python sql server code example

Example 1: python query mssql

import pyodbc
server = '<server>.database.windows.net'
database = '<database>'
username = '<username>'
password = '<password>'   
driver= '{ODBC Driver 17 for SQL Server}'

with pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1433;DATABASE='+database+';UID='+username+';PWD='+ password) as conn:
    with conn.cursor() as 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()

Example 2: connect to sql server with python

import pyodbc 
# Some other example server values are
# server = 'localhost\sqlexpress' # for a named instance
# server = 'myserver,port' # to specify an alternate port
server = 'tcp:myserver.database.windows.net' 
database = 'mydb' 
username = 'myusername' 
password = 'mypassword' 
cnxn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()

#Sample select query
cursor.execute("SELECT @@version;") 
row = cursor.fetchone() 
while row: 
    print(row[0])
    row = cursor.fetchone()

Example 3: pyodbc sql server connection string

conn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER=test;DATABASE=test;UID=user;PWD=password')
