驾照理论考试速成,模访一个软件做成的

数据库是mssql2005,在JzData.rar文件中,附加即可;
如果你使用的是sql 2000的数据库,请将debug目录下的access数据库jzdata.mdb转换成sql server数据库,在查询分析器里执行:

exec sp_configure 'show advanced options',1 reconfigure
 exec sp_configure 'Ad Hoc Distributed Queries',1 reconfigure 
create database jz
go
use jz
SELECT *
INTO car
FROM OPENDATASOURCE ('Microsoft.Jet.OLEDB.4.0', 
      'Data Source="D:\GCLsoft\jz\Debug\jzdata.mdb";User ID=Admin;Password=' )...car
SELECT *
INTO moto
FROM OPENDATASOURCE ('Microsoft.Jet.OLEDB.4.0', 
      'Data Source="D:\GCLsoft\jz\Debug\jzdata.mdb";User ID=Admin;Password=' )...moto 
use jz
alter table car alter column id  int  not null  
go  
alter table car add constraint pkKey1 primary key (id)
alter table moto alter column id  int  not null   
go 
alter table moto add constraint pkKey2 primary key (id) --设置主键

数据库名字:jz
代码是C++写的,用vc6打开

在sql2000下,点考试会出现错误:如果语句中包含 UNION 运算符，那么 ORDER BY 子句中的项就必须出现在选择列表中。解决方法,改用视图,在代码里要修改一下:

 if   exists 
(select   *   from   dbo.sysobjects   where   id   =   object_id(N'[dbo].[v1]')   and   OBJECTPROPERTY(id,   N'IsView')   =   1)   
drop view v1
go
create view v1 as
select  top 30 *  from car where zhanjie=1 ORDER BY NEWID()
go
 if   exists 
(select   *   from   dbo.sysobjects   where   id   =   object_id(N'[dbo].[v2]')   and   OBJECTPROPERTY(id,   N'IsView')   =   1)   
drop view v2
go
create view v2 as
select top 20 *  from car where zhanjie=2 ORDER BY NEWID()
go

select * from v1
union all
 select * from v2 

如果不想使用视图,sql语句这样写,也可以解决问题:

select * from
(
    select * from
    (
        select top 30 * from car where zhanjie=1 ORDER BY NEWID()
    ) as a1 
     union  all     
    select * from
    (
        select top 20 * from car where zhanjie=2 ORDER BY NEWID()
    ) as a2
    
) as a3
