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 time data type is not supported by Oracle and is therefore not implemented. The method cursor.nextset() is not implemented either as the DB API specification assumes an implementation of cursors that does not fit well with Oracle's implementation of cursors and implicit results. See the method cursor.getimplicitresults() for more information.
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 firstname.lastname@example.org. 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.
Place the file cx_Oracle.pyd or cx_Oracle.so anywhere on your Python path.
This module has been built with Oracle 10g, 11g and 12c on Linux and Windows. Others have reported success with other platforms such as Mac OS X.
For simplified installation use pip
pip install cx_Oracle
Otherwise, you can use the provided setup.py to build and install the module
python setup.py build python setup.py install
See BUILD.txt for additional information.
# 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_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:
- 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.
