# SQL Pro

For the query that used to be fast

## What this does

A query is taking too long and the plan output means nothing to you. This works out where the time goes, rewrites the query, and suggests the indexes that would help. Reach for it when performance drops, when a join gets past what you can hold in your head, or when a schema needs designing or moving.

### Top 3 things it does for you

- Find out why a query is slow
- Write a complicated join or aggregation
- Design or migrate a schema

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About SQL Pro

This optimizes SQL queries, designs database schemas and troubleshoots performance problems. Use it when a query is slow, when a join or aggregation gets complicated, when database performance comes up, or when a schema needs designing or migrating.

It covers window functions, CTEs, indexing strategies, query plan analysis, covering indexes, recursive queries, interpreting EXPLAIN and ANALYZE output, and benchmarking a query before and after a change.

It also handles moving queries between database dialects, including PostgreSQL, MySQL, SQL Server and Oracle.

## Questions

### Is SQL Pro safe to install?

AIR scanned this exact version of SQL Pro and recorded 0 findings and 2 flagged items. AIR's verdict: safe. The verdict is named by the content that was read, at commit 5e8b6b8ff400, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/sql-pro.
