Access Live Harvest Data in Coginiti Pro

Coginiti Pro is a single tool for all your SQL data and analytics needs, designed specifically for data engineers, analysts, and data scientists. When paired with the CData API Driver for JDBC, Coginiti Pro can access and query live Harvest data. This article describes how to connect to and query Harvest data from Coginiti Pro.

With built-in optimized data processing, the CData API Driver for JDBC offers unmatched performance for interacting with live Harvest data. When you issue complex SQL queries to Harvest, the driver pushes supported SQL operations, like filters and aggregations, directly to Harvest and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). In addition, its built-in dynamic metadata querying allows you to work with and analyze Harvest data using native data types.

Gather Connection Properties and Build a Connection String

Download the CData API Driver for JDBC installer, unzip the package, and run the JAR file to install the driver. Then gather the required connection properties.

Start by setting the Profile connection property to the location of the Harvest Profile on disk (e.g. C:\profiles\Harvest.apip). Next, set the ProfileSettings connection property to the connection string for Harvest (see below).

Harvest API Profile Settings

To authenticate to Harvest, you can use either Token authentication or the OAuth standard. Use Basic authentication to connect to your own data. Use OAuth to allow other users to connect to their data.

Using Token Authentication

To use Token Authentication, set the APIKey to your Harvest Personal Access Token in the ProfileSettings connection property. In addition to APIKey, set your AccountId in ProfileSettings to connect.

Using OAuth Authentication

First, register an OAuth2 application with Harvest. The application can be created from the "Developers" section of Harvest ID.

After setting the following connection properties, you are ready to connect:

• ProfileSettings: Set your AccountId in ProfileSettings.
• AuthScheme: Set this to OAuth.
• OAuthClientId: Set this to the client ID that you specified in your app settings.
• OAuthClientSecret: Set this to the client secret that you specified in your app settings.
• CallbackURL: Set this to the Redirect URI that you specified in your app settings.
• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage how the driver obtains and refreshes the OAuthAccessToken.

NOTE: To use the JDBC driver in Coginiti Pro, you may need a license (full or trial) and a Runtime Key (RTK). For more information on obtaining this license (or a trial), contact our sales team.

Built-in Connection String Designer

For assistance constructing the JDBC URL, use the connection string designer built into the Harvest JDBC Driver. Double-click the JAR file or execute the jar file from the command line.

Fill in the connection properties (including the RTK) and copy the connection string to the clipboard.

Create a JDBC Data Source for Harvest Data

1. Open Coginiti Pro and in the File menu, select "Edit Drivers."
2. In the newly opened wizard, click "Add" and select "Generic."

3. In the "JDBC Drivers" wizard, set the driver properties (below) and click "Create Driver."

   • Set JDBC Driver Name to a useful name, like CData JDBC Driver for Harvest.
   • Click "Add Files" to add the JAR file from the "lib" folder in the installation directory (e.g. cdata.jdbc.api.jar)
   • Select the Class Name: cdata.jdbc.api.APIDriver.

Create a Connection using the CData API Driver for JDBC

1. In the File menu, click "Edit Connections."
2. In the newly opened wizard, click "Add" and select "Generic."
3. In the "Connections" wizard, set the connection properties.
   • Set Connection name to an identifying name.
   • Set Database JDBC driver to the Driver you configured earlier.
   • Set JDBC URL to the JDBC URL configured using the built-in connection string designer (e.g. jdbc:api:Profile=C:\profiles\Harvest.apip;ProfileSettings='APIKey=my_personal_key;AccountId=_your_account_id';
4. Click "Test" to ensure the connection is configured properly. Click "Save."

Query Harvest Using SQL

1. Open the Connections tab by clicking on database icon: .
2. Click the plus sign () to add a new query tab.

3. Once the query console is open, write the SQL script you wish to execute and click "Run at Cursor".

   NOTE: You can use the explorer on the left to determine table/view names and column names.

   Using the explorer

   1. In the "Select connection" field, select the connection you wish to query.
   2. Expand your newly created connection, expand the "CData" catalog, and expand the Harvest catalog.
   3. Expand "Tables" or "Views" to find the entity you wish to query.
   4. Expand your selected entity to explore the fields (columns).
