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。这种错误是因为sql格式不对，记住要在imooc_goddess 后面加上空格。修改后，注意空格 String sql=" "+ "delete from imooc_goddess " + "where id=?";

报了这个错误的朋友，你可能不是sql语句写错了，而是ptmt.excute()函数里面加了sql参数，用PreparedStatement对象来实现的话不用带参数的
JDBC连接数据库避免中文乱码：在数据库URL后添加字符限制private static final String URL="jdbc:mysql://127.0.0.1:3306/imooc?useUnicode=true&characterEncoding=utf8";注意噢，是直接在URL后面添加，不是分两行写
