Connect to IBM Cloud Object Storage data and execute queries in the Squirrel SQL Client.
The CData JDBC Driver for IBM Cloud Object Storage enables you to execute queries to IBM Cloud Object Storage data in tools like Squirrel SQL Client. In this article, you will create a JDBC data source for IBM Cloud Object Storage data and execute queries.
Add the JDBC Driver for IBM Cloud Object Storage
Follow the steps below to add the driver JAR.
- In Squirrel SQL, click Windows -> View Drivers.
- Click the plus icon to open the Add Driver wizard.
- In the Name box, enter a user-friendly name for the driver; for example, CData JDBC Driver for IBM Cloud Object Storage.
- In the Example URL box, enter jdbc:ibmcloudobjectstorage:
- In the Extra Class Path tab, click Add.
- In the file explorer dialog that opens, select the JAR file for the driver, located in the lib subfolder of the installation directory.
- Click List Drivers to populate the Class Name menu with the class name for the driver, cdata.jdbc.ibmcloudobjectstorage.IBMCloudObjectStorageDriver.

Define Connection Properties
Follow the steps below to save connection properties in the driver alias.
- Click Windows -> View Aliases.
- In the pane that lists the aliases, click the plus icon.
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 IBM Cloud Object Storage Source.
- Driver: Select the CData JDBC Driver for IBM Cloud Object Storage.
- URL: Enter jdbc:ibmcloudobjectstorage:
- If you want to define any additional properties, click Properties.
- In the Driver properties tab of the dialog that appears, select the Use driver properties checkbox.
- In the Specify column, select the checkboxes for the required connection properties.
Register a New Instance of Cloud Object Storage
If you do not already have Cloud Object Storage in your IBM Cloud account, follow the procedure below to install an instance of SQL Query in your account:
- Log in to your IBM Cloud account.
- Navigate to the page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.
Connecting using OAuth Authentication
There are certain connection properties you need to set before you can connect. You can obtain these as follows:
API Key
To connect with IBM Cloud Object Storage, you need an API Key. You can obtain this as follows:
- Log in to your IBM Cloud account.
- Navigate to the Platform API Keys page.
- On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
- In the pop-up window, specify the API Key name and click "Create". Note the API Key as you can never access it again from the dashboard.
Cloud Object Storage CRN
If you have multiple accounts, you will need to specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:
- Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
- Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.
Connecting to Data
You can now set the following to connect to data:
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- ApiKey: Set this to your API key which was noted during setup.
- CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the connector attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than Cloud Object Storage account.
When you connect, the connector completes the OAuth process.
- Extracts the access token and authenticates requests.
- Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
Below is a typical connection string:
jdbc:ibmcloudobjectstorage:ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;
- In the dialog that appears after you click OK, click connect to test the connection.
Discover Schemas and Query IBM Cloud Object Storage Data
After the metadata has loaded, a new tab for the IBM Cloud Object Storage 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:
SELECT Key, Etag FROM Objects WHERE Bucket = 'someBucket'
