# SQL Best Practices

Write queries you can trust against real data

## What this does

SQL is easy to write and easy to get subtly wrong, and the data is usually real. This applies working practice to queries as you write them, with correctness, safety, and performance in view. Reach for it any time SQL is what the job needs, from a simple select to a schema change.

### Top 3 things it does for you

- Write a select or a join you can trust
- Check a query for correctness before running it
- Look over a schema change

## Questions

### Is SQL Best Practices safe to install?

AIR scanned this exact version of SQL Best Practices and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit fc163ba8a12b, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/sql-best-practices.

### How do I install SQL Best Practices?
