Query Nuclia Data in DataGrip

DataGrip is a database IDE that allows SQL developers to query, create, and manage databases. When paired with the CData API Driver for JDBC, DataGrip can work with live Nuclia data. This article shows how to establish a connection to Nuclia data in DataGrip.

Create a New Driver Definition for Nuclia

The steps below describe how to create a new Data Source in DataGrip for Nuclia.

1. In DataGrip, click File -> New > Project and name the project
2. In the Database Explorer, click the plus icon () and select Driver.
3. In the Driver tab:
   • Set Name to a user-friendly name (e.g. "CData Nuclia Driver")
   • Set Driver Files to the appropriate JAR file. To add the file, click the plus (), select "Add Files," navigate to the "lib" folder in the driver's installation directory and select the JAR file (e.g. cdata.jdbc.api.jar).
   • Set Class to cdata.jdbc.api.API.jar
   Additionally, in the advanced tab you can change driver properties and some other settings like VM Options, VM environment, VM home path, DBMS, etc
   • For most cases, change the DBMS type to "Unknown" in Expert options to avoid native SQL Server queries (Transact-SQL), which might result in an invalid function error
4. Click "Apply" then "OK" to save the Connection

Configure a Connection to Nuclia

1. Once the connection is saved, click the plus (), then "Data Source" then "CData Nuclia Driver" to create a new Nuclia Data Source.
2. In the new window, configure the connection to Nuclia with a JDBC URL.

   Built-in Connection String Designer

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

         java -jar cdata.jdbc.api.jar
       

   Fill in the connection properties and copy the connection string to the clipboard.

   Using API Key Authentication

   Nuclia uses API key authentication for accessing Knowledge Box data. To obtain an API key:

   1. Log in to the Nuclia Cloud Dashboard at https://nuclia.cloud
   2. Navigate to your Knowledge Box settings
   3. Go to the Service Accounts section
   4. Create a new service account or copy an existing API key

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Nuclia service account API key.
   • KbId: Set this to your Knowledge Box UUID.
   • Zone: Set this to your Nuclia deployment zone (e.g., aws-us-east-2-1).

   Example Connection String

   Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;
   

   Connecting to Nuclia

   Once the authentication is configured, you can connect to Nuclia and query data from any of the available tables such as Resources, KnowledgeBox, LabelSets, and ProcessingStatus.

   
3. Set URL to the connection string, e.g.,

   jdbc:api:Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;

4. Click "Apply" and "OK" to save the connection string

At this point, you will see the data source in the Data Explorer.

Execute SQL Queries Against Nuclia

To browse through the Nuclia entities (available as tables) accessible through the JDBC Driver, expand the Data Source.

To execute queries, right click on any table and select "New" -> "Query Console."

In the Console, write the SQL query you wish to execute. For example:

SELECT ,  FROM KnowledgeBox WHERE  = ''
