SQL Injection demonstration: Why parameterized prepared statements are mandatory
Concatenating user input directly into SQL strings (`'SELECT * FROM users WHERE name = '' + input + '''`) allows input like `' OR '1'='1` to bypass all authentication. Prepared statements separate query bytecode compilation from parameter data values, making injection physically impossible at the database driver level.
