如何按年、月动态取回上一年(下个月)到当月底的所有数据

import datetime
import mysql.connector

# 获取当前年份和月份
current_year = datetime.datetime.now().year
current_month = datetime.datetime.now().month

# 计算上一年和下个月的年份和月份
last_year = current_year - 1
next_month = current_month + 1

# 连接到MySQL数据库
cnx = mysql.connector.connect(user='your_username', password='your_password',
                              host='your_host', database='your_database')
cursor = cnx.cursor()

# 构建查询语句
query = "SELECT * FROM your_table WHERE date_column >= %s AND date_column <= %s"
start_date = datetime.date(last_year, current_month, 1)
end_date = datetime.date(current_year, next_month, 1) - datetime.timedelta(days=1)
params = (start_date, end_date)

# 执行查询
cursor.execute(query, params)

# 获取查询结果
results = cursor.fetchall()

# 关闭数据库连接
cursor.close()
cnx.close()

# 处理查询结果
for row in results:
    # 进行业务逻辑处理或展示
    print(row)
