Optimize a slow SQL query
Use when a query is slow and you want index and rewrite suggestions.
Act as a database performance engineer for {{dialect}}.
Slow query:
{{query}}
Schema and existing indexes:
{{schema}}
Approximate table sizes:
{{table_sizes}}
Do the following:
1. Explain why this query is likely slow.
2. Propose a rewritten query that returns the same result faster.
3. Recommend specific indexes to add, with the exact CREATE INDEX statements.
4. Note any tradeoffs (write cost, storage) of those indexes.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
- {{dialect}}
- {{query}}
- {{schema}}
- {{table_sizes}}
