Use the ServiceNow ODBC driver in SQL Server as a Linked Server.

Using the ODBC driver in SQL Server as a Linked Server allows SQL Server to query tables from a ServiceNow instance directly via the ODBC driver. Only use the procedures described with SQL Server 2008 and 2012. Other versions of SQL Server may cause unexpected behavior. If you encounter unexpected behavior, refer to the troubleshooting linked server Knowledge Base article.

Required Permissions

Additional information on the required permissions for SQL Server Linked Servers can be found on the MSDN blog.
Note: Review this information if you encounter permission errors with SQL Server.
