Sql server 如何在SQLServer2008中对XML列执行OrderBY

我正在为下面XML的dbName属性中指定的列创建一个逗号分隔的值。现在我想根据Position属性连接这些列

DECLARE @varXML AS XML  = 
         '<gridFormat>                   
              <column property="FacilityInternalID" dbName="Pname" HeaderText="TAT Health" IsVisible="1" Position="1" />
              <column property="FacilityInternalID" dbName="Priority" HeaderText="Priority" IsVisible="1" Position="2" />
              <column property="FacilityInternalID" dbName="JobID" HeaderText="Job Number" IsVisible="1" Position="3" />
              <column property="FacilityInternalID" dbName="Status" HeaderText="Status" IsVisible="1" Position="6" />
              <column property="FacilityInternalID" dbName="name" HeaderText="Customer" IsVisible="1" Position="4" />
              <column property="FacilityInternalID" dbName="sname" HeaderText="Facility " IsVisible="1" Position="5" />                  
         </gridFormat>'
        PRINT @varXML

结果应该是

select Pname,Priority,JobID,name,sname,status FROM JobListingDetails.

请提供帮助。

有关不使用光标进行字符串连接的酷方法，请参阅

它位于“使用基于集合的方法替换光标”部分下。

这应该可以：

注意，您需要读取dbName属性

DECLARE @varXML AS XML  = 
         '<gridFormat>                   
              <column property="FacilityInternalID" dbName="Pname" HeaderText="TAT Health" IsVisible="1" Position="1" />
              <column property="FacilityInternalID" dbName="Priority" HeaderText="Priority" IsVisible="1" Position="2" />
              <column property="FacilityInternalID" dbName="JobID" HeaderText="Job Number" IsVisible="1" Position="3" />
              <column property="FacilityInternalID" dbName="Status" HeaderText="Status" IsVisible="1" Position="6" />
              <column property="FacilityInternalID" dbName="name" HeaderText="Customer" IsVisible="1" Position="4" />
              <column property="FacilityInternalID" dbName="sname" HeaderText="Facility " IsVisible="1" Position="5" />                  
         </gridFormat>'
        PRINT @varXML

declare @ColumnsToDisplay varchar(max)

DECLARE @varXML AS XML
set @varxml  = 
         '<gridFormat>                   
              <column property="FacilityInternalID" dbName="Pname" HeaderText="TAT Health" IsVisible="1" Position="1" />
              <column property="FacilityInternalID" dbName="Priority" HeaderText="Priority" IsVisible="1" Position="2" />
              <column property="FacilityInternalID" dbName="JobID" HeaderText="Job Number" IsVisible="1" Position="3" />
              <column property="FacilityInternalID" dbName="Status" HeaderText="Status" IsVisible="1" Position="6" />
              <column property="FacilityInternalID" dbName="name" HeaderText="Customer" IsVisible="1" Position="4" />
              <column property="FacilityInternalID" dbName="sname" HeaderText="Facility " IsVisible="1" Position="5" />                  
         </gridFormat>'

SELECT  @ColumnsToDisplay = COALESCE(@ColumnsToDisplay + ',', '') + dbName
FROM
(
    SELECT    row.value('@dbName','varchar(200)')  AS dbName, row.value('@Position','int') as pos
    FROM      @varXML.nodes('gridFormat/column')
    AS d ( row )
) csv
order by pos
select 'SELECT ' + @ColumnsToDisplay + ' FROM JobListingDetails' 

这应该起作用：
