mybatis多表查询

Question

mybatis多表查询时字段的值已经查出来了但是打印的结果却是0
SQL语句如下

 select order_detailed.order_id,goods_name,price,id,quantity from goods1,`order`,order_detailed where order.order_id=order_detailed.order_id and goods1.id=order_detailed.goods_id and order_detailed.order_id=#{orderId}

order_detailed.order_id这值通过日志看已经查出来了但是输出后是0

Answer 1

为什么带表名
