Verbinden von PolyBase mit Salesforce.com

PolyBase greift auf nicht-relationale und relationale Daten zu und kombiniert sie, alles innerhalb von SQL Server. Ab SQL Server 2019 unterstützt PolyBase Daten von Backends, für die ein ODBC-Treiber verfügbar ist.

Wir haben PolyBase mit unserem Salesforce-ODBC-Treiber ausprobiert, um Salesforce-Daten von SQL Server 2019 abzufragen.

Um loszulegen:

Installieren und lizenzieren Sie den Salesforce.com-ODBC-Treiber auf dem Computer, auf dem SQL Server installiert ist.
Sie benötigen Build 2.0.3 des Salesforce.com-ODBC-Treibers, der derzeit erhältlich ist, indem Sie sich an das Easysoft-Support-Team wenden ().
Stellen Sie in Microsoft SQL Server Management Studio eine Verbindung zu Ihrer PolyBase-fähigen SQL Server-Instanz her. Um zu überprüfen, ob PolyBase installiert ist, führen Sie diese Abfrage aus:
```
SELECT SERVERPROPERTY ('IsPolyBaseInstalled') AS IsPolyBaseInstalled;
```
Wenn PolyBase installiert ist, gibt diese Abfrage Folgendes zurück:
```
1
```

Außerdem müssen Sie sicherstellen, dass PolyBase aktiviert ist:

EXEC SP_CONFIGURE @CONFIGNAME = 'polybase enabled', @CONFIGVALUE = 1;
RECONFIGURE WITH OVERRIDE;

Wenn Sie dies noch nicht getan haben, starten Sie die PolyBase-Dienste (SQL Server PolyBase Engine, SQL Server PolyBase Data Movement) in der Windows-Dienstanwendung.

Erstellen Sie eine externe PolyBase-Datenquelle:

CREATE DATABASE PolyBaseDB

USE PolyBaseDB

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'p455w0rd';

CREATE DATABASE SCOPED CREDENTIAL PolyBaseSalesforce
WITH IDENTITY = 'myuser, Secret = 'p455w0rd';

CREATE EXTERNAL DATA SOURCE salesforce_data_source
WITH ( 
LOCATION = 'odbc://Salesforce',
CONNECTION_OPTIONS = 'DRIVER={Easysoft Salesforce ODBC Driver};
                      UID=mysalesforceuser@mydomain;
                      PWD=mypassword;TOKEN=1234ABCDEF;',
CREDENTIAL = PolyBaseSalesforce
);

Erstellen Sie eine lokale SQL Server-Tabelle, die die Remote-Salesforce-Daten enthält. Diese lokale Tabelle ist für die Account-Salesforce-Tabelle:

CREATE EXTERNAL TABLE Account([Id] NCHAR(18) COLLATE Latin1_General_CI_AS NOT NULL, [IsDeleted] TINYINT NOT NULL,

Fragen Sie die entfernten Daten ab:

SELECT Id FROM dbo.Account WHERE Id = '001i000000AOq3DXYZ'
