执行上面的语句没问题,但是我想加一个合计

因些加上了上面红色的代码,但是报错误提示:

请大家帮忙看一下是什么原因,谢谢大家了

中的b又是从哪儿来的?

order by t1.lineid,2,t2.speedlevel
UNION 之后的ORDER BY 比较烦
比如
select 1 as aa from dual a
order by a.dummy这样不出错,但是UNION之后
select 1 as dummy from dual a
union all
select 2 from dual a
order by a.dummy
这样就不行了
你可以直接改成
order by 1,3
