Oracle 9i External Tables

Helllo Everyone.
I am new to external tables concept and I have only used using flat files.
Is there a complete reference on on external tables somewhere?
Also, instead of .csv or text based datafiles, can I use XML as data source for these external tables? If so, how?
Thanks,
R

The link to the documentation has been already posted.
About the xml as a possible datasource, in Oracle9i only the ORACLE_LOADER driver is supported, it allows you to read data using SQL*Loader, that is to say only plain text files.
In Oracle10g a new driver has been added: ORACLE_DATAPUMP, it allows you to read with an external table a dump file created from other Oracle tables using the same ORACLE_DATAPUMP driver.
Unfortunately the ORACLE_DATAPUMP driver doesn't support the XMLTYPE datatype:
SQL> desc tbl_xml
Nome                                      Nullo?   Tipo
XML                                                PUBLIC.XMLTYPE

5      DEFAULT DIRECTORY DATA_PUMP_DIR
6      LOCATION ('xml_ext.dmp')
7    )
8    AS SELECT * FROM tbl_xml;
CREATE TABLE xml_ext
ERRORE alla riga 1:

I don't think this is a SQLDeveloper issue. You will get better answers in the Database - General or perhaps SQL and PL/SQL forums.

We are using Oracle 11g (11.2.0.1.0) on (Platform : solaris[tm] oe (64-bit)), Sql Developer 3.0.04
We are not allowed to put files on the CSV file system (Server A), where DB instance is running. We are able place CSV files on another server(Server B), where DB instance is not running.
We are trying to use oracle external table to load text files in .CSV format.
How do we create a Directory (Create Directory) on Server A DB to point to File system of Server B?
Is it feasible?
Any idea?
Thanks in helping.

The Solaris DBA should be able to mount the filesystem for you. Either that or you have to get creative transferring the file like this;

I'm not sure, but maybe you should get rid of the redundancy that you have in your CREATE TABLE statement.
This line covers all fields:
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'
{code}
So I would change the field list to:
{code}
DATE1 CHAR (10),
DATE2 CHAR (10),
POL_PRTY CHAR (30),
P_NAME CHAR (30),
P_ROLE CHAR (5)
{code}
It worked on my installation.

Accesing windows files using oracle unix external tables.

Hi, I'm trying to access files on windows2k using oracle external tables on unix:
Oracle server on unix: oracle ver. is 9.2.0.6 and OS is 5.8 Generic_117000-03 sun4u sparc SUNW,Sun-Fire
1. Created dir object on oracle unix pointing to windows path
2. created user
3. Assigned read and write privs on dir to user
4. created external table using dir step 1
5. select on external table
When I FTP the files into unix and recreate dir object, it works, but if I point dir object into windows path, it fails.
Is possible to do this?
Tks
GAP

Hi
The directory object must be accesible to your Database server, so if the Database is in unix you must create the directory in unix.
I don´t know software that allow unix systems to see a windows file system. Maybe windows can see unix from a samba server or NFS.

External tables in oracle 8i

Hi,
I am working in Oracle 8i. I need to use Oracle 8i External Table to load data in the database. But I am getting the following error
ORA-00922: Missing or Invalid Option
The snippet which I used is as follows:
create table ext_table_csv (
a NUMBER,
n NUMBER,
m NUMBER
organization external
type oracle_loader
default directory swami
access parameters (
records delimited by newline
fields terminated by ';'
missing field values are null
location ('sample.txt')
PARALLEL
reject limit 0
The input file data is
018307;20080421;123457
018307;20080421;123457
Please let me know how this can be done in Oracle 8i and I have to use Oracle Loader only.

Its a new feature introduced in Oracle 9i.
http://download.oracle.com/docs/cd/A91202_01/901_doc/server.901/a90120/ch2_feat.htm#58871
For 8i, SQL*Loader is the only option.

XML File in External Table - OS error permission denied.

Hi.
10g R2, Red Hat Linux
I'm using the article (see below, taken from http://www.dbazine.com/olc/olc-articles/scardina1 by Mark Scardina) to create an external table where I'd store my XML file.
So, I
1. Created a directory xmlfile_dir
2. Granted access to needed db user
3. Created the table
CREATE TABLE relayxml_xt (doc CLOB)
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY xmlfile_dir
ACCESS PARAMETERS
FIELDS (lobfn CHAR TERMINATED BY ',')
COLUMN TRANSFORMS (doc FROM lobfile (lobfn))
LOCATION ('xml.dat')
REJECT LIMIT UNLIMITED;
4. mv relay.xml /xmlfile_dir/xml.dat
When I run SELECT * FROM relayxml_xt I get this:
Error starting at line 1 in command:
select * from relayxml_xt
Error report:
SQL Error: ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-04063: unable to open log file RELAYXML_XT_28773.log

29913. 00000 - "error in executing %s callout"
*Cause:    The execution of the specified callout caused an error.
*Action:   Examine the error messages take appropriate action.
What am I doing wrong?

Using External Tables
Introduced in Oracle9i, Oracle’s external table feature offers a solution to define a table in the database while leaving the data stored outside of the database. Prior to Oracle Database 10g, external tables can be used only as read-only tables. In other words, if you create an external table for XML files, these files can be queries and the table can be joined with other tables. However, no DML operations, such as INSERT, UPDATE, and DELETE, are allowed on the external tables.
Note: In Oracle Database 10g , by using the ORACLE_DATAPUMP driver instead of the default ORACLE_DRIVER, you can write to external tables. In Oracle Database 10g, you can define VARCHAR2 and CLOB columns in external tables to store XML documents. The following example shows how you can create an external table with a CLOB column to store the XML documents. First, you need to create a DIRECTORY to read the data files:
CREATE DIRECTORY data_file_dir AS 'D:\xmlbook\Examples\Chapter9\src\xml';
GRANT READ, WRITE ON DIRECTORY data_file_dir TO demo;
Then, you can use this DIRECTORY to define an external table:
CREATE TABLE customer_xt (doc CLOB)
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY data_file_dir
ACCESS PARAMETERS
FIELDS (lobfn CHAR TERMINATED BY ',')
COLUMN TRANSFORMS (doc FROM lobfile (lobfn))
LOCATION ('xml.dat')
REJECT LIMIT UNLIMITED;
The xml.dat file follows:
customer1.xml
customer2.xml
If you describe the table, you can see the following definition:
SQL> DESC customer_xt;
Name Null? Type
DOC CLOB
Then, you can query the XML document as follows:
SELECT XMLType(doc).extract('/Customer/EMAIL')
FROM customer_xt;
Though the query requires run-time XMLType creation and XPath evaluation, this approach is useful when applications just need a few queries on the XML data and don’t want to upload the XML data into database. In Oracle Database 10g, you cannot create external tables that contain pre-defined XMLType column types.

Your don't have the proper operating system privileges. Be sure that you (=oracle OS user / the OS Linux user that is starting the database) are allowed have read privs on the path and/or file.
for example...
chown -Rf /xxxxxxx/xxxx/etc
ls -l file.xml
file.xml    oracle:oinstall    rw-rw-rw

Position in external table

We have excel spread sheet.
We wanted to load data from excel spread sheet to Oracle via external table.
I saved my file into .txt format.
No I need to create external table in oracle DB.
my question is as follows:
Do I need to define exact lenght of datatype per data?
Now data of column city take 16 slots in data file.
But I defined size 30, is it ok?
SQL>CREATE TABLE External_City
CITY VARCHAR2(30),
STATE VARCHAR2(20),
ZIP VARCHAR2(10),
COUNTRY VARCHAR2(30)
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER

Do we need to define data position in external table?

I do not think it has to do with your data or positon of data in it. I am not sure what or where your file is. You need to ensure accessibility to it. it is not seeing the file at all.
BTW - avoid using udump location as your directory location. Change the directory location (I am not saying it is the cause).
Here is my test. Although my class.dat file is empty, it shows that your external table should work once your file and directory is accessible. I have only replaced DATALOAD with mytest_dir

When will external table field_list in access parameters support varchar2?

Hello all,
Currently I'm working on a CSV error check/upload/download utility (in pl/sql) using external tables. However, within the access parameters section, when I tried to use varchar2 in the field list to map to data fields in csv, oracle (10g) complaint that I cannot use varchar2.
Therefore I am forced to use char (Feuerstein explictly told us not to use varchar in PL/SQL Programming) to map to the data. However, since some fields in the DB are actually varchar2(4000), and the max length supported by char type in sqlplus is 2000, I'm creating this ridiculous machine:
- data in csv can hava a maxlength of 4000 characters
- staging table to which csv data will go to is varchar2(4000)
- field list in external table creates a bottleneck of char(2000)
As a result, I'm betting on the user never will enter any string longer than 2000 character into csv, even though the DB supports it. However, this would be way too fragile to go into production.
Does anybody know if Oracle 11g external tables support varchar2, or are there any workarounds (besides using sqlldr)? Many thanks.

Hi, my external table spec is something like this:
create table x_table (
field1           varchar2(4000),
field2           varchar2(4000),
field3           varchar2(4000))
organization external (type oracle_loader default directory ext_tab_dir
          access parameters (
          records delimited by newline
          badfile ext_tab_dir:'importcsv.bad'
          discardfile ext_tab_dir:'discarded.txt'
          logfile ext_tab_dir:'importcsv.log'
          skip 1
          fields terminated by '|' lrtrim
          missing field values are null
          reject rows with all null fields
          (field1 char(2000),
          field2           char(2000),
          field3           char(2000))
          location ('test_xtable.csv'))
          reject limit unlimited;
The portion below the phrase "reject rows with all null fields" is what I meant by "field mapping", since I use it to match the csv structure. The order within the fields specification above the "organization external" can be rearranged any way I like, as long as the field name has a matching one in the "field mapping". Right now, I can only use char(2000) or varchar(2000) in the "field mapping" area, but not varchar2. Any ideas?

Error in Loading a clob via external table (Oracle 10.2.0.3 On Solaris 8)

Hi,
I am trying to insert a csv file as a single record as a CLOB (one row for entire csv file) and trying to do that via external table. But unalbe to do so. Following is the syntax I tried with:
create table testext_tab2
( file_data clob
organization external
     TYPE ORACLE_LOADER
     DEFAULT DIRECTORY dir_n1
access parameters
         RECORDS DELIMITED BY NEWLINE

             LOGFILE DIR_N1:'lob_tab_%a_%p.log'
             FIELDS TERMINATED BY ','
          MISSING FIELD VALUES ARE NULL
clob_filename CHAR(100)
COLUMN TRANSFORMS (file_data FROM LOBFILE (clob_filename) FROM (DIR_N1) CLOB)
LOCATION ('emp.txt')
REJECT LIMIT UNLIMITED
--it gives the output that the table is created but the table does not have any rows (select count(*) from testext_tab2 gives 0 rows)
-- and the logfile has entries like follows:

that LOB are not supported for external tables but there are other sites with examples of CLOB being loaded by external tables.

External tables in Oracle 11g database is not loading null value records

We have upgraded our DB from Oracle 9i to 11g...
It was noticed that data load to external tables in 9i is rejecting the records with null columns..However upgrading it to 11g,it allows the records with null values.
Is there are way to restrict loading the records that has few coulmns that are null..
Can you please share if this is the expected behaviour in Oracle 11g...
Thanks.

Data isn't really loaded to an External Table. Rather, the external table lets you query an external data source as if it were a regular database table. To not see the rows with the NULL value, simply filter those rows out with your SQL statement:
SELECT * FROM my_external_table WHERE colX IS NOT NULL;
HTH,
