Quickstart: Use Python to query an Azure SQL database

This article demonstrates how to use Python to connect to an Azure SQL database and use Transact-SQL statements to query data. For further SDK details, check out our reference documentation, the pyodbc GitHub repository, and a pyodbc sample.


To complete this quickstart, make sure you have the following:

Get SQL server connection information

Get the connection information you need to connect to the Azure SQL database. You'll need the fully qualified server name or host name, database name, and login information for the upcoming procedures.

  1. Sign in to the Azure portal.

  2. Go to the SQL databases or SQL managed instances page.

  3. On the Overview page, review the fully qualified server name next to Server name for a single database or the fully qualified server name next to Host for a managed instance. To copy the server name or host name, hover over it and select the Copy icon.

Create code to query your SQL database

  1. In a text editor, create a new file named sqltest.py.

  2. Add the following code. Substitute your own values for <server>, <database>, <username>, and <password>.


    The code in this example uses the sample AdventureWorksLT data, which you can choose as source when creating your database. If your database has different data, use tables from your own database in the SELECT query.

    import pyodbc
    server = '<server>.database.windows.net'
    database = '<database>'
    username = '<username>'
    password = '<password>'
    driver= '{ODBC Driver 17 for SQL Server}'
    cnxn = pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1433;DATABASE='+database+';UID='+username+';PWD='+ password)
    cursor = cnxn.cursor()
    cursor.execute("SELECT TOP 20 pc.Name as CategoryName, p.name as ProductName FROM [SalesLT].[ProductCategory] pc JOIN [SalesLT].[Product] p ON pc.productcategoryid = p.productcategoryid")
    row = cursor.fetchone()
    while row:
        print (str(row[0]) + " " + str(row[1]))
        row = cursor.fetchone()

Run the code

  1. At a command prompt, run the following command:

    python sqltest.py
  2. Verify that the top 20 Category/Product rows are returned, then close the command window.
