Load data from Snowflake

This article describes how to connect to Snowflake with Exasol and then load data.

Prerequisites

  • Snowflake must be reachable from the Exasol system.

  • The user credentials in the connection must be valid.

Download driver

Download the latest JDBC driver from the Snowflake website: Downloading / integrating the JDBC Driver.

Add JDBC driver

To add the JDBC driver in Exasol, create a configuration file called settings.cfg with the following settings:

DRIVERNAME=Snowflake
PREFIX=jdbc:snowflake:
FETCHSIZE=100000
INSERTSIZE=-1
NOSECURITY=YES

Follow the procedure described in Add JDBC Driver to upload the settings.cfg configuration and JDBC driver files to Exasol.

Create connection

To create a connection, run the following statement. Replace the placeholders in the connection string and credentials with the corresponding values for your Snowflake account. 

-- Create a connection to Snowflake
CREATE OR REPLACE CONNECTION SNOWFLAKE_CONNECTION TO
  'jdbc:snowflake://<myorganization>-<myaccount>.snowflakecomputing.com/?warehouse=<my_compute_wh>&role=<my_role>&CLIENT_SESSION_KEEP_ALIVE=true'
  USER '<sfuser>' IDENTIFIED BY '<sfpwd>';

To test the connection, run the following statement.

SELECT * FROM 
(
IMPORT FROM jdbc AT SNOWFLAKE_CONNECTION
STATEMENT 'select ''Connection works!'' as connection_status'
);

Load data

Use IMPORT to load data from a table or SQL statement using the connection that you created.
