Snowflake provides a JDBC type 4 driver that supports core functionality, allowing Java program to connect to Snowflake.

Prerequisites
=============

The Snowflake JDBC driver requires Java 1.8 or higher. If the minimum required version of Java is not installed on the client machines where the JDBC driver is installed, you must install either Oracle Java or OpenJDK.

Installation
============

Maven
-----
Add following code block as a dependency

.. code-block:: xml

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


Build from Source Code 
----------------------
1. Checkout source code from Github by running:

.. code-block:: bash

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

2. Build the driver by running:

.. code-block:: bash

    mvn install

Usage
=====

Load Driver Class
-----------------

.. code-block:: java

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

Datasource
----------

javax.sql.DataSource interface is implemented by class

.. code-block:: java

    net.snowflake.client.jdbc.SnowflakeBasicDataSource

Connection String
-----------------

US(West) Region:

.. code-block:: bash

    jdbc:snowflake://<account>.snowflakecomputing.com/?<connection_params>


EU(Frankfurt) Region:

.. code-block:: bash

    jdbc:snowflake://<account>.eu-central-1.snowflakecomputing.com/?<connection_params>

Documentation
=============

For detailed documentation, please refer to https://docs.snowflake.net/manuals/user-guide/jdbc.html

Development
=============

Run the maven command to check the coding style.

.. code-block:: bash

    mvn -P check-style verify

Follow the instruction if any error occurs or run this command to fix the formats.

.. code-block:: bash

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

You may import the coding style from IntelliJ so that the coding style can be applied on IDE:

- In the **File** -> **Settings/Plugins**, and install `google-java-format` plugin.
- Enable `google-java-format` for the JDBC project.
- In the source code window, select **Code** -> **Reformat** to apply the coding style.


Tests
=====

Run Tests
---------

Set the environment variables to specify the target database.

.. code-block:: bash

    export SNOWFLAKE_TEST_HOST=<your_host>
    export SNOWFLAKE_TEST_ACCOUNT=<your_account>
    export SNOWFLAKE_TEST_USER=<your_user>
    export SNOWFLAKE_TEST_PASSWORD=<your_password>
    export SNOWFLAKE_TEST_DATABASE=<your_database>
    export SNOWFLAKE_TEST_SCHEMA=<your_schema>
    export SNOWFLAKE_TEST_WAREHOUSE=<your_warehouse>
    export SNOWFLAKE_TEST_ROLE=<your_role>

Run the maven ``verify`` goal.

.. code-block:: bash

    mvn -DjenkinsIT -DtestCategory=net.snowflake.client.category.<category> verify

where ``category`` is the class name under the package ``net.snowflake.client.category``.

Test Class Naming Convention
----------------------------

The test cases are fallen into a couple of criteria:

- The unit test class names end with ``Test``. They run part of the JDBC build jobs.
- The integration test class names end with ``IT``. They run part of the ``verify`` maven goal along with the test category specified by the parameter ``testCategory`` having ``net.snowflake.client.category`` classes.
- The manual test class names end with ``Manual``. They don't run in the CI but you can run them manually.

Aside from the general test criteria, the test case class names ending with ``LatestIT`` run only with the latest JDBC driver.
The main motivation behind is to skip those tests for the old JDBC driver. See ``./TestOnly`` directory for further information.
