username = 'your_username'
password = 'your_password'
driver = '{ODBC Driver 17 for SQL Server}'

# Connect to Azure SQL Database
connection_string = f'DRIVER={driver};SERVER={server};DATABASE={database};UID={username};PWD={password}'
connection = pyodbc.connect(connection_string)

# Create a table for clinical data
create_table_query = '''
CREATE TABLE PatientData (
    PatientID INT PRIMARY KEY,
    Age INT,
    Diagnosis VARCHAR(100),
    Treatment VARCHAR(200)
);
'''

with connection.cursor() as cursor:
    cursor.execute(create_table_query)

# Insert sample patient data
insert_query = '''
INSERT INTO PatientData (PatientID, Age, Diagnosis, Treatment)
VALUES
    (1, 45, 'Diabetes', 'Insulin therapy'),
    (2, 38, 'Hypertension', 'ACE inhibitors');
'''

with connection.cursor() as cursor:

    query='SELECT * FROM PatientData',
    connection_string=connection_string
)
data = dataset.to_pandas_dataframe()

# Define the target column
target_column = 'LengthOfStay'

# Split the data into features and target
X = data.drop(columns=[target_column])
y = data[target_column]

# Create an experiment in Azure Machine Learning
experiment = Experiment(workspace=ws, name='hospital-stay-prediction')

# Configure the AutoML settings
