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 //
create or replace procedure upsert_person (
in pId int unsigned,
in pName varchar(255),
in pDoB date,

as

then

set

select pId as Id;
else
insert into Person

values

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。
