Btrieve ODBC Driver

The Pervasive SQL (Btrieve) ODBC Driver is a powerful tool that allows you to connect with Btrieve-based databases directly from any applications that support ODBC connectivity.

Access Btrieve databases from virtually anywhere through a standard ODBC Driver interface.



Connect to Btrieve as an ODBC data source in PyCharm using the CData ODBC Driver for Btrieve.

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 Btrieve 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 Btrieve 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 Btrieve

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 PSQL v13 client will need to be installed on the same machine as the driver. To connect, set the User, Password, Server, and Database properties.

Below is the syntax for a DSN:

[CData Btrieve Source] Driver = CData ODBC Driver for Btrieve Description = My Description User = myuser Password = mypassword Server = myserver Database = mydatabase

Execute SQL to Btrieve

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 Btrieve};User = myuser;Password = mypassword;Server = myserver;Database = mydatabase;') cursor = cnxn.cursor() cursor.execute("SELECT Student_ID, Transaction_Number FROM Billing WHERE Student_ID = '22'") rows = cursor.fetchall() for row in rows: print(row.Student_ID, row.Transaction_Number)

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