This makes making use of the SQL Injection vulnerability harder, however not impossible.

What is blind SQL injection attack can it be avoided?As with regular SQL injection, blind SQL injection attacks can be avoided through the careful usage of parameterized inquiries, which ensure that user input can not interfere with the structure of the designated SQL inquiry.
