Oracle sql 复习题目总结

一解：

select p.promo_name,s.clerk_name,sum(s.sale_amount) top_sale
from promotions p inner join sales s on s.sale_date between p.start_date and p.end_date
group by p.promo_name,p.start_date,p.end_date
having sum(s.sale_amount) > all(
       select sum(s2.sale_amount) from sales s2
       where s.clerk_name <> s2.clerk_name and s2.sale_date between p.start_date and p.end_date
       group by s2.clerk_name
);

二解：

SELECT s1.clerk_name,p.promo_name,p.end_date,SUM(s1.sale_amount)
FROM sales s1 INNER JOIN promotions p ON s1.sale_date BETWEEN p.start_date AND p.end_date
group by s1.clerk_name,p.end_date
HAVING SUM(s1.sale_amount)>= ALL(
        SELECT SUM(s2.sale_amount) FROM sales s2
        WHERE s2.sale_date BETWEEN p.start_date AND p.end_date
        GROUP BY s2.clerk_name
);

财务咨询顾问的收入统计问题
金太阳财务咨询服务公司，聘请了一些财务顾问提供财务操作咨询服务，这些顾问都以兼职形式为公司服务，公司将按小时为顾问工作计算薪酬。具体表信息如下：

a. 顾问信息表 (consultant)

create table consultant(
    cst_id int primary key,cst_name varchar2(30) not null
);
insert into consultant values(1,'david');
insert into consultant values(2,'henry');
insert into consultant values(3,'mary');
insert into consultant values(4,'kent');

b. 顾问费率表 (billings)

不同级别的顾问，在不同的时期，每小时的收费是不同的，公司会根据情况上调或者下调顾问的小时佣金待遇。

create table billings(
    cst_id int not null,bill_date date not null,bill_rate int not null,constraint PK_BILLING PRIMARY KEY(cst_id,bill_date),constraint FK_BILLING_EMP FOREIGN KEY (cst_id) references consultant(cst_id)
);
insert into billings values(1,to_date('2010-1-1',50);
insert into billings values(2,60);
insert into billings values(3,70);
insert into billings values(4,40);
insert into billings values(1,to_date('2011-1-1',60);
insert into billings values(4,45);

c. 顾问工作情况记录表 (hoursworked)

create table hoursworked(
     list_id int primary key,cst_id int not null,work_date date not null,bill_hrs  decimal(5,2) not null,constraint FK_HW_EMP FOREIGN KEY (cst_id) references consultant(cst_id)
   );
insert into hoursworked values(1,to_date('2010-7-1',3);
insert into hoursworked values(2,to_date('2010-8-1',5);
insert into hoursworked values(3,2);
insert into hoursworked values(4,to_date('2011-7-1',4);
insert into hoursworked values(5,3,to_date('2011-8-1',3.5);
insert into hoursworked values(6,4,to_date('2010-9-1',10);
insert into hoursworked values(7,6);

题目

我们编写一个SQL查询语句，显示顾问的名字以及其总的顾问费用。

求解

select c.cst_id,e.cst_name,sum(d.bill_rate*c.bill_hrs) total_fee from (
     select a.cst_id,a.work_date,max(b.bill_date) bill_date,a.bill_hrs
     from billings b inner join hoursworked a
     on a.cst_id=b.cst_id and a.work_date>=b.bill_date
     group by a.cst_id,a.bill_hrs
    ) c,billings d,consultant e
where c.cst_id=d.cst_id and c.bill_date=d.bill_date and c.cst_id=e.cst_id
group by c.cst_id,e.cst_name
order by c.cst_id;
