Hi Steve,

I guess Dennis and yourself pointed me to the right direction; no need
the 's around ? and also the parameter substitution requires tuple.
I.e.:

qry.execute("Insert into tBlob (data) values (?)",
(data.encode('hex'),))

Thanks again guys... it's been greatly appreciated by the team here as
well.
