Connect to an Oracle database

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 () in the toolbar. Navigate to Data Source and select Oracle.
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, see 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.
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 GoLand 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.
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, see Add a user driver to an existing connection.
If there is no Download missing driver files link, then you already have the required drivers.
Specify the database connection details. Alternatively, paste the JDBC URL in the URL field.
SID
Service Name

Long
URL only
1. In the Host field, type your server address.
2. In the Port field, type the port of Oracle. The default port is 1521.
  note
  Real port numbers might be different on your system. Verify that you use a correct port number with your database administrator, server settings, or hosting provider.
3. In the SID field, specify a unique name of Oracle instance (a process that runs on the workstation).
  For more information, see 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.
7. In the URL field, GoLand 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.
1. In the Host field, type your server address.
2. In the Port field, type the port of Oracle. The default port is 1521.
  note

3. In the Service field, enter the alias to an Oracle instance that you want to use.
4. From the Driver list, select the Oracle JDBC driver mode to use with your connection:

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.
7. In the URL field, GoLand 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_alias>
  Example: jdbc:oracle:thin:@//127.0.0.1:1521/XE
  For more information about the URL format, refer to the Oracle official documentation.
1. In the TNSADMIN field, specify a path to the folder with tnsnames.ora. Alternatively, click the Open icon () and navigate to it.
  For more information, see the Connection settings and DBMS-specific properties.
2. In the TNS name field, specify what service name to use if you have more than one service.
  For more information, see the DBMS-specific General tab reference.

For the reference information about connection settings and properties on the General and other tabs of Data Sources and Drivers dialog (ShiftEnter), see Connection settings and DBMS-specific properties.
Ensure that the connection to the database can be established using the provided details. To do that, click the Test Connection link at the bottom of the connection details area.
In case of any connection issues, refer to the Cannot connect to a database page.
(Optional) By default, only the default schema is introspected and available to work with. If you also want to work with other schemas, in the Schemas tab, select them for the introspection.
Click OK to create the data source.
Find your new data source in the Database tool window (Alt01) .
- To learn more about the Database tool window, see the corresponding reference topic.
  tip
  To see more schemas under your new data source node, click the N of M button and select the ones you need. GoLand will introspect and show them.
- To learn how to work with database objects in GoLand, see Database objects.
- To write and run queries, open the default query console by clicking the data source and pressing F4.
- To view and edit data of a database object, open Data Editor and Viewer by double-clicking the object.
