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

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 8.1.7, 9.2.0 and 10.1.0 on Linux, Solaris, HP/UX, Tru64 Unix and Windows. It will likely build on other platforms and other Oracle versions but I haven't tried them. 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
# 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.arraysize = 50 cursor.execute("""
select Col1, Col2, Col3 from SomeTable where Col4 = :arg_1and 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.fetchall():
- print "Values:", column_1, column_2, column_3
EXCEPTIONS: The only exception to the DB API specification is the lack of a nextset() method which is not supported by Oracle.
