如何通过MDB查询更新BegAtt & EndAtt的值？

import pyodbc

# 连接到MDB数据库
conn = pyodbc.connect(r'Driver={Microsoft Access Driver (*.mdb)};DBQ=path_to_your_mdb_file')

# 创建游标
cursor = conn.cursor()

# 查询BegAtt和EndAtt的值
select_query = "SELECT BegAtt, EndAtt FROM table_name"

# 执行查询
cursor.execute(select_query)

# 获取查询结果
result = cursor.fetchall()

# 更新BegAtt和EndAtt的值
update_query = "UPDATE table_name SET BegAtt = new_begatt_value, EndAtt = new_endatt_value WHERE condition"

# 执行更新
cursor.execute(update_query)

# 提交更改
conn.commit()
