DBI ADO problem


#1

I was wondering if this exception thrown by my use of DBI ADO is
meaningful
to anyone?

c:/ruby/lib/ruby/site_ruby/1.8/DBD/ADO/ADO.rb:141:in finish': undefined methodFields’ for nil:NilClass (NoMethodError)
from c:/ruby/lib/ruby/site_ruby/1.8/dbi/dbi.rb:789:in finish' from c:/ruby/lib/ruby/site_ruby/1.8/dbi/dbi.rb:631:inprepare’

I’m simply trying to call prepare on a method and this looks like some
kind
of internal error within the ADO implementation.

Yes, because I’m getting something similar. However I was using win32ole
directly with the ADO COM objects, using a prepared command, thus
creating and adding parameters.

I can give my version of code if someone needs it.

I looked all over the internet (translation: googled) and couldn’t find
someone who tried to do one of two things: Pass in a nil (NULL on the
DB side) parameter, specified the default value (not sure if there is
a way to do that using ADO, but the FIELDS of the record sets looked
promising), or specified a “no value” for that fields which might allow
the SQLServer provider to use the default.

BTW, a similar error happened when setting a recordset field to nil.

So I’ll piggy back on your question ;).

Related, if someone could use the WIN32OLE ADO api to specify a date,
that would be awesome also :wink:
