Using the CData ODBC Driver for SAP Business Warehouse 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 SAP Business Warehouse 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 SAP Business Warehouse 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 SAP Business Warehouse

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.

To connect to SAP Business Warehouse, set the URL property to a valid SAP Business Warehouse server base URL. The driver must connect to SAP Business Warehouse instances hosted over HTTP with XMLA access.

The driver supports the following authentication schemes via the AuthScheme property:

• None: Anonymous authentication, if available on the server.
• Basic: Set User and Password and set AuthScheme to Basic.
• Kerberos: See the Using Kerberos section of the help documentation for the required Kerberos properties.

By default, the driver attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

Below is the syntax for a DSN:

[CData SAPBusinessWarehouse Source]
Driver = CData ODBC Driver for SAP Business Warehouse
Description = My Description
URL = https://mysapserver:8000
AuthScheme = Basic
User = username
Password = password

Execute SQL to SAP Business Warehouse

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 SAPBusinessWarehouse};URL = https://mysapserver:8000;AuthScheme = Basic;User = username;Password = password;')
cursor = cnxn.cursor()
cursor.execute("SELECT CustomerCount, City FROM Sales WHERE Country = 'US'")
rows = cursor.fetchall()
for row in rows:
  print(row.CustomerCount, row.City)

After connecting to SAP Business Warehouse in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to SAP Business Warehouse data as if it were a standard database.
