语法错误，请帮忙看一下
关键语句：String strSql="insert into "+tbName
  +" (ID,Exp,LastVisIP,LeftTime,LoginCount,NickName,Password,"
  +"PostCount,Email,UserName,RegisterDate) values("
  +id+","+exp+","+lastvisip+","+lefttime+","
  +logincount+","+nickname+","+password+","
  +postcount+","+email+","+username+","
  +registerdate+")";
  System.out.println(strSql);

执行后提示语句：

insert into users (ID,Exp,LastVisIP,LeftTime,LoginCount,NickName,Password,PostCount,Email,UserName,RegisterDate) values(1,0,unknown,2012-10-30 15:14:25.362,0,nickname,unknown,0,aa@bb.cc,username,2012-10-30 15:14:25.362)

executeUpdate: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 '15:14:25.362,0,nickname,unknown,0,aa@bb.cc,username,2012-10-30 15:14:25.362)' at line 1


[解决办法]
楼主，你太牛逼了，你这写法全当字段都是数值型的了！
字符型要转成字符串，日期型要转换成日期！
如（加如tbName变量里表的字段id是数值型，exp是字符型）："insert into "+tbName+" (ID,Exp) values ("+id+",'"+exp+"')";
