-- 1. 创建钱包表
-- =====================================================

-- 2. 创建钱包交易记录表
-- =====================================================

-- =====================================================
-- 3. 插入测试数据
-- =====================================================

-- 为测试用户创建钱包（假设用户ID为1）
INSERT INTO `wallet` (`user_id`, `balance`, `frozen_amount`, `total_recharge`, `total_consume`, `total_withdraw`, `points`, `status`, `version`, `tenant_id`)
VALUES 
(1, 0.00, 0.00, 0.00, 0.00, 0.00, 0, 1, 0, 1),
(2, 0.00, 0.00, 0.00, 0.00, 0.00, 0, 1, 0, 1),
(3, 0.00, 0.00, 0.00, 0.00, 0.00, 0, 1, 0, 1)
ON DUPLICATE KEY UPDATE `updated_time` = CURRENT_TIMESTAMP;

-- =====================================================
-- 4. 验证表创建
-- =====================================================
SELECT '钱包表创建完成' AS message;
SELECT COUNT(*) AS wallet_count FROM `wallet`;

SELECT '钱包交易记录表创建完成' AS message;
SELECT COUNT(*) AS transaction_count FROM `wallet_transaction`;

-- =====================================================
-- 5. 显示表结构
-- =====================================================
SHOW CREATE TABLE `wallet`;
SHOW CREATE TABLE `wallet_transaction`;

-- =====================================================
-- 执行完成
-- =====================================================
SELECT '✅ 钱包系统数据库表创建完成！' AS result;
