PyCharm でCData ODBC Driver for SAP を使ってみた

SAP にODBC データソースとしてPyCharm から連携。

CData ODBC Drivers は、ODBC をサポートするあらゆる環境から利用可能です。 本記事では、PyCharm からのCData ODBC Driver for SAP の利用を説明します。ODBC Deriver をデータソースとして設定する方法、データソースをクエリするPyCharm のベーシックな方法を含みます。

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

Pyodbc をプロジェクトに追加

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.

SAP への接続

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

SAP へのクエリの実行

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 support@cdata.com.
