Using the CData ODBC Driver for SAP 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 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 as well as PyCharm.

Getting Started

---

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

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.

You can connect to SAP systems using either librfc32.dll, librfc32u.dll, NetWeaver, or Web Services (SOAP). Set the ConnectionType connection property to CLASSIC (librfc32.dll), CLASSIC_UNICODE (librfc32u.dll), NETWEAVER, or SOAP.

If you are using the SOAP interface, set the Client, RFCUrl, SystemNumber, User, and Password properties, under the Authentication section.

Otherwise, set Host, User, Password, Client, and SystemNumber.

Note: We do not distribute the librfc32.dll or other SAP assemblies. You must find them from your SAP installation and install them on your machine.

For more information, see this guide on obtaining the connection properties needed to connect to any SAP system.

Below is the syntax for a DSN:

[CData SAPERP Source]
Driver = CData ODBC Driver for SAP
Description = My Description
Host = sap.mydomain.com
User = EXT90033
Password = xxx
Client = 800
System Number = 09
ConnectionType = Classic
Location = C:/mysapschemafolder

Execute SQL to SAP

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 SAPERP};Host = sap.mydomain.com;User = EXT90033;Password = xxx;Client = 800;System Number = 09;ConnectionType = Classic;Location = C:/mysapschemafolder;')
cursor = cnxn.cursor()
cursor.execute("SELECT MANDT, MBRSH FROM MARA WHERE ERNAM = 'BEHRMANN'")
rows = cursor.fetchall()
for row in rows:
 print(row.MANDT, row.MBRSH)

After connecting to SAP in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to SAP 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].
