PyCharm でCData ODBC Driver for Epicor ERP を使ってみた

Epicor ERP 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 Epicor ERP 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 Epicor ERP 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.

Epicor ERP 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.

To successfully connect to your ERP instance, you must specify the following connection properties:

  • Url:the URL of the server hosting your ERP instance. For example, https://myserver.EpicorSaaS.com
  • ERPInstance: the name of your ERP instance.
  • User: the username of your account.
  • Password: the password of your account.
  • Service: the service you want to retrieve data from. For example, BaqSvc.

In addition, you may also set the optional connection properties:

  • ApiKey: An optional key that may be required for connection to some services depending on your account configuration.
  • ApiVersion: Defaults to v1. May be set to v2 to use the newer Epicor API.
  • Company: Required if you set the ApiVersion to v2.

Below is the syntax for a DSN:

[CData EpicorERP Source] Driver = CData ODBC Driver for Epicor ERP Description = My Description Service = Erp.BO.CustomerSvc ERPInstance = MyInstance URL = https://myaccount.epicorsaas.com User = username Password = password

Epicor ERP 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 EpicorERP};Service = Erp.BO.CustomerSvc;ERPInstance = MyInstance;URL = https://myaccount.epicorsaas.com;User = username;Password = password;') cursor = cnxn.cursor() cursor.execute("SELECT CustNum, Company FROM Customers WHERE CompanyName = 'CompanyName'") rows = cursor.fetchall() for row in rows: print(row.CustNum, row.Company)

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