Hi all,
At present, Alteryx does not support DSN-free connections to Snowflake using the Bulk Connector. This is a critical functionality for any large company that uses Alteryx - and so I'm hoping that this can be changed in the product in an upcoming release. As a corollary - every DB connection type has to be able to work without DSNs for any medium or large size server instance - so it's worth extending this to check every DB connection type available in Alteryx.
Here are the details:
What is DSN-Free?
In order to be able to run our Alteryx canvasses on a multi-node server - we have to avoid using DSNs - so we generally expand connection strings that look like this:
odbc:DSN=DSNSnowFlakeTest;UID=Username;PWD=__EncPwd1__|||NEWTESTDB.PUBLIC.MYTESTTABLE
to instead have the fully described connection string like this:
odbc:DRIVER={SnowflakeDSIIDriver};UID=Username;pwd=__EncPwd1__;authenticator=Snowflake;WAREHOUSE=compute_wh;SERVER=xnb27844.us-east-1.snowflakecomputing.com;SCHEMA=PUBLIC;DATABASE=NewTestDB;Staging=local;Method=user
For Snowflake BL:
Now - for the Snowflake Bulk Loader the same process does not work and Alteryx gives the classic error below
With DSN:
snowbl:DSN=DSNSnowFlakeTest;UID=Username;pwd=__EncPwd1__;Staging=local;Method=user|||NEWTESTDB.PUBLIC.MYTESTTABLE
Without DSN:
snowbl:driver=SnowflakeDSIIDriver;UID=SeanBAdamsJPMC;pwd=__EncPwd1__;SERVER=xnb27844.us-east-1.snowflakecomputing.com;WAREHOUSE=compute_wh;SCHEMA=PUBLIC;DATABASE=NewTestDB;Staging=local;Method=user|||NEWTESTDB.PUBLIC.MYTESTTABLE
Output Data (6) Error SQLDriverConnect: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified" which indicates that the driver details may be wrong
Many thanks
Sean
