Why are SQL injection attacks so common?

The In-band SQL injection is one of the most common types because it’s simple and efficient. Here, the attacker uses the same communication channel to execute the attack and to collect results.

Which technique is used to help mitigate SQL injection attacks?

Parametrized queries

This method makes it possible for the database to recognize the code and distinguish it from input data. The user input is automatically quoted and the supplied input will not cause the change of the intent, so this coding style helps mitigate an SQL injection attack.
