Downloading / Integrating the JDBC Driver

The JDBC driver (snowflake-jdbc) is provided as a JAR file, available as an artifact in Maven for download or integrating directly into your Java-based projects.

Before downloading or integrating the driver, you may want to first verify the version of the driver you are currently using. To verify your driver version, connect to Snowflake through a client application that uses the driver and check the driver version. If the application supports executing SQL queries, you can do this by calling the CURRENT_CLIENT function.

Requirements

For a list of the operating systems supported by Snowflake clients, see Operating System Support.

Downloading the Driver

To download the driver:

  1. Go to the Maven Central Repository:

    https://repo1.maven.org/maven2/net/snowflake/snowflake-jdbc

  2. Click on the directory for the version that you need.

    The most recent version (3.13.8) is not always at the end of the list. Versions are listed alphabetically, not numerically. For example, 3.10.x comes after 3.1.x, not after 3.9.x.

  3. Download the snowflake-jdbc-#.#.#.jar file.

  4. If you plan to verify the driver package signature, download the snowflake-jdbc-#.#.#.jar.asc file.

Verifying the Driver Package Signature — Optional

To optionally verify the JDBC driver package signature:

  1. Download and import the latest Snowflake GPG public key from the public keyserver:

    $ gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys <GPG_KEY_ID>
    

    For <GPG_KEY_ID>, specify one of the following key IDs:

    JDBC Driver Version

    GPG Key ID

    3.12.13 and higher

    37C7086698CB005C

    3.6.26 through 3.12.12

    EC218558EABB25A1

    Up to 3.6.25

    93DB296A69BE019A

    Note

    If this command fails with the following error:

    gpg: keyserver receive failed: Server indicated a failure
    

    then specify that you want to use port 80 for the keyserver:

    gpg --keyserver hkp://keyserver.ubuntu.com:80  ...
    
  2. Run the gpg --verify command to verify the signature of the package.

    For the --verify command-line flag, specify the .asc file that you downloaded earlier as the signature file and the JAR file as the file containing the signed data.

    For example:

    $ gpg --verify snowflake-jdbc-3.13.8.jar.asc snowflake-jdbc-3.13.8.jar
    gpg: Signature made Wed 22 Feb 2017 04:31:58 PM UTC using RSA key ID <gpg_key_id>
    gpg: Good signature from "Snowflake Computing <snowflake_gpg@snowflake.net>"

    Specify the correct version numbers for the JDBC driver package you are verifying. Version 3.13.8 is used in this example for illustration purposes only. The latest available version of the driver may be higher.

    Note

    Verifying the signature produces a warning similar to the following:

    gpg: Signature made Mon 24 Sep 2018 03:03:45 AM UTC using RSA key ID <gpg_key_id>
    gpg: Good signature from "Snowflake Computing <snowflake_gpg@snowflake.net>" unknown
    gpg: WARNING: This key is not certified with a trusted signature!
    gpg: There is no indication that the signature belongs to the owner.
    

    To avoid the warning, you can grant the Snowflake GPG public key implicit trust.

  3. Your local environment can contain multiple GPG keys; however, for security reasons, Snowflake periodically rotates the public GPG key. As a best practice, we recommend deleting the existing public key after confirming that the latest key works with the latest signed package:

    $ gpg --delete-key "Snowflake Computing"
    

Integrating the Driver into a Maven Project

To integrate the driver into a Maven project, add the driver as a dependency to your pom.xml file. For example:

<dependencies>
  ...
  <dependency>
    <groupId>net.snowflake</groupId>
    <artifactId>snowflake-jdbc</artifactId>
    <version>3.13.8</version>
  </dependency>
  ...
</dependencies>

Where the <version> tag specifies the version of the driver you wish to integrate. Note that version 3.13.8 is used in this example for illustration purposes only. The latest available version of the driver may be higher.

The developer notes are hosted along with the source code on GitHub.

Adding the JNA Classes to Your Classpath

Connection caching for browser-based SSO and token caching for multi-factor authentication (MFA) require the use of the Java Native Access (JNA) classes to save data securely to the filesystem.

As of version 3.12.18 of the JDBC Driver, the JNA classes are no longer packaged in the JDBC Driver JAR file. In the JDBC Driver pom.xml file, the dependencies on these classes are marked as optional.

If you need to use connection caching or token caching, you must add the following libraries to your classpath:

The pom.xml file for the JDBC Driver specifies the version of the JNA classes that have been tested with the JDBC Driver. We recommend using this version (or the same major version) of the JNA classes.

Note

For systems that use the aarch64 architecture (e.g. the Apple M1 chip), use version 5.7.0 or later of the JNA libraries. (JNA versions prior to v5.7.0 are not compatible with Windows and macOS systems that run on aarch64.)
