Connect to IBM Cloud Object Storage Data in DBVisualizer

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

Create a New JDBC Data Source for IBM Cloud Object Storage Data

Follow the steps below to use the Driver Manager to provide connectivity to IBM Cloud Object Storage data from DBVisualizer tools.

1. In DBVisualizer, click Tools -> Driver Manager -> Create a New Driver.
2. Enter a name for the data source.
3. Enter the following in the URL Format box: jdbc:ibmcloudobjectstorage:
   The DBVisualizer Driver Manager.
4. In the User Specified tab, click the Open File button and select the cdata.jdbc.ibmcloudobjectstorage.jar file, located in the lib subfolder of the installation directory.
5. In the Driver Class menu, select the IBMCloudObjectStorageDriver class, cdata.jdbc.ibmcloudobjectstorage.IBMCloudObjectStorageDriver.

Define the Connection to the JDBC Data Source

Follow the steps below to save connection properties in the JDBC URL.

1. In the Database tab, right-click the Database Connection node and click Create a Database Connection.

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: Select the driver you just created.

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

     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:

     1. Log in to your IBM Cloud account.
     2. 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:

     1. Log in to your IBM Cloud account.
     2. Navigate to the Platform API Keys page.
     3. On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
     4. 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.

     1. Extracts the access token and authenticates requests.
     2. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.ibmcloudobjectstorage.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:ibmcloudobjectstorage:ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;
   • Database UserId: The username to use to authenticate to IBM Cloud Object Storage.
   • Database Password: The password to use to authenticate to IBM Cloud Object Storage.

3. On the Connection tab, click Connect.

To browse through tables exposed by the IBM Cloud Object Storage 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.
