一个专门有关SQL Server的中文博客. 主要面向中国的SQL Server用户. 侧重于介绍的SQL Server 2005在XML方面的功能．也会尽力解答其他SQL相关问题.

TechEd 2008: 演示SQL脚本 for "全面整合的SQL Server 2008 全文本搜索"

下面的演示在两个演讲中都用到了。因为不能把所用文本数据直接给出，我提供了链接。希望能为大家学习和了解SQL2008 fulltext有帮助。

吉姆•格雷失踪了!

“吉姆·格雷失踪了!”

当我看到同事转发来的email的题目时,我真有点不相信自己的眼睛. 读完了那篇Mercury News的报道, 经过了初期震惊后的理性告诉我: 这是因为我不愿意相信.

大部分SQL Server team 的人都是那种只信科学不信神的 hard core geeks. 但我想很多人可能都象我一样,在心里暗中祈祷奇迹发生. 都是在RDBMS这个圈子里”混”的人. 这里有太多吉姆的朋友,前同事, 和粉丝. 另外作为微软的一员,我们知道公司失去了唯一的图灵奖获得者L.

吉姆是分布式计算技术(distributed computing )”先知级” 鼓吹者(区别于事后诸葛亮们). 这是一篇他在1985年写的文章: http://research.microsoft.com/~gray/papers/TandemTR85.4_AnApproachToDecentralizedComputerSystems.pdf. 懂计算机且置身于Web2.0时代的人读了这篇东西,会明白为什么他得计算机领域中的”诺贝尔”奖.

我有幸和吉姆·格雷有过一次近距离的接触. 2005年初,我们SQL 2005 XML项目组请他来review 我们做的XML features. 我们五,六个人为他演示和讲解了SQL 2005的 XML Datatype, XML Index, XML Schema Collection, XQuery, FOR XML等功能. 他给我们提了一些有关应用方面的建议. 给我留下很深印象的是: 这位六十岁左右的老人敏捷的思路和对新东西无止境的好奇心. 我从小在研究大院长大. 来美国前也在研究单位工作过. 到微软后更是接触了太多聪明绝顶的中国人. 坦率的讲,我就从来没有碰见过他这样功成名就后的依然科学家的科学家. 我到是见识过很多开公司发财的前科学家,热衷于政治的前科学家,当了”德育导师”的前科学家,当然更多的是当了VP 或各种 % 长的前科学家. 让我真佩服钱钟书在围城里总结的:”外国科学进步,中国科学家进爵”L.

当我回家对太太提及吉姆出海失踪一事时, 她评论说”有钱玩这种帆船,飞机有什么好? 约翰.丹佛和小肯尼迪就是玩飞机死的. 这又有一个玩船的.”. 太太说得一点没错. 但我还是挺羡慕吉姆的. 人都有一死. 如果能干着自己最享受的事走向终点,不亦乐呼!

Have Fun, Jim!

SQL2005对XSD的支持更丰富了数据建模的方法

在SQL2005中,有一个新的顶级对象(top level object)被加入: XML架构集合(XML Schema Collection). 它提供给用户贮存XSD (XML Schema Definition)并用之验证特定XML格式的能力. 更重要的是,它提供了一种可更丰富描述数据模型的方法

举例:
create xml schema collection xsdPurchaseOrder as
N'<schema targetNamespace="http://www.example.com/IPO" xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:ipo="http://www.example.com/IPO" elementFormDefault="qualified">

<annotation>
<documentation xml:lang="zh-Hans">
为国际订货单据定义的各种地址格式
Copyright 2000 Example.com. All rights reserved.
</documentation>
</annotation>

<complexType name="Address">
   <sequence>
     <element name="name" type="string"/>
     <element name="street" type="string"/>
     <element name="city" type="string"/>
   </sequence>
</complexType>

<complexType name="USAddress">
   <complexContent>
     <extension base="ipo:Address">
       <sequence>
         <element name="state" type="ipo:USState"/>
         <element name="zip" type="positiveInteger"/>
       </sequence>
     </extension>
   </complexContent>
</complexType>

<complexType name="CNAddress">
   <complexContent>
     <extension base="ipo:Address">
       <sequence>
         <element name="省" type="ipo:CNProvince"/>
     <element name="邮编" type="positiveInteger"/>
    </sequence>
</extension>
   </complexContent>
</complexType>

<simpleType name="USState">
   <restriction base="string">
     <enumeration value="AK"/>
     <enumeration value="AL"/>
     <enumeration value="AR"/>
     
     <enumeration value="PA"/>
   </restriction>
</simpleType>

<simpleType name="CNProvince">
   <restriction base="string">
     <enumeration value="湖南"/>
     <enumeration value="湖北"/>
     <enumeration value="辽宁"/>
     
     <enumeration value="江苏"/>
   </restriction>
</simpleType>

<element name="purchaseOrder" type="ipo:PurchaseOrderType"/>

<complexType name="PurchaseOrderType">
<sequence>
   <element name="shipTo" type="ipo:Address"/>
   <element name="billTo" type="ipo:Address"/>
   <element ref="ipo:comment" minOccurs="0"/>
   
   <element name="items" type="string"/>
</sequence>
<attribute name="orderDate" type="date"/>
</complexType>
</schema>'
go

针对上述格式,我们可将下面的订单存入数据库中带有此架构集合的XML列中. SQL Server将对要存入的XML进行验证(validate),确保数据的格式. 这实际上就提供了新的数据建模方法.

create table tbl_Orders( id int, PurchaseOrder xml(xsdPurchaseOrder) )
insert tbl_Orders value( 1,
N'<purchaseOrder xmlns="http://www.example.com/IPO" orderDate="2005-10-30">
<shipTo>
<name>兴业公司</name>
   <street>兴业路十五号</street>
   <city>无锡</city>
   <省>江苏</省>
   <邮编>12345</邮编>
</shipTo>
<billTo>
<name>ABC Corp</name>
<street>1710 Madison Ave.</street>
<city>Jamesville</city>
<state>PA</state>
<zip>98000</zip>
</billTo>
<comment>ABC Corp 购买一批组件并直接寄送兴业公司组装</comment>
<items>541045系列组件</items>
</purchaseOrder>' )
go

在上述例子中,我们定义了不同格式的地址并用xs:enumeration为<省>和<state>约束了数值范围.

XML提供新的数据建模方法

当W3C的专家们刚开始筹划XML(eXtensible Markup Language) 的标准时，他们的目的是发明一种比HTML更好得标识语言：“Originally designed to meet the challenges of large-scale electronic publishing …”(http://www.w3.org/XML/)。没有想到最终结果却是为互联网上的数据传输提供了一个好办法。

</OrderDetail>

</OrderDetail>

</OrderDetail>

</Order>

</OrderDetail>

</Order>

</Customer>

上面的XML非常自然的表现出客户、订单、订单细节、和产品之间的关系。这是因为在XML中，数据和元数据(Metadata)是结合在一起的。这个特点使XML具有自我解释的能力。这正是互联网数据传输所需耍的。

在SQL2000中，FORXML提供了非常简单快捷的方法将任何SELECT的结果变成任何的格式XML，OPENXML则可将任何的格式XML变成SELECT的结果。再加上SQLXML的API，SQL2000成为了第一个可直接面向互联网的关系性数据库。

但XML可以解决更多关系性数据库解决不了(or不好)的问题,特别是在数据模型(data modeling)方面:

半结构性semi-structure
分层hierarchical
保留顺序order preservation
非结构性un-structure

通过下面的例子我们可以看到XML如何解决上述问题1,2,3.

一个描述家族谱系的XML:

<?xml version="1.0" encoding="utf-8"?>

<成员名="李一" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd">

<成员名="李二一" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd">

<成员名="李三一" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd">

...

</成员>

<成员名="李三三" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd">

...

</成员>

<成员名="李三四" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd">

<成员名="李四四" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd"/>

<成员名="李四六" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd">

<成员名="李五一" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd" 妻="李张氏">

<成员名="李六一" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd" 妻="李王氏">

<成员名="李七一" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd" 妻="李赵氏">

<成员名="李八一" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd" 妻="李张氏">

<成员名="李九一" 生日="yyyy-mm-dd" 妻="李胡氏" 职业="教师">

<成员名="李十一" 生日="yyyy-mm-dd" 职业="学生"/>

</成员>

<成员名="李四七" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd"/>

</成员>

<成员名="李二二" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd"/>

<成员名="李二三" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd">

<成员名="李三二" 生日="yyyy-mm-dd" 冥日="yyyy-mm-dd">

...

</成员>

从上面数据中，你可看出下述特点:

直观表现层次(hierarchical)。如要找出李五一所有直系子孙，只需执行查询 //成员[@名="李五一"]
保留顺序(order preservation)。如要找出李二一第三个孩子的名字，只需执行查询 //成员[@名="李二一"]/成员[3]/@名
支持半结构性(semi-structure)数据。从李五一开始，增加了关于”妻”的新属性。从李九一开始，增加了关于”职业”的新属性。这些增加都不对已有数据产生影响。

SQL2005通过对XML的内置(native support)和对XQuery的支持实现了上述功能.

My first blog post!

To: 中国的SQL Server用户，

今年是我第三次参加微软中国技术教育大会(MS China TechEd 2005)．每一次我都发现苦于时间太短,我

无法讲完所有我想讲的内容
无法回答所有听众的问题
无法很好解释需要用数据和程序来说明的问题
无法让所有听众分享对某个好问题的回答

当公司建议我们开设自己的博客,从而增加我们和用户之间的交流时,我突然发现了解决这些问题的方法:

开一个专门有关SQL Server的中文博客.

从1994年第一次上alt.chinese.text以来我在互联网上就只潜水,不上浮,最大的原因就是对输入中文的不自信. 不过这次我打算试试[:)]

先登一下我的简历:
刘劲浩: 1992就读于Stevens Institute of Technology, New Jersey并获计算机硕士学位. 1993年至1996年, 作为软件开发工程师就职于Princeton Softech. 参与设计和开发Relational Tools, 一个可以运行在DB2, Oracle, Sybase, XDB等数据库平台上的关系性数据管理工具. 96至1997,作为独立IT顾问商就职于Prudential Insurance. 参与设计和开发基于Oracle 数据库平台的中间件. 1997至今就职于微软SQL Server事业部. 参与设计和测试SQL Server查询处理器, SQLXML和XML Database等功能．

我将陆续写或翻译一些介绍SQL Server 2005新功能的文章. 当然是从我最熟悉的XML功能讲起. 也欢迎大家给我提要求,告诉我你最想知道什么.

希望大家"顶"我[:)]
