Having created external tables for ServiceNow in your SQL Server instance, you are now able to query local and remote data simultaneously. The statement to create an external table based on a ServiceNow incident would look similar to the following: You can refer to the Tables tab of the DSN Configuration Wizard to see the table definition.

The table column definitions must match those exposed by the CData ODBC Driver for ServiceNow.
PUSHDOWN is set to ON by default, meaning the ODBC Driver can leverage server-side processing for complex queries.ĬREATE EXTERNAL DATA SOURCE cdata_servicenow_sourceĬONNECTION_OPTIONS = 'DSN=CData ServiceNow Sys',Īfter creating the external data source, use CREATE EXTERNAL TABLE statements to link to ServiceNow data from your SQL Server instance.

NOTE: IDENTITY and SECRET correspond with the User and Password properties for ServiceNow.ĬREATE DATABASE SCOPED CREDENTIAL servicenow_creds Create an External Data Source for ServiceNow DataĪfter configuring the connection, you need to create a master encryption key and a credential database for the external data source.Įxecute the following SQL command to create a new master key, 'ENCRYPTION,' to encrypt the credentials for the external data source.ĬREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password' Įxecute the following SQL command to create credentials for the external data source connected to ServiceNow data. Navigate to the Tables tab to review the table definitions for ServiceNow. See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.Ĭlick "Test Connection" to ensure that the DSN is connected to ServiceNow properly. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties.
ServiceNow uses the OAuth 2.0 authentication standard. To create an external data source in SQL Server using PolyBase, configure a System DSN (CData ServiceNow Sys is created automatically). You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs. This is the last step of the driver installation. If you have not already, first specify connection properties in an ODBC DSN (data source name). And with PolyBase, you can also join SQL Server data with ServiceNow data, using a single query to pull data from distributed sources. When you issue complex SQL queries from SQL Server to ServiceNow, the driver pushes down supported SQL operations, like filters and aggregations, directly to ServiceNow and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side.

The CData ODBC drivers offer unmatched performance for interacting with live ServiceNow data using PolyBase due to optimized data processing built into the driver. This article walks through creating an external data source and external tables to grant access to live ServiceNow data using T-SQL queries.
When paired with the CData ODBC Driver for ServiceNow, you get access to your ServiceNow data directly alongside your SQL Server data. PolyBase for SQL Server allows you to query external data by using the same Transact-SQL syntax used to query a database table.
