追加聲明XML文件

通過用BCP調用proc用作追加聲明XML文件

SET @SQL= 'bcp "exec dbo.proc" queryout '+ @FileName +' -w -r -t -Sdd\SQL2005 -T '

創建XML列於數據庫的數據（下面產生PROC）一切都很好=>根據需要創建XML。現在的任務就是聲明添加到這個XML（<?xml version="1.0" ?>）

怎麼可以這樣無論是在下面PROC或concating XML與其他文件（包含聲明）來實現

SELECT (SELECT TOP 1 
        ShiftDate AS "ShiftDate", 
        Shift AS "Shift" 
      FROM  [TableName] 
     FOR 
      XML PATH(''), 
       TYPE 
     ), 
     (SELECT EquipmentId AS "WasheryProductionDetails/EquipmentCode", 
        'n/a' AS "WasheryProductionDetails/ActivityCode", 
        'n/a' AS "WasheryProductionDetails/ReasonCode", 
        Parentmaterial AS "WasheryProductionDetails/WasheryFeed/MaterialCode", 
        ParentStockpile AS "WasheryProductionDetails/WasheryFeed/ROMStockpileCode", 
        CAST(ParentTonnes AS DECIMAL(18, 4)) AS "WasheryProductionDetails/WasheryFeed/FeedTonnes", 
        ChildMaterial AS "WasheryProductionDetails/WasheryOutput/MaterialCode", 
        ChildStockpile AS "WasheryProductionDetails/WasheryOutput/ProductStockpileCode", 
        CAST(ChildTonnes AS DECIMAL(18, 4)) AS "WasheryProductionDetails/WasheryOutput/ProductTonnes" 
      FROM  [TableName] 
     FOR 
      XML PATH(''), 
       TYPE 
     ) 
FOR  XML PATH(''), 
      ROOT('WasheryProduction')

爲什麼？它問一個TSQL問題？ RMDUSSA：你可以用更多的信息來重新解釋你的錯誤信息。 – 2009-04-28 08:40:18

This page建議您需要對聲明進行硬編碼：

SELECT 

'<?xml version="1.0" ?>' 

+ 
SELECT (SELECT TOP 1 
... rest of your code goes here...

編輯：更改了「UNION ALL」（whic h）顯示爲「+」（均取自鏈接頁面）。

對不起，我以前試過，錯誤是所有使用UNION，INTERSECT或EXCEPT操作符組合的查詢必須在其目標列表中具有相同數量的表達式。謝謝 – rmdussa 2009-04-29 04:29:32

Declare @SQL varchar(8000) 
Declare @xml xml 
Declare @strXML as varchar(max) 

set @xml = (select * from <tableName> for xml path('')) 
set @strXML='< ? xml version = "1.0" ? >' + convert(varchar(max), @xml) 

select @strXML 

set @SQL ='bcp "select '''[email protected]+'''" QueryOut "C:\xmlFile.xml" -r -w -t -T -S ' 

Exec master..xp_cmdshell @SQL
