Using the CData ODBC Driver for LINE 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 LINE 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 LINE 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 LINE

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.

Start by setting the Profile connection property to the location of the LINE Profile on disk (e.g. C:\profiles\LINE.apip). Next, set the ProfileSettings connection property to the connection string for LINE (see below).

LINE API Profile Settings

The LINE Messaging API uses Channel Access Token authentication. To obtain a Channel Access Token:

1. Log in to the LINE Developers Console at https://developers.line.biz
2. Select your provider and open your Messaging API channel.
3. Navigate to the Messaging API tab.
4. Under Channel access token, click Issue to generate a long-lived token.
5. Copy the generated token.

After obtaining your Channel Access Token, set the following connection properties:

• AuthScheme: Set this to APIKey.

Set the following in the ProfileSettings connection property:

• APIKey: Set this to your LINE Channel Access Token.

Below is the syntax for a DSN:

[CData API Source]
Driver = CData ODBC Driver for LINE
Description = My Description
Profile = C:\profiles\LINE.apip
ProfileSettings = 'APIKey = your_channel_access_token
'
AuthScheme = APIKey

Execute SQL to LINE

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 API};Profile = C:\profiles\LINE.apip;ProfileSettings = 'APIKey = your_channel_access_token;';AuthScheme = APIKey;')
cursor = cnxn.cursor()
cursor.execute("SELECT DeliveryDate, DeliveredCount FROM ReplyMessageDelivery WHERE DeliveryDate = '20240115'")
rows = cursor.fetchall()
for row in rows:
  print(row.DeliveryDate, row.DeliveredCount)

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