Java 无法创建配置文件com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:您的SQL语法有错误；

我正在创建简单数据库，下面是我的数据库模式：

create  database studentapp_db ;
create table  students_info
( regno int(10) not null,
firstname varchar (50) ,
middlename varchar (50),
lastname varchar (50),
primary key(regno) ) ;

create table  gaurdian_info
( regno int(10) not null,
gfirstname varchar (50) ,
gmiddlename varchar (50),
glastname varchar (50),
primary key(regno) ) ;

create table  students_otherinfo
( regno int(10) not null,
 isadmin varchar (1) ,
passowrd varchar (50),
primary key(regno) ) ;

现在，我正在从运行配置中插入值，但这给了我这种错误

        }//end of outside class try catch
        } 

        } 

        }

请帮助我了解java

在“学生信息”和“价值观”之间添加空格

而不是

String query3 = "insert into Students_otherinfo" + 
    "values(?,?,?,)" ;

并删除额外的“，”：

编辑：评论后

并用高尔迪安取代了《守护者》，就像《夏姆》中的那样。或者更改模式（更好）.

thanx@Daminox但即使在给空间后，我也会遇到一些其他错误。这是一个新错误，我无法创建配置文件com.mysql.jdbc.exceptions.jdbc4.mysqlsyntaxErrorRexception:表'studentapp\u db.guardian\u info'不存在这是另一个错误，在您的模式中，可以随意用gaurdian替换guardian：D

String query3 = "insert into Students_otherinfo" + 
    "values(?,?,?,)" ;

 String query3 = "insert into Students_otherinfo " + 
    "values(?,?,?)" ;
