在IDEA里面查询自增ID会报错这是为什么？在Navicat都可以

代码：
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/market", "root", "123456");
String sql = "select * from orders ";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()) {
order = new orders();
order.setoID(rs.getInt("orderID"));
System.out.println(“订单ID为”+order.getoID());
order.setoCreateDate(rs.getDate("createDate"));
order.setoTotalPrice(rs.getLong("totalPrice"));
order.setoUserId(rs.getInt("userID"));
System.out.println("订单创建时间为： " + order.getoCreateDate());
System.out.println("订单总价格为： " + order.getoTotalPrice());
System.out.println("操作订单的员工ID为： " + order.getoUserId());
这是报的错误：
java.sql.SQLException: Column 'orderID' not found.
在NaviCat里新建查询 select * from orders 都能够看到有OrderID这个字段

String sql = "select * from orders ";
你这里用的是* ,所以只能用角标数字 0,1,2等拿,
如果你用String sql = "select orderID,createDate from orders ";
,就可以使用rs.getInt("orderID")这种方式了
