Snowflake JDBC Connections

Note

This connection type is disabled by default. For more information on enabling this connection type, please contact, Alteryx Support.

You can create connections through the Trifacta Application to a Snowflake JDBC (Private Preview) database, which provides column-oriented in-memory data storage, processing, analytic solutions.

  • Supports Basic credentials type.

  • Supports custom queries.

  • Uses native JDBC driver.

Tip

This connection type can be used to connect to Snowflake JDBC (Private Preview) instances hosted in Azure.

Limitations

Note

This connection type provides direct JDBC connections to specific snowflake databases. It does not enable staging of data for storage in a Snowflake data warehouse. For more information, see Snowflake Connections.

Note

During normal selection or import of an entire table, you may encounter an error indicating a problem with a specific column. Since some tables require filtering based on a particular column, data from them can only be ingested using custom SQL statements. In this case, the problematic column can be used as a filter in the WHERE clause of a custom SQL statement to ingest the table.

  • For more information, please consult the CData driver documentation for the specific table.

  • For more information on using custom SQL, see Create Dataset with SQL.

Note

For filtering date columns, this connection type supports a set of literal functions on dates. You can use these to reduce the volume of data extracted from the database using a custom SQL query. For more information, see the pg_dateliteralfunctions.htm page in the driver documentation for this connection type.
