Can it generate complex queries with multiple JOINs?

Yes. Describe your tables, their relationships, and what data you need. For example: 'Get total revenue per customer from an orders table joined to a customers table, filtered to the last 30 days, sorted by revenue descending.'

Does it support window functions and CTEs?

Yes. Ask for running totals, rank by partition, lag/lead comparisons, or multi-step CTEs and the AI will generate the correct syntax with an explanation.

What if my generated query has an error?

Paste the error message back and ask the AI to fix it. It will diagnose the issue and provide a corrected query with an explanation of what was wrong.

Can it reverse-engineer existing SQL to explain what it does?

Yes. Paste an existing query and ask 'What does this query do?' for a plain English explanation of every clause and join.
