How every lesson works
Say It Out Loud
Every query, formula, or chart is broken down piece by piece into plain language. Read it back to yourself — in whatever language you think in — and if you can explain what each part is doing, you own it. Works the same whether English is your first language or your fifth.
SELECT name FROM customers WHERE status = 'active';
Give me the names of customers whose status is "active".
SELECT name → get the name column
FROM customers → from the customers table
WHERE status = 'active' → only rows where status is active
