What is SQL injection ?
SQL injection is a hacking technique which is widely used by black-hat hackers to steal data from your tables or databases. Let’s say, if you go to a website and give in your user information and password, the hacker would add some malicious code over there such that, he can get the user information and password directly from the database. If your database contains any vital information, it is always better to keep it secure from SQL injection attacks.
