Queries based on 'query' type from Schema or dynamic queries

Is there a way to dynamically build queries based on schema available, schemas have special type 'query', was looking for a way to build query for the client based on the queries available on schema, currently all the example I can find need to have query build during compile time, my requirement is to build queries in runtime, based on the schema query type provided, where user only knows the query name.

Any help is appreciated.

Thank you!
