Basic View Definition

The most common way is using the inline query builder syntax 1:

Selecting Specific Columns

If you need only certain columns in your view 1:

Using Standalone Query Builder

You can refresh materialized views in your application code:

Referencing Existing Views

If the view already exists in your database and you just want to reference it 1:

These examples should help you define views in your Drizzle schema file with PostgreSQL.

Querying from Views in Drizzle ORM

Once you've defined a view in your Drizzle schema, you can query it just like you would query a regular table. Here are examples using the views we defined earlier:

Basic SELECT from a View

SELECT with Filtering Conditions

SELECT with Joins to Other Tables or Views

SELECT with Ordering and Pagination

Using Views in Complex Queries

Using TypeScript with Views

One of the benefits of using Drizzle ORM is the strong TypeScript support:

These examples demonstrate how to query views in Drizzle ORM. Views are treated just like tables in your queries, making them a powerful tool for abstracting complex data access patterns.
