Ruby Strings
A String object in Ruby holds and manipulates an arbitrary sequence of one or more bytes, typically representing characters that represent human language. The simplest string literals are enclosed in single quotes (the apostrophe character). The text within the quote marks is the value of the string: 'This is a simple Ruby string literal'
Programs that access MySQL databases can be written in the Ruby scripting language by using Tomita Masahiro's MySQL module. This module provides a Ruby client API; it is implemented as a wrapper around the MySQL C client API. This document describes how to install the MySQL module and use it to write MySQL-based Ruby scripts. A related document describes the Ruby DBI module that provides a higher-level interface that is more abstract and database-independent. See the "Resources" section for a pointer to that document and also for information about downloading the example scripts used here. Obtaining and Installing the MySQL Module

I'm a big fan of the so-called agile programming languages.
