SQL Workshop

Support materials for a training about SQL/MySQL we do at Flywire from time to time.

Getting Started

We've prepared a container with MySQL that you can bring up with make up and then create the schema and load some test data on it:

make up   # wait few seconds for it to start

make schema seed

For the exercises, you can write your queries in scratch.sql and run them automatically with make - it's the default target. We recommend you to read the Makefile targets to understand how mysql executable is executed inside the container.

You can also run MySQL Shell by doing make shell. Alternativelly, MySQL will be available at port 3306 - user root, password password.

Other targets that you may find interesting:

make slides          # bring up slides used in the workshop
make drop            # drop all the tables
make clean           # clean all CSV seed files
make generate_data   # generate CSV seed files

Slides and exercises

There are some exercises prepared for you, they can be found by doing make slides in a terminal. Solutions are in the exercises folder.
