Frequently Asked Questions

How does GraphQL map to SQL?

In GraphQL, root query fields correspond to database tables, field selections correspond to SELECT columns, arguments correspond to WHERE conditions, and nested fields correspond to related tables (JOINs or separate queries).

Does it handle nested relations?

Yes. Since SQL doesn't support nested results like GraphQL does, nested field selections are converted to separate related queries with foreign key references. This matches how most GraphQL resolvers work under the hood.

Is this converter free?

Completely free, no limits. Also: SQL to GraphQL, GraphQL to MongoDB, GraphQL to REST, GraphQL Formatter.
