-- 3. 添加外键约束（可选，根据实际情况）
-- =====================================================
-- ALTER TABLE `jcbt_scholarship_quota`
-- ADD CONSTRAINT `fk_quota_batch` FOREIGN KEY (`batch_id`) REFERENCES `jcbt_scholarship_batch` (`id`);

-- ALTER TABLE `jcbt_scholarship_quota`
-- ADD CONSTRAINT `fk_quota_type` FOREIGN KEY (`scholarship_type_id`) REFERENCES `jcbt_scholarship_type` (`id`);

-- ALTER TABLE `jcbt_scholarship_quota_adjustment`
-- ADD CONSTRAINT `fk_adjustment_quota` FOREIGN KEY (`quota_id`) REFERENCES `jcbt_scholarship_quota` (`id`);

-- =====================================================
-- 4. 验证表创建
-- =====================================================
SHOW TABLES LIKE 'jcbt_scholarship_quota%';
