Is this a bug????

If I run this query:

select objectid,defaulttermsofpayment from prototype.customers
where
objectid = '336A0451-D9E8-7C11-6333-C17DF18E8979'

I get the following answer:

"336A0451-D9E8-7C11-6333-C17DF18E8979";"null"

If I run this query I get *no* results:

select objectid,defaulttermsofpayment from prototype.customers
where
defaulttermsofpayment is null

Is this a bug?
