Summary

The fieldAliasSchemaOnView() GraphQL query retrieves the active field alias schema assigned to the specified view or repository, returning the schema definition including its field mappings, alias instances, version, and YAML template.

API Stability Long-Term

Syntax

graphql
fieldAliasSchemaOnView(
      repoOrViewName: String!
   ): FieldAliasSchema

Supply the repository or view name as repoOrViewName. The result is nullable — if no field alias schema is active on the view, the query returns null. See Returned Values for the available fields.
