-- RailwaySystem 数据库 V2 回滚脚本: 002_rollback_modified_tables.sql
|

-- 适用数据库: KingbaseES V009R003C018 (schema: public)
|
||
|
|
-- 执行目标: 严格基于 000_phase05_exact_schema.sql 结构与 bak_v1_* 数据还原 13 张表

|
-- 事务边界: 全程在显式事务 BEGIN ... COMMIT 中执行
|

|
-- 规范要求:
|
||
|
|
-- 1. 彻底摒弃 CTAS 丢失约束/默认值/触发器的不可靠方案
|
||
|
|
-- 2. 精确采用 Phase 0.5 原始 DDL 重建表结构
|

|
|
-- 3. 从 bak_v1_* 恢复真实数据并严格校验行数
