-- =====================================================
-- 缩短急救宣教相关表名（达梦数据库）
-- 原因：原表名超过数据库限制
-- 日期：2026-08-10
-- =====================================================

-- 1. 急救资源分类表
ALTER TABLE QH_EME_FIRST_AID_RESOURCE_CATEGORY RENAME TO QH_EME_FIR_AID_RES_CATE;

-- 2. 用户操作记录表
ALTER TABLE QH_EME_FIRST_AID_RESOURCE_USER_ACTION RENAME TO QH_EME_FIR_AID_RES_UACT;

-- 3. 资源版本表
ALTER TABLE QH_EME_FIRST_AID_RESOURCE_VERSION RENAME TO QH_EME_FIR_AID_RES_VER;

-- 4. 资源审核表
ALTER TABLE QH_EME_FIRST_AID_RESOURCE_AUDIT RENAME TO QH_EME_FIR_AID_RES_AUD;

-- 5. 推送记录表
ALTER TABLE QH_EME_FIRST_AID_PUSH_RECORD RENAME TO QH_EME_FIR_AID_PUSH_RD;

-- 6. 急救资源主表（最后执行，避免外键依赖）
ALTER TABLE QH_EME_FIRST_AID_RESOURCE RENAME TO QH_EME_FIR_AID_RES;

-- =====================================================
-- 验证：确认新表名已生效
-- SELECT TABLE_NAME FROM USER_TABLES WHERE TABLE_NAME LIKE 'QH_EME_FIR_AID_%';
