Pyodbc.connect () works, but not sqlalchemy.create_engine (). connect ()

Question

I am trying to write a Python script that can take Excel worksheets and import them into my SQL Server Express database (with Windows Authentication) as tables. For this, I use pandasExcel to read files in pandas DataFrame, so I hope to use pandas.to_sql()to import data into my database. However, to use this feature I need to use sqlalchemy.create_engine().

I can only connect to my database using pyodbcand run test queries. This output is done using followng code:

def create_connection(server_name, database_name):
    config = dict(server=server_name, database= database_name)

    conn_str = ('SERVER={server};DATABASE={database};TRUSTED_CONNECTION=yes')

    return pyodbc.connect(r'DRIVER={ODBC Driver 13 for SQL Server};' + conn_str.format(**config))

...

server = '<MY_SERVER_NAME>\SQLEXPRESS'
db = '<MY_DATABASE_NAME>

connection = create_connection(server, db)
cursor = connection.cursor()
cursor.execute('CREATE VIEW test_view AS SELECT * FROM existing_table')
cursor.commit()

, pandas.to_sql() - sqlalchemy.create_engine(), , create_connection() , .

:

engine = create_engine("mssql+pyodbc://@C<MY_SERVER_NAME>\SQLEXPRESS/<MY_DATABASE_NAME>?driver={ODBC Driver 13 for SQL Server}?trusted_connection=yes")
conn = engine.connect().connection

engine = create_engine("mssql+pyodbc://@C<MY_SERVER_NAME>\SQLEXPRESS/<MY_DATABASE_NAME>?trusted_connection=yes")   
conn = engine.connect().connection

A Pyodbc Python 3.6 Windows:

from sqlalchemy import create_engine
import urllib
conn_str = (
    r'Driver=ODBC Driver 11 for SQL Server;'
    r'Server=(local)\SQLEXPRESS;'
    r'Database=myDb;'
    r'Trusted_Connection=yes;'
)
quoted_conn_str = urllib.parse.quote_plus(conn_str)
engine = create_engine('mssql+pyodbc:///?odbc_connect={}'.format(quoted_conn_str))
cnxn = engine.connect()
rows = cnxn.execute("SELECT name FROM sys.tables").fetchall()
print(rows)
