout. To do this with gunzip, you use the - c command line parameter. The second point that applies to your case, in view of the answer to the first point, is that you must write a script shell if your preprocessor requires command line settings.
    

    Kind regards

    Loading external Table with quotes
     
			 
    I have a file with fields in the file are as TAB delimiter ~ TAB.
    Example as below:
    QM ~ CD ~ Exzm ~ BMW
    DM ~ BD ~ Exzm ~ BMW
    CREATE TABLE test
    (
    Col_1 VARCHAR2 (100),
    Col_2 VARCHAR2 (100),
    Col_3 VARCHAR2 (100),
    Col_4 VARCHAR2 (100)
    )

    (TYPE ORACLE_LOADER
    DEFAULT DIRECTORY 'Test_Report '.
    ACCESS SETTINGS
    (records delimited by '\n'
    CHARACTERSET 'UTF8 '.
    fields terminated by '\t~\t '.
    missing field values are null
    )
    LOCATION ("test.asc")
    )
    REJECT LIMIT UNLIMITED;
    OUTPUT:
    ----------------
    Data loaded in DB, but col_4 data comes from the quotation as below
    col_4
    -------
    "BMW".
    "BMW".
    Note: Col1 - col3 data arrives correctly.

    A finding on my side.
    

    I found that the values of Col_4 after inserting into DB with "transport return character" (CHR (13)) at the end of each value as shown below when I copy paste the value in notepad ++ "»
    

    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 '.

    Battle of external table: files that contain only a picture
     
			 
    Hello
    Does anyone know if this is possible: use an external table to load files that each contain only one photo (photo) in a BLOB column?
    So: just a photo, not other columns and not many lines.
    I tried, in the sense of this article: ORACLE-DATABASE external Tables containing LOB -
    I'm starting to believe it is not possible due to the "delimited records by ' and 'fields terminated by' clauses, which are not really applicable given files (just a picture), but maybe (hopefully), I'm wrong.
    Any pointer is more than welcome!

    )
    Select * from XT_df
    And it works.  I see my df output.
    I want to run something similar on multiple hosts, but the same host, so I place another table and call another shell script to run a remote ssh script after I have set user equivalence
    / usr/bin/SSH oracle@remotehost1 ' df-h | grep u02'
    the works of shell script
    However, qualifying by selecting in the external table I get ssh host checking has no error.

    KUP-04095: order of preprocessor /winlogs/dfh.sh has detected the error "host key verification failed.
