Read part 1 for the rationale behind the code.

As discussed in the first part of this blog entry, we'll be utilizing a statement that uses base 36 to generate the random name. We will be adding the $ and _ characters using the ELT function. Here is a true random database and table name generator:

DELIMITER $$
DROP FUNCTION IF EXISTS `randomNameGenerator` $$
CREATE DEFINER=`root`@`localhost` FUNCTION `randomNameGenerator`(

• Allowed characters are a-z, A-Z, 0-9, $, and _
