+-- ==========================================
+-- 第一部分：DDL - 表结构修改
+-- ==========================================
+
+-- 1. 工序路线主表 (pro_route) 扩展
+-- 新增字段：制造类型（制造类型直接决定时间计算模式）
+ALTER TABLE `pro_route` 
+ADD COLUMN `manufacture_type` VARCHAR(20) DEFAULT 'DISCRETE' 
+    COMMENT '制造类型: DISCRETE=离散制造(顺序推进), CONTINUOUS=连续制造(同步开工)' 
+    AFTER `status`;
+
+-- 2. 工序路线明细表 (pro_route_process) 扩展
+-- 新增字段：转运时间（离散制造）和等待开始时间（连续制造）
+ALTER TABLE `pro_route_process` 
+ADD COLUMN `transfer_time` BIGINT DEFAULT 0 
+    COMMENT '转运时间（秒），离散制造时从上一工序到本工序的转运耗时' 
+    AFTER `duration`,
+ADD COLUMN `wait_start_time` BIGINT DEFAULT 0 
+    COMMENT '等待开始时间（秒），连续制造时从生产起始时间的延迟' 
+    AFTER `transfer_time`;
+
+-- ==========================================
+-- 第二部分：DML - 数据迁移
+-- ==========================================
+
+-- 3. 为现有工序路线设置默认值（离散制造）
+UPDATE `pro_route` 
+SET `manufacture_type` = 'DISCRETE' 
+WHERE `manufacture_type` IS NULL;
+
+-- 4. 为现有工序明细设置默认转运时间和等待开始时间为0
+UPDATE `pro_route_process` 
+SET `transfer_time` = 0,
+    `wait_start_time` = 0
+WHERE `transfer_time` IS NULL 
+   OR `wait_start_time` IS NULL;
+
+-- ==========================================
+-- 第三部分：数据验证查询
+-- ==========================================
+
+-- 5. 验证工序路线表新增字段
+SELECT 
+    COUNT(*) AS total_routes,
+    SUM(CASE WHEN manufacture_type = 'DISCRETE' THEN 1 ELSE 0 END) AS discrete_count,
+    SUM(CASE WHEN manufacture_type = 'CONTINUOUS' THEN 1 ELSE 0 END) AS continuous_count
+FROM `pro_route`;
+
+-- 6. 验证工序明细表新增字段
+SELECT 
+    COUNT(*) AS total_processes,
+    SUM(CASE WHEN transfer_time = 0 THEN 1 ELSE 0 END) AS zero_transfer_time,
+    SUM(CASE WHEN transfer_time > 0 THEN 1 ELSE 0 END) AS has_transfer_time,
+    SUM(CASE WHEN wait_start_time = 0 THEN 1 ELSE 0 END) AS zero_wait_time,
+    SUM(CASE WHEN wait_start_time > 0 THEN 1 ELSE 0 END) AS has_wait_time,
+    AVG(transfer_time) AS avg_transfer_time,
+    MAX(transfer_time) AS max_transfer_time,
+    AVG(wait_start_time) AS avg_wait_time,
+    MAX(wait_start_time) AS max_wait_time
+FROM `pro_route_process`;
+
+-- 7. 查看表结构变化（可选）
+-- SHOW FULL COLUMNS FROM `pro_route`;
+-- SHOW FULL COLUMNS FROM `pro_route_process`;
+
+-- ==========================================
+-- 第四部分：回滚脚本（如需要）
+-- ==========================================
+
+/*
+-- 警告：此部分仅用于回滚，会删除新增的字段和数据
+-- 请谨慎执行！
+
+-- 回滚工序路线主表
+ALTER TABLE `pro_route` 
+DROP COLUMN `manufacture_type`;
+
+-- 回滚工序明细表
+ALTER TABLE `pro_route_process` 
+DROP COLUMN `transfer_time`,
+DROP COLUMN `wait_start_time`;
+*/
+
+-- ==========================================
+-- 执行说明
+-- ==========================================
+-- 1. 建议在测试环境先执行验证
+-- 2. 生产环境执行前务必备份数据库
+-- 3. 分步执行，每步验证无误后再继续
+-- 4. 执行第三部分（验证查询）确认数据正确性
+-- 5. 如需回滚，使用第五部分的回滚脚本
