您好我试图从XML文件中获取一些信息到我的MSSQL数据库中，任何人都可以发现错误。
这是我的sql代码（现在用循环修复，遍历整个目录和错误陷阱）
使用mydb
IF OBJECT_ID('mydb..tempList') IS NOT NULL
DROP TABLE tempList
CREATE TABLE tempList ([FileName] VARCHAR(500))
--plain vanilla dos dir command with /B switch (bare format)
INSERT INTO tempList
EXEC MASTER..XP_CMDSHELL 'dir C:\Data\icecat\xmls /B'
--delete the null values
DELETE tempList WHERE [FileName] IS NULL
-- Delete all the files that don't have xml extension
DELETE tempList WHERE [FileName] NOT LIKE '%.xml'
--this will be used to loop over the table
alter table tempList add id int identity
go
truncate table dbo.XMLImportRelated --in case you want to rerun just this codeblock
DECLARE @Directory varchar(100)
SELECT @Directory = 'C:\Data\icecat\xmls\'
DECLARE @FileExist int
DECLARE @FileName varchar(500),@DeleteCommand varchar(1000),@FullFileName varchar(500), @SQLFullFileName varchar(500)
DECLARE @ProductID int
DECLARE @RelatedID int
- 这样我们就可以知道循环持续多长时间了 DECLARE @LoopID int，@ MaxID int SELECT @LoopID = min（id），@ MaxID = max（ID） 来自tempList
WHILE @LoopID <= @MaxID
BEGIN
SELECT @FileNAme = filename
FROM tempList
WHERE id = @LoopID
SELECT @FullFileName = @Directory + @FileName
EXEC xp_fileexist @FullFileName , @FileExist output
IF @FileExist =1 --sanity check in case some evil person removed the file
BEGIN
DECLARE @x XML, @sql NVARCHAR(MAX);
BEGIN TRY
SELECT @sql = N'SELECT @X = CONVERT(xml,[ICECAT-interface],2)
FROM OPENROWSET(BULK ''' + @FullFileName + ''' ,SINGLE_BLOB)
---------------------^^ escaped quotes are important
AS Import([ICECAT-interface]);';
EXEC sp_executesql @sql, N'@x XML OUTPUT', @x OUTPUT;
END TRY
BEGIN CATCH
PRINT 'Error'
END CATCH
INSERT XMLImportRelated ([ProductID],RelatedID)
select P1.X.value('@ID', 'int') as ProductID,
P2.X.value('@ID', 'int') as RelatedID
from @X.nodes('/ICECAT-interface/Product') as P1(X)
cross apply P1.X.nodes('ProductRelated') as PR(X)
cross apply PR.X.nodes('Product') as P2(X)
-- SET @DeleteCommand = 'del ' + @Directory + @FileName
END
SELECT @LoopID = min(id)
FROM tempList
WHERE id > @LoopID
END
这里是xml我尝试使用

谢谢你们，我一直都是空的，所以它的东西很小，但我看到它整个上午我都疯了， 约翰。
答案 0 :(得分：0)
在您提供的XML中，/ICECAT-interface/Product/ProductRelated中有四个属性，path不是其中之一。
尝试：
SELECT
Product.value('@ID', 'int'),
Product.value('@Category_ID','int'),
Product.value('@Reversed','bit'),
Product.value('@Preferred','bit')
FROM ...
如果您想从/ICECAT-interface/Product/ProductRelated/Product中选择属性，则需要将nodes子句更改为包含Product，并指定字段列表中使用的属性。
要从ProductRelated和Product获取值，您应该使用cross apply。
select PR.X.value('@ID', 'int') as ProductRelatedID,
PR.X.value('@Category_ID','int') as Category,
PR.X.value('@Reversed','bit') as Reversed,
PR.X.value('@Preferred','bit') as Preferred,
P.X.value('@ID', 'int') as ProductID,
P.X.value('@Prod_id', 'nvarchar(500)') as Prod_id,
P.X.value('@ThumbPic', 'nvarchar(500)') as ThumbPic,
P.X.value('@Name', 'nvarchar(500)') as Name
from @X.nodes('/ICECAT-interface/Product/ProductRelated') as PR(X)
cross apply PR.X.nodes('Product') as P(X)
<强>更新
select P1.X.value('@ID', 'int') as ProductID,
PR.X.value('@ID', 'int') as ProductRelatedID,
PR.X.value('@Category_ID','int') as Category,
PR.X.value('@Reversed','bit') as Reversed,
PR.X.value('@Preferred','bit') as Preferred,
P2.X.value('@ID', 'int') as ProductID,
P2.X.value('@Prod_id', 'nvarchar(500)') as Prod_id,
P2.X.value('@ThumbPic', 'nvarchar(500)') as ThumbPic,
P2.X.value('@Name', 'nvarchar(500)') as Name
from @X.nodes('/ICECAT-interface/Product') as P1(X)
cross apply P1.X.nodes('ProductRelated') as PR(X)
cross apply PR.X.nodes('Product') as P2(X)
结果：
ProductID ProductRelatedID Category Reversed Preferred ProductID Prod_id ThumbPic Name
