-- （若未执行过误删可跳过本段，重复执行亦安全）
-- ================================================================

SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci;

-- 1) 恢复「单体设备 / 核心单体设备」根分类
UPDATE f_product_category
SET del_flag = 0
WHERE del_flag = 1
  AND name_zh IN ('单体设备', '核心单体设备');

-- 2) 恢复挂在上述根下的子分类（名称关联，不要求 module_type 已正确）
UPDATE f_product_category child
INNER JOIN f_product_category parent ON parent.product_category_id = child.parent_id
SET child.del_flag = 0
WHERE child.del_flag = 1
  AND parent.name_zh IN ('单体设备', '核心单体设备');

-- 3) 恢复历史上常用的单体子目录 ID 段（migration 51–62、图册 200–205）
UPDATE f_product_category
SET del_flag = 0
WHERE del_flag = 1
  AND (
    product_category_id BETWEEN 51 AND 62
    OR product_category_id BETWEEN 200 AND 205
  );

-- 4) 恢复单体设备根上 module_type = equipment 但被软删的行（若有）
UPDATE f_product_category
SET del_flag = 0
WHERE del_flag = 1
  AND module_type = 'equipment'
  AND (parent_id IS NULL OR parent_id = 0);

-- 5) 恢复 f_single_equipment：分类属 equipment，或挂在已知单体分类 ID 上
UPDATE f_single_equipment se
LEFT JOIN f_product_category pc ON pc.product_category_id = se.category_id AND pc.del_flag = 0
SET se.del_flag = 0
WHERE se.del_flag = 1
  AND (
    pc.module_type = 'equipment'
    OR se.category_id BETWEEN 51 AND 62
    OR se.category_id BETWEEN 200 AND 205
    OR se.category_id = 5
  );
