When binary SQL data is converted to character C data, each byte

(8 bits) of source data is represented as two ASCII characters.

These characters are the ASCII character representation of the

number in its hexadecimal form. For example, a binary

<em>00000001</em> is converted to

<em>"01"</em> and a binary <em>11111111</em>
