执行顺序：需按以下顺序执行建表语句，避免外键依赖报错：
t_industry_index → t_stock_basic → t_stock_daily_trade（及子表）→ t_stock_high_low_status
分表扩展：
MySQL：新增月份分区时，执行 ALTER TABLE t_stock_daily_trade ADD PARTITION (...)，示例：
ALTER TABLE t_stock_daily_trade ADD PARTITION (
PARTITION `p202504` VALUES LESS THAN (TO_DAYS('2025-05-01')) COMMENT '2025年4月数据'
);
