INSERT INTO `t_goods` VALUES (1, 'Iphone 12 64G', 'Iphone 12 64G', '/img/iphone12.png', 'Iphone 12 64G', 5299.00, 100);
INSERT INTO `t_goods` VALUES (2, 'Iphone12Pro128G', 'Iphone12Pro128G', '/img/iphone12pro.png', 'Iphone12Pro128G', 6299.00, 100);
INSERT INTO `t_seckill_goods` VALUES (1, 1, 4299.00, 10, '2022-06-15 00:00:00', '2022-07-15 00:00:00');
INSERT INTO `t_seckill_goods` VALUES (2, 2, 5299.00, 10, '2022-06-15 00:00:00', '2022-07-15 00:00:00');
