Then you can still use another method, not really sure what the real term for it is (if anyone knows, please let me know), I call it the blindfold mode.
It’s like slowly brute forcing, since you can manipulate the where query to fit your needs and will be told wether or not this query got a result or not.
So for example, if you have a user and you need the email, you would do queries such as this until you find the match:

Code

WHERE email LIKE "a%”

This will success if the email starts with “a”, if not continue and try it with “b” and so on.
Once you find the first letter, continue to the next

Code

WHERE email LIKE "sa%”

In the above we know it starts with “s” and are now testing if the second letter is “a”.
And in the end you could end up with a query like this

Code

WHERE email LIKE "[email protected]%”

If you wanna test if you have the full email already, you simply remove the ending “%”

Code

WHERE email LIKE "[email protected]”

If this is successful, you have gathered the full email.
