Connect to Azure SQL Database using Python and Jupyter Notebook

In this tutorial, you will learn how to use Python and Jupyter Notebooks to connect to an Azure SQL Database. To complete the exercise, you will need to install:

  • Python 3 (make sure to add Python to your PATH) and
  • Visual Studio Code.

Set up pyodbc Python development environment

In this exercise, you will use the pyodbc library to connect to your Azure SQL database and execute SQL queries.

  1. Install the Microsoft ODBC Driver for SQL Server on Windows.
  2. Open the command prompt and run the following command to install the pyodbc library.
pip install pyodbc

Set up Jupyter Notebooks development environment

  1. Open the command prompt and run the following command to install the Jupyter Notebook.
pip install jupyter
  1. Then, open Visual Studio Code. Go to View > Extensions and search for Jupyter.
  2. Install the Jupyter Extension for Visual Studio Code.

Get connection information

The next step is to collect the information that you need to connect to the Azure SQL Database. You need the server name, the database name, and the login credentials (username and password).

  1. Sign in to Azure Portal, expand the left navigation panel and select All resources.
    Select All resources in Azure
  2. Select the SQL Database that you have created in the part 1.
  3. In the Overview tab, you can see the fully qualified server name.
    Server name - Azure portal

Create Connection

Open Visual Studio Code and create a new Jupyter file named connect-sql.ipynb. In the first cell, add the following code to connect to your sql database using Python:

import pyodbc

# Establish the connection
server = '<server>.database.windows.net'
database = '<database>'
username = '<username>'
password = '<password>'
driver= '{ODBC Driver 17 for SQL Server}'
conn = pyodbc.connect('DRIVER=' + driver + ';SERVER=' +
    server + ';PORT=1433;DATABASE=' + database +
    ';UID=' + username + ';PWD=' + password)

print(conn)
conn.close()

where:

  • server is the server name,
  • database refers to the name of the database that you created in part 1,
  • username is the admin login name, and
  • password is the password of the admin.
