SQLFlash vs Raw Query

SQLFlash rewrites slow queries, recommends indexes, and explains every change in plain language. You paste a statement or upload a MyBatis XML mapping, and it returns an optimized version with a diff viewer, query plan breakdown, and performance score. It supports MySQL, PostgreSQL, Oracle, SQL Server, MariaDB, TiDB, and other relational engines without needing database credentials.

Most SQL tuners either need live access to your database or hand you a rewritten query with no context. SQLFlash takes the opposite approach: it works on the text alone, uses a two-stage rule filter to match optimization patterns, and documents each rewrite step in a journal you can audit. That trade-off means you validate results in your own test environment, but you never grant read access to production data.

Developers, DBAs, and platform teams use SQLFlash when legacy queries slow down apps, when MyBatis XML files pile up without review, or when a database migration changes execution plans overnight. Case studies on the site cover e-commerce product pages, banking dashboards, restaurant order history, and school course progress queries.

Raw Query lets you chat with Postgres, MySQL, and MariaDB using plain English instead of writing SQL by hand. Paste a database connection string, ask questions like who joined your Pro plan last week, and Raw Query returns answers or CSV exports from a browser or mobile device.

Compared with BI dashboards that need setup and SQL clients that assume query fluency, Raw Query targets quick ad hoc questions from founders and analysts. Postgres connections support inserts and updates with confirmation prompts, while MySQL and MariaDB connections focus on read queries, so teams on Postgres get broader write access.

Raw Query fits solo founders, developers avoiding one-off internal tools, and BI users who want answers without learning SQL syntax. The free plan includes 300 successful queries per month across two databases, and paid tiers raise query limits, seats, and support priority up to unlimited seats on the Team plan.
