Enable the Database Tools and SQL plugin

This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in CLion by default. If the relevant features aren't available, make sure that you didn't disable the plugin.

  1. Press Control+Alt+S to open the IDE settings and then select Plugins.

  2. Open the Installed tab, find the Database Tools and SQL plugin, and select the checkbox next to the plugin name.

Official documentation and software

This topic presents a general procedure on how you can create a data source for the connection to your Oracle database in CLion, and run a test connection. It is assumed that you already have the necessary prerequisites and the database is up and running. For example, if you want to run a database on your machine and connect to that database, the corresponding DBMS software must be installed on the machine first.

Connect to an Oracle database

  1. To connect to the database, create a data source that will store your connection details. You can do this using one of the following ways:

    • From the main menu, navigate to File | New | Data Source and select Oracle.

    • In the Database tool window ( View | Tool Windows | Database) , click the New icon (the New icon) in the toolbar. Navigate to Data Source and select Oracle.

    Create a new data source
  2. In the General tab of Data Sources and Drivers dialog right pane, specify the driver and connection type.

    1. From the Driver list, select the JDBC driver for your connection.

      For Oracle, the supported drivers are Oracle and Oracle for 9.X, 10.X, 11.1. For more information about driver types, refer to Oracle JDBC FAQ.

    2. From the Connection type list, select the connection type depending on the connection details that you have:

      • SID: to use a unique name of an Oracle instance (a process that runs on the workstation).

      • Service name: to use an alias to an Oracle instance (or many instances).

      • TNS: to use tnsnames.ora configuration file.

      • Long: to use an extended JDBC URL format with advanced parameters.

      • URL only: connect by using only the URL.

      For the URL only connection type, the JDBC URL that you enter is used as is.

      For the other connection types, the JDBC URL is broken down into connection details. You can either specify them separately and use the automatically generated URL, or you can enter the URL directly in the corresponding field.

    General tab of the Data Sources and Drivers dialog
  3. Check if there is a Download missing driver files link at the bottom of the connection settings area. Click this link to download drivers that are required to interact with a database. For a direct download link, refer to the JetBrains JDBC drivers page.

    You can find the downloaded JDBC drivers in the CLion configuration directory.

    The IDE does not include bundled drivers in order to have a smaller size of the installation package and to keep driver versions up-to-date for each IDE version.

    The Download missing driver files link

    You can also use your drivers for the database instead of the provided ones. For more information about connecting to a database with your driver, refer to Add a user driver to an existing connection.

    If there is no Download missing driver files link, then you already have the required drivers.

  4. Specify the database connection details. Alternatively, paste the JDBC URL in the URL field.

    1. In the Host field, type your server address.

    2. In the Port field, type the port of Oracle. The default port is 1521.

    3. In the SID field, specify a unique name of Oracle instance (a process that runs on the workstation).

      For more information, refer to the DBMS-specific General tab reference.

    4. From the Driver list, select the Oracle JDBC driver mode to use with your connection:

      • Thin: the driver connects to the server directly.

      • OCI and OCI8: the driver uses native libraries to connect to the server.

    5. From the Authentication list, select the authentication method that you want to use to authenticate the connection. The following options are available:

      • User & Password: by using your login and password.

      • Kerberos: use Kerberos for authentication. Requires a Kerberos server and authentication with kinit

      • No auth: authentication is not required.

    6. In User and Password fields, type your user credentials.

      To use no password, leave the Password field empty.

      To delete a once entered password, right-click the Password field and select Set Empty.

      the Set Empty context menu action
    7. In the URL field, CLion generates the JDBC URL automatically using the values of other connection settings.

      If you need to use a JDBC URL with certain additional settings, paste it in the URL field. The general URL to use is as follows:

      • Format: jdbc:oracle:thin:@<host_address>:<port_number>:<instance_name>

      • Example: jdbc:oracle:thin:@127.0.0.1:1521:XE

      For more information about the URL format, refer to the Oracle official documentation.
