Frequently Asked Questions
What does SQL escaping do?
SQL escaping converts characters that have special meaning in SQL (primarily single quotes) to safe equivalents. A single quote ' becomes '' (two single quotes) in most SQL dialects. This prevents the value from being interpreted as SQL syntax.
Should I use this for production applications?
No — use parameterised queries (prepared statements) in your application code instead. Parameterised queries separate SQL logic from data completely, eliminating injection risk. Manual escaping is error-prone and should only be used for legacy systems where parameterisation isn't possible.
What is SQL injection?
SQL injection is an attack where malicious SQL is inserted via user input. If a query is built as 'SELECT * FROM users WHERE name = '' + userInput + ''', input of ' OR '1'='1 makes the query return all users. Parameterised queries prevent this by treating all input as literal data, never as SQL.
Is my data stored?
No.
Can I use this on mobile?
Yes.
