Re: Column name case conversion

Look at the Interbase solution: they have so called "dialects". Dialect 1
is currently old Interbase 5.x and older. Dialect 2 is intermediate dialect
for easier transition. Dialect 3 is Interbase 6 dialect. They did some
pretty nasty changes between 1 and 3, but you can select in client (ODBC
driver etc.) which dialect you'll use.
