库侧改造

可行：按原汇总层级重写为 ROLLUP 或显式 GROUPING SETS

应用侧改造

可行：消费方若依赖小计行位置或 NULL 标记，需同步调整识别逻辑

推荐路线：db_side。验证建议：对照明细、小计、总计行数和值，并覆盖真实 NULL、GROUPING、HAVING 和显式 ORDER BY

SELECT zone, state, COUNT(*) FROM master_data GROUP BY zone, state WITH ROLLUP

SELECT year, country, SUM(profit) FROM sales GROUP BY year, country WITH ROLLUP HAVING SUM(profit) > 0

SELECT zone, state, COUNT(*) FROM master_data GROUP BY ROLLUP(zone, state)
