Open Source Python/Oracle Utility - cx_Oracle

cx_Oracle is a Python extension module that allows access to Oracle and conforms to the Python database API 2.0 specifications with a number of additions. The method cursor.nextset() and the time data type are not supported by Oracle and are therefore not implemented.

See http://www.python.org/topics/database/DatabaseAPI-2.0.html for more information on the Python database API specification. See the included documentation for additional information.

For feedback or patches, contact Anthony Tuininga at anthony.tuininga@gmail.com. For help or to ask questions, please use the mailing list at http://lists.sourceforge.net/lists/listinfo/cx-oracle-users.

Please note that an Oracle client (or server) installation is required in order to use cx_Oracle. If you do not require the tools that come with a full client installation, it is recommended to install the Instant Client which is far easier to install.

Binary Install

Place the file cx_Oracle.pyd or cx_Oracle.so anywhere on your Python path.

Source Install

This module has been built with Oracle 9.2.0, 10.2.0, 11.1.0 on Linux, Solaris and Windows. Others have reported success with other platforms such as Mac OS X.

Use the provided setup.py to build and install the module which makes use of the distutils module. Note that on Windows, I have used mingw32 (http://www.mingw.org) and the module will not build with MSVC without modification. The commands required to build and install the module are as follows:

python setup.py build python setup.py install

See BUILD.txt for additional information.

Usage Example

import cx_Oracle

# connect via SQL*Net string or by each segment in a separate argument #connection = cx_Oracle.connect("user/password@TNS") connection = cx_Oracle.connect("user", "password", "TNS")

cursor = connection.cursor() cursor.execute("""

select Col1, Col2, Col3 from SomeTable where Col4 = :arg_1

and Col5 between :arg_2 and :arg_3""",

arg_1 = "VALUE", arg_2 = 5, arg_3 = 15)

for column_1, column_2, column_3 in cursor:
print "Values:", column_1, column_2, column_3

For more examples, please see the test suite in the test directory and the samples in the samples directory. You can also look at the scripts in the cx_OracleTools (http://cx-oracletools.sourceforge.net) and the modules in the cx_PyOracleLib (http://cx-pyoraclelib.sourceforge.net) projects.
