Salesforce DataCloud JDBC Driver

With the Salesforce Data Cloud JDBC driver you can efficiently query millions of rows of data with low latency, and perform bulk data extractions. This driver is read-only and forward-only. It requires Java 8 or greater.

Getting started

To add the driver to your project, add the following Maven dependency:

<dependency>
    <groupId>com.salesforce.datacloud</groupId>
    <artifactId>jdbc</artifactId>
    <version>${jdbc.version}</version>
</dependency>

The class name for this driver is:

com.salesforce.datacloud.jdbc.DataCloudJDBCDriver

Building the driver:

Use the following command to build and test the driver:

mvn clean install

Usage

Connection string

Use jdbc:salesforce-datacloud://login.salesforce.com

JDBC Driver class

Use com.salesforce.datacloud.jdbc.DataCloudJDBCDriver as the driver class name for the JDBC application.

Authentication

We support three of the OAuth authorization flows provided by Salesforce. All of these flows require a connected app be configured for the driver to authenticate as, see the documentation here: connected app overview. Set the following properties appropriately to establish a connection with your chosen OAuth authorization flow:

Parameter	Description
user	The login name of the user.
password	The password of the user.
clientId	The consumer key of the connected app.
clientSecret	The consumer secret of the connected app.
privateKey	The private key of the connected app.
coreToken	OAuth token that a connected app uses to request access to a protected resource on behalf of the client application.
refreshToken	Token obtained from the web server, user-agent, or hybrid app token flow.

username and password authentication:

The documentation for username and password authentication can be found here.

To configure username and password, set properties like so:

Properties properties = new Properties();
properties.put("user", "${userName}");
properties.put("password", "${password}");
properties.put("clientId", "${clientId}");
properties.put("clientSecret", "${clientSecret}");

jwt authentication:

The documentation for jwt authentication can be found here.

Instuctions to generate a private key can be found here

Properties properties = new Properties();
properties.put("privateKey", "${privateKey}");
properties.put("clientId", "${clientId}");
properties.put("clientSecret", "${clientSecret}");

refresh token authentication:

The documentation for refresh token authentication can be found here.

Properties properties = new Properties();
properties.put("coreToken", "${coreToken}");
properties.put("refreshToken", "${refreshToken}");
properties.put("clientId", "${clientId}");
properties.put("clientSecret", "${clientSecret}");

Connection settings

See this page on available connection settings. These settings can be configured in properties by using the prefix serverSetting.

For example, to control locale set the following property:

properties.put("serverSetting.lc_time", "en_US");

---

Generating a private key for jwt authentication

To authenticate using key-pair authentication you'll need to generate a certificate and register it with your connected app.

# create a key pair:
openssl genrsa -out keypair.key 2048
# create a digital certificate, follow the prompts:
openssl req -new -x509 -nodes -sha256 -days 365 -key keypair.key -out certificate.crt
# create a private key from the key pair:
openssl pkcs8 -topk8 -nocrypt -in keypair.key -out private.key

Optional configuration

• dataspace: The data space to query, defaults to "default"
• User-Agent: The User-Agent string identifies the JDBC driver and, optionally, the client application making the database connection.
  By default, the User-Agent string will end with "salesforce-datacloud-jdbc/{version}" and we will prepend any User-Agent provided by the client application.
  For example: "User-Agent: ClientApp/1.2.3 salesforce-datacloud-jdbc/1.0"

Usage sample code

public static void executeQuery() throws ClassNotFoundException, SQLException {
    Class.forName("com.salesforce.datacloud.jdbc.DataCloudJDBCDriver");

    Properties properties = new Properties();
    properties.put("user", "${userName}");
    properties.put("password", "${password}");
    properties.put("clientId", "${clientId}");
    properties.put("clientSecret", "${clientSecret}");

    try (var connection = DriverManager.getConnection("jdbc:salesforce-datacloud://login.salesforce.com", properties);
         var statement = connection.createStatement()) {
        var resultSet = statement.executeQuery("${query}");

        while (resultSet.next()) {
            // Iterate over the result set
        }
    }
}

Generated assertions

Some of our classes are tested using assertions generated with the assertj assertions generator. Due to some transient test-compile issues we experienced, we checked in generated assertions for some of our classes. If you make changes to any of these classes, you will need to re-run the assertion generator to have the appropriate assertions available for that class.

To find examples of these generated assertions, look for files with the path **/test/**/*Assert.java.

To re-generate these assertions execute the following command:

mvn assertj:generate-assertions
