Learn SQLwhile you type it.
SQL mastery and typing speed — trained at the same time. Real queries, real databases, real results.
Three steps to fluent SQL.
No videos to sit through. Pick a query, type it for real, watch your skills compound.
Pick a lesson
Choose from real-world SQL queries — fundamentals, joins, subqueries, and window functions.
Type the query
Type the actual SQL character by character. Get instant feedback on speed and accuracy as you go.
Track your growth
Watch your WPM and accuracy climb, level up, earn XP, and see how you stack up on the leaderboard.
Four paths. One goal.
Start with SELECT and end with window functions. Every lesson is a real query you'll actually use.
SQL Fundamentals
Master the building blocks of SQL while building typing speed on real queries.
SQL Power Queries
Unlock aggregations, joins, and conditional logic to write production-grade SQL.
Advanced SQL
CTEs, subqueries, and window functions used by senior data engineers.
Database Mastery
Execution plans, indexes, procedures, and query optimization for DBAs.
Not just SQL.
Master the frameworks that power production apps — TypeORM, Prisma, and Drizzle. Same engine, real query patterns.
const orders = await dataSource

.innerJoinAndSelect('order.user', 'user')
.where('order.status = :status', {
status: 'pending',
})
.orderBy('order.createdAt', 'DESC')
.take(10)
