Conectando o PolyBase ao Salesforce.com

O PolyBase acessa e combina dados não relacionais e relacionais, tudo de dentro do SQL Server. A partir do SQL Server 2019, o PolyBase oferece suporte a dados de back-ends para os quais um driver ODBC está disponível.

Tentamos o PolyBase com nosso driver ODBC do Salesforce para consultar dados do Salesforce do SQL Server 2019.
Para começar:

Instale e licencie o driver ODBC do Salesforce.com na máquina em que o SQL Server está instalado.
Você precisa da versão 2.0.3 do driver ODBC do Salesforce.com, que está disponível no momento entrando em contato com a equipe de suporte da Easysoft ().
No Microsoft SQL Server Management Studio, conecte-se à sua instância do SQL Server habilitada para PolyBase. Para verificar se o PolyBase está instalado, execute esta consulta:
```
SELECT SERVERPROPERTY ('IsPolyBaseInstalled') AS IsPolyBaseInstalled;
```
Se o PolyBase estiver instalado, esta consulta retornará:
```
1
```

Você também precisa garantir que o PolyBase esteja ativado:

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

Se ainda não tiver feito isso, inicie os serviços PolyBase (SQL Server PolyBase Engine, SQL Server PolyBase Data Movement) no aplicativo Windows Services.

Crie uma fonte de dados externa PolyBase:

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
);

Crie uma tabela local do SQL Server que conterá os dados remotos do Salesforce. Esta tabela local é para a tabela Account Salesforce:

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