Database diagrams

Enable the Database Tools and SQL plugin

This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in GoLand 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.

Database diagrams graphically show the structure of the database and relations between database objects. You can generate a diagram for a data source, a schema, or a table. To create relations between database objects, consider using primary and foreign keys.

You can save the generated diagrams in two formats: UML and PNG. The UML format is an internal format developed specifically for GoLand. It is not supported by other products. If you want to share the created diagram, consider using PNG.

Also, you can build execution plans. An execution plan is a set of steps that were used to access data in a database. For more information about creating an execution plan, refer to Visualize a query plan.

Generate a diagram for a database object

  • In the Database tool window ( View | Tool Windows | Database) , right-click a database object and select Diagrams | Show Diagram.

Pan and zoom

  • To pan and zoom the diagram, use your touchpad, scroll bars or the mouse wheel for vertical scrolling and Shift + mouse wheel for horizontal scrolling. You can also use Shift + mouse wheel for zooming.

  • To use the magnifier tool, keep the Alt key pressed, and hover over the desired areas of the diagram. Use the mouse wheel to extra zoom the diagram area within magnifier tool.

Apply colors to diagram objects

  1. In the Database tool window ( View | Tool Windows | Database) , right-click an object and select Tools | Set Color….

  2. Select a color and click OK. Refresh the diagram to apply the color by clicking the Refresh button ().

Export diagrams

In GoLand, you can export a diagram in various formats to file, to clipboard, and open it in a web editor. You can also print a diagram and save it as an image. To do that, use the corresponding actions in the context menu of your diagram.

Open diagrams in web editors

Copy diagrams to clipboard

  • To copy your diagram to clipboard, right-click the diagram, navigate to Export Diagram | Copy to Clipboard, and select the format.

    Alternatively, click the Export Diagram button (Export Diagram icon) on the diagram toolbar, and select the format in the corresponding submenu.

    The supported formats are as follows:
