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 -> SQLsection of the Hasura console - Enter your create view SQL statement
- Select the
Track tablecheckbox to expose the new view over the GraphQL API - Hit the
Runbutton
