What is 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. Where do I get it? http://cx-oracle.sourceforge.net What's new? 1) Added support for LONG_UNICODE which is a type used to handle long unicode strings. These are not explicitly supported in Oracle but can be used to bind to NCLOB, for example, without getting the error "unimplemented or unreasonable conversion requested". 2) Set the row number in a cursor when executing PL/SQL blocks as requested by Robert Ritchie. 3) Added support for setting the module, action and client_info attributes during connection so that logon triggers will see the supplied values, as requested by Rodney Barnett. In addition, binaries are now being built for Python 3.3.
