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

xBase 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 xBase 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 xBase 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.

xBase 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.

The DataSource property must be set to the name of the folder that contains the .dbf files. Specify the IncludeFiles property to work with xBase table files having extensions that differ from .dbf. Specify multiple extensions in a comma-separated list.

Below is the syntax for a DSN:

[CData xBase Source] Driver = CData ODBC Driver for xBase Description = My Description DataSource = MyDBFFilesFolder

xBase 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 xBase};DataSource = MyDBFFilesFolder;') cursor = cnxn.cursor() cursor.execute("SELECT Company, Total FROM Invoices WHERE Class = 'ASSET'") rows = cursor.fetchall() for row in rows: print(row.Company, row.Total)

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