Yes, all SQL escaping happens locally in your browser. Your queries and data are never sent to any server, keeping your database information confidential.
SQL escaping converts special characters like single quotes into their escaped equivalents. This prevents SQL injection attacks and ensures that special characters in your data do not break SQL queries.
Escaping helps prevent SQL injection by neutralizing special characters in user input. However, for production code, always use parameterized queries or prepared statements as the primary defense. Escaping should be a secondary measure.
The tool handles common escaping patterns that work across most SQL databases including MySQL, PostgreSQL, SQLite, and SQL Server. Different databases may have slight variations in escape sequences.
