Bypassing authentication or checks by incorporating a statement that always returns true, and doing an ‘or’ operation with the statement being injected. It manipulates the return value of the SQL statement to make it always return true, so if the website is checking if the statement returned true to indicate, for example, the password is correct, it will now think that was the case.
What’s the second one do?

I remember the first time I shipped a website with that SQL injection.
It got taken over surprisingly quickly.
