what is sql Injection?..

Answer / srikant dwibedi

SQL Injection is he process of passing SQL code into an
application in a way that was not intended by the
application developer or it is a strategy for attacking
databases.

Example
An ASP page asks the user for a name and a password.
SELECT FROM users WHERE username="whatever" AND
password="mypassword".
It seems safe,but it is not. A user might enter somthing
like this 'OR 1>0....
when this is plugged into the SQL statewments the result
looks like this:
SELECT FROM users WHERE username="OR 1>0 " AND
password=" ";
This injectin comments out of the password portion of the
statement. It results in a list of all the names in the
users table. So any user could get into your system.
