索引和视图

–1.创建索引：给交易表的卡号cardID字段创建重复索引
create NONCLUSTERED INDEX index_cardID ON transInfo(cardID)WITH FILLFACTOR=70
–2.按指定索引查询张三（卡号为1010 3576 1212 1134）的交易记录
GO
SELECT * FROM transInfo (INDEX=index_cardID) WHERE cardID=’1010 3576 1234 5678′
GO
–3.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。
create VIEW view_userInfo –银行卡信息表视图
AS
select customerID as 客户编号,customerName as 开户名, PID as 身份证号,
telephone as 电话号码,address as 居住地址 from userInfo
GO
create VIEW view_cardInfo –银行卡信息表视图
AS
select cardID as 卡号,curType as 货币种类, savingType as 存款类型,openDate as 开户日期,
balance as 余额,pass 密码,IsReportLoss as 是否挂失,customerID as 客户编号 from cardInfo
GO
create VIEW view_transInfo –交易信息表视图
AS
select transDate as 交易日期,transType as 交易类型, cardID as 卡号,transMoney as 交易金额,
remark as 备注 from transInfo

存储过程

–1.取钱或存钱的存储过程
–drop proc proc_takeMoney
create procedure proc_takeMoney @card char(19),@m money,@type char(4),@inputPass char(6)=”
AS
print ‘交易正进行,请稍后……’
if (@type=’支取’)
if ((SELECT pass FROM cardInfo WHERE cardID=@card)<>@inputPass )
begin
raiserror (‘密码错误!’,16,1)
return
end
DECLARE @myTransType char(4),@outMoney MONEY,@myCardID char(19)

DECLARE @mybalance money
SELECT @mybalance=balance FROM cardInfo WHERE cardID=@card

print ‘卡号’+@card+’ 余额：’+convert(varchar(20),@mybalance)
INSERT INTO transInfo(transType,cardID,transMoney) VALUES(@type,@card,@m)
GO
–2.调用存储过程取钱或存钱张三取300，李四存500
–现实中的取款机依靠读卡器读出张三的卡号,这里根据张三的名字查出考号来模拟
declare @card char(19)
select @card=cardID from cardInfo Inner Join userInfo ON
cardInfo.customerID=userInfo.customerID where customerName=’张三’
EXEC proc_takeMoney @card,300 ,’支取’,’123456′
GO
declare @card char(19)

cardInfo.customerID=userInfo.customerID where customerName=’李四’
EXEC proc_takeMoney @card,500 ,’存入’
select * from view_cardInfo
select * from view_transInfo
GO
–3.产生随机卡号的存储过程(一般用当前月份数\当前秒数\当前毫秒数乘以一定的系数作为随机种子)
–drop proc proc_randCardID
create procedure proc_randCardID @randCardID char(19) OUTPUT
AS
DECLARE @r numeric(15,8)
DECLARE @tempStr char(10)
SELECT @r=RAND((DATEPART(mm, GETDATE()) * 100000 )+ (DATEPART(ss, GETDATE()) * 1000 )
+ DATEPART(ms, GETDATE()) )
set @tempStr=convert(char(10),@r) –产生0.xxxxxxxx的数字,我们需要小数点后的八位数字
set @randCardID=’1010 3576 ‘+SUBSTRING(@tempStr,3,4)+’ ‘+SUBSTRING(@tempStr,7,4) –组合为规定格式的卡号
GO
–4.测试产生随机卡号
DECLARE @mycardID char(19)
EXECUTE proc_randCardID @mycardID OUTPUT
print ‘产生的随机卡号为：’+@mycardID
GO
–5.开户的存储过程
–drop proc proc_openAccount
create procedure proc_openAccount @customerName char(8),@PID char(18),@telephone char(13)
,@openMoney money,@savingType char(8),@address varchar(50)=”
AS
DECLARE @mycardID char(19),@cur_customerID int
–调用产生随机卡号的存储过程获得随机卡号
EXECUTE proc_randCardID @mycardID OUTPUT
while exists(SELECT * FROM cardInfo WHERE cardID=@mycardID)
EXECUTE proc_randCardID @mycardID OUTPUT
print ‘尊敬的客户,开户成功!系统为您产生的随机卡号为:’+@mycardID
print ‘开户日期’+convert(char(10),getdate(),111)+’ 开户金额:’+convert(varchar(20),@openMoney)
IF not exists(select * from userInfo where PID=@PID)
INSERT INTO userInfo(customerName,PID,telephone,address )
VALUES(@customerName,@PID,@telephone,@address)
select @cur_customerID=customerID from userInfo where PID=@PID
INSERT INTO cardInfo(cardID,savingType,openMoney,balance,customerID)
VALUES(@mycardID,@savingType,@openMoney,@openMoney,@cur_customerID)
GO
–6.调用存储过程重新开户
EXEC proc_openAccount ‘王五’,’334456889012678′,’2222-63598978′,1000,’活期’,’河南新乡’
EXEC proc_openAccount ‘赵二’,’213445678912342222′,’0760-44446666′,1,’定期’
select * from view_userInfo
select * from view_cardInfo

/*
事务

–1.转帐的事务存储过程
–drop proc proc_transfer
create procedure proc_transfer @card1 char(19),@card2 char(19),@outmoney money
AS
begin tran
print ‘开始转帐,请稍后……’
DECLARE @errors int
set @errors=0

set @errors=@errors+@@error
if (@errors>0)
begin
print ‘转帐失败！’
rollback tran
end
else
begin
print ‘转帐成功！’
commit tran
end
GO
–2.测试上述事务存储过程
–从李四的帐户转帐2000到张三的帐户
–同上一样,现实中的取款机依靠读卡器读出张三/李四的卡号,这里根据张三/李四的名字查出考号来模拟
declare @card1 char(19),@card2 char(19)
select @card1=cardID from cardInfo Inner Join userInfo ON
cardInfo.customerID=userInfo.customerID where customerName=’李四’
select @card2=cardID from cardInfo Inner Join userInfo ON
cardInfo.customerID=userInfo.customerID where customerName=’张三’
–调用上述事务过程转帐
EXEC proc_transfer @card1,@card2,2000
select * from view_userInfo
select * from view_cardInfo
select * from view_transInfo
GO
/*
安全

–1.添加SQL登录帐号
If not exists(SELECT * FROM master.dbo.syslogins WHERE loginname=’sysAdmin’)
begin
EXEC sp_addlogin ‘sysAdmin’, ‘1234’ –添加SQL登录帐号
EXEC sp_defaultdb ‘sysAdmin’ , ‘bankDB’ –修改登录的默认数据库为bankDB
end
go
–2.创建数据库用户
EXEC sp_grantdbaccess ‘sysAdmin’, ‘sysAdminDBUser’
GO
–3.——–给数据库用户授权
–为sysAdminDBUser分配对象权限(增删改查的权限)
GRANT SELECT,insert,update,delete,select ON transInfo TO sysAdminDBUser
GRANT SELECT,insert,update,delete,select ON userInfo TO sysAdminDBUser
GRANT SELECT,insert,update,delete,select ON cardInfo TO sysAdminDBUser
