What this tool does
SQL string escaping doubles single quotes and applies database-aware rules, while scanning for suspicious tokens commonly seen in injection attempts.
Single quotes are escaped, optional backslash escaping is applied for MySQL-style strings, and risk tokens such as UNION SELECT or DROP TABLE are flagged.
Escaped strings are not a complete security strategy. Use parameterized queries or prepared statements for real application input.
Example
Input: O'Reilly → Output: 'O''Reilly'
Use cases
- Preparing one-off SQL literals
- Escaping names in admin scripts
- Checking suspicious pasted SQL input
- Teaching why prepared statements matter
Tips for better output
- Use prepared statements for user input.
- Avoid concatenating escaped strings into dynamic SQL.
- Treat semicolons and comments as risk signals.
- Choose the database type before copying output.
