完成存款或取款业务
描述:
Ø 根据银行卡号和交易金额实现银行卡的存款和取款业务。
Ø 每一笔存款,取款业务都要计入银行交易账户,并同时更新客户的存款余额。
Ø 如果是取款业务,在记账之前,要完成下面两项数据的检查验证工作,如果检查不合格,那么中断取款业务,给出提示信息后退出。
² 检查客户输入的密码是否正确。
² 账户取款金额是否大于当前存款额加1。
要求:
Ø 取款或存款存储过程名为usp_takeMoney。
Ø 编写一个存储过程完成存款和取款业务,并调用存储过程取钱或者存钱进行测试,测试数据是张飞的卡号支取100元(密码123456),关羽的卡号存入2100元。

打印客户对账单
为某个特定的银行卡号打印指定时间内发生交易的对账单。要求如下:
Ø 存储过程名称是usp_CheckSheet。
Ø 分别采用以下两种方式执行存储过程,结果如下图所示。
