XMLデータをテーブルにインポートするときにNULL値を取得する

Question

XMLファイルをSQL Serverのテーブルにインポートしようとしています。私はテーブルにnull値を得ることになった

Declare @x xml 

Select @x = p 
      from OpenRowSet(BULK 'C:\Users\sivat\OneDrive\Projects\SQL Server  Projects\Books.xml',SINGLE_BLOB) as BOOKS(p) 

Declare @hdoc int 

exec sp_xml_preparedocument @hdoc output,@x 

IF OBJECT_ID('BOOKS') IS NOT NULL 
    DROP Table BOOKS 

select * 
into BOOKS 
from openxml(@hdoc,'/catalog/book',2) 
with 
( Author nvarchar(150), 
    Title nvarchar(150), 
    Genre nvarchar(150), 
    Price float, 
    Publish_Date Date, 
    Description nvarchar(200)) 
exec sp_xml_removedocument @hdoc 
select * from BOOKS 

を私は何をする必要があります

何を修正..：ここ

は、私が書いたコードはありますか？ここで

は、元のXMLファイルです：ビルトインのXQuery方法ではなく不格好、メモリリークするOPENXMLものよりも、私はネイティブを使用することを好むだろう

Answer 1

.....

この唯一ディスプレイ値、もちろん

DECLARE @x XML 

SELECT @x = p FROM OpenRowSet(BULK 'C:\Users\sivat\OneDrive\Projects\SQL Server Projects\Books.xml',SINGLE_BLOB) as BOOKS(p) 

SELECT 
    Author = xc.value('(author)[1]', 'nvarchar(150)'), 
    Title = xc.value('(title)[1]', 'nvarchar(150)'), 
    Genre = xc.value('(genre)[1]', 'nvarchar(150)'), 
    Price = xc.value('(price)[1]', 'decimal(15,2)'), 
    Publish_Date = xc.value('(publish_date)[1]', 'date'), 
    Description = xc.value('(genre)[1]', 'nvarchar(200)') 
FROM 
    @x.nodes('/catalog/book') AS XT(XC) 

- しかし、あなたは簡単に、最終的に置き換えることができます。このコードを試してみてください

INSERT INTO dbo.Books(Author, Title, Genre, Price, Publish_Date, Description) 
    SELECT 
     Author = xc.value('(author)[1]', 'nvarchar(150)'), 
     Title = xc.value('(title)[1]', 'nvarchar(150)'), 
     Genre = xc.value('(genre)[1]', 'nvarchar(150)'), 
     Price = xc.value('(price)[1]', 'decimal(15,2)'), 
     Publish_Date = xc.value('(publish_date)[1]', 'date'), 
     Description = xc.value('(genre)[1]', 'nvarchar(200)') 
    FROM 
     @x.nodes('/catalog/book') AS XT(XC) 

と（この文を実行する前に存在している必要があり）表dbo.Booksにデータを挿入します。これでSELECT。

も注意してください。私は（丸め誤差に悪名高い感受性がある）floatからPriceのためのデータ型を変更し、あなたが+1 :-)秒で私を倒す
