如何使用MS SQL中的名稱空間驗證XML存儲過程參數與XSD？

Question

我有一個數據集People，我希望能夠將該集合插入到我的表中，但驗證輸入XML匹配我創建的XML SCHEMA COLLECTION。在我的代碼不使用名稱空間的簡單版本中，我能夠完成這個任務，但我希望能夠使用用戶定義的數據類型以及名稱空間來完成此任務。當我嘗試用下面的代碼，我得到消息2260，級別16，狀態1，過程sp_InsertPerson，行16 的XQuery [節點（）]：沒有命名的元素「人」

我已經嘗試了事情的數量，並沒有能夠找出如何做到這一點。下面是創建存儲過程的代碼：

USE [A_IndexingTest] 
GO 
CREATE PROCEDURE [dbo].[sp_InsertPerson] 
(
    @xmlData XML (dbo.PersonSchemaCollection) 
) 
AS 
BEGIN 

INSERT INTO dbo.Person 
    (LastName, FirstName, Gender, DateOfBirth, IsFriendly) 
SELECT 
    person.field.value('(FirstName)[1]', 'nvarchar(100)'), 
    person.field.value('(LastName)[1]', 'nvarchar(100)'), 
    person.field.value('(Gender)[1]', 'char(1)'), 
    person.field.value('(DateOfBirth)[1]', 'datetime'), 
    person.field.value('(IsFriendly)[1]', 'bit') 
FROM @xmlData.nodes('/People/Person') AS person(field) 

SELECT CAST(SCOPE_IDENTITY() as int) 
END 
GO 

以及創建XSD：因爲我用它似乎我需要引用命名空間當存儲的過程得到一個targetNamespace

USE [A_IndexingTest] 
GO 
CREATE XML SCHEMA COLLECTION [dbo].[PersonSchemaCollection] AS 
N' 
    <?xml version="1.0"?> 
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    targetNamespace="http://example.org/People" 
    xmlns:tns="http://example.org/People"> 

    <xs:simpleType name="firstName"> 
     <xs:restriction base="xs:string"> 
     <xs:minLength value="1" /> 
     <xs:maxLength value="100" /> 
     </xs:restriction> 
    </xs:simpleType> 

    <xs:simpleType name="lastName"> 
     <xs:restriction base="xs:string"> 
     <xs:minLength value="1" /> 
     <xs:maxLength value="100" /> 
     </xs:restriction> 
    </xs:simpleType> 

    <xs:simpleType name="gender"> 
     <xs:restriction base="xs:string"> 
     <xs:minLength value="1" /> 
     <xs:maxLength value="1" /> 
     </xs:restriction> 
    </xs:simpleType> 

    <xs:simpleType name="dateOfBirth"> 
     <xs:restriction base="xs:date"> 
     </xs:restriction> 
    </xs:simpleType> 

    <xs:simpleType name="isFriendly"> 
     <xs:restriction base="xs:boolean">   
     </xs:restriction> 
    </xs:simpleType> 

    <xs:element name="People"> 
     <xs:complexType> 
     <xs:sequence> 
      <xs:element maxOccurs="unbounded" name="Person"> 
      <xs:complexType> 
       <xs:sequence> 
       <xs:element name="FirstName" type="tns:firstName" minOccurs="1" maxOccurs="1" /> 
       <xs:element name="LastName" type="tns:lastName" minOccurs="1" maxOccurs="1" /> 
       <xs:element name="Gender" type="tns:gender" minOccurs="1" maxOccurs="1" /> 
       <xs:element name="DateOfBirth" type="tns:dateOfBirth" minOccurs="1" maxOccurs="1" /> 
       <xs:element name="IsFriendly" type="tns:isFriendly" minOccurs="1" maxOccurs="1" /> 
       </xs:sequence> 
      </xs:complexType> 
      </xs:element> 
     </xs:sequence> 
     </xs:complexType> 
    </xs:element> 
</xs:schema>'

創建。

CREATE PROCEDURE [dbo].[sp_InsertPerson] (
    @xmlData XML (dbo.PersonSchemaCollection) 
) 
AS 
BEGIN 

-- this is the part that I was missing 
WITH XMLNAMESPACES('http://example.org/People' as tns) 

INSERT INTO dbo.Person 
    (LastName, FirstName, Gender, DateOfBirth, IsFriendly) 
SELECT 

    -- additionally note the tns prefix for all of the fields and nodes 
    person.field.value('(tns:FirstName)[1]', 'nvarchar(100)'), 
    person.field.value('(tns:LastName)[1]', 'nvarchar(100)'), 
    person.field.value('(tns:Gender)[1]', 'char(1)'), 
    person.field.value('(tns:DateOfBirth)[1]', 'datetime'), 
    person.field.value('(tns:IsFriendly)[1]', 'bit') 
FROM @xmlData.nodes('/tns:People/tns:Person') AS person(field) 

SELECT CAST(SCOPE_IDENTITY() as int) 
END 
GO
