The Snowflake JDBC driver is a vital tool for Java developers who want to connect their applications to Snowflake’s powerful data warehousing platform. In this article, we will walk you through the process of installing and using the Snowflake JDBC driver. Think of it as laying down the groundwork for a successful house (your application) to connect to a real estate giant (Snowflake).

Prerequisites

• Ensure that Java 1.8 or higher is installed on your client machine. The driver requires this version to work effectively.
• You might need either Oracle Java or OpenJDK, depending on your environment.

Installation

There are a couple of ways to install the Snowflake JDBC driver: using Maven or building from the source code.

Maven Installation

Add one of the following dependencies to your Maven project.

For fat-jar:

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

For FIPS compliant fat-jar:

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

For experimental thin-jar:

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

Building from Source Code

To build the driver from source, follow these steps:

1. Clone the repository using:

   git clone https://github.com/snowflakedb/snowflake-jdbc.git

2. Navigate to the directory and build the fat-jar with:

   .mvnw clean verify
   .mvnw org.apache.maven.plugins:maven-install-plugin:3.1.1:install-file -Dfile=target/snowflake-jdbc.jar -DpomFile=.public_pom.xml

3. For FIPS compliant fat-jar, change into the FIPS directory and run:

   cd FIPS
   .mvnw clean verify
   .mvnw org.apache.maven.plugins:maven-install-plugin:3.1.1:install-file -Dfile=target/snowflake-jdbc-fips.jar -DpomFile=.public_pom.xml 
   cd -

4. For the experimental thin-jar:

   .mvnw clean verify -Dnot-self-contained-jar -Dthin-jar
   .mvnw org.apache.maven.plugins:maven-install-plugin:3.1.1:install-file -Dfile=target/snowflake-jdbc-thin.jar -DpomFile=.thin_public_pom.xml -Dnot-self-contained-jar -Dthin-jar

Connecting to Snowflake

Once the driver is installed, you can use it to connect to your Snowflake account. Loading the driver class is essential before you can initiate the connection.

Class.forName("net.snowflake.client.jdbc.SnowflakeDriver");

Next, you will typically use a javax.sql.DataSource interface implemented by the net.snowflake.client.jdbc.SnowflakeBasicDataSource class. Below are examples of connection strings for different regions:

• US (West) Region: jdbc:snowflake:account.snowflakecomputing.com?connection_params
• EU (Frankfurt) Region: jdbc:snowflake:account.eu-central-1.snowflakecomputing.com?connection_params

Troubleshooting

If you face any issues while installing or using the Snowflake JDBC driver, consider the following troubleshooting steps:

• Ensure you have the correct version of Java installed.
• Make sure all Maven dependencies are properly configured.
• Check for network connectivity issues to the Snowflake server.
• If issues persist, refer to the official documentation.

Additional Considerations

Managing your code quality is crucial. To keep your coding style in check, you can run the maven command:

mvn -P check-style validate

To ensure a perfect style format, use:

mvn com.spotify.fmt:fmt-maven-plugin:format
