计算缺少的列id的列表

import pymysql

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

# 执行查询操作
cursor.execute("SELECT id, column1, column2 FROM table")

# 初始化缺少列id的列表
missing_ids = []

# 遍历每一行数据
for row in cursor.fetchall():
    id = row[0]
    column1 = row[1]
    column2 = row[2]

    # 检查是否缺少特定列的值
    if column1 is None or column1 == '' or column2 is None or column2 == '':
        missing_ids.append(id)

# 关闭数据库连接
cursor.close()
conn.close()

# 返回缺少列id的列表
print(missing_ids)
