Data sources

Enable the Database Tools and SQL plugin

This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in PyCharm by default. If the relevant features are not available, make sure that you did not disable the plugin.

  1. Press Ctrl+Alt+S to open 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.

Data source is a connection configuration. It stores a list of connection details that are used to establish connection to a database. For example, host, port, database name, driver, SSH and SSL configuration settings, and so on. In data source settings, you can also select databases and schemas for introspection and display in Database tool window, and change the driver for your connection.

You can configure your data sources in the Data Sources and Drivers dialog (Ctrl+Alt+Shift+S) . To access the dialog, in the Database tool window (View | Tool Windows | Database) , click the Data Source Properties button (the Data Source Properties button) on the toolbar.

Data source with connection details for a PostgreSQL database

You can see the list of created data sources in the Database tool window (View | Tool Windows | Database) . Data sources with an active connection to a database are marked with a green dot in the corner of their icons.

Data sources in the Database tool window

In PyCharm, you can create the following data sources:

  • Database data sources: connection configurations for the operational databases that contain data.

    For different database vendors, PyCharm provides complete support and basic support. Complete support of a database vendor includes such features as enhanced code completion and better retrieval of database objects (introspection). All the inspections, quick-fixes, and other coding assistance features are also available. Whereas basic support has limited features available.

    For more information on the support types, refer to the Other databases topic.

  • Data Definition Language (DDL) data sources: SQL files that contain data definition language statements (refer to DDL data sources).

Create a data source

To connect to a database and start working with it, create a data source that will contain the connection details and specify those details for the database that you are connecting to.

Configure display options for data sources

You can group, assign a color, and filter objects in the Database tool window (View | Tool Windows | Database).

Customize the view of objects in the Database tool window

  • To group, enable, or sort data sources, click the Options icon (the Show Options menu icon) on the header of the Database tool window and select the necessary options.

    In the Database tool window (View | Tool Windows | Database) , the view of the data source changes instantly.

    For more information about the database tree view options, refer to View Options.

Group data sources in folders

  • In the Database tool window (View | Tool Windows | Database) , select the necessary data source and press F6. Alternatively, right-click a data source and select Move to Folder.

    • If you do not have any folders, you will see the New Folder dialog. In the text field, type the folder name. You can use a forward slash (/) to define nesting. For example, the QA/Quick name will create the Quick folder inside the QA folder.

      Create a new folder to group data sources
    • If you have folders with grouped data sources, you will see the Move to Folder dialog. To create a new folder, select New Folder. To remove a data source from the folder, select Root folder.

      Move a data source to a folder

    Also, you can use Ctrl+C, Ctrl+V, and Ctrl+X to copy, paste, and cut your data sources between folders. If you cut and paste a data source inside one project, it will be moved. No password is required. But the password is required in all the other cases. The cut operation can be undone by using Ctrl+Z.

Share data sources

Data sources in PyCharm are available at two levels: project and global. The project level means that you can access a data source only from the project where this data source was created initially. At the global level, a data source is available for other projects. By default, a data source is available at the project level.

To share a data source between different projects inside your IDE, you need to move the data source to the global level.

You can copy a data source if you need to use the same data source in another project but have different requirements for it, such as its accessibility level (project or global), the user, database connection and schema settings, and so on.

Share data sources between projects

  1. In the Database tool window (View | Tool Windows | Database) , click the Data Source Properties button (the Data Source Properties button).

  2. In the Data Sources and Drivers window, click the Make Global icon (the Make                 Global icon) to make the data source available at the global level. Click the the Make Global icon icon again to change the level to project.

    The project level means that you can access a data source only from the project where this data source was created initially. At the global level, a data source is available for other projects. By default, a data source is available at the project level.

    Share data sources between projects

Share data sources between different IDE instances

You can copy information about a data source to the clipboard in the XML format.

The resulted XML does not include password information, unless it was provided within a JDBC URL for the URL only connection type. For more information about this connection type, refer to Data Source and Drivers dialog reference topic.

You can send the XML snippet to another IDE (in a messenger or by email) and import it.

  1. In the Database tool window (View | Tool Windows | Database) , select data sources that you want to copy.

  2. Press Ctrl+C. Alternatively, right-click the selection and navigate to Copy/Paste | Copy Data Source.

  3. On another workstation, click View | Tool Windows | Database.

  4. In the Database tool window, click the New icon (the New icon), select Import from Clipboard. Alternatively, right-click the Database tool window and select Copy/Paste | Paste Data Source (or press Ctrl+V).

You can delete a data source in one of the following ways:

  • To delete the data source using its context menu, in the Database tool window (View | Tool Windows | Database) , right-click the data source that you want to delete and select Delete Data Source.

  • To delete a data source in the Data Sources and Drivers dialog, follow these steps:

    1. Open data source properties. You can open data source properties by using one of the following options:
