Hmm -- I'm not sure if I had a good reason for the WHERE 1=1, although I
think I tried it without first.

Maybe it was needed to stop CDBI putting a where clause in, or maybe it
was superstition, or I just thought it looked big and clever? Thanks for
your input -- it's all helpful to me!

Yup, I like that, and also the slightly more obvious class/instance
seperation in DBIxC vs CDBI. (As much as I find any Perl "obvious", anyway.)

Also like that I can swap between DBs (SQLite -> MSSQL) just by changing
the DSN, in CDBI I was using a different base class to get the autoinc
columns working.

However, it's a bit slow joining all the DBIxC bits together in my head
-- is there a class diagram somewhere? [not sure if I'm joking or not :-/ ]
