+-- =============================================
+-- 保养计划优化 - 频率改为计划执行时间
+-- 作者: Cascade
+-- 日期: 2026-01-20
+-- 描述: 
+--   1. 添加计划执行时间字段(planned_time)替代频率
+--   2. 修改状态字段含义：0待执行/1已执行/2已取消
+--   3. 执行一次计划就结束，不再循环
+-- =============================================
+
+-- =============================================
+-- 一、扩展表结构
+-- =============================================
+
+SET @dbname = DATABASE();
+SET @tablename = 'dm_inspection_plan';
+
+-- 1.1 添加 planned_time 字段（计划执行时间）
+SET @columnname = 'planned_time';
+SET @preparedStatement = (SELECT IF(
+  (SELECT COUNT(*) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = @dbname AND TABLE_NAME = @tablename AND COLUMN_NAME = @columnname) > 0,
+  'SELECT 1',
+  CONCAT('ALTER TABLE ', @tablename, ' ADD COLUMN ', @columnname, ' DATETIME DEFAULT NULL COMMENT ''计划执行时间'' AFTER `end_date`')
+));
+PREPARE alterIfNotExists FROM @preparedStatement;
+EXECUTE alterIfNotExists;
+DEALLOCATE PREPARE alterIfNotExists;
+
+-- =============================================
+-- 二、更新字典数据
+-- =============================================
+
+-- 2.1 新增保养计划状态字典类型
+INSERT IGNORE INTO `sys_dict_type` (`dict_name`, `dict_type`, `status`, `create_by`, `create_time`, `remark`)
+VALUES ('保养计划状态', 'maintenance_plan_status', '0', 'admin', NOW(), '保养计划状态：待执行/已执行/已取消');
+
+-- 2.2 保养计划状态字典数据
+INSERT IGNORE INTO `sys_dict_data` (`dict_sort`, `dict_label`, `dict_value`, `dict_type`, `css_class`, `list_class`, `is_default`, `status`, `create_by`, `create_time`, `remark`)
+VALUES (0, '待执行', '0', 'maintenance_plan_status', NULL, 'warning', 'Y', '0', 'admin', NOW(), '待执行');
+INSERT IGNORE INTO `sys_dict_data` (`dict_sort`, `dict_label`, `dict_value`, `dict_type`, `css_class`, `list_class`, `is_default`, `status`, `create_by`, `create_time`, `remark`)
+VALUES (1, '已执行', '1', 'maintenance_plan_status', NULL, 'success', 'N', '0', 'admin', NOW(), '已执行');
+INSERT IGNORE INTO `sys_dict_data` (`dict_sort`, `dict_label`, `dict_value`, `dict_type`, `css_class`, `list_class`, `is_default`, `status`, `create_by`, `create_time`, `remark`)
+VALUES (2, '已取消', '2', 'maintenance_plan_status', NULL, 'info', 'N', '0', 'admin', NOW(), '已取消');
+
+-- =============================================
+-- 三、回退SQL
+-- =============================================
+
+/*
+-- 删除字典数据
+DELETE FROM `sys_dict_data` WHERE `dict_type` = 'maintenance_plan_status';
+DELETE FROM `sys_dict_type` WHERE `dict_type` = 'maintenance_plan_status';
+
+-- 删除扩展字段
+ALTER TABLE `dm_inspection_plan` DROP COLUMN `planned_time`;
