The path to "SQL Jissen Nyumon (A Practical Introduction to SQL)"
Here is the reading path leading up to this book, derived from its dependencies and ordered from the fundamentals.
The path so far (1 books)
Why read this first: After you can write correct SQL, the next lens is reading the execution plan (EXPLAIN) to understand why a query is slow. This book starts tuning from the execution plan, so reading it right after the basics grows you from 'can write SQL' to 'can write fast SQL'.
