What are SQL injections and how can they be prevented?

Comment

1. SQL Injection is a code-based vulnerability that allows an attacker to read 
   and access sensitive data from the database

2. SQL injection is one of the most common web hacking techniques.

3. Attackers use SQL injection to alter or update data in the database and add 
   additional data.

How to  prevent SQL Injection  : 

1. Input validation and parametrized queries including prepared statements. 

Some common SQL injection examples are:
a. Retrieving hidden data : where you can modify a SQL query to return additional
   results.
b. Subverting application logic : where you can change a query to interfere with
   the application logic.
c. UNION attacks:  where you can retrieve data from different database tables.
