Use the SQL plugin to create an entity relationship diagram

This plugin should be used as-is, as an unsupported example for developers.

Insert SQL code using the SQL plugin to automatically generate entity shapes, including their attributes, as well as their primary and foreign keys. To complete your entity relationship diagram, connect the entities together and set the connector ‘arrows’ to describe their relationships.

Create an ER diagram from SQL code

As SQL and MySQL are the most popular languages used to program and work with relational database systems, has made it easy to automatically create your diagrams from your code.

  1. Click Arrange > Insert > From SQL.
  2. Copy and paste your SQL code into the dialog, then click Insert MySQL or Insert SQL Server, whichever matches the code you just pasted.
    Insert SQL code then select which SQL it is to create an ER diagram automatically
  3. Your SQL code is converted into entities containing the attributes, as well as the primary and foreign keys your code defines.
  4. Connect the entities and choose the ‘arrow’ shape that defines the relationship.
    Entity shapes are automatically created based on your SQL code - draw connectors to finish your ER diagram

Tip: To see the various entity relationship styles, enable the Entity Relation shape library (via More Shapes in the left panel), then hover over the various connector shapes to show their descriptions.
Hover over connector shapes in the Entity Relation library to see them more clearly
