One type of SQLIA is UNION Query and I still do not completely understand what is the point.
SELECT Name, Address FROM Users WHERE Id=$id by
injecting the following-
Id value: $id=1 UNION ALL SELECT creditCardNumber,1
We will have the following query: -
SELECT Name, Address FROM Users WHERE Id=1
UNION ALL SELECT creditCardNumber, 1 FROM
What is the point of uniting the sqlia with another table which values are being kept secret?
Are main point is to be able to login to the admin for example.
