-- 1.0.553.verify.sql — 每条 SELECT 都必须返回 1

-- ① 唯一键存在，且恰好 2 列
SELECT (SELECT COUNT(*) FROM information_schema.`STATISTICS`
         WHERE `TABLE_SCHEMA` = DATABASE() AND `TABLE_NAME` = 'mdp_inbound_grant'
           AND `INDEX_NAME` = 'uk_inbound_grant' AND `NON_UNIQUE` = 0) = 2;

-- ② 列序完全正确（access_key 在前，entity_code 在后）
SELECT (SELECT GROUP_CONCAT(`COLUMN_NAME` ORDER BY `SEQ_IN_INDEX` SEPARATOR ',')
          FROM information_schema.`STATISTICS`
         WHERE `TABLE_SCHEMA` = DATABASE() AND `TABLE_NAME` = 'mdp_inbound_grant'
           AND `INDEX_NAME` = 'uk_inbound_grant') = 'access_key,entity_code';

-- ③ 数据层无重复（唯一键生效的必要条件，也防止有人事后禁用校验塞重复）
SELECT (SELECT COUNT(*) FROM (
          SELECT 1 FROM `mdp_inbound_grant` GROUP BY `access_key`, `entity_code` HAVING COUNT(*) > 1
        ) d) = 0;

-- ④ 授权行未被本次热修误删（只加索引，不动数据）
SELECT (SELECT COUNT(*) FROM `mdp_inbound_grant`) > 0;

-- ⑤ 其余四张 inbound 表未被波及（本批只改 grant 一张）
SELECT (SELECT COUNT(*) FROM information_schema.`TABLES`
         WHERE `TABLE_SCHEMA` = DATABASE() AND `TABLE_NAME` LIKE 'mdp\_inbound\_%') = 5;
