MariaDB模式创建

Question

我正在尝试在MariaDB中定义一组对象，即

scoreList.size()

但是我一直遇到的错误是

use SocialCartography;

drop table if exists Relationship;
drop table if exists Person;

create table if not exists Person (
    Id int unsigned not null auto_increment primary key,
    Name varchar(255) null, 
    DoB date null,
    DoD date null,
    PictureURL varchar(8192) null
);

create table if not exists Relationship (
    Id int unsigned not null auto_increment primary key,
    Since date null,
    Until date null,
    Type varchar(255),
    First int unsigned not null,
    Second int unsigned not null,
    PictureURL varchar(8192) null,

    constraint `fk_first_friend` 
    foreign key (first) references Person (Id)
        on delete cascade
        on update restrict,

    constraint `fk_second_friend` 
    foreign key (second) references Person (Id)
        on delete cascade
        on update restrict
);
go

delimiter //

    in pId int unsigned,

知道我在做什么错吗？我已经尝试过nvarchar，但是又恢复为varchar，因为我找不到有关如何使用nvarchar的文档。

该错误消息似乎没有太大帮助，因为我试图在所示语法附近找到错误，但没有找到。

摆脱go；属于其他产品。

OR REPLACE直到10.1.3才可用；您正在运行什么版本？
