Connect to Nuclia Data in RazorSQL

The CData JDBC Driver for Nuclia enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to Nuclia using wizards in RazorSQL.

Create a JDBC Data Source for Nuclia Data

1. Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
2. In the Connection Wizard that appears, set the following properties:
   • Driver Location: Set this property to the path to the lib subfolder in the installation directory.
   • Driver Class: Set the driver class to cdata.jdbc.api.APIDriver.
   • Username: Enter the username. (This property can also be set in the JDBC URL.)
   • Password: Enter the password. (This property can also be set in the JDBC URL.)

   • JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:api: and is followed by a semicolon-separated list of connection properties.

     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.

     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.

     

     A typical JDBC URL is the following:

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

Query Nuclia Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
