我尝试在我的应用程序中添加新类。一切都很好，直到我添加Boolean read。当我把它添加到我的班级时，我得到：
We got the following error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'read tinyint(1) default 0, constraint ck_event_type check (' at line 7 [ERROR:1064, SQLSTATE:42000], while trying to run this SQL script:
以及脚本的重要部分：
create table event (
id bigint auto_increment not null,
type varchar(14) not null,
user_id bigint,
message varchar(255) not null,
date date,
read tinyint(1) default 0,
constraint ck_event_type check (type in ('game_started','game_completed','wrong_answer','correct_answer','wrong_location')),
constraint pk_event primary key (id))
我不知道问题是什么。我在其他类中声明了布尔值，没有问题。我正在使用play 2.2.1
我的课程：
