devart-snowflake-connector 1.3.0

New level of functionality and performance in data access via Python

Python Connector for Snowflake

Python Connector for Snowflake is a connectivity solution for accessing the Snowflake data cloud from Python applications. It fully implements the Python DB API 2.0 specification. The connector is distributed as a wheel package for Windows and Windows Server.

Connecting

To establish a connection to a Snowflake database, import the connector and use the connect() method with your connection parameters.

Import the connector

First, import the Snowflake connector module:

my_connection = snowflake.connect(
    Domain="your_instance;",    UserId="your_username",    Password="your_password",Database="your_database;"
)

Establish a connection

Call the connect() method and obtain a connection object.

response = snowflake.signin()
my_connection = snowflake.connect(
    CompanyId=response["Company Id"],
    RefreshToken=response["Refresh Token"]
)

Replace the example values with your actual connection values.

Querying data

Once connected, you can execute SQL queries to retrieve data from your Snowflake database.

Execute a query

Create a cursor object using the cursor() connection method.

my_cursor = my_connection.cursor()

Execute a SQL query using the execute() cursor method.

my_cursor.execute("SELECT * FROM employees")

Retrieve results using one of the fetch*() methods.

for row in my_cursor.fetchall(): 
    print(row)

Parameterized queries

You can use parameterized queries to pass variable values to your SQL statements. This allows you to reuse the same query with different data and helps to prevent SQL injection attacks.

Pass parameters as a list or tuple to the execute() method:

for row in my_cursor.fetchall(): 
    print(row)

Each placeholder ? in the query is replaced with a corresponding value from the parameter list.
