--用例4
--1.修改密码
update  cardInfo set pass='123456 '--张三123456
where cardID='1010 3576 1234 5678'
update  cardInfo set pass='222222'--李四123123
where cardID='1010 3576 1212 1130'

----2.办理银行卡挂失-----------------
--描述：李四（卡号为1010357612121134）因银行卡丢失，申请挂失
update  cardInfo set IsReportLoss=1
where cardID='1010 3576 1212 1130'

--3.统计银行流通余额，盈利结算
declare @inmoney money     --声明一个总存入的变量
declare @outmoney money    --声明一个总支取的变量
select @inmoney=SUM(trademoney) from tradeInfo where tradeType='存入'
select @outmoney=SUM(trademoney) from tradeInfo where tradeType='支取'
print '银行流通余额总计为:'+convert(varchar(20),@inmoney-@outmoney)+'RMB'
print '盈利结算为:'+convert(varchar(20),@outmoney*0.008-@inmoney*0.003)+'RMB'
go

--4.查询本周开户信息
select * from cardInfo where 
DATEDIFF(weekday,opendate,GETDATE())<DATEPART(weekday,GETDATE())

--5.查询本月交易金额最多的卡号
--存入最多
select * from tradeInfo where
tradeMoney=(select MAX(tradeMoney) from tradeInfo where
tradeType='存入' and DATEDIFF(MONTH,tradeDate,GETDATE())<=1)

--支取最多
select * from tradeInfo where
 tradeMoney=(select MAX(tradeMoney) from tradeInfo where
 tradeType='支取' and DATEDIFF(MONTH,tradeDate,GETDATE())<=1)

--6.查询挂失的卡号
select * from userInfo where
customerID in(select customerID from cardInfo where IsReportLoss=1)

--7.催款提醒业务
select customername from userInfo inner join cardInfo
on cardInfo.customerID=userInfo.customerID where balance<200

--1.创建视图：为了向客户显示信息友好,查询各表要求字段全为中文字段名。

    select c.cardID as 卡号,u.customerName as 客户,c.curID as 货币种类, d.savingName as 存款类型,c.openDate as 开户日期,

    from cardInfo c, deposit d,userinfo u
    where c.savingID=d.savingID and c.customerID=u.customerID

--3.创建视图：查看交易信息
if exists (select * from sysobjects where name = 'vw_tradeInfo')
 drop view vw_tradeInfo
go
create VIEW vw_tradeInfo  --交易信息表视图
  AS
    select tradeDate as 交易日期,tradeType as 交易类型, cardID as 卡号,tradeMoney as 交易金额,
