大侠:机经中有一道题:2. Merge statement in data procedure o proc sql; FULL join with coalesce() function。 请问问的是什么?另外,proc sql;
create table forecast as
select a.*, b.sales
from actual a, _________
where a.dept=b.dept;
quit;
Answer:
(select avg(revenue) as average
from Budegt
group by 1) b
这道题中,budegt是不是应该是budget ?
