SQLReview

Review SQL code for anti-patterns, performance issues, and correctness bugs

Code & DevelopmentFreemium

SQLReview analyzes SQL queries and stored procedures for anti-patterns including SELECT *, implicit type conversions that prevent index use, correlated subqueries that could be joins, and NULL-unsafe comparisons. The tool understands dialect-specific behavior for PostgreSQL, MySQL, SQL Server, and Oracle, and flags queries that will produce different results across databases. It estimates query cost from table statistics and suggests specific rewrites. Database teams use it as a code review assistant for SQL-heavy codebases.
