Using the CData ODBC Driver for OpenWeatherMap 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 OpenWeatherMap 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 OpenWeatherMap 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 OpenWeatherMap

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.

Using API Key Authentication

To obtain an API key, sign up for a free account at https://openweathermap.org/api and navigate to the API keys section of your dashboard. Copy your API key for use in the connection configuration.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your OpenWeatherMap API key.

Below is the syntax for a DSN:

[CData API Source]
Driver = CData ODBC Driver for OpenWeatherMap
Description = My Description
Profile = C:\path\to\OpenWeatherMap.apip
AuthScheme = APIKey
ProfileSettings = "APIKey = your_openweathermap_api_key"

Execute SQL to OpenWeatherMap

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:\path\to\OpenWeatherMap.apip;AuthScheme = APIKey;ProfileSettings = "APIKey = your_openweathermap_api_key";')
cursor = cnxn.cursor()
cursor.execute("SELECT ,  FROM AccumulatedPrecipitation WHERE Latitude = '40.7128'")
rows = cursor.fetchall()
for row in rows:
  print(row., row.)

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