We can use External table to extract data from data base
to .csv file. External table of TYPE ORACLE_DATAPUMP will
do.

Syntax is:
CREATE TABLE <ext_table_name>
ORGANISED EXTERNALLY
(
TYPE ORACLE_DATAPUMP
DEFAULT DIRECTORY <directory_name>
LOCATION <filename.dat>
)
AS SELECT * FROM <internal_table_name>

Answer / kiran penujuri

We have one very good oracle utility called EXPORT
Exporting of ORACLE database objects is controlled by
parameters.
To get familiar with EXPORT parameters type:
exp help=y
You will get a short description and the default settings
will be shown.
The EXPORT utility may be used in three ways:

Interactive dialogue
Simply type exp. You will be prompted for your ORACLE
userid, password. All other prompts answer by pressing the
return key. This is the easiest way to export all data you
stored in the ORALE database. You may assign other values
than the defaults to the parameters but in most cases it is
unnecessary.
Controlled through bypassed parameters
You may bypass parameters when you export data from the
database. Type:
exp <userid/password>
<parameter>=<value>,<parameter>=<value>,...
Example of exporting scott's tables EMP and DEPT to file
empdept.expdat and storing all messages to file empdept.log:
exp scott/tiger file=empdept.expdat tables=(EMP,DEPT)
log=empdept.log

Parameterfile controlled
Instead of typing the parameters on the commandline you may
use a parameter file where the parameters are stored. The
syntax for this method is: exp <userid/password>
parfile=<filename>
Do not ignore warnings and messages! Look at your logfile
and repeat EXPORT until you get messages like:
About to export specified tables ...
. exporting table EMP 14
rows exported
. exporting table DEPT 4
rows exported
Export terminated successfully without warnings.

Hi,
In oracle,We have SQL loader utility tool. You can use that
utility with out creating index and referencial constraint.
thereafter you can see 18 million records are loaded within
a hour into database.

Thank you
