FAILED: ParseException line 1:78 cannot recognize input near 'exchange' ',' 'routing_key' in selection target

运行的代码：

一个很简单的的语句

insert overwrite table inventory_sendmq_failed select id,exchange,routing_key,queue,body,create_time,error_msg,remark from (select *, row_number() over (partition by id order by ts desc,sort_id desc) as od from ods——inventory_sendmq_failed ) inventory_sendmq_failed  where od = 1;

原因：

有字段带有下划线或者与系统中字段重名

解决方案：

在字段外边加上飘号``

飘号是键盘靠近左上角位置，标记有~和`的那个键。

 `id`,`exchange`,`routing_key`

最终结果：

成功运行
