第四章、XML集成

一、XML数据类型
XML数据类型是sql2005率先引入的。
1、定义XML数据的列

CREATE TABLE [Production].[ProductModel](
	[ProductModelID] [int] IDENTITY(1,1) NOT NULL,[Name] [dbo].[Name] NOT NULL,--[CatalogDescription]表中的格式
	[CatalogDescription] [xml](CONTENT [Production].[ProductDescriptionSchemaCollection]) NULL,[Instructions] [xml](CONTENT [Production].[ManuInstructionsSchemaCollection]) NULL,[rowguid] [uniqueidentifier] ROWGUIDCOL  NOT NULL,[ModifiedDate] [datetime] NOT NULL,CONSTRAINT [PK_ProductModel_ProductModelID] PRIMARY KEY CLUSTERED 
(
	[ProductModelID] ASC
)WITH (PAD_INDEX  = OFF,STATISTICS_norECOmpuTE  = OFF,IGnorE_DUP_KEY = OFF,ALLOW_ROW_LOCKS  = ON,ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
