二、问答题

-- ITEM
-- SHIPMENT
-- SHIPMENT_ITEM

-- A.列出所有表的数据
select * from ITEM;
select * from SHIPMENT;
select * from SHIPMENT_ITEM;

-- B.列出所有船运的ShipmentID, ShipperName和ShipperInvoiceNumber
select ShipmentID, ShipperName, ShipperInvoiceNumber from SHIPMENT;

-- C.列出所有保险额超过10000元的船运的ShipmentID, ShipperName和ShipperInvoiceNumber
select ShipmentID, ShipperName, ShipperInvoiceNumber
from SHIPMENT
where InsuredValue > 10000;

-- D.列出所有名字以‘AB‘开头的船运的ShipmentID, ShipperName和ShipperInvoiceNumber
select ShipmentID, ShipperName, ShipperInvoiceNumber
from SHIPMENT
where ShipperName like ‘AB%‘;

-- E.假设Departure和ArrivalDate的格式为月/日/年.列出所有于12月出发的船运ShipmentID,
-- ShipperName, ShipperInvoiceNumber和ArrivalDate
select ShipmentID, ShipperName, ShipperInvoiceNumber, ArrivalDate
from SHIPMENT
where month(DepartureDate) = 12;

-- F.假设Departure和ArrivalDate的格式为月/日/年.列出所有于某月10日出发的船运ShipmentID,
-- ShipperName, ShipperInvoiceNumber和ArrivalDate
select ShipmentID, ShipperName, ShipperInvoiceNumber, ArrivalDate
from SHIPMENT
where day(DepartureDate) = 10;

-- G.确定最大值和最小值的InsuredValue
select max(InsuredValue) as maxInsuredValue,
min(InsuredValue) as minInsuredValue
from SHIPMENT;

-- H.确定平均的InsuredValue
select avg(InsuredValue) from SHIPMENT;

-- I.计算船运的总数
select count(*) from SHIPMENT;

-- J.对于表ITEM_PURCHASE中的每一行, 显示Item, Store和一个计算得到的名为
-- StdCurrencyAmount的列。该列的值为LocalCurrencyAmt乘以ExchangeRate
select ItemID, Store, LocalCurrencyAmount * ExchangeRate as StdCurrencyAmount
from ITEM;

-- K.按照City和Store对购买的物品进行分组
select ITEM.City, ITEM.Store from ITEM
group by ITEM.City, ITEM.Store;

-- L.按照City和Store对购买的物品进行分组, 计算每组的数目
select ITEM.City, ITEM.Store, count(*) as n from ITEM
group by ITEM.City, ITEM.Store;

-- M.使用子查询, 显示所有包含单价超过1000的物品船运的ShipperName
-- ShipmentID和DepartureDate. 结果先按照ShipperName升序排序, 再按照DepartureDate降序排序
select  SHIPMENT.ShipperName, SHIPMENT.ShipmentId, SHIPMENT.DepartureDate
from SHIPMENT
where
SHIPMENT.ShipmentId
in
(select distinct SHIPMENT_ITEM.ShipmentID from SHIPMENT_ITEM where Value > 1000)
order by SHIPMENT.ShipperName asc, SHIPMENT.DepartureDate desc;

-- O.使用子查询, 显示所有包含在新加坡购买的物品船运的ShipperName
-- ShipmentID和DepartureDate. 结果先按照ShipperName升序排序, 再按照DepartureDate降序排序s
select  SHIPMENT.ShipperName, SHIPMENT.ShipmentId, SHIPMENT.DepartureDate
from SHIPMENT
where
SHIPMENT.ShipmentId  in
(select ShipmentID from SHIPMENT_ITEM where SHIPMENT_ITEM.ItemID in (select ItemId from ITEM where ITEM.City = ‘Singapore‘)
)
order by SHIPMENT.ShipperName asc, SHIPMENT.DepartureDate desc;
