如何使用mysql-connector检索日期时间值？

import mysql.connector

# 建立与MySQL数据库的连接
cnx = mysql.connector.connect(user='username', password='password',
                              host='hostname', database='database_name')

# 创建游标对象
cursor = cnx.cursor()

# 编写SQL查询语句
query = "SELECT * FROM table_name WHERE date_column = %s"

# 执行查询
date_value = '2022-01-01'
cursor.execute(query, (date_value,))

# 获取查询结果
result = cursor.fetchall()

# 打印查询结果
for row in result:
    print(row)

# 关闭游标和数据库连接
cursor.close()
cnx.close()
