我有两张桌子
1:pr_insertion77
create table pr_insertion77(pr_title varchar2(20) primarykey,pr_smalltitle varchar2(20),pr_desc varchar2(100),pr_category varchar2(20),
pr_startdate date,pr_enddate date,pr_bidtype number(2),pr_image long raw);
2:卖家详情
create table sellerdetails( sellername varchar2(20),biddedproduct varchar2(20),price number(10),CONSTRAINT fk_pr_insertion77
FOREIGN KEY (biddedproduct)
REFERENCES pr_insertion77(pr_title)
我想在哪里获得卖家名称和价格pr_insertion77.pr_title=sellerdetails.biddedproduct.
