Please downcase column names (and everything else that can potentially be downcase'd).  Certain vendors (Oracle) uppercase
all the column names (along with everything else).  This is a pain because then the table attributes must be referred
to in upper case, e.g.

kdbh.select(:Foo){ |f|
   f.SOME_COLUMN_NAME < 300}.each{ |r|
   p r
}
