Next Level SQL

Hi, my name is Derek and I’m the proud father of Next Level SQL and 4 young kids. I have 5 years of experience as a data scientist who has spent most of his time thinking about, coding, and reviewing SQL. I think Next Level SQL is the best way to learn how to write SQL to solve real world business problems.

If you have benefitted from the platform, please consider donating to support the development of more datasets for you to practice SQL on. If we hit the fundraising goal, I’ll share a new dataset within 2 weeks after hitting the goal. (Otherwise, I’ll share once I find the time to develop.)
