[ Part 1 - Introduction ]

If you know (basic) MySQL Injection, you can read this tutorial...

Ok, let's see now what are Load File and Into OutFile.

-- What are Load File and Into OutFile?
That are syntaxes (used in MySQL Injections).

Load File: Reads the file and returns the file contents as a string.
Into OutFile: Writes the selected rows to a file. The file is created on the server host, so you must have the file privilege to use this syntax. File to be written cannot be an existing file, which among other things prevents files (such as "/etc/passwd") and database tables from being destroyed.

Let's see our example:
