SQL Formatter
? Frequently Asked Questions
What does SQL formatting do?
It transforms messy SQL into readable format with proper indentation, line breaks, and keyword capitalization. It makes complex queries easier to understand, debug, and maintain by organizing clauses and subqueries.
Which SQL dialects are supported?
The formatter supports standard SQL and major dialects including MySQL, PostgreSQL, SQL Server (T-SQL), Oracle, and SQLite.
Can it validate SQL syntax?
Some SQL formatters include basic syntax validation, checking for common errors like unmatched parentheses, missing keywords, or invalid clause order. However, full validation requires database-specific parsers.
Does it handle complex queries with subqueries?
Yes! The formatter properly indents nested subqueries, CTEs (Common Table Expressions), joins, and unions. Each level of nesting is indented appropriately, making query structure clear.
Can I customize formatting preferences?
Many formatters allow customization: keyword capitalization (UPPER vs lower), indent size, line breaks before/after clauses, and comma position (leading vs trailing). This matches your team's SQL style guide.
