pyodbc 访问 ms sqlserver

import pyodbc
import traceback
import config_json
import logging
class Server():
    def __init__(self):
        SERVER = '10.0.100.100'
        USERNAME = 'ma'
        PASSWORD = '123456'
        DATABASE = 'caiji'
        # self.connectionString = f'DRIVER={{ODBC Driver 18 for SQL Server}};SERVER={SERVER};DATABASE={DATABASE};ENCRYPT=yes;TrustServerCertificate=yes;UID={USERNAME};PWD={PASSWORD}'
        self.connectionString = 'DRIVER=ODBC Driver 18 for SQL Server;SERVER=%s;DATABASE=%s;ENCRYPT=yes;TrustServerCertificate=yes;UID=%s;PWD=%s' %(SERVER,DATABASE,USERNAME,PASSWORD)
    def updateDb(self):
        conn = pyodbc.connect(self.connectionString)
        cursor = self.conn.cursor()
        cmds=codecs.open("caiji.sql","r",'utf-8').read().split(";")
        for cmd  in cmds:
            print(cmd)
            cursor.execute(cmd)
        conn.commit()
        cursor.close()
        conn.close()

先使用的pymssql,没成功.
