To use cx_Oracle 7 with Python and Oracle Database you need: • Python 2.7 or 3.5 and higher. Older versions of cx_Oracle may work with older versions of Python. • Oracle client libraries.

These can be from the free, or those included in Oracle Database if Python is on the same machine as the database. Oracle client libraries versions 18, 12, and 11.2 are supported on Linux, Windows and macOS. Users have also reported success with other platforms. • An Oracle Database. Oracle’s standard client-server version interoperability allows cx_Oracle to connect to both older and newer databases.

• If your database is on a remote computer, then download and unzip the client libraries from the free “Basic” or “Basic Light” package for your operating system architecture. Instant Client on Windows requires an appropriate. On Linux, the libaio (sometimes called libaio1) package is needed. • Alternatively use the client libraries already available in a locally installed database such as the free release. Version 18 and 12.2 client libraries can connect to Oracle Database 11.2 or greater. Version 12.1 client libraries can connect to Oracle Database 10.2 or greater. Version 11.2 client libraries can connect to Oracle Database 9.2 or greater.

The database abstraction layer in cx_Oracle is, which means that the can be useful to review. • Create a script like the one below. # myscript.py from __future__ import print_function import cx_Oracle # Connect as user 'hr' with password 'welcome' to the 'oraclepdb' service running on this computer. Connection = cx_Oracle. Connect ( 'hr', 'welcome', 'localhost/orclpdb' ) cursor = connection. Cursor () cursor. Execute ( '' SELECT first_name, last_name FROM employees WHERE department_id =:did AND employee_id >:eid'', did = 50, eid = 190 ) for fname, lname in cursor: print ( 'Values:', fname, lname ) Locate your Oracle Database username and password, and the database connection string.

The connection string is commonly of the format hostname/servicename, using the hostname where the database is running, and the service name of the Oracle Database instance. Substitute your username, password and connection string in the code. Run the Python script, for example.

Cx_Oracle requires Oracle Client libraries. The libraries provide the necessary network connectivity to access an Oracle Database instance. They also provide basic and advanced connection management and data features to cx_Oracle. The simplest way to get Oracle Client libraries is to install the free “Basic” or “Basic Light” package.

The libraries are also available in any Oracle Database installation or full Oracle Client installation. Oracle’s standard client-server network interoperability allows connections between different versions of Oracle Client libraries and Oracle Database. Rhino husbandry manual. For certified configurations see Oracle Support’s. In summary, Oracle Client 18 and 12.2 can connect to Oracle Database 11.2 or greater. Oracle Client 12.1 can connect to Oracle Database 10.2 or greater.
