## 数据删除任务
|
||
|
||
- 用户数据范围暨**用户id集**：wa_users表中的用户id集
|
||
- 查询wa_withdraw表中用户id不在用户数据范围内的记录，并写一个删除这些数据的sql
|
||
|
||
### 1) 查询核对 SQL
|
||
|
||
```sql
|
||
-- 统计孤立提现记录数
|
||
SELECT COUNT(*) AS orphan_cnt
|
||
FROM wa_withdraw w
|
||
WHERE NOT EXISTS (
|
||
SELECT 1 FROM wa_users u WHERE u.id = w.user_id
|
||
);
|
||
|
||
-- 抽样查看前 100 条，核对是否确实需要清理
|
||
SELECT w.*
|
||
FROM wa_withdraw w
|
||
WHERE NOT EXISTS (
|
||
SELECT 1 FROM wa_users u WHERE u.id = w.user_id
|
||
)
|
||
ORDER BY w.id
|
||
LIMIT 100;
|
||
```
|
||
|
||
### 2) 删除 SQL
|
||
|
||
```sql
|
||
DELETE w FROM wa_withdraw w
|
||
WHERE NOT EXISTS (
|
||
SELECT 1 FROM wa_users u WHERE u.id = w.user_id
|
||
);
|
||
```
|
||
|
||
### 3) 操作备注
|
||
|
||
- 建议在执行前对 wa_withdraw 做一次备份：`CREATE TABLE wa_withdraw_bak_20260423 AS SELECT * FROM wa_withdraw;`
|
||
- 建议先跑 `COUNT(*)` 与 `LIMIT 100` 人工核对，再执行 `DELETE`
|
||
- 全程放入事务中执行，确认无误后再 `COMMIT`
