SQL injection is a technique that exploits a security vulnerability occurring in the database layer of an application. The attack takes advantage of poor input validation in code and website administration. It allows attackers to obtain unauthorized access to the backend database to change the intended application generated SQL queries. Researchers have proposed various solutions to address SQL injection problems. However, many of them have limitations and often cannot address all kind of injection problems.
