group by t1.lineid,t2.speedlevel
order by t1.lineid,t2.speedlevel
执行上面的语句没问题,但是我想加一个合计
select distinct t1.lineid,'' as linesum,t2.speedlevel,sum(decode(t2.exceptionitem,0,t2.level4count,0)) as a from pw_run_record t1,pw_detect_exceptionstatic t2,pw_detect_tqistatic t3 where t1.detectid=t2.detectid and t1.detectid=t3.detectid
union all
select distinct t1.lineid,'合计' as linesum,t2.speedlevel,sum(decode(t2.exceptionitem,0,t2.level4count,0)) as a from pw_run_record t1,pw_detect_exceptionstatic t2,pw_detect_tqistatic t3 where t1.detectid=t2.detectid and t1.detectid=t3.detectid
group by t1.lineid,t2.speedlevel
order by t1.lineid,t2.speedlevel
因些加上了上面红色的代码,但是报错误提示:
ORA-00904:t2.speedlevel标识符无效
请大家帮忙看一下是什么原因,谢谢大家了
10 个解决方案
#1
加合计不用单独加的嘛
--例如
SQL> with a as (
2 select 'a' A, 'b' B ,5 C ,2 D from dual
3 union all
4 select 'w', 'b', 1, 3 from dual
5 union all
6 select 'x' ,'x' ,3 ,1 from dual
7 )
8 select decode(grouping(A),1,'合計',A) A
9 ,B,sum(C) C,SUM(D) D
10 from a
11 group by rollup ((a,b))
12 /
A B C D
---- - ---------- ----------
a b 5 2
w b 1 3
x x 3 1
合計 9 6
#2
没看懂,您的意思是我就不用union all 了,rollup ((a,b))
中的b又是从哪儿来的?

select decode(grouping(t1.lineid),1,'合計',t1.lineid) lineid,t2.speedlevel,sum(decode(t2.exceptionitem,0,t2.level4count,0)) as a from pw_run_record t1,pw_detect_exceptionstatic t2,pw_detect_tqistatic t3
where t1.detectid=t2.detectid
and t1.detectid=t3.detectid
group by rollup ((t1.lineid,t2.speedlevel))
order by lineid,t2.speedlevel
#4
select distinct t1.lineid,decode(grouping(t2.speedlevel),1,'合计') as linesum,
t2.speedlevel,sum(decode(t2.exceptionitem,0,t2.level4count,0)) as a from pw_run_record t1,pw_detect_exceptionstatic t2,pw_detect_tqistatic t3 where t1.detectid=t2.detectid and t1.detectid=t3.detectid
group by t1.lineid,rollup(t2.speedlevel)
order by t1.lineid,2,t2.speedlevel
#5
你出错的原因是ORDER BY
UNION 之后的ORDER BY 比较烦
比如
这样不出错,但是UNION之后
你可以直接改成
order by 1,3
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这样就不行了
union all
select 2 from dual a
order by a.dummy
你可以直接改成
order by 1,3

我的问题还有一个,我的这个表里需要小计和合计,合计固定最后一列,但是小计是任意组合的,我从界面任意组合选择需要小计的字段后,然后语句里就会根据出现的字段进行小计,所以上面的大家的建议我不知道怎么弄

-----使用union all 是先组合,然后再排序列,所以你使用的 order by t1.lineid, t2.speedlevel并不是来自t1,和t2表
