This tutorial uses the name pythondemo: python create_user.py Then open a terminal window and run create_user.py to execute the create_user.sql script and create the sample user.

If you need to create a new user for this tutorial, review the grants created in samples/tutorial/sql/create_user.sql by opening it in your favorite text editor. If you have an existing user, you may be able to use it for most examples (some examples may require extra permissions). The tutorial instructions may need adjusting, depending on how you have set up your environment. If you are using Oracle Autonomous Database (ADB), use the ADMIN user instead of SYSTEM. Substitute the admin values for your environment. Pw = getpass.getpass('Enter password for %s: ' % user) Pw = os.environ.get('PYTHON_SYSPASSWORD') User = os.environ.get('PYTHON_SYSUSER', 'SYSTEM')ĭsn = os.environ.get('PYTHON_SYS_CONNECT_STRING', 'localhost/orclpdb') Using environment variables is convenient because you will not be asked to re-enter the password when you run scripts: In Python Database API terminology, the connection string parameter is called the 'data source name', or 'dsn'. The default system connection string is for the ' orclpdb' database service on the same machine as Python. For example, the default username is ' SYSTEM' unless the environment variable ' PYTHON_SYSUSER' contains a different username.

Alternatively, you can set the given environment variables in your terminal window. This file is included in other Python files for creating and dropping the tutorial user.Įdit db_config_sys.py file and change the default values to match the system connection information for your environment. Review db_config_sys.py in the tutorial directory.

Review the privileged database credentials used for creating the schema.

The samples/tutorial/sql directory has all the SQL scripts used by the Python files to create database tables and other objects.

On Linux, use Python 3.6 orĪ command like pip install oracledb -upgradeĮnsure you can access an Oracle Database. Your operating system package library or from. Install Python 3 if not already available. The database can be on the same machine as Python, or it can be remote. Load the Oracle Client libraries via an application script runtime option are However, some additional features areĪvailable when python-oracledb uses them. This modeĭoes not need Oracle Client libraries. 'thin' mode, which connects directly to Oracle Database. Both modes have comprehensive functionality supporting the
