利用Mysql进行update时，出现You have an error in your SQL syntax check the manual that corresponds to your My

 总是出现You have an error in your SQL syntax check the manual that corresponds to your MySQL server version for the right syntax ...... at line 1错误。

代码如下：

   ps = conn.prepareStatement("update admin set aid = ?,username = ?,password = ?,password2 = ?"
     + "where aid like ? ");
   ps.setInt(1,admin.getAid());
   ps.setString(2, admin.getUsername());
   ps.setString(3, admin.getPassword());
   ps.setString(4, admin.getPassword2());
   ps.setInt(5, aid);

这段代码没有什么大问题，就是在update的语句中少了个空格！！！

在关键字where后面少了个空格，导致where和参数password2的值连在了一起，出现语法错误。

正确的代码是：
 ps = conn.prepareStatement("update admin set aid = ?,username = ?,password = ?,password2 = ?"
     + " where aid like ? ");
