-- 20261010 消费机日志记录卡号转换信息（可重复执行）
|
||
--
|
||
-- 背景：部分商户（首个 2078051759222632449）的消费机上报 10 位十进制卡号，服务端按
|
||
-- “十进制 → 8 位大写十六进制 → 字节反转”规则换算成库内卡号后查询钱包
|
||
-- （如 2506198930 → 95618F92 → 928F6195）；排查对账需要在日志表直接看到
|
||
-- 转换前后卡号与转换方式，而不是从 req 原文里人工换算。
|
||
-- 方案：hard_xfj_log 新增三列，均可空，仅刷卡综合接口（consumTransactions）日志填充：
|
||
-- source_card_no 转换前卡号（设备上报原始卡号）
|
||
-- target_card_no 转换后卡号（库内查询卡号，未转换时与转换前一致）
|
||
-- card_convert_type 卡号转换方式（NONE=未转换，DECIMAL_UID_REVERSE=十进制转十六进制字节反转）
|
||
-- 执行：Online DDL，小字段变更，秒级完成。
|
||
-- 回滚：文末 DROP COLUMN。
