Great news! We've added support for Check constraints, allowing you to set rules on your table fields to enforce data quality—such as ensuring quantities are above zero or ratings stay within a range.

Here's a simple DBML example:

Table orders {
  id integer [pk, increment]
  price decimal [not null, check: `price > 0`]
  discount decimal [not null, default: 0, check: `discount >= 0`]

  checks {
    `discount < price` [name: 'valid_discount']
  }
}

Previously, these had to go in notes, which meant they could disappear during SQL imports or exports. Now, define them right in DBML, import and export with accuracy, and view them in your ER diagrams and docs for clearer sharing.

It's a simple way to make your databases more reliable and your documentation more informative. Update your diagrams now and start applying Check constraints!

We're excited to announce support for importing CSV files to generate DBML!

You can now upload a CSV file and automatically generate DBML table code following the CSV structure. This feature makes it easy to visualize database schemas from existing CSV files.

To get started, simply choose the Import from CSV option in your diagram.

We're excited to announce Diagram Views, a new feature that lets you create multiple customized views of your database diagram.

Now, you can filter out specific tables to highlight only the parts relevant to your current focus—whether it's a particular domain, process, or team discussion—all from the same underlying database structure that defined in your DBML code.

Why you’ll like it:

• No more overwhelming diagrams with hundreds of tables.
• Easily switch between views to share targeted insights, like a "Customer" for only customer-related tables, or an "Orders" view for sales workflows.
• Define one database structure and reuse it across multiple views.

Try it now:

• Open a diagram.
• Toggle table search panel (you can also press Cmd / Ctrl + F).
• Add a new view, and select your tables.

Note: Saving multiple views is a Personal Pro feature. On the Free plan, you can only filter tables and save these settings in the default view.

We’re excited to announce a powerful new feature in DBML — TablePartial!

Now you can define reusable sets of fields, settings, and indexes and inject them into multiple tables with a simple ~partial_name syntax.

Why you’ll like it:

• ✅ Write cleaner, DRY-er (Don’t Repeat Yourself) schema definitions.
• ♻️ Reuse common fields like timestamps and user metadata.
• ⚙️ Maintain consistency across your entire database with ease.

Start using TablePartial today to simplify your DBML projects and speed up your workflow!
