Write & review SQL with AI

Why this skill matters

Generated SQL can run without errors and still return the wrong answer.

What to learn

• Give the assistant the schema and business definitions
• Explain each join and filter before trusting a query
• Compare results with a figure you already know

Before you begin

Basic SELECT, JOIN and GROUP BY

PUT IT INTO PRACTICE

Build a work sample

Ask an assistant for a monthly revenue query on a sample database. Then check row counts, null handling and duplicate joins against a hand-calculated total.

Evidence of progress

A reviewed query with a note of what was checked and one error that was corrected.
