This application uses OleDb as a backhand communicator with the file to allow the user to : select, delete, insert and modify the database and then save all the changes to the original file.
The goal of this library is to make ODBC recordsets look just like an STL container. As a user, you can move through our containers using standard STL iterators and if you insert(), erase() or replace() records in our containers changes can be automatically committed to the database for you. The library s compliance with the STL iterator and container standards means you can plug our abstractions into a wide variety of STL algorithms for data storage, searching and manipulation. In addition, the C++ reflection mechanism used by our library to bind to database tables allows us to add generic indexing and lookup properties to our containers with no special code required from the end-user. Because our code takes full advantage of the template mechanism, it adds minimal overhead compared with using raw ODBC calls to access a database.

4、 編寫一個(gè)過程。要求：有一個(gè)輸入?yún)?shù)和一個(gè)輸出參數(shù)，過程里面要有自定義異常。從學(xué)生表中（tab_student）中尋找符合指定學(xué)號(hào)等于輸入?yún)?shù)的值，然后將找到的學(xué)生的姓名賦予輸出參數(shù)，如果沒有符合條件的值則觸發(fā)異常。
Create table tab_student
(sno char(8),
sname varchar2(20),
age integer,
province varchar2(60),
sex char(4))
insert into tab_student values(‘001’,’zhou’,20,’江蘇徐州’,’男’)
上述表已經(jīng)創(chuàng)建，只需針對(duì)此表編寫即可。
