Microsoft SQL credentials#

You can use these credentials to authenticate the following nodes:

Prerequisites#

Create a user account on a Microsoft SQL server database.

Supported authentication methods#

  • SQL database connection

Refer to Microsoft's Connect to SQL Server documentation for more information about connecting to the service.

Using SQL database connection#

To configure this credential, you'll need:

  • The Server name
  • The Database name
  • Your User account/ID
  • Your Password
  • The Port to use for the connection
  • The Domain name
  • Whether to use TLS
  • Whether to Ignore SSL Issues
  • The Connect Timeout
  • The Request Timeout
  • The TDS Version the connection should use

To set up the database connection:

  1. Enter the SQL Server Host Name as the Server. In an existing SQL Server connection, the host name comes before the instance name in the format HOSTNAME\INSTANCENAME. Find the host name:
  2. Enter the SQL Server Instance Name as the Database name. Find this name using the same steps listed above for finding the host name.
    • If you don't see an instance name in any of these places, then your database uses the default MSSQLSERVER instance name.
  3. Enter your User account name or ID.
  4. Enter your Password.
  5. For the Port:
    • SQL Server defaults to 1433.
    • If you can't connect over port 1433, check the Error logs for the phrase Server is listening on to identify the port number you should enter.

  6. You only need to enter the Domain name if users in multiple domains access your database. Run this SQL query to get the domain name:

    1
    SELECT DEFAULT_DOMAIN()[DomainName];

  7. Select whether to use TLS.

  8. Select whether to Ignore SSL Issues: If turned on, the credential will connect even if SSL certificate validation fails.
  9. Enter the number of milliseconds n8n should attempt the initial connection to complete before disconnecting as the Connect Timeout. Refer to the SqlConnection.ConnectionTimeout property documentation for more information.
    • SQL Server stores this timeout as seconds, while n8n stores it as milliseconds. If you're copying your SQL Server defaults, multiple by 100 before entering the number here.
  10. Enter the number of milliseconds n8n should wait on a given request before timing out as the Request Timeout. This is basically a query timeout parameter. Refer to Troubleshoot query time-out errors for more information.
  11. Select the Tabular Data Stream (TDS) protocol to use from the TDS Version dropdown. If the server doesn't support the version you select here, the connection uses a negotiated alternate version. Refer to Appendix A: Product Behavior for a more detailed breakdown of the TDS versions' compatibility with different SQL Server versions and .NET frameworks. Options include:
    • 7_4 (SQL Server 2012 ~ 2019): TDS version 7.4.
    • 7_3_B (SQL Server 2008R2): TDS version 7.3.B.
    • 7_3_A (SQL Server 2008): TDS version 7.3.A.
    • 7_2 (SQL Server 2005): TDS version 7.2.
    • 7_1 (SQL Server 2000): TDS version 7.1.
