XmlFileをSql-serverにロードする

Question

XmlFileをSql-Serverにロードしようとしていますが、sqlbulkcopyを使用しますが、XmlFileをデータセットに変換する方法がわかりません。 。ここに私のXmlFileとありがとうございます。

Answer 1

最後に解決策はMS-SQLサーバーにXmlFileを読み込むことです。

cmd.CommandText = "Insert into Table_fileXml(xml) SELECT CONVERT(XML, BulkColumn) AS BulkColumn From OPENROWSET(BULK 'd:\\XmlFile.xml', SINGLE_BLOB) AS X"; 

cmd.ExecuteNonQuery(); 

cmd.Parameters.Clear(); 

そして最後に、私のファイルXMLFILEが私のMS-SQL Serverデータベースに挿入されることの後に、ストアドプロシージャを実行しますトリガーの作成：

USE [DatabaseName] 
GO 

SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 

ALTER TRIGGER [dbo].[trigger1] 
ON [dbo].[Table_FileXml] 
AFTER INSERT 
AS 
BEGIN 
-- SET NOCOUNT ON added to prevent extra result sets from 
-- interfering with SELECT statements. 
SET NOCOUNT ON; 

-- Insert statements for trigger here 

DECLARE @xml xml 
SELECT top(1) @xml=xml FROM Table_fileXml ORDER BY id DESC 

SELECT data.value('created_time[1]','datetime') AS Data_CreatedTime 
    ,data.value('id[1]','nvarchar(max)') AS Data_Id 
    ,data.value('message[1]','nvarchar(max)') AS Data_Message 
    ,data.value('(from/id)[1]','nvarchar(50)') AS Data_From_Id 
    --more values here 
    ,data.value('(from/picture/data/url)[1]','nvarchar(max)') AS Data_From_Picture_URL 
    --more values here 

    ,comment.value('created_time[1]','datetime') AS Comment_CreatedTime 
    ,comment.value('id[1]','nvarchar(max)') AS Comment_Id 
    ,comment.value('message[1]','nvarchar(max)') AS Comment_Message 
    ,comment.value('(from/id)[1]','nvarchar(50)') AS Comment_From_Id 
    --more values here 
    ,comment.value('(from/picture/data/url)[1]','nvarchar(max)') AS Comment_From_Picture_URL 
    --more values here 

FROM @xml.nodes('/data/data') AS A(data) 
OUTER APPLY data.nodes('comments/data') AS B(comment) 
BEGIN 
DECLARE @xml2 xml 
SELECT top(1) @xml2=xml FROM Table_fileXml ORDER BY id DESC 
INSERT INTO Table_comment(from_id,from_pic,comment_message) 
SELECT DISTINCT comment.value('(from/id)[1]','nvarchar(50)') AS from_id, 
data.value('(from/picture/data/url)[1]','nvarchar(max)') AS from_pic, 
comment.value('message[1]','nvarchar(max)') AS comment_message 
FROM @xml2.nodes('/data/data') AS A(data) 
OUTER APPLY data.nodes('comments/data') AS B(comment) 
END 
END 

を私のC＃のプログラムでは、私は、このコマンドを使用しますそして結果は正しい。ストアドプロシージャを使用せずにトリガを使用するだけで、私のFileXMLの最後の行が得られます。そのため、私はトリガでストアドプロシージャを使用する必要があります。

貴重なご協力をいただき、ありがとうございました。 "Shnugo"、 "Martin Staufcik"、 "Abouzar"

Answer 2

あなたはSSISを使用するか、詳細については、SQL Serverでは、XMLを読むことができます： Importing and Processing data from XML files into SQL Server tables

sql-server-simple-example-of-reading-xml-file-using-t-sql

Answer 3

あなたはあなたの中にbyte[]プロパティにマップされますタイプvarbinary(max)のデータベース列を作成することができますドメインモデル。その後、XmlWriterを使用してXML文書をこの列に保管します。

public virtual void Save(
    XmlWriter w 
) 

Answer 4

次のクエリを実行すると、派生したテーブル内のXMLからすべてのデータを取得できます。

これを適切な表に挿入するのは簡単です。ヒント：

SELECT DISTINCT ... 
SELECT col1, col2 INTO #tbl ... 
INSERT INTO tbl SELECT col1, col2, ... 

そして、あなたは、フィッティングPARTITION BYでROW_NUMBER() OVER()のようなものを使用することができますIDの作成のための...
