What is the method for utilizing the polars library in Python to read data from an MS sql server?

edit

To utilize the polars library in Python to read data from an MS SQL server, you can follow these steps:

1. Install the required packages by running the following command in your terminal:

pip install pyodbc pandas polars

1. Import the necessary libraries:

import polars as pl
import pandas as pd
import pyodbc

1. Set up a connection to the MS SQL server:

server = '<server_name>.<domain_name>.com'
database = '<database_name>'
username = '<username>'
password = '<password>'

connection_string = f'DRIVER={{ODBC Driver 17 for SQL Server}};' \
                    f'SERVER={server};DATABASE={database};UID={username};PWD={password};'
cnxn = pyodbc.connect(connection_string, autocommit=True)

1. Retrieve data from the MS SQL server into a Pandas DataFrame:

query = "SELECT * FROM <table_name>"
df = pd.read_sql(query, cnxn)

1. Convert the Pandas DataFrame to a Polars DataFrame:

pl_df = pl.from_pandas(df)

Now, you can use all the Polars DataFrame methods to manipulate and analyze the data from the MS SQL server.
