Well yes that works, but why?  In every book I have ever read on SQL
the column names are not in quotes, and the other DB I use regularly
(IBM DB/2) does not require the column names in quotes, and actually
does not recognise the column names if they are in quotes?

I thought SQL was supposed to be standardised these days?  Or are we
in the "standards are a good thing, lets have lots" mode with conflicting
standards or incomplete standards?
