SQL Injection Attacks (SQLIAs) are one of the topmost threats for web application security, and SQL injections are one of the most serious vulnerability types. Recently the incident of SQLIA is so high. They allow attackers to obtain unauthorized access to the databases. With SQL injections, cyber-criminals can take complete remote control of the database, with the consequence that they can become able to manipulate the database to do anything they wish. SQL injection attack techniques have become more common, more ambitious, and increasingly sophisticated, so there is a deep need to find an effective and feasible solution for this problem in the computer security community.
