如何获取当月生日的学生名单？

import datetime
import pymysql

# 连接数据库
conn = pymysql.connect(host='localhost', user='username', password='password', database='database_name')
cursor = conn.cursor()

# 获取当前月份
current_month = datetime.datetime.now().month

# 查询当月生日的学生名单
sql = "SELECT name FROM students WHERE MONTH(birthday) = %s"
cursor.execute(sql, (current_month,))
results = cursor.fetchall()

# 关闭数据库连接
cursor.close()
conn.close()

# 打印结果
for row in results:
    print(row[0])
