Question

大家好我尝试使用下面的查询写入文件。这是一个关于30声明的动态调用。第一次调用是好的我写了一行（结果变成了变量，这一次写入文件）。从第二轮开始我得到了这个错误： “父标记ID 1不在开放标记中。FOR XML EXPLICIT要求首先打开父标记。检查结果集的顺序”。

我不理解，因为我可以解决。

SELECT DISTINCT
    1 as Tag,
    NULL as Parent,
    NULL AS [Products!1], -- empty root element
    NULL AS [Product!2!ExternalId!element],
    NULL AS [Product!2!Name!element],
    NULL AS [Product!2!Description!element],
    NULL AS [Product!2!BrandExternalId!element],
    NULL AS [Product!2!CategoryExternalId!element],
    NULL AS [Product!2!ProductPageUrl!cdata],
    NULL AS [Product!2!ImageUrl!cdata],
    NULL AS [Product!2!],
    NULL AS [Product!2!]
UNION ALL
SELECT 
    2 AS Tag,
    1 AS Parent,
    NULL,
    ExternalId,  
    [Name],
    [Description],
    REPLACE(BrandExternalId,'/','_') as BrandExternalId,
    IDnodo as CategoryExternalId,
    ProductPageUrl,
    ImageUrl,   
    (
    SELECT ManufacturerPartNumber
    FOR XML PATH('ManufacturerPartNumbers'),TYPE
    ),
    (SELECT b.EAN  
     FROM Cestino.acap.Bazaar_Servizio_01  b 
     WHERE (ff.ExternalId = b.codart)  
    AND PATINDEX('%[^0-9]%', b.EAN) = 0
    AND CHARINDEX('.', b.EAN) = 0
     AND LEN(b.EAN) = 13
     AND isNumeric(b.EAN) = 1
     FOR XML PATH(''), ROOT('EANs'), TYPE)
FROM Cestino.acap.Bazaar_Servizio_00  ff with (nolock) 
--WHERE ExternalId = 100212694
ORDER BY 3, Parent
OFFSET ((2 - 1) * 10000) ROWS
FETCH NEXT 1000 ROWS ONLY
FOR XML EXPLICIT

尝试一下：

SELECT DISTINCT
    1 as Tag,
    NULL as Parent,
    NULL AS [Products!1], -- empty root element
    NULL AS [Product!2!ExternalId!element],
    NULL AS [Product!2!Name!element],
    NULL AS [Product!2!Description!element],
    NULL AS [Product!2!BrandExternalId!element],
    NULL AS [Product!2!CategoryExternalId!element],
    NULL AS [Product!2!ProductPageUrl!cdata],
    NULL AS [Product!2!ImageUrl!cdata],
    NULL AS [Product!2!],
    NULL AS [Product!2!]
UNION ALL
SELECT 
    2 AS Tag,
    1 AS Parent,
    NULL,
    ExternalId,  
    [Name],
    [Description],
    REPLACE(BrandExternalId,'/','_') as BrandExternalId,
    IDnodo as CategoryExternalId,
    ProductPageUrl,
    ImageUrl,   
    (
    SELECT ManufacturerPartNumber
    FOR XML PATH('ManufacturerPartNumbers'),TYPE
    ),
    (SELECT b.EAN  
     FROM Cestino.acap.Bazaar_Servizio_01  b 
     WHERE (ff.ExternalId = b.codart)  
    AND PATINDEX('%[^0-9]%', b.EAN) = 0
    AND CHARINDEX('.', b.EAN) = 0
     AND LEN(b.EAN) = 13
     AND isNumeric(b.EAN) = 1
     FOR XML PATH(''), ROOT('EANs'), TYPE)
FROM Cestino.acap.Bazaar_Servizio_00  ff with (nolock) 
--WHERE ExternalId = 100212694
ORDER BY 3, Parent
OFFSET ((2 - 1) * 10000) ROWS
FETCH NEXT 1000 ROWS ONLY
Order by Tag
FOR XML EXPLICIT

父标记ID 1不在打开标记中。 FOR XML EXPLICIT要求首先打开父标记。检查结果集的顺序
