-- ============================================================
-- 清空「生产物料库」界面相关业务表数据
--
-- 覆盖界面模块：
--   1. 物料列表          → biz_production_material / biz_production_material_stock_batch
--   2. 变动记录          → biz_production_material_usage
--   3. 库存盘点          → biz_production_material_stock_check*
--   4. 配制单            → biz_production_material_prep / biz_production_material_prep_line
--   5. 我的物料领用记录  → biz_production_material_usage（按用户过滤，无独立表）
--   6. 消耗明细          → biz_production_material_usage（prep 关联子记录，无独立表）
--
-- 附加：配置试剂配方 BOM → biz_production_material_formula
--
-- 用法（执行前请先备份）：
--   SET @tenant_no = 'zkxw' COLLATE utf8mb4_unicode_ci;   -- 仅清空指定租户
--   SET @tenant_no = NULL;     -- 清空全部租户（生产环境慎用）
--
-- 说明：
--   - 本脚本为物理 DELETE，包含 del_flag=1 的软删数据
--   - 表间无数据库外键，按业务依赖顺序删除
--   - 生产任务步骤表可能仍保留 requisition_usage_id 快照引用（见文末可选清理）
-- ============================================================

-- 与 biz_production_material* 表 tenant_no 列排序规则一致，避免与 @tenant_no 比较时报 1267
