Ansluter PolyBase till Salesforce.com

PolyBase får åtkomst till och kombinerar både icke-relationell och relationsdata, allt från SQL Server. Från och med SQL Server 2019 stöder PolyBase data från backends för vilka en ODBC-drivrutin är tillgänglig.

Vi försökte PolyBase med vår Salesforce ODBC-drivrutin för att fråga Salesforce-data från SQL Server 2019.

För att komma igång:

1. Installera och licensiera Salesforce.com ODBC-drivrutinen på maskinen där SQL Server är installerad.

   Du behöver build 2.0.3 av Salesforce.com ODBC-drivrutinen, som för närvarande är tillgänglig genom att kontakta Easysofts supportteam ().

2. I Microsoft SQL Server Management Studio, anslut till din PolyBase-aktiverade SQL Server-instans. För att kontrollera om PolyBase är installerat, kör den här frågan:

   SELECT SERVERPROPERTY ('IsPolyBaseInstalled') AS IsPolyBaseInstalled;

   Om PolyBase är installerat kommer denna fråga att returnera:

   1

3. Du måste också se till att PolyBase är aktiverat:

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

4. Om du inte redan har gjort det, starta PolyBase-tjänsterna (SQL Server PolyBase Engine, SQL Server PolyBase Data Movement) i Windows Services-applikationen.
5. Skapa en extern PolyBase-datakälla:

   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
   );
   

6. Skapa en lokal SQL Server-tabell som innehåller Salesforce-fjärrdata. Den här lokala tabellen är för konto Salesforce-tabellen:

   CREATE EXTERNAL TABLE Account([Id] NCHAR(18) COLLATE Latin1_General_CI_AS NOT NULL, [IsDeleted] TINYINT NOT NULL,
   	                      [MasterRecordId] NCHAR(18) COLLATE Latin1_General_CI_AS,
   			      [Name] NVARCHAR(255) COLLATE Latin1_General_CI_AS NOT NULL, [Type] NVARCHAR(255) COLLATE Latin1_General_CI_AS,

   			      [ShippingCountryCode] NVARCHAR(255) COLLATE Latin1_General_CI_AS, [ShippingLatitude] FLOAT(53), [ShippingLongitude] FLOAT(53),
   			      [ShippingAddress] NVARCHAR(4000) COLLATE Latin1_General_CI_AS, [Phone] NVARCHAR(40) COLLATE Latin1_General_CI_AS,

   			      [Sic] NVARCHAR(20) COLLATE Latin1_General_CI_AS, [Industry] NVARCHAR(255) COLLATE Latin1_General_CI_AS, [AnnualRevenue] FLOAT(53),
   			      [NumberOfEmployees] INT, [Ownership] NVARCHAR(255) COLLATE Latin1_General_CI_AS, [TickerSymbol] NVARCHAR(20) COLLATE Latin1_General_CI_AS,
   			      [Description] NVARCHAR(4000) COLLATE Latin1_General_CI_AS, [Rating] NVARCHAR(255) COLLATE Latin1_General_CI_AS,
   			      [Site] NVARCHAR(80) COLLATE Latin1_General_CI_AS, [OwnerId] NCHAR(18) COLLATE Latin1_General_CI_AS NOT NULL,
   			      [CreatedDate] DATETIME2(0) NOT NULL, [CreatedById] NCHAR(18) COLLATE Latin1_General_CI_AS NOT NULL,
   			      [LastModifiedDate] DATETIME2(0) NOT NULL, [LastModifiedById] NCHAR(18) COLLATE Latin1_General_CI_AS NOT NULL,
   			      [SystemModstamp] DATETIME2(0) NOT NULL, [LastActivityDate] DATE, [LastViewedDate] DATETIME2(0), [LastReferencedDate] DATETIME2(0),
   			      [Jigsaw] NVARCHAR(20) COLLATE Latin1_General_CI_AS, [JigsawCompanyId] NVARCHAR(20) COLLATE Latin1_General_CI_AS,
   			      [AccountSource] NVARCHAR(255) COLLATE Latin1_General_CI_AS, [SicDesc] NVARCHAR(80) COLLATE Latin1_General_CI_AS,
   			      [CustomerPriority__c] NVARCHAR(255) COLLATE Latin1_General_CI_AS, [SLA__c] NVARCHAR(255) COLLATE Latin1_General_CI_AS,
   			      [Active__c] NVARCHAR(255) COLLATE Latin1_General_CI_AS, [NumberofLocations__c] FLOAT(53),
   			      [UpsellOpportunity__c] NVARCHAR(255) COLLATE Latin1_General_CI_AS, [SLASerialNumber__c] NVARCHAR(10) COLLATE Latin1_General_CI_AS,
   			      [SLAExpirationDate__c] DATE)
   	WITH (LOCATION='Account', DATA_SOURCE= salesforce_data_source)

7. Fråga fjärrdata:

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