This works. But of course it is up to the programmer to ensure that
the qualifier is built in such a way that multiple subclasses do not
overlap.

I've not used single-table inheritance, but I'm pretty sure the
qualifier is just a qualifier and completely independent of columns.
It could be "0 = mod(random(), 2)" if the database supported the
functions.
In this case, the fastest thing to do is to just test your
alternate qualifier.

Hello,
is it necessary to have a full column reserved for the class
qualifier in
case of single table inheritance?
I.e. instead of qualifier
personType = 'CUSTOMER'
would something like
personType like 'C%'
work? Anyone tried such a thing yet?
Thanx in advance,
Péter
