Using the CData ODBC Driver for Oracle SCM in PyCharm

The CData ODBC Drivers can be used in any environment that supports loading an ODBC Driver. In this tutorial we will explore using the CData ODBC Driver for Oracle SCM from within PyCharm. Included are steps for adding the CData ODBC Driver as a data source, as well as basic PyCharm code to query the data source and display results.

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for Oracle SCM as well as PyCharm.

Add Pyodbc to the Project

Follow the steps below to add the pyodbc module to your project.

1. Click File -> Settings to open the project settings window.
2. Click Project Interpreter from the Project: YourProjectName menu.
3. To add pyodbc, click the + button and enter pyodbc.
4. Click Install Package to install pyodbc.

Connect to Oracle SCM

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

The following connection properties are required to connect to Oracle SCM data.

• Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
• User: The username of your Oracle Cloud service account.
• Password: The password of your Oracle Cloud service account.

Below is the syntax for a DSN:

[CData OracleSCM Source]
Driver = CData ODBC Driver for Oracle SCM
Description = My Description
Url = https://myinstance.oraclecloud.com
User = user
Password = password

Execute SQL to Oracle SCM

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc

cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for OracleSCM};Url = https://myinstance.oraclecloud.com;User = user;Password = password;')
cursor = cnxn.cursor()
cursor.execute("SELECT CarrierId, CarrierName FROM Carriers WHERE ActiveFlag = 'false'")
rows = cursor.fetchall()
for row in rows:
 print(row.CarrierId, row.CarrierName)

After connecting to Oracle SCM in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to Oracle SCM data as if it were a standard database. If you have any questions, comments, or feedback regarding this tutorial, please contact us at [email protected].
