How to connect to Discourse Data in DBVisualizer

The CData API Driver for JDBC implements JDBC standards to provide connectivity to Discourse data in applications ranging from business intelligence tools to IDEs. This article shows how to establish a connection to Discourse data in DBVisualizer and use the table editor to load Discourse data.

Create a New Driver Definition for Discourse Data

Follow the steps below to use the Driver Manager to provide connectivity to Discourse data from DBVisualizer tools.

1. In DBVisualizer, click Tools -> Driver Manager.
2. Click the plus sign "" to create a new driver.
3. Select "Custom" as the template.
4. On the Driver Settings tab:
   • Set Name to a user-friendly name (e.g. "CData Discourse Driver")
   • Set URL Format to jdbc:api: 👁 Setting the Driver Settings (Salesforce is shown).
     
   • In Driver artifacts and jar files (jars are loaded in order from top):
     1. Click the plus sign "" -> "Add Files"
     2. Navigate to the "lib" folder in the installation directory (C:\Program Files\CData API Driver for JDBC XXXX\)
     3. Select the JAR file (cdata.jdbc.API.jar) and click "Open"
     👁 Loading the driver JAR file.
     
5. The Driver Class should populate automatically. If not, select class (cdata.jdbc.api.APIDriver).

👁 The configured JDBC driver. (Salesforce is shown.)

Define the Connection to the JDBC Data Source

Close the "Driver Manager" and follow the steps below to save connection properties in the JDBC URL.

1. In the "Databases" tab, click the plus sign "" and select the driver you just created.

2. In the "Connection" section, set the following options:

   • Database Type: If you selected the wizard option, the database type is automatically detected. If you selected the "No Wizard" option, select the Generic or Auto Detect option in the Database Type menu.
   • Driver Type: Select the driver you just created.

   • Database URL: Enter the full JDBC URL. The syntax of the JDBC URL is jdbc:api: followed by the connection properties in a semicolon-separated list of name-value pairs.

     The Discourse API uses API Key authentication.

     Using API Key Authentication

     Discourse requires API Key and Username for authentication. API Keys are generated in the Discourse Admin panel under the API section. You can create user-specific API keys or all-users API keys. Once you have obtained the API Key, set it along with the Domain and Username in the ProfileSettings connection property.

     Example Connection string

     Profile=C:\profiles\Discourse.apip;ProfileSettings='Domain=forum.example.com;APIKey=your_api_key;Username=your_username;'AuthScheme=APIKey;
     

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Discourse 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.

     When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

     A typical connection string is below:

     jdbc:api:Profile=C:\profiles\Discourse.apip;ProfileSettings='Domain=forum.example.com;APIKey=your_api_key;Username=your_username;'AuthScheme=APIKey;
     

3. On the Connection tab, click Connect. 👁 A newly configured Database Connection. (Salesforce is shown.)
   

To browse through tables exposed by the Discourse JDBC Driver, right-click a table and click "Open in New Tab."

To execute SQL queries, use the SQL Commander tool: Click SQL Commander -> New SQL Commander. Select the Database Connection, Database, and Schema from the available menus.

See the "Supported SQL" chapter in the help documentation for more information on the supported SQL. See the "Data Model" chapter for table-specific information.
