在T-SQL中将XML数据转换为表格格式

Question

我想知道如何将XML层次结构数据转换为表格格式，并与SQL Server 2005 T-SQL（XPath / XQuery）中的其他关系数据库表联接。

例如，

<Employees>
  <Employee ID="001" Name="David" />
  <Employee ID="002" Name="Mike" />
  <Employee ID="003" Name="Alex" />
  <Employee ID="004" Name="Morris" />
</Employees>

至 ..

 ID       Name
  --------+--------
  001       David
  002       Mike
  003       Alex
  004       Morris

感谢您的建议。 :)

Answer 1

这是一种方法：

declare @x xml

set @x = '<Employees>
              <Employee ID="001" Name="David" />
              <Employee ID="002" Name="Mike" />
              <Employee ID="003" Name="Alex" />
              <Employee ID="004" Name="Morris" />
          </Employees>'

select emp.e.value('@ID','varchar(10)') as ID, 
       emp.e.value('@Name','varchar(10)') as Name
    from @x.nodes('Employees/Employee') as emp(e)

Answer 2

这与Joe先前提交的答案略有不同：

DECLARE @X xml
SET @X = '<Employees>
   <Employee ID="001" Name="David" />
   <Employee ID="002" Name="Mike" />
   <Employee ID="003" Name="Alex" />
   <Employee ID="004" Name="Morris" />
 </Employees>'

 SELECT
 [Employee].value('@ID','int')As ID,
 [Employee].value('@Name','varchar(10)') As Name
 FROM
 @x.nodes('/Employees/Employee') Employee([Employee])

这是在MSSQL Server 2008 R2中完成的

Answer 3

希望这对您有帮助

 declare @xml varchar(max)

 SET @xml = '<Employees>
  <Employee ID="001" Name="David" />
  <Employee ID="002" Name="Mike" />
  <Employee ID="003" Name="Alex" />
  <Employee ID="004" Name="Morris" />
</Employees>'

 Declare @documentHandler INT 

 EXEC sp_xml_preparedocument @documentHandler OUTPUT,@xml

 SELECT * 
 FROM OPENXML(@documentHandler,'/Employees/Employee')
       WITH (ID varchar(20),
             Name varchar(150))


 EXEC sp_xml_removedocument @documentHandler
