How to Generate SQL Command Schemas for the CData BizTalk Adapter for SQL Analysis Services

The CData BizTalk Adapter makes it easy to process SQL Analysis Services data in BizTalk by returning the data as XML. You can use this data in a BizTalk orchestration by creating an XML schema file for the table you want to access in BizTalk.

This article will show how to generate a schema to process SQL Analysis Services data retrieved using the CData BizTalk Adapter. You will generate a schema for a SELECT command.

You can use the CData BizTalk Adapter for SQL Analysis Services to execute standard SQL commands to SQL Analysis Services. You can follow this guide to execute SELECT, INSERT, UPDATE, and DELETE commands.

Add the Adapter for SQL Analysis Services to Your Project

Follow the steps below to add the adapter to a BizTalk Server project.

  1. If you have not already done so, create a new BizTalk Server project in Visual Studio.
  2. Right-click on the project in the Solution Explorer and click Add -> Add Generated Items.
  3. Select Add Adapter Metadata in the resulting dialog box.
  4. In the resulting Add Adapter wizard, select the adapter from the list.
  5. In the Port menu, leave the selection blank. You can also select a receive location or send port that has the adapter configured as its transport type.

Generate a Schema for an SQL Command

After you select the adapter in the Add Adapter wizard, the Schema wizard is displayed. Follow the steps below to configure connection properties and retrieve the metadata for the results of the command.

  1. In the Connection String page, enter authentication credentials and other connection properties, if you did not select an adapter that you have already configured in your BizTalk application. Below is a typical connection string:

    User=myuseraccount;Password=mypassword;URL=http://localhost/OLAP/msmdpump.dll;

    接続するには、Url プロパティを有効なSQL Server Analysis Services エンドポイントに設定して認証を提供します。XMLA アクセスを使用して、HTTP 経由でホストされているSQL Server Analysis Services インスタンスに接続できます。 Microsoft ドキュメント configure HTTP access tを参照してSQL Server Analysis Services に接続してください。

    SQL をSQL Server Analysis Services に実行するには、Analysis Services データの取得 を参照してください。接続ごとにメタデータを取得する代わりに、CacheLocation を設定できます。

    • HTTP 認証

      AuthScheme を"Basic" または"Digest" に設定してUser とPassword を設定します。CustomHeaders に他の認証値を指定します。

    • Windows (NTLM)

      Windows のUser とPassword を設定して、AuthScheme をNTLM に設定します。

    • Kerberos およびKerberos Delegation

      Kerberos を認証するには、AuthScheme をNEGOTIATE に設定します。Kerberos 委任を使うには、AuthScheme をKERBEROSDELEGATION に設定します。必要があれば、User、Password およびKerberosSPN を設定します。デフォルトでは、本製品 は指定されたUrl でSPN と通信しようと試みます。

    • SSL/TLS:

      デフォルトでは、本製品 はサーバーの証明書をシステムの信頼できる証明書ストアと照合してSSL/TLS のネゴシエーションを試みます。別の証明書を指定するには、利用可能なフォーマットについてSSLServerCert プロパティを参照してください。

    You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.

    See the Getting Started section of the CData documentation, under Retrieving Analysis Services Data, to execute SQL-92 queries to the cubes.

  2. In the General Options section on the next page, Schema Information, select Send Port or Receive Location, depending on the adapter configuration.
  3. If you want to generate the schema for the entire result set, select the Single Message option in the Message Mode menu. If you want to generate one schema for each row in the result set, select the Message Per Row option and confirm that the root element of the message is 'row'.
  4. In the Command Type menu, select SQL Command.
  5. In the SQL Command Text box on the Statement Information page, enter an SQL command. (If you have configured a receive location or send port, the SQL command you configured is entered in the box.) This example uses the query below:

    SELECT * FROM Adventure_Works

  6. Confirm the settings in the summary displayed by the wizard and click Finish to generate the schema.xsd file.
