This is a repository of solutions to SQL Practice Problems: 57 beginning, intermediate, and advanced challenges for you to solve using a “learn-by-doing” approach.

The test database on which all the queries are made is the Northwind sample database. The SQL for the same can be found here.

I used a locally run Hasura instance to view the tables and ran SQL queries using its Raw SQL view. To setup a Hasura GraphQL Engine locally with a posgtres database, use the docker-compose file which has the required configurations.
