    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,
    P�ter
