4. Give the desired connection name.

5. Enter the DSN or DSN-less connection string for the database platform in question as follows:


SQL Server (DSN-less)

ssvb:DRIVER={SQL Server XX Driver};Database=XXXX;Server=hostname\InstanceName;UID=XXXX;pwd=XXXX

Example for SQL Server Authentication/ODBC/Bulk Loader:

Example for Windows Authentication/ODBC/Bulk Loader:
ssvb:DRIVER={ODBC Driver 17 for SQL Server};DATABASE=MYDB;SERVER=MYLOCALHOST\INSTANCE;Trusted_Connection=yes

Note 1

Once the connection is saved, the password will be encrypted with the value __EncPwd1__ in the connection string.

Note 2

For more information on different attributes to include in the connection string, see the Microsoft connection string documentation for SQL Server.


Snowflake (DSN)


Example for Snowflake Authentication/ODBC/Bulk Loader/Local Staging Option:

Example for Snowflake Authentication/ODBC/Bulk Loader/Amazon S3 Staging Option:

Note 1

The Amazon S3 URL and Region may be different based on your organization's configuration.

Note 2

From Alteryx Designer version 2021.4+ onwards we support Snowflake DSN-less for Bulk connections using Data Connection Manager (DCM). 


Prior to Alteryx Designer version 2021.4 Snowflake DSN-less was not supported for Bulk connections. A DSN must be used to avoid errors.

6. Don't forget to grant the appropriate user(s)/Studio(s) to the new Data Connection.

7. The data connection is ready to be used in future workflows to users that have been granted for it.

@GT ,


Is it possible to set up a "DSN-less" Bulk Loader for Snowflake? I've tried different strings without luck, for example:




I've noticed that you've only shown an example where a DSN must be provided to set up the connection. But having a lot of users and diferent business domains to proxy our connections, creating endless DSNs does will not scale.
