    Don't know Informix details, but generally DbAdapter takes care of
    that in a db-specific manner. Our Informix adapter effort got stuck
    for now [1]. So I suggest to first check whether
    ExpressionFactpry.likeIgnoreCaseExp() works. If it doesn't, you have
    two choices - customize the adapter for Informix or use SQLTemplate.
