I can do SELECT and WHERE. My joins give me way too many rows and I do not know which ones are wrong.

CLAUDE · WITH THIS SKILL You get: a short task, list every customer with the total value of their paid orders, including customers who never ordered -> your query uses a LEFT JOIN with WHERE o.status = 'paid' -> the count comes back at 210 customers instead of 900 -> instead of a rewrite, the question, for a customer with no orders at all, what value does o.status hold on that row -> you answer NULL -> then the follow up, does NULL equal 'paid' -> you see the WHERE deleted the very rows the LEFT JOIN kept -> the concept named, a filter on the right table turns a LEFT JOIN into an inner one, and the fix belongs in the ON clause -> a progress block for next time.

Clause execution order taught first, because it explains most SQL bugs
LEFT JOIN, NULL behaviour and join fan out drilled until they are boring

Analysts who inherited a database, marketers tired of asking someone else for a pull, developers who copy queries without reading them, and anyone facing a SQL screen at interview.

// cosa contiene

What you're actually buying

Questo tutor AI di SQL è pensato per quando sai scrivere una SELECT con una WHERE e poco altro. Poi una join trasforma 400 ordini in 1.200, una LEFT JOIN elimina silenziosamente i clienti che stavi cercando e non sai spiegare il perché. Questo file trasforma Claude, ChatGPT o Gemini in un tutor che ti fa scrivere query e leggere i conteggi delle tue righe, invece di mostrarti la soluzione di qualcun altro.

Ti mette subito al lavoro con una query su uno schema che descrivi tu, poi insegna l’aspetto che la maggior parte dei corsi salta: l’ordine effettivo con cui il database esegue le tue clausole, FROM, poi WHERE, poi GROUP BY, poi HAVING, poi SELECT. È lì che svanisce metà di tutta la confusione su SQL. Partendo da questa base, affronta join, moltiplicazione delle righe, comportamento dei valori NULL, CTE e funzioni finestra. Quando il tuo set di risultati ha una dimensione sbagliata, non riscrive la query. Ti chiede quante righe ti aspettavi e da dove sono arrivate quelle in più.

Un solo file, identico in Claude, ChatGPT e Gemini. Incollalo in un Project, in un GPT personalizzato o in un Gem; ci vogliono circa due minuti e poi sarà tuo per sempre, senza abbonamento.

# AI SQL Tutor
KissMySkills.com | Install: paste this whole file into Claude Projects (Project instructions), a custom GPT (Instructions), a Gemini Gem, or your AI's system prompt. Then tell it what you want to learn.

## Who you are
You are a Socratic SQL tutor. Your job is to make the learner able to write a query against an unfamiliar schema and defend its row count. You are not a query generator.

Tone: plain, calm, specific. Short sentences. One idea per turn.

The one rule: you never write the finished query for a task you have set. You can show the same clause on another table, ask a question, or name the concept. You cannot hand over the answer.

## What you know about SQL
- The learnable order: SELECT and WHERE, logical execution order, filtering and NULL, aggregates with GROUP BY, INNER JOIN, LEFT JOIN, join fan out, subqueries and CTEs, window functions, then indexes and safe

Domande su questo prodotto

How does this SQL tutor work if I do not have a database yet?+

It gives you a small schema in text, three or four tables with a few rows each, and you write queries against it in the chat. If you would rather run them for real it tells you how to set up SQLite or a free Postgres instance in a few minutes. Once you have your own tables, you describe them and it teaches on those instead.

Will it just write the query for me?+

No. It is instructed never to write the finished query for a task it set you. When you are stuck it shows the same clause on a different table, or asks how many rows you expected and where the extras came from. Asking it to explain a query someone else wrote is a separate request and it will walk that line by line.

Which dialect does it teach, and does it cover window functions?+

It asks whether you are on PostgreSQL, MySQL, SQL Server, SQLite or BigQuery before it teaches anything with a date function or a string function, because those differ. Window functions are lesson nine: ROW_NUMBER, RANK, running totals and PARTITION BY, which is what most analyst interviews test.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
