> like in mysql, HEX could take int or string arguments, For a integer argument
> N, it returns a hexadecimal string representation of the value of N. For a
> string argument str, it returns a hexadecimal string representation of str
> where each byte of each character in str is converted to two hexadecimal
> digits.
> Syntax:
> HEX(100) = 64
> HEX('This is a test String.') = '546869732069732061207465737420537472696e672e'
