| """把第二轮 DeepSeek 出的 6 个大库和 2025 道题并进来（cn-sqlite-round2.zip，照 deepseek_tasks.md 做的）。 |
| |
| python scripts/import_round2.py --src <解压出来的 cn-sqlite-full 目录> |
| |
| zip 是在旧版项目上做的，只取两样：schemas/hard2/*.sql 和 data/hard2_train.jsonl。 |
| - property_mgmt、car_service 的主键是复数（communities_id），引用它的外键却是单数（community_id）， |
| car_service 里还同时有 lead_technician_id 和 lead_technicians_id。统一改成单数，建表语句和 SQL 一起改 |
| - 改名前后结果必须一模一样：同一份数据建两个库，一个 ALTER TABLE RENAME COLUMN，老 SQL 跑老库、新 SQL 跑新库，逐条比 |
| - 题目写到 data/round2/raw/<库名>.jsonl（db / question / sql / difficulty / type），还没筛， |
| 不进训练；check_round2.py 筛完才写到 data/new/ |
