-- =====================================================
-- 数据库字符集修复脚本
-- 用途：修复已有数据库中 COMMENT 乱码问题
-- 原因：建表时未指定 DEFAULT CHARSET=utf8mb4，
--       导致表继承数据库默认字符集（如 latin1），
--       中文 COMMENT 在存储时被错误编码
-- 用法：连接 MySQL 后执行此脚本
-- 注意：建议先备份数据库！
-- =====================================================

-- 1. 先修改数据库默认字符集（影响后续新建表）
ALTER DATABASE risk_control CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

-- =====================================================
-- 2. 修改风控模块表（riskctrl.sql）
-- =====================================================
ALTER TABLE risk_rule          CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
ALTER TABLE risk_event         CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
ALTER TABLE risk_case          CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
ALTER TABLE risk_blacklist     CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
ALTER TABLE risk_whitelist     CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
ALTER TABLE risk_score         CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

-- =====================================================
-- 3. 修改系统核心表（init.sql / ry_vue_5.X.sql）
-- =====================================================

ALTER TABLE sys_client         CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

-- =====================================================
