Best AI for writing SQL queries
SQL is unforgiving — a wrong join silently returns wrong data. The right model asks about your schema before guessing, uses the right join type, and explains its query so you can verify. The wrong model gives you a confident-looking query that's subtly wrong.
GPT-5.4 is the strongest SQL writer in the catalog right now — it asks clarifying questions about your schema before guessing and gets joins right.
Claude Sonnet ties on simple queries and pulls ahead on window functions / CTE-heavy analytics.
Write a Postgres query that returns the top 5 customers by total spend in the last 90 days, including their first purchase date. Schema: customers(id, name, email), orders(id, customer_id, total, created_at).
What to look for in any model
- 1Always paste the schema (CREATE TABLE) — don't make the model guess column types
- 2For analytics, ask for the query AND the explanation — verify the logic, not just the syntax
- 3Test the query on a sample before running on prod — both models hallucinate column names occasionally
- 4For migrations or destructive queries, never run model output without reading every line
