Payloads to try to discover blind SQLi when no error is returned.

payloads.txt

# The situation is the following:
# Your enter ab in a feature and it return data to you but when your enter ab' it indicate that there is not data found.
#
# So, does it means that there is no SQLi because ab' is well handled OR the error is catched
# and a "not data found message" is returned?
#
# The goal here is to submit a payload that, if interpreted by the SQL DB, will give ab and then data will be returned
# then indicating that there is a SQLi because the payload is interpreted.
