我想结合这两个查询的结果:

SELECT odate, 
       Count(odate), 
       Sum(dur) 
FROM   table1 t1 
GROUP  BY odate 
ORDER  BY odate; 

SELECT cdate, 
       Count(cdate), 
       Sum(dur) 
FROM   table2 t2 
GROUP  BY cdate 
ORDER  BY cdate; 

并得到这样的结果:

odate,t1.count(odate),t2.sum(dur),t2.count(cdate),t2.sum(dur) order by odate

怎么做？

我运行这个时遇到错误:

select odate,count(odate),sum(dur) 
from table1 t1 
group by odate 
order by odate 
union 
select cdate,count(cdate),sum(dur) 
from table2 t2 
group by cdate 
order by cdate;
