YOUR DECISION GUIDE
Fit: query practice with PostgreSQL
Consider this if you want to work through database questions in PostgreSQL. Compare CS50 SQL if you also want a course organised around database design concepts and a final project.
Our suggested first milestone is to write a query, predict its row count and verify the result. That is more useful than memorising a command without checking what it returns.
A study routine for SQL
Keep a notebook of questions and queries. When adding a join, inspect whether the number of rows changed unexpectedly. Try records with missing or repeated values so your answers do not depend only on tidy sample data.
After a challenge, explain why another plausible query would give a different result. This is independent practice advice.
