    `__raw_id`    varchar(255) CHARACTER SET utf8 NOT NULL,
    `guard`       varchar(255) CHARACTER SET utf8          DEFAULT NULL,
    `user_id`     int                                      DEFAULT NULL,
    `id`          int                             NOT NULL,
    `name`        varchar(255) CHARACTER SET utf8 NOT NULL,
    `qty`         int                             NOT NULL,
    `price`       decimal(8, 2)                   NOT NULL,
    `total`       decimal(8, 2)                   NOT NULL,
    `__model`     varchar(255) CHARACTER SET utf8          DEFAULT NULL,
    `type`        varchar(255) CHARACTER SET utf8          DEFAULT NULL,
    `status`      varchar(255) CHARACTER SET utf8          DEFAULT NULL,
    `attributes`  text CHARACTER SET utf8,
    `create_time` timestamp                       NOT NULL DEFAULT CURRENT_TIMESTAMP,
