ERD Viewer

The ERD viewer generates an interactive Entity Relationship Diagram directly from your database schema. It shows tables, columns, and foreign key relationships in a visual layout.

Opening the ERD

Open the command palette with Cmd+K (Mac) or Ctrl+K (Windows/Linux).
Search for View ERD Diagram.
The diagram generates from your current connection.

Navigating the diagram

Pan: click and drag the background.
Zoom: scroll to zoom in and out, or use the zoom controls.
Search: use the search field to find tables by name.
Schema filter: show or hide specific schemas to focus on the tables you care about.

Each table node displays its columns with data types, and badges for primary keys and foreign keys. Foreign key relationships appear as connections between tables.

The toolbar shows the total table count and relationship count for quick reference.
