+-- 修复 task_item 表缺少 group_no 字段的问题
+-- 问题：插入task_item时报错 Unknown column 'group_no' in 'field list'
+-- 解决：添加 group_no 字段用于流水线任务分组
+-- 日期：2026-01-02
+
+USE designhub;
+
+-- 添加 group_no 字段
+ALTER TABLE `task_item` 
+ADD COLUMN `group_no` INT DEFAULT 1 
+COMMENT '任务组编号（用于流水线分组）' 
+AFTER `item_no`;
+
+-- 验证修改结果
+SELECT 
+    COLUMN_NAME, 
+    COLUMN_TYPE, 
+    IS_NULLABLE,
+    COLUMN_DEFAULT, 
+    COLUMN_COMMENT
+FROM 
+    INFORMATION_SCHEMA.COLUMNS
+WHERE 
+    TABLE_SCHEMA = 'designhub'
+    AND TABLE_NAME = 'task_item'

+
+-- 说明：
+-- group_no 用于流水线任务的分组管理
+-- 当流水线任务中的子任务需要按接单部门分组时使用
+-- 同一个 group_no 的子任务属于同一个执行组
+-- 默认值为 1，表示所有子任务在同一组
