Security of web applications is becoming one of the major concerns today. As per the people survey 70% of web applications over the internet are vulnerable to SQL Injection Attacks (SQLIA's). SQL injection attacks pose serious security threat to these databases and web applications. Through SQLIA's attackers gain unrestricted access to the databases of applications and potentially sensitive information. Many methods to address this problem have been proposed in the literature, some having the scope for extension. Methods employ only a subset of the prevention and detection techniques. An extensive survey was done to review and uncover these issues. The paper strongly focuses on the review work of SQL injection attacks and their detection and prevention approaches known to date.
