Frequently Asked Questions (FAQ)
SQL escaping is the process of neutralizing special characters in string literals before embedding them in SQL queries. The most critical character is the single quote ('), which is escaped by doubling it (''). Backslashes are also escaped (\\) in databases that support C-style escape sequences. This prevents the string from prematurely terminating the SQL literal.
SQL escaping is one layer of defense against SQL injection, but it should not be your only protection. The gold standard for preventing SQL injection is using parameterized queries (prepared statements) provided by your database driver. Use this tool for quick escaping when building ad-hoc queries or debugging, but always use prepared statements in production code.
This tool uses ANSI SQL escaping, which doubles single quotes ('' ) and is universally supported by all major SQL databases including PostgreSQL, MySQL, SQL Server, Oracle, and SQLite. Backslash escaping is also applied for databases like MySQL that support it.
This tool escapes three categories of characters: single quotes (' → ''), backslashes (\ → \\), and null bytes (\0). These are the characters most likely to cause SQL syntax errors or security vulnerabilities in string literals.
No. Fuhut runs 100% client-side. All SQL escaping happens entirely inside your web browser using local JavaScript. Your queries and data are never uploaded, stored, or processed on any external server.
