How to connect to HCL Domino Data with Squirrel SQL client

The CData JDBC Driver for HCL Domino enables you to execute queries to HCL Domino data in tools like Squirrel SQL Client. In this article, you will create a JDBC data source for HCL Domino data and execute queries.

Add the JDBC Driver for HCL Domino

Follow the steps below to add the driver JAR.

1. In Squirrel SQL, click Windows -> View Drivers.
2. Click the plus icon to open the Add Driver wizard.
3. In the Name box, enter a user-friendly name for the driver; for example, CData JDBC Driver for HCL Domino.
4. In the Example URL box, enter jdbc:domino:
5. In the Extra Class Path tab, click Add.
6. In the file explorer dialog that opens, select the JAR file for the driver, located in the lib subfolder of the installation directory.
7. Click List Drivers to populate the Class Name menu with the class name for the driver, cdata.jdbc.domino.DominoDriver.

Define Connection Properties

Follow the steps below to save connection properties in the driver alias.

1. Click Windows -> View Aliases.
2. In the pane that lists the aliases, click the plus icon.

3. In the Add Alias wizard that opens, the following fields are required for the JDBC driver:

   • Name: Enter a name for the alias; for example, CData HCL Domino Source.
   • Driver: Select the CData JDBC Driver for HCL Domino.
   • URL: Enter jdbc:domino:
4. If you want to define any additional properties, click Properties.
5. In the Driver properties tab of the dialog that appears, select the Use driver properties checkbox.
6. In the Specify column, select the checkboxes for the required connection properties.

   Prerequisites

   The connector requires the Proton component to be installed. Normally, Proton is distributed as part of the AppDev pack. See the HCL documentation for instructions on acquiring and installing Proton or the AppDev pack.

   Once the Proton service is installed and running, you will also need to create a user account and download its Internet certificate. This certificate can be used to set the connector certificate connection properties.

   Authenticating to Domino

   • Server: The name or IP address of the server running Domino with the Proton service.
   • Port: The port number that the Proton service is listening on.
   • Database: The name of the database file, including the .nsf extension.
   • SSLClientCertType: This must match the format of the certificate file. Typically this will be either PEMKEY_FILE for .pem certificates or PFXFILE for .pfx certificates.
   • SSLClientCert: The path to the certificate file.
   • SSLServerCert: This can be set to (*) if you trust the server. This is usually the case, but if you want to perform SSL validation, you may provide a certificate or thumbprint instead. See the documentation for SSLServerCert for details.

   Additional Server Configuration

   The connector supports querying Domino views if any are defined. Before views can be queried by the connector they must be registered with the design catalog.

   Please refer to the Catalog Administration section of the AppDev pack documentation for details on how to do this.

   Below is a typical connection string:

   jdbc:domino:Server=https://domino.corp.com;Database=names.nsf;Port=3002;SSLClientCertType=PEMKEY_FILE;SSLClientCert=full_path_of_certificate.pem;SSLServerCert=*
7. In the dialog that appears after you click OK, click connect to test the connection.

Discover Schemas and Query HCL Domino Data

After the metadata has loaded, a new tab for the HCL Domino data source is displayed. On the Objects subtab, you can discover schema information, such as the available tables and views.

To view table data, select the table on the Objects tab. The table data is then loaded in a grid on the Content tab.

To execute an SQL query, enter the query on the SQL tab and then click Run SQL (the runner icon). For example:
