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 'database='88' where id='1001'' at line 1
代码：mystatement.executeUpdate("update student set math='"+math+"' ,english='"+english+"', computer='"+computer+"' ,database='"+database+"' "+" where id='"+ID+"'");
database是关键字，需要转义
另外确认id类型是字符串么
'database='88' where id='1001''，这附近语法有问题。
