Answer 1

這一個怎麼樣？

SELECT sum(rpl) AS rpl, sum(estcomm) as commission,decrip 
from COMM c, BOOK b 
    WHERE b.bookid=c.parbookid 
     and (booktype='trading' OR booktype='wash) 
    GROUP BY b.decrip 

Answer 2

嘗試是這樣的（假設booktype是一列下BOOK表）

SELECT sum(c.rpl) AS rpl,sum(c.estcomm) as commission,b.decrip 
from COMM c 
join BOOK b 
on b.bookid=c.parbookid 
where b.booktype in('trading','wash') 
GROUP BY b.decrip
