Salesforce Icon Salesforce ODBC Driver

The Salesforce ODBC Driver is a powerful tool that allows you to connect with live Salesforce account data, directly from any applications that support ODBC connectivity.

Access Salesforce data like you would a database - read, write, and update Leads, Contacts, Opportunities, Accounts, etc. through a standard ODBC Driver interface.

Analyze Salesforce Data in R


Create data visualizations and use high-performance statistical functions to analyze Salesforce data in Microsoft R Open.

Access Salesforce data with pure R script and standard SQL. You can use the CData ODBC Driver for Salesforce and the RODBC package to work with remote Salesforce data in R. By using the CData Driver, you are leveraging a driver written for industry-proven standards to access your data in the popular, open-source R language. This article shows how to use the driver to execute SQL queries to Salesforce data and visualize Salesforce data in R.

Install R

You can complement the driver's performance gains from multi-threading and managed code by running the multithreaded Microsoft R Open or by running R linked with the BLAS/LAPACK libraries. This article uses Microsoft R Open (MRO).

Connect to Salesforce as an ODBC Data Source

Information for connecting to Salesforce follows, along with different instructions for configuring a DSN in Windows and Linux environments.

There are several authentication methods available for connecting to Salesforce: Login, OAuth, and SSO. The Login method requires you to have the username, password, and security token of the user.

If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication.

SSO (single sign-on) can be used by setting the SSOProperties, SSOLoginUrl, and TokenUrl connection properties, which allow you to authenticate to an identity provider. See the "Getting Started" chapter in the help documentation for more information.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for Salesforce in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData Salesforce Source] Driver = CData ODBC Driver for Salesforce Description = My Description User = username Password = password SecurityToken = Your_Security_Token

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Load the RODBC Package

To use the driver, download the RODBC package. In RStudio, click Tools -> Install Packages and enter RODBC in the Packages box.

After installing the RODBC package, the following line loads the package:

library(RODBC)

Note: This article uses RODBC version 1.3-12. Using Microsoft R Open, you can test with the same version, using the checkpoint capabilities of Microsoft's MRAN repository. The checkpoint command enables you to install packages from a snapshot of the CRAN repository, hosted on the MRAN repository. The snapshot taken Jan. 1, 2016 contains version 1.3-12.

library(checkpoint) checkpoint("2016-01-01")

Connect to Salesforce Data as an ODBC Data Source

You can connect to a DSN in R with the following line:

conn <- odbcConnect("CData Salesforce Source")

Schema Discovery

The driver models Salesforce APIs as relational tables, views, and stored procedures. Use the following line to retrieve the list of tables:

sqlTables(conn)

Execute SQL Queries

Use the sqlQuery function to execute any SQL query supported by the Salesforce API.

account <- sqlQuery(conn, "SELECT Contact.Name, SUM(Account.AnnualRevenue) FROM Contact, Account GROUP BY Contact.Name", believeNRows=FALSE, rows_at_time=1)

You can view the results in a data viewer window with the following command:

View(account)

Plot Salesforce Data

You can now analyze Salesforce data with any of the data visualization packages available in the CRAN repository. You can create simple bar plots with the built-in bar plot function:

par(las=2,ps=10,mar=c(5,15,4,2)) barplot(account$AnnualRevenue, main="Salesforce Account", names.arg = account$Industry, horiz=TRUE)
