Sqlloader Vs external Tables

HII All,
Currently, we use sqlloader. But now we are stuck to the top with a question. The problem is that in our production environment that they have installed customer sqlldr in the application server and the feed file in place in the Oracle server machine.

We tried everything to stay with sqlloader but nothing works very well. I tried with ftp to transfer the file from Oracle server to the client machine, but we use the secure port it did not work.

But this was easily accomplished using external table that the file is located in the server. But now I need to satisfy my clients by proving the external tables are relatively better.

I have google for Sqlloader vs. external this debate.

But I found no strong points supporting external tables.

I had also gone through the following links

http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:6611962171229

http://www.orafaq.com/Usenet/comp.databases.Oracle.misc/2007/02/13/0222.htm

So please help me by providing some plus points and other links.

Yes, it's really a good point, but can be achieved once the data has been pumped into staging tables.

Who would take more space on the database, while the external tables you can do anything as the data is read. External tables would seem better in this regard.

And now, we are not concerned with all the functions for use in DEC.

People argue with me if we use external tables, we need create objects 2 db (1 external and more temporary table) which is just 1 intermediate table if sqlloader.

You only need the external table definition. If you create a temporary table with this depends on your needs and the need to have such a table "staged." Even if you did in SQL * Loader you would always create a staging table, if there is really no difference...

External table = 1 table definition and no data loaded in the database
SQL * Loader = 1 table and the data loaded into the database

Also read that when the feed file is huge its better to opt for sqlloader as it can circumvent sql analysis by choosing a DIRECT approach. Isisnt it?

External tables using SQL * Loader under the hood engine, so there is no real difference except where you want to keep your data (in the file, or load a copy first on the database). You can use the parallel with external tables to load using multiple threads, you can use the indicator append to load the data as in the direct approach of sql * loader.

So, kindly suggest me which is the best approach in a long-term process.

In the long term, the external tables are the best approach. They were introduced after SQL * Loader to provide an improved mechanism. If they were not better, Oracle would not have taken the trouble with them. They also have the advantage that the control of their use is on the database, i.e. no need to control files, no need to run a command-line utility, not two floors (loading then treatment) treatment.

There is no real reason for the use of SQL * Loader everything but more, the strange unique circumstance where you need to download data from a client computer (which will raise the question why a client machine has data on it in the first place!)

  • Using the external table error

    Hi all

    This is the first time I use the external table for loading the data.

    I did these steps

    In the D:\sqlloade folder, I have my text file containing data example.txt

    is this the same hostname that you are connected?

  • Doubt of external Table

    Hi Master,

    Using Sql * Loader I can load the dat/csv/txt data to oracle tables. I can use it when clause contained in the data file and load control in different tables.

    e.g. when deptno = 20 then table 1. Where deptno = 10 then table2 etc...

    But using the external table... How can I load data in different tables as an example above? I googled. but do not get appropriate information. Please advise... !!

    The external Table storage
     
			 
    Since data is stored outdoors, and the definition that is stored inside, it means that a the table structure of the outer table is stored in the database as well (or a virtual table based on the definition of the external table...)
    I'll hit the ORA-DOCS again once, back in the external tables read tonight on them 2 or 3 sources and it is not quite clear whether real data with structure exists outside the database or an internal table set (and stored) retrieves data from an outside source.
    			 
    Since data is stored outdoors, and the definition that is stored inside, it means that a the table structure of the outer table is stored in the database as well (or a virtual table based on the definition of the external table...)
    

    The 'definition' you refer to IS the structure of the table; they are one and the same. There is no 'table' stored in the database using space or storage. When a query on an external table is executed, the data source is read.
    

    
I'll be hitting the ORA-DOCS up again, just got back into external tables tonight reading up on them from 2-3 sources and it is not quite clear if an actual data with structure exists out of the database , or an internally defined (and stored?) table draws data from an outside source.

    

    I suggest you that start with the documentation of Oracle - including the ground provided the link to:
    

    If any "metadata" are stored outside the database depends on if the file that is outside of the database was produced by Oracle using the robot UNLOADING discussed in this doc
    

    Unloading of data using ORACLE_DATAPUMP Access driver
    

    To unload data, you use the ORACLE_DATAPUMP driver access. The stream that is discharged is in a proprietary format and contains all of the data column for each row being unloaded.
    

    A discharge operation also creates a stream of metadata that describes the content of the data stream. The information in the metadata stream are required to load the stream. Therefore, the metadata stream is written to the file data and placed before the data stream.
    

    If YOU provide data/files, then you MUST provide it in the format expected by the external table statement. You can, if you wish, use a preprocessor to convert ANY file (zip, encrypted, etc.) in the required format.
    

    For YOUR files, you can the metadata stored in the same file, or elsewhere, if you choose, but Oracle will have NO knowledge of this fact and not will NOT be involved in the transformation or read any of the metadata that you provide. Your preprocessor must remove all these metadata and ONLY provide data in the format appropriate for Oracle to use.
    

    If the file was produced by the process of UNLOADING Oracle then it will include metadata that Oracle WILL read, use, and remove as says this quote from doc above. These external metadata is added to the real external table definintion/metadata stored in the dictionary.

    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".

    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.

    create an external table based on local drive
     
			 
    Hello world
    Is it possible to create an external table and that it points to a file on my local drive?
    It is perhaps a silly question. I'm sorry.
    Thank you
    Lydiea
    			 
    In addition to the response of William Robertson (which is correct), if you do not have a way to make the server access to your local disk, you can use sql loader on your local computer to load the data into an actual table.

    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:

    Pretreatment of an external table - table is empty at the end
     
			 
    Hello
    Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit Production
    PL/SQL Release 11.2.0.1.0 - Production
    "CORE 11.2.0.1.0 Production."
    AMT for Solaris: Version 11.2.0.1.0 - Production
    NLSRTL Version 11.2.0.1.0 - Production
    Solaris 10 x 86
    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';
    CREATE TABLE emp_exadata
    (
    employee_id NUMBER (22, 0),
    first name VARCHAR2 (20).
    last_name VARCHAR2 (25).
    e-mail VARCHAR2 (25).
    Phone_Number VARCHAR2 (20).
    hire_date DATE,
    job_id VARCHAR2 (10),
    higher wages (22: 2),
    commission_pct NUMBER 22 (2)
    manager_id NUMBER (22, 0),
    department_id NUMBER (22, 0)
    )
    EXTERNAL ORGANIZATION
    (
    TYPE oracle_loader
    Arch_dir default DIRECTORY
    ACCESS SETTINGS
    (
    RECORDS delimited BY NEWLINE
    preprocessor bin_dir: "gunzip".
    end fields BY «»
    missing field VALUES are NULL
    (
    employe_id,
    first name,
    last_name,
    E-mail
    Phone_Number,
    hire_date CHAR date_format DATE mask "dd-mm-yyyy hh24:mi:ss."
    job_id,
    salary,
    commission_pct,
    manager_id,
    department_id
    )
    )
    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
    198, Donald, Ollivier, DOCONNEL, 650.507.9833, 21/06/2007 00:00:00, SH_CLERK, 2600, 124, 50,.
    199, Douglas, grant, DGRANT, 650.507.9844, 2008-01-13 00:00:00, SH_CLERK, 2600, 124, 50,.

    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:
    LOG file opened at 01/06/15 16:40:11
    For table EMP_EXADATA field definitions
    Record format DELIMITED BY newline
    Data in file have same "endianness" as platform
    Rows with all null fields are accepted
    Fields of the Data Source:

    Trim whitespace same as SQL Loader
    DEPARTMENT_ID CHAR (255)
    Completed by «,»
    Trim whitespace same as SQL Loader
    			 
    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

    Access to an external table via the display in the UCM configuration manager problem
     
			 
    Hi all
    I know that this question is already asked here: to access the external tables in DB / in UCM Applet configuration manager but the conversation has already been archived, and I can't comment there. I'm following approach given by William Phelps in above said archived thread.
    I am able to create dblink with data remote and created the view by using the linked table in my diagram of the Complutense University of Madrid. The problem that I face is that this point of view such as told by William is not visible in the configuration manager. Although I tried to give (create view and create all views) system diagram University Complutense of MADRID user privileges, but I'm not sure that it will also provide access rights. I am using the SQL Developer and working at the University Complutense of MADRID 11 g.
    All comment or suggestion will be a great help.

    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)
    )
    EXTERNAL ORGANIZATION
    (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 '.

    Bulk insert in an external table
     
			 
    Hi, I get the error ora-29913, ora-01410 trying to do a bulk insert of external table
    INSERT
    IN CORE_TB_LOG
    (SELECT 'MODEL', 'ARCH_BH_MODEL', ROWID, "MODEL-D-000000001', - 45, 'A', SYSDATE, 'R'")
    OF ARCH_BH_MODEL1
    WHERE length (MOD_XCODIGO) > 10)
    INSERT
    *
    ERROR on line 1:
    ORA-29913: error in executing ODCIEXTTABLEFETCH legend
    ORA-01410: invalid ROWID
    ARCH_BH_MODEL1 is the external table.

    What's wrong?

    Thank you.
    			 
    Hello
    

    There is no ROWID in external tables.
    

    It makes sense: ROWID identifies where a line is stored in the database; It shows the data file and the block number in this file.
    

    External tables are not stored in the database.  They exist independently of any data file in the database.  The concept of an Oracle block does not apply to them.
    

    Why would you copy the ROWID, even if you could?
    

    Apart from ROWID and SYSDATE, you select only literals.  You don't want to select all the real data of the external table?
    

    What is the big picture here?  Post a small example of data (a CREATE TABLE statement and a small data file for the external table) and the desired results from these sample data (in other words, what core_tb_log must contain after INSERTION is complete.)  Explain how you get these results from data provided.
