正確なPyodbc文字列のパススルーは私にとってはうまくいきます:
from sqlalchemy import create_engine
from sqlalchemy.engine import URL
connection_string = (
r"Driver=ODBC Driver 17 for SQL Server;"
r"Server=(local)\SQLEXPRESS;"
r"Database=myDb;"
r"Trusted_Connection=yes;"
)
connection_url = URL.create(
"mssql+pyodbc",
query={"odbc_connect": connection_string}
)
engine = create_engine(connection_url)
cnxn = engine.connect()
rows = cnxn.execute("SELECT name FROM sys.tables").fetchall()
print(rows)
