SQL::Abstract::Classic was inspired by the excellent DBIx::Abstract. However, in
using that module I found that what I really wanted to do was generate SQL, but
still retain complete control over my statement handles and use the DBI
interface. So, I set out to create an abstract SQL generation module.

While based on the concepts used by DBIx::Abstract, there are several important
differences, especially when it comes to WHERE clauses. I have modified the
concepts used to make the SQL easier to generate from Perl data structures and,
IMO, more intuitive. The underlying idea is for this module to do what you mean,
based on the data structures you provide it. The big advantage is that you don't
have to modify your code every time your data changes, as this module figures it
out.
