[Ruby-DBI-devel] Coerce#as_date("") / repost

[<m_...@mv...>]

# oops, I sent to rub...@ya... ..

hi, all.

I'm using ruby-dbi-all-0.0.13.

When str is "", as_date(str) goes wrong. 
It returns #<DBI::Date:0x... @month=nil, @year=nil, @day=nil>

There is a problem similar to it also in as_time() method.
