oracle语句与SQL的转换，谢谢了

//客户退房后记录存入历史记录表 这是用oracle写出来的我对应写出来的sql有问题吗
create or replace TRIGGER deletecustomer
after delete
on customer
for each row
declare
ldate date;
money number;
begin
account(:OLD.RID,:OLD.rdate,ldate,money);
insert into history values
(id_seq.nextval,:OLD.CID,:OLD.RID,:OLD.cname,:OLD.csex,:OLD.ctel,:OLD.rdate,ldate,money);
end deletecustomer;
