❓ Frequently Asked Questions
Why should I format my SQL queries? Unformatted SQL is a major pain point in database development. Poorly formatted queries are hard to read, debug, and maintain. Our formatter instantly transforms messy SQL into clean, professional code that follows industry best practices. This reduces errors, speeds up code reviews, and makes collaboration easier. How does the SQL validation feature work? The validator performs real-time syntax checking as you type, catching common errors like unmatched parentheses, missing commas, incorrect keywords, and invalid table references. It understands dialect-specific syntax rules, so a query valid in MySQL but not in PostgreSQL will be flagged appropriately. This prevents runtime errors and saves debugging time. Can I convert SQL queries between different database systems? Yes! One of the biggest pain points in database migration is syntax differences between systems. Our converter automatically translates queries between MySQL, PostgreSQL, SQLite, Oracle, and SQL Server. It handles function name differences, data type conversions, and syntax variations, making database migrations much smoother. What query optimization suggestions does the tool provide? The optimizer identifies common performance bottlenecks that slow down queries. It detects issues like SELECT * usage, missing indexes, inefficient joins, problematic subqueries, and suggests better alternatives. For example, it might recommend using EXISTS instead of IN for better performance, or warn about leading wildcards in LIKE clauses that prevent index usage. How does the minify feature help with production deployment? Minified SQL removes all unnecessary whitespace, comments, and formatting while preserving functionality. This is useful for reducing query size in applications where every byte counts, such as embedded SQL in code or when dealing with query length limits. It solves the pain point of bloated SQL taking up too much space in logs or configuration files. Is this tool suitable for complex enterprise queries? Absolutely! The formatter handles complex queries with multiple JOINs, subqueries, CTEs (Common Table Expressions), window functions, and stored procedures. It maintains proper indentation for nested queries and preserves the logical structure of even the most complex SQL statements. Many developers use it specifically for untangling inherited "spaghetti SQL" in legacy systems. Can I use keyboard shortcuts for faster formatting? The editor supports standard shortcuts like Ctrl+A (select all), Ctrl+C (copy), Ctrl+V (paste), and Ctrl+Z (undo). The ACE editor also provides advanced features like multi-cursor editing, find/replace, and code folding for managing large queries efficiently. What file formats can I upload and download? You can upload .sql and .txt files up to 2MB in size. The tool also supports loading SQL from remote URLs. Downloads are provided as .sql files with proper formatting applied. This solves the common pain point of receiving poorly formatted SQL files from colleagues or extracting queries from various sources that need cleanup.💡 Pro Tip: Use the Query Analysis view to understand complex queries better, or the Schema View to visualize table relationships.
