Release 8.2.2




You can create connections to one or more Microsoft SQL Server databases from Designer Cloud Enterprise Edition


  • If you haven't done so already, you must create and deploy an encryption key file for the Alteryx node to be shared by all relational connections. For more information, see Create Encryption Key File
  • If you plan to create an SSO connection of this type, additional configuration may be required. See Enable SSO for Relational Connections.


To create this connection:

  • In the Import Data page, click the Plus sign. Then, select the Relational tab. Click the SQL Server card. 
  • You can also create connections through the Connections page. See Connections Page.

For additional details on creating a SQL Server connection, see Enable Relational Connections.

This connection can also be created using the API. 

Modify the following properties as needed:

Enter your hostname. Example:
PortSet this value to 1433.
Connect String options

Insert any additional connection parameters, if needed. See below.

User Name(basic credential type only) Username to use to connect to the database.
Password(basic credential type only) Password associated with the above username.
Default Column Data Type Inference

Set to disabled to prevent the platform from applying its own type inference to each column on import. The default value is enabled.

Test ConnectionAfter you have defined the connection credentials type, credentials, and connection string, you can validate those credentials.
Connection NameDisplay name of the connection
Connection DescriptionDescription of the connection, which appears in the application.
