Connecting to Snowflake with Nuvolos Connector

1. Using SQLAlchemy with Username/Password

from nuvolos import get_connection
from sqlalchemy import text

# Connect using username and password
conn = get_connection(
    username="your_username",
    password="your_password",
    dbname="YOUR_DB",
    schemaname="YOUR_SCHEMA"
)

try:
    # Execute a query
    result = conn.execute(text("SELECT * FROM YOUR_TABLE"))
    for row in result:
        print(row)
finally:
    conn.close()

2. Using SQLAlchemy with RSA Key

import os
from nuvolos import get_connection
from sqlalchemy import text

# Set environment variables for RSA authentication
os.environ["SNOWFLAKE_RSA_KEY"] = "/path/to/rsa_key.p8"
os.environ["SNOWFLAKE_RSA_KEY_PASSPHRASE"] = "your_key_passphrase"  # Optional

# Connect using RSA key authentication
conn = get_connection(
    username="YOUR_USERNAME",
    dbname="YOUR_DB",
    schemaname="YOUR_SCHEMA"
)

try:
    # Execute a query
    result = conn.execute(text("SELECT * FROM YOUR_TABLE"))
    for row in result:
        print(row)
finally:
    conn.close()

3. Using Raw Connector with Username/Password

from nuvolos import get_raw_connection

# Connect using username and password
conn = get_raw_connection(
    username="your_username",
    password="your_password",
    dbname="YOUR_DB",
    schemaname="YOUR_SCHEMA"
)

4. Using Raw Connector with RSA Key

import os
from nuvolos import get_raw_connection

# Set environment variables for RSA authentication
os.environ["SNOWFLAKE_RSA_KEY"] = "/path/to/rsa_key.p8"
os.environ["SNOWFLAKE_RSA_KEY_PASSPHRASE"] = "your_key_passphrase"  # Optional

# Connect using RSA key authentication
conn = get_raw_connection(
    username="YOUR_USERNAME",
    dbname="YOUR_DB",
    schemaname="YOUR_SCHEMA"
)
