Customise schema with views

Table of contents

Use cases

You may want to customise your GraphQL schema to:

  • Limit scope (i.e. expose only a subset of the columns in a table)
  • Fetch derived data (aggregations like count, average, etc.) in queries

These kind of use-cases can be supported using database views.

Please see the following pages for details about the above use-cases:

Creating views

Views can be created using SQL which can be run in the Hasura console:

  • Head to the Data -> SQL section of the Hasura console
  • Enter your create view SQL statement
  • Select the Track this checkbox to expose the new view over the GraphQL API
  • Hit the Run button
