```sql
SELECT *
FROM `tb_account`
LEFT JOIN `tb_article` AS `a` ON `tb_account`.`id` = `a`.`account_id`
LEFT JOIN `tb_article` AS `a`
ON `a`.`is_delete` = 0 and `tb_account`.`id` = `a`.`account_id`
WHERE `tb_account`.`age` >= 10
AND `tb_account`.`is_delete` = 0
AND `a`.`is_delete` = 0
```
自动添加上 `tb_account.is_delete = 0 AND a.is_delete = 0` 条件。
在 `left join on` 条件自动添加：`a.is_delete = 0`，并在 where 条件添加上 `tb_account.is_delete = 0`。
