问题是当更新后数据库记录指针移到了最后一条,而rs.next()记录的是上第一条,所以无法移动,请帮助如何处理如何采用循环更新所有记录

try{
.............数据库正常连接
String SQLUpdate;
String SQLSelect;
SQLUpdate = "update mydb.tt set ws = ";
SQLSelect = "select numid,one,two,three from tt";
ResultSet rs = stmt.executeQuery(SQLSelect);

while (rs.next()){

String X0 = rs.getString("numid");
int X1 = rs.getInt("one");
int X2 = rs.getInt("two");
int X3 = rs.getInt("three");

int aX = X1+X2+X3;

stmt.executeUpdate("update mydb.tt set ws = '" + aX + "' where numid = '" + X0+"'") ;

}

rs.close();
stmt.close();
mysqlCon.close();

}
catch(SQLException ex){
System.err.println("数据库连接失败！！");
ex.printStackTrace();
}
}
}
