1.我用Rose 生成的DDL Script文件(创建table),在SQL上怎么执行,我试验了一下添加任务,但是script太长了,不可以.rn2.关于一些列,我用了自动添加,例如rnCREATE TABLE PurchaseOrder (rn OrderID INTEGER IDENTITY NOT NULL,rn OrderDate DATE NOT NULL,rn UnitPrice DECIMAL NOT NULL,rn Quantity SMALLINT NOT NULL,rn ProductID INTEGER NOT NULL,rn EmployeeID INTEGER IDENTITY NOT NULL,rn CONSTRAINT PK_PurchaseOrder19 PRIMARY KEY (OrderID)rn );rnOrderID是每次添加纪录时候自动添加的.但是问题在于插入纪录时候.我用VC的,rnInsert into PurchaseOrderrnVALUE 中间要包含OrderID还是去掉呢.给我写一下好码?rnrn3. 在每次插入新纪录我要得到OrderID的值怎么做呢?有人说在刚才的语句后面接一个SELECT @@IDENTITY就可以了.对于上面的例子,具体怎么用呢?让他可以返回一个值.只要告诉我在SQL里面具体怎么做到就可以了,我会转到C++中的.rnrn4. 最后问一下关于上面的DATA, CURRENCY, DECIMAL如果是UPDATE语句该怎么设置呢? 例如SET OrderDate = '02/25/1998',rn SET UnitPrice = 3.45rn SET Price = 25.56 (假设Price是currency)rn正确的应该是什么呢?rnrn

设计题目:农夫果园rn 一个农场,专门种植销售各类水果,在这个系统中需要描述下列水果:rn 葡萄:Grapern 草莓:Strawberryrn 苹果:Applern 水果与其他的植物有很大的不同,水果最终是可以采摘食用的。那么一个自然的做法就是建立一个各种水果都适用的接口,以便与农场里的其他植物区分开。水果接口规定出所有的水果都必须实现的接口,包括任何水果必须具备的方法:种植plant(),生长grow(),收获harvest()。rn Apple类是水果中的一种,因此它实现了水果接口所声明的所有方法。另外,由于苹果是多年生植物,因此多出一个treeAge性质,描述苹果树的树龄。rn Grape类是水果类的一种,也实现Fruit接口中所声明的所有方法。但由于葡萄分为有籽和无籽的两种,因此比通常的水果多出一个seedless性质。rn Strawberry类也是水果的一种,也实现了Fruit接口。rn 农场的园丁也是系统的一部分,自然要由一个合适的类来代表。这个类就是FruitGardener,它会根据农场老板的要求,使用factory()方法创建出不同的水果对象,比如苹果(Apple),葡萄(Grape)或草莓(Strawberry)的实例。而如果接到不合法的要求,会提示错误。rn 农场的市场调查员也是系统的一部分,也需要一个类代表,这个类是MarketInquirer,它通过inquire()调查今年市场上哪一种水果热销。rn 农场的老板也是系统的一部分,仍需要一个类来代表,这个类是FruitBoss,他会根据市场调查员的反馈信息,通知农场的园丁今年种植哪种水果。rn 要求:请你根据上述系统需求,用Java语言设计这个农场系统,发挥你的想象力吧!rnrn 祝你的农场百果丰收!rn

Hi, gurusrnI'm developing an editor using Visual C++ 6.0, and I plan to add some new features to it:rn1. read from .class and .jar files and show the classes, operations, etc. in the editor;rn2. to compile the .java files edited in my editor.rnI know sun.tools.javac.Main and the reflection/introspector mechanism in java can <em>help</em>, but how to utilize them in a program developed in VC? that is, how can I turn a pure java module into a part of VC program, and make these two cooperate well? VJ seems to be more compatible with VC, but there's something missing in it classes, e.g., sun.tools.javac.Main.rnPlease give me some advice.

Web Api 的 路由机制
ASP.NET Web API 是一种框架,用于轻松构建可以访问多种客户端(包括浏览器和移动设备)的 HTTP 服务。 ASP.NET Web API 是一种用于在 .NET Framework 上构建 RESTful 应用程序的理想平台。所以我们要想学习web api 就要去了解它的路由机制。MVC和web api的路由机制的主要区别是web api 使用的是http 方法而不是url 的路径。本
