Start with the closest problem, then validate, format, optimize, and explain as needed. Quick Decision Guide Which SQL generator should you use? I have a business question, not a query Start with text to SQL to turn plain English into a first working draft. My SQL throws an error Use SQL Validator to identify syntax issues, explain them, and create a corrected version. The query works but is hard to read Use SQL Formatter to clean structure, indentation, and line breaks before review or handoff. The query is too slow or too expensive Use SQL Optimizer to improve runtime, reduce scan cost, and review index-aware suggestions. I need to understand someone else's SQL Use SQL Explainer for inline comments, summaries, and clause-by-clause explanations. I need the same query in another dialect Use SQL Converter when moving SQL between PostgreSQL, MySQL, SQL Server, Snowflake, BigQuery, and more. Recommended Workflow Move from rough idea to production-ready SQL 1 Create the first version Generate SQL from text or convert an existing query into the dialect you need. Text to SQL SQL Converter 2 Validate before execution Check syntax, catch dialect-specific issues, and fix broken SQL before it reaches production or dashboards. SQL Validator 3 Improve readability Format the query so reviewers, teammates, and future you can scan it quickly and understand intent. SQL Formatter 4 Tune performance Optimize slow or expensive SQL and review the exact changes before you ship the rewrite. SQL Optimizer 5 Explain and document Use plain-language explanations, comments, and summaries to support onboarding, reviews, and documentation.
