Does this prompt need a real database connection?

No. It creates a learning draft with anonymous sample tables without asking for real connections, credentials, or private tables.

Is this prompt suitable for beginners?

Yes. If beginner level is selected, it can explain topics such as SELECT, WHERE, JOIN, and GROUP BY with simple examples.

Does this prompt teach delete or update commands?

The main focus is safe reading and query understanding. If needed, data-changing commands can be mentioned only as general caution notes.

Can it be used for SQL Server, PostgreSQL, or MySQL?

Yes. If the user provides the database style, it can mark syntax differences as points to check.

SQL basic query learning prompt

What is this prompt used for?

This prompt explains basic SQL query logic for beginners with simple examples. It creates a structured learning draft for SELECT, WHERE, JOIN, GROUP BY, ORDER BY, COUNT, and SUM using anonymous tables.

Who is it for?

It is useful for SQL beginners, users who want to understand database queries, learners studying reporting query logic, and people starting data analysis or software development.

When should you use it?

It can be used when learning SQL queries from scratch, understanding how to join two tables, or practicing filtering and grouping queries with sample tables.

Example use case

A user may want to learn SELECT, WHERE, JOIN, and GROUP BY using product and order tables. This prompt creates sample tables, explains queries line by line, shows expected results, and prepares mini exercises.

Tips for better results

Instead of writing only 'teach me SQL', a clearer goal such as 'explain SELECT, WHERE, and JOIN logic for a beginner using products and orders tables line by line' can create a more useful output.

Short learning goal summary

The goal of this lesson is to learn basic data reading in SQL, filter with WHERE, and understand how to combine two tables with INNER JOIN.

Anonymous sample tables to use

products table: product_id, product_name, category, unit_price orders table: order_id, product_id, quantity, order_date

Sample query

select orders.order_id, products.product_name, products.category, orders.quantity from orders inner join products on orders.product_id = products.product_id where products.category = 'Books' order by orders.order_id;

Line-by-line query explanation

The select section defines which columns will be shown. orders.order_id returns the order number. products.product_name returns the product name. inner join products combines two tables using the shared product_id field. where products.category = 'Books' filters only products in the Books category. order by orders.order_id sorts the result by order number.

Example result logic

The query result shows only orders for products in the Books category. Each row contains order number, product name, category, and quantity. The exact result depends on the sample data.

Common beginner mistakes

Writing the table name incorrectly can stop the query from running. Choosing the wrong column in the JOIN condition can create unexpected results. Forgetting quotation marks around text values in WHERE can create an error. The ORDER BY field should be checked based on the table structure.

Mini exercises

1. Write a query that returns only products in the Electronics category. 2. Sort the result by product name. 3. Add the unit_price column to the SELECT section. 4. Explain in your own words which columns the JOIN condition matches. 5. Predict how the result changes if the WHERE filter is removed.

Mini quiz

1. What does SELECT do? 2. What is WHERE used for? 3. Why is INNER JOIN used? 4. What does ORDER BY do? 5. Why is the shared column important in a JOIN condition?

Final checklist

Are table names correct? Are column names correct? Does the JOIN condition make sense? Does the WHERE filter return the expected result? Is the query read-only? Has syntax been checked for the database type?
