|
||
*/
|
||
|
||
-- ========================================
|
||
-- 清理备份表（确认数据无误后可执行）
|
||
-- ========================================
|

/*
|
||
DROP TABLE IF EXISTS psy_user_profile_backup_numeric_names;
|
||
DROP TABLE IF EXISTS sys_user_backup_numeric_names;
|

*/
|
||
|
||
-- ========================================
|
||
-- 执行说明
|
||
-- ========================================
|
||
|
||
/*
|
||
执行顺序：
|
||
1. 先执行"第一步"的查询，确认是否是要删除的数据（检查姓名字段）
|
||
2. 执行"第二步"创建备份（必须！）
|
||
3. 验证备份数据
|
||
4. 执行"第三步"删除关联数据（一条一条执行，观察影响行数）
|
||
5. 执行"第四步"删除主表数据
|
||
6. 执行"第五步"验证删除结果
|
||
7. 如果出错，使用恢复脚本回滚
|
||
|
||
重要发现：
|
||
- user_name 字段在 sys_user 表中，不在 psy_user_profile 表中
|
||
- 需要通过 INNER JOIN 关联两个表进行查询
|
||
- psy_user_profile.user_id = sys_user.user_id
|
||
|
||
注意事项：
|
||
1. 务必在测试环境先执行一遍
|
||
2. 生产环境执行前做完整数据库备份
|
||
3. 建议在业务低峰期执行
|
||
4. 执行前通知相关人员
|
||
5. 保留备份表至少7天
|
||
6. 正则表达式 '^[0-9]+$' 匹配纯数字（只包含0-9的字符串）
|
||
7. 如果有其他关联表，需要补充删除语句
|
||
|
||
判断规则：
|
||
- '^[0-9]+$' 表示从开头到结尾都是数字
|
||
- 例如：'123'、'456' 会被匹配
|
||
- 例如：'张三'、'123abc'、'李4' 不会被匹配

-- 方案A：只删除纯数字且长度在特定范围的姓名
