Connect to Raisers Edge NXT Data as an External Data Source using PolyBase

PolyBase for SQL Server allows you to query external data by using the same Transact-SQL syntax used to query a database table. When paired with the CData ODBC Driver for Raisers Edge NXT, you get access to your Raisers Edge NXT data directly alongside your SQL Server data. This article describes creating an external data source and external tables to grant access to live Raisers Edge NXT data using T-SQL queries.

NOTE: PolyBase is only available on SQL Server 19 and above.

CData Connect AI provides a pure SQL Server interface for Raisers Edge NXT, allowing you to query data from Raisers Edge NXT without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc.) directly to Raisers Edge NXT, leveraging server-side processing to return the requested Raisers Edge NXT data quickly.

Configure Raisers Edge NXT Connectivity for PolyBase

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create. 👁 Creating a new PAT
   
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Raisers Edge NXT data from Polybase.

Create an External Data Source for Raisers Edge NXT Data

After configuring the connection, you need to create a credential database for the external data source.

Creating a Credential Database

Execute the following SQL command to create credentials for the external data source connected to Raisers Edge NXT data.

NOTE: Set IDENTITY to your Connect AI username and set SECRET to your Personal Access Token.

CREATE DATABASE SCOPED CREDENTIAL ConnectCloudCredentials
WITH IDENTITY = 'yourusername', SECRET = 'yourPAT';

Create an External Data Source for Raisers Edge NXT

Execute a CREATE EXTERNAL DATA SOURCE SQL command to create an external data source for Raisers Edge NXT with PolyBase:

CREATE EXTERNAL DATA SOURCE ConnectCloudInstance
WITH ( 
 LOCATION = 'sqlserver://tds.cdata.com:14333',
 PUSHDOWN = ON,
 CREDENTIAL = ConnectCloudCredentials
);

Create External Tables for Raisers Edge NXT

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to Raisers Edge NXT data from your SQL Server instance. The table column definitions must match those exposed by CData Connect AI. You can use the Data Explorer in Connect AI to see the table definition.

Sample CREATE TABLE Statement

Execute a CREATE EXTERNAL TABLE SQL command to create the external table(s), using the collation and setting the LOCATION to three-part notation for the connection, catalog, and table. The statement to create an external table based on a Raisers Edge NXT Constituents would look similar to the following.

CREATE EXTERNAL TABLE Constituents(
 Id COLLATE [nvarchar](255) NULL,
 AddressLines COLLATE [nvarchar](255) NULL,
 ...
) WITH ( 
 LOCATION='RaiserEdgeNXT1.RaiserEdgeNXT.Constituents',
 DATA_SOURCE=ConnectCloudInstance
);
