What is SQL Escaping?

SQL escaping is the process of making string values safe to include in SQL queries by converting special characters that could break the query or cause SQL injection vulnerabilities.

The most common escape in SQL is doubling single quotes: a single quote ' becomes ''. Backslashes may also need escaping depending on the database.

Always escape user-supplied input before including it in SQL queries to prevent SQL injection attacks. This is a fundamental security practice.
